L4M3 Sample Questions Answers

KPIs and the targets for supplier should be SMART:

- Specific: What exactly do you want to achieve?

- Measurable: How will you identify that you have achieved your goal?

- Achievable: Is your goal really attainable?

- Relevant: Is it relevant to you or, in other words, does it align with where you want to be?

- Time-bound (or timely): When will you deliver your goal, and what are the key milestones?

The two KPIs (Delivery in one hour, Return orders in one hour) are not realistic and achievable for international suppliers. Therefore, you should not put such high targets for supplier.

The complexity of the contract will reflect the complexity of the purchase. For simple, low-value purchases, standard terms and conditions may be all that is required, but do not assume that just because the purchase is one-off, the contract will be simple. It may still need to cover the following areas:

- Warranties and guarantees if the one-off purchase has a considerable life-span and is business-critical (e.g., a back-up generator for the office which houses the national computer servers).

- Insurance requirements: including professional indemnity, public/products liability, employer's liability, and cover for any specific risks such as pollution or working at height.

- Specification requirements on quality, timing and delivery

- Minimum quality standards on the business operation (e.g., a catering provider might only be providing sandwiches for a team meeting lunch, but you still need to know its hygiene practices).

- Built-in change process for any goods or services that are beyond very simple (e.g., works contracts always have variations procedures because of the unpredictable nature of such projects).

- Ability to extend the scope of the contract should be minimal or none, and restrained to the single requirement.

- Ability to extend the duration of the contract should be limited to the ability to accommodate unexpected time overruns (which itself should be subject to a damages/penalty provision where they are attributable to the supplier, and an extension to overheads costs where they are attributable to the purchaser).

- Data security protocols need to be considered if personal data is being shared.

There are two main types of specification: performance specification and conformance specification (sometimes called prescriptive or technical specifications).

Performance specifications have following features:

- Focus on outputs

- Set out result to be achieved

- The 'what', not the 'how'

- Give supplier flexibility to present solutions that the buyer may not have considered

To solve the question, you must distinguish the following notion:

- Offer: The case of Storer v Manchester City Council [1974] 1 WLR 1403 outlines that an offer is: An expression of willingness to contract on specified terms, with the intention that it is to be binding once accepted

- Acceptance: in order for a contract to be formed, the offer must be accepted. Acceptance represents the meeting of the minds of the parties to the contract – both agree to exchange something for the other (payment, services, goods, etc.).

- Counter offer: is an offer made in response to a prior offer.

- Invitation to treat: An important distinction to make in contract law is that between an offer and an invitation to treat. An invitation to treat is usually an invitation for another party to make an offer. It may also be defined as an indication that a party is open to negotiation.

Here are some key distinctions of offers and invitation to treats.

Offer:

* Certain promise to be bound

* Clear and specified terms

* The conduct or words of the party show certainty

* There is no room for negotiation

Invitation to treat:

* There is room for negotiation

* There is an invitation for offers

* There is a request for information

* Lack of certainty

In the scenario above, initially Michelle just gives an invitation to treat because she is asking whether Hannah is interested to buy her car (request for information from Hannah). Hannah may reject or go into a negotiation with Michelle. Then, Hannah makes an offer by taking the money and shows her intention to be legally bound. At this point, when Hannah's offer is present, Michelle can accept or reject. When she rejects, the contract is not formed. The answer must be "No, because Michelle has rejected Hannah's offer on buying the car".

This question is intended to let students know about how contractual clauses regarding ethical issues is constructed. The exam paper may not ask about this.

"Each Party hereby undertakes that, at the date of the entering into force of the Contract, itself, its directors, officers or employees have not offered, promised, given, authorized, solicited or accepted any undue pecuniary or other advantage of any kind in any way connected with the Contract and that it has taken reasonable measures to prevent subcontractors, agents or any other third parties, subject to its control or determining influence, from doing so.": This is a clause addressing fraud, bribery and corruption. It is created to prevent any undue act by contracting parties. You may find other anti-corruption clause samples in this document.

"Nothing in this Agreement shall prevent a Party from utilizing the services of any subcontractor as it deems appropriate to perform its obligations under this Agreement; provided, however, that each Party shall require its subcontractors to comply with all applicable terms and conditions of this Agreement in providing such services and each Party shall remain primarily liable to the other Party for the performance of such subcontractor.": This clause is used to control the subcontracting and subcontractors.

"Customer will be responsible for and shall ensure that while Service Provider employees, agents or contractors are on Customer’s premises, all proper and legal health and safety precautions are in place and fully operational to protect such persons.": This clause is used to ensure health and safety standards.

"The Company has undertaken commercially reasonable efforts to eliminate Conflict Minerals from each Company Product and any products currently proposed to be manufactured by the Company or on its behalf in the future. “Conflict Minerals” means columbite-tantalite (coltan), cassiterite, gold, wolframite, or their derivatives, which originate in the Democratic Republic of the Congo or other country the exploitation and trade of which is determined by the United States to be financing conflict in the Democratic Republic of the Congo or other country.": This is a clause addressing conflict minerals.

Express terms are the terms of the agreement which are expressly agreed between the parties. Ideally, they will be written down in a contract between the parties but where the contract is agreed verbally, they will be the terms discussed and agreed between the parties.

Implied terms are terms implied into the contract by the courts. They are not expressly set out in the contract but are taken to be as effective as if they were and as if they had been included from day one of the contract. The express terms and any implied terms together create the legally binding obligations on the parties.

Direct call off is the act of placing an order under a framework agreement without having further competition.

Standing offer is an available offer.

Blanket order is another name of framework agreement

Closed system is a requirement of framework agreement. It is a system or process that, once started, does not allow new entrants.

Consideration is one thing given in exchange for another.

In this case, considerations of customers are three wrappers and 1s6d. Consideration of Nestle is Rockin' Shoes record or a voucher.

Advantages and Disadvantages of using model form contracts.

Model form contracts save a lot of time and money. They are written by industry experts and the buyers and suppliers both understand what is included in the contract.

They are mainly used in Construction and term maintenance contacts. Typical ones are JCT and NEC.

Without the use of model form contracts the buyer and supplier will take a long time to write the terms, negotiate and finalise the contract.

This is time and money wasted.

However, model form contracts require buyers and suppliers to have training so you understand them.

Finally, if you are a buyer in a powerful position you cannot exploit that with a model form contract as these are written for mutual benefit.

Standard terms and conditions are set of terms that is prepared by an organisation. These terms can become the governing terms in low-value, low-risk transactions (or Routine items according to Kraljic's portfolio model). They can be a reference when negotiating for more important contract.

Express terms are the terms of the agreement which are expressly agreed between the parties. Ideally, they will be written down in a contract between the parties but where the contract is agreed verbally, they will be the terms discussed and agreed between the parties.

The types of express terms to be found in a contract are many and varied and will depend on the type of contract. Any term written into the contract is an express term and may refer to price, time scales, warranties and indemnities, limitations on liability, conditions precedent and so on.

Social and environmental criteria are increasingly encouraged in public sector contracting. In the UK, The Public Services (Social Value) Act 2012 encourages public organising to apply social and environmental criteria in contract.

In the contract term, the buyer agrees to pay the contractor the cost of doing project plus a profit. This is an example of cost-plus pricing arrangement.

On the other hand, "Fixed-pricing arrangement" often refers to lump-sum contract or supply/service contract with fixed price. "Incentive pricing arrangement" and "Gain-share/pain-share arrangement" have the same meaning. In this type of arrangement, both supplier and buyer agree on a target (it can be cost, or lead time, or quality, etc). Once the supplier reaches that target, it will be rewarded with a portion of the gain that the buyer gets, and will pay the price if it fails.

A simple definition of consideration is as follows – an exchange between the parties which results in a benefit to one party, and a detriment to the other. The case of Currie v Misa (1874) LR 10 Ex 153 provides an apt description of this:

“A valuable consideration, in the sense of the law, may consist either in some right, interest, profit, or benefit accruing to the one party, or some forbearance, detriment, loss, or responsibility, given, suffered, or undertaken by the other.”

A practical example of this can be found by examining a simple contract. Party A offers £500 to Party B, who in exchange will fit his car with a new engine. Party A receives the benefit of his car being fixed, whilst Party B incurs the detriment of having to take time, effort, and perhaps expenses to fix the car.

If a service level agreement is used as a schedule to a contract, it will generally have the following contents:

- Service definitions. If the service information is provided by the specification, SLA should only refer to the specification to avoid any inconsistencies.

- Details on how to measure KPIs, who will measure KPIs

- Minimum requirements or targets

- Remedies if the minimum requirements are not met

Since SLA often lists out the KPI targets, consequences for not meeting the KPI targets and remedies to situation of poor performance, it is a part of performance management.

The contract provision that relieves the parties from performing their contractual obligations when certain circumstances like natural disasters, terrorist attacks, etc arise is called Force majeure. Force majeure is an example of exclusion clause.

An exemption clause in a contract is a term which either limits or excludes a party’s liability for a breach of contract. In order for an exclusion clause to be binding and operable upon the parties, the clause must:

1. The clause must be incorporated into the contract as a term.

2. The clause must pass the test of construction.

3. The clause must not be rendered unenforceable by the statutory provisions in the Unfair Contract Terms Act 1977 or the Consumer Rights Act 2015 (enacting the Consumer Rights Bill 2013-14).

Lead time is the amount of time that passes from the start of a process until its conclusion. In procurement, lead time can be understood as the amount of time that passes from placing an order until the delivery.

In the scenario, the contract requires the supplier to make a delivery within 3 days since the order. This contract can only be amended with written consent from both parties. Therefore, there is no ground for shortening the lead time to 1 day because the new lead time is only the request of buyer. Then the supplier still makes delivery within agreed lead time.

GHS stands for the Globally Harmonized System of Classification and Labelling of Chemicals. GHS defines and classifies the hazards of chemical products, and communicates health and safety information on labels and safety data sheets). The goal is that the same set of rules for classifying hazards, and the same format and content for labels and safety data sheets (SDS) will be adopted and used around the world. An international team of hazard communication experts developed GHS.

The Global Positioning System (GPS), originally NAVSTAR GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Obstacles such as mountains and buildings block the relatively weak GPS signals.

CODEX STAN 1-1985 is general standard for the labelling of packaged goods.

Environment (E), health (H) and safety (S) (together EHS) is a discipline and specialty that studies and implements practical aspects of environmental protection and safety at work. In simple terms it is what organizations must do to make sure that their activities do not cause harm to anyone.

There are a number of ways for an offer to be terminated. They are events that may occur after an offer has been made which bring it to an end so that it can no longer be accepted. An offer is terminated in the following circumstances:

1. Revocation

2. Rejection

3. Lapse of time

4. Conditional Offer (or Failure of Conditionality)

5. Operation of law

6. Death

7. Acceptance

8. Illegality

Request for quotation has valuable function when its use is properly controlled. It works the best under framework agreements where the contract terms are already fixed.

Advantages of using fixed pricing arrangement are as below:

- Budget/income certainty - prices are fixed up front and should not change

- The impact of changes to the supplier's cost base is not fed through to the purchaser. If costs diminish, the supplier will benefit from this, and if costs rise, the purchaser will benefit

Many firms have compliance policies for suppliers in place. To ensure that the supplier actually comply with the standards set out, the purchaser can employ the right to audit. The buyer usually obtains the right to examine records of a vendor to determine if a fraud or a violation of company policy has occurred through the following methods:

- Right-to-audit agreement The agreement can be printed on the back of a purchase order, contract, or other procurement form.

- A simple request If the right-to-audit agreement wasn't included on the procurement form, and the buyer suspects irregularities, he may have to beg the vendor to allow an audit to be performed. If the buyer is a major customer of the vendor, the buyer may be able to wield a big enough stick to obtain permission to look at the records.

- Right-to-audit Pitfalls

Mark up is the profit as a percentage of total costs.

LO 3, AC 3.3

When a written contract is based on oral negotiation, to avoid the conflicts between orally negotiated terms and final written contract, the contract should include an express term that specifically excludes all prior oral discussion. However, orally negotiated terms can be used to interpret the final contract.

This practice (excluding prior discussion) is so common in international commercial contract that UNIDROIT Principles of International Commercial Contracts have an article (2.1.17) dealing with this.

Standards are incorporated into specifications by simply cross-refering to the relevant standard by its number and date of publication. It is important to include the date of publication. All standards are reviewed from time to time and their content changes. The absence of the publication date will lead to disrupts over which version of the standard actually applies to the contract.

According to the scenario, customers' demand changes regularly but the construction project commencement often delays. If the contractor and the customer mutually sign a legally binding contract too soon long before the commencement, the contractor may suffer poor cash flow (it must buy the materials first but has to wait for long time to be paid). A framework agreement may help both parties.

A framework agreement is a formal agreement between two organisations that is intended to become legally binding in the event that a contract is created.

A framework agreement could benefit the both parties in the following ways:

- At the time of signing, the framework agreement has not yet become a legally binding contract. The contractor and client only agree on the principles of future contracts (such as whether the work can be subcontracted or how payment will be proceeded). A well structured framework agreement will allow both parties to apply changes before contract commencement, especially regarding price and quality.

- The framework agreement assures a certainty between the contractor and client.

- The administrative works is reduced under a framework agreement.

There are 2 major types of specifications:

1. Performance specifications

These are Specifications that define the purpose of the goods or services in terms of how effectively it will perform. Performance is a logical extension of function. Performance specifications define the task or desired result by focusing on what is to be achieved. They do not describe the method of achieving the desired result.

2. Technical (or conformance) specifications

These are Specifications that define the technical and physical characteristics and/or measurements of a product, such as physical aspects (e.g. dimensions, colour, and surface finish), design details, material properties, energy requirements, processes, maintenance requirements and operational requirements. They are used when functional and performance characteristics are insufficient to define the requirement and are often used for engineering and information technology requirements.

The request for quotations is a procurement method that is used for small value procurements of readily available off-the-shelf goods, small value construction works, or small value services procurements. Request for quotations works best under a framework agreement

This procurement method is also known as invitation to quote and shopping, and it does not require the preparation of tender documents to the same extent as open tendering, request for proposals or two-stage tendering.

Among 4 options:

- "Purchase of a small number of standardised products under a framework agreement": the products are standardised and there is a framework agreement in place, so RFQ is the best solution.

- "Purchase of complex machinery": Complex machinery is often a large purchase. Furthermore, suppliers' quality may vary. So RFQ is not suitable, instead, depending on the situation, buyer may opt ITT or RFP to purchase this type of machinery.

- "Design of a unique and complex software code": Unique and complex software is not off-the-shelf, thus RFQ is not suitable.

- "When the buying organisation does not know the requirements in details and needs the input from suppliers": When the detailed requirements are unknown, the best solution is request for proposal or developing dialogue with suppliers.

United Nations Convention on Contracts for the International Sale of Goods (Vienna Convention or CISG)

Vienna Convention was prepared by by the United Nations Commission on ¬International Trade Law (UNCITRAL) and adopted by a diplomatic conference on 11 April 1980. The Convention was welcomed by several countries from different geographic areas, with different legal and political systems. As of 20 August 2020, the Convention has93 Contracting States. The Convention has proved the effectiveness of an uniform text on international trade law.

What CISG covers, and what it does not

In the 6 first articles of the Convention, the authors set up the boundaries of its application.

First is about where it applies. According to UNCITRAL, the Convention applies to contracts of sale of goods between parties whose places of business are in different States and either both of those States are Contracting States or the rules of private international law lead to the law of a Contracting State. A few States have availed themselves of the authorisation in article 95 to declare that they would apply the Convention only in the former and not in the latter of these two situations. As the Convention becomes more widely adopted, the practical significance of such a declaration will diminish. Finally, the Convention may also apply as the law applicable to the contract if so chosen by the parties. In that case, the operation of the Convention will be subject to any limits on contractual stipulations set by the otherwise applicable law.

Second, the Convention has a list of goods that are not subject to its application in Article 2. Article 3 clarifies the differences between manufacturing contracts and sale contract.

Third, Article 4 and 5 clearly states what CISG does not covers, including grounds for contract invalidity and liabilities to death or injury of person caused by the the goods

Finally, the Convention respects the contractual freedom of the trading parties. Trading parties may select this convention as governing law or select other instrument, such as UPICC or domestic laws.

When a party takes on a contractual obligation, they are legally required to perform the obligation.

That same contracting party is still entitled to subcontract out the work to another service provider, unless the contract:

- is a contract for personal services, such an employment contract

- contains an express term preventing subcontracting out the work, or an implied term

Subcontracting clauses are written to control whether the contractor is entitled to subcontract, and how purchaser shall control that subcontracting process.

Without further explanation, a schedule may be deemed to form an integral part of the obligations of either or both parties. Obviously, the scope or binding nature of such schedule depends on the way it is referred to in the obligatory language of the main agreement. Accordingly, merely attaching the general terms and conditions of sale without explaining to which part of the sale they apply or which provisions apply does not subject a sale pursuant to the body text of the agreement to those general terms and conditions.

Subcontracting is the practice of assigning, or outsourcing, part of the obligations and tasks under a contract to another party known as a subcontractor.

Regarding rule of offer and acceptance, there are some differences among legal system around the world. For example, mailbox rule is generally applied in common law countries such as UK, US, Australia,.. while it is ignored in civil law countries. To clarify on rule of offer and acceptance in international trade, offerors may use expressed terms in their offers. These terms known as deemed receipt protocol.

One-off contracts are used where a supplier is only needed for a single activity unlikely to be repetitive, and where the need of the buyer is concrete and finite. Among the answers, only construction for power plant is one-off since the work is non-repetitive and the need is clearly defined.

A framework agreement is an agreement between one or more businesses or organisations, "the purpose of which is to establish the terms governing contracts to be awarded during a given period, in particular with regard to price and, where appropriate, the quantity envisaged".

A Commercial Lease Agreement is a contract used when renting business property to or from another individual or company. It gives the tenant (or renter) the right to use the property for business purposes during the term of the lease in exchange for payment to the landlord.

A franchise agreement is a legally binding document that outlines a franchisor's terms and conditions for a franchisee. Every franchise is governed by these terms, which are generally outlined in a written agreement between both parties.

Once a valid acceptance takes place, a binding contract is formed. It is therefore important to know what constitutes a valid acceptance in order to establish if the parties are bound by the agreement. There are three main rules relating to acceptance:

1. The acceptance must be communicated to the offeree.

2. The terms of the acceptance must exactly match the terms of the offer.

3. The agreement must be certain.

Among the answers:

"The person says that she will think about it overnight" does not match the terms of the offer. The offeree does not assure that she will accept the offer.

"The person asks for a lower price": This is a counter-offer.

"The person states that she is able to pay the offered price" is not certain. The offeree merely provides information on her financial ability.

Implementation is a substantive requirement which covers the following areas:

- Will there be a need to train the staff to use the equipment?

- Are there integration requirements with other systems or processes?

- How will this work?

- What are the timescales?

- Are detailed method statements required?

Consultation requirements regards to explicitness of compliance with any national or local legal requirements

Performance management framework often consists of KPIs, targets and consequences that arise from achieved scores. To ensure that the framework has binding effect on contracting parties, it should be developed, appended to the main contract document and agreed by both parties. So the answer should be "Yes, because the framework should have legal standing as a part of contract".

The key features, advantages and disadvantages of standard terms are summarised below:

- Form: Concise, generic and designed to be attached to purchase or sales orders

- Non-negotiable

- Ineffective terms: may be replaced by implied terms or national legal code rules, or subject to court 'balance of interest' judgement.

- Advantages: Basic contractual protection for most common circumstances; Avoid having to create new contract for repeat business.

- User friendly

- Usage: Low value, low risk, repetitive transactions

- Coverage: Definitions, relationship to other contracts, formation of the contract, order of precedence, price, invoicing and payment, specification, legal compliance, warrantee and liability, ownership and risk, intellectual property, data management and ethics.

- Disadvantages: Does not allow for specific circumstances; Risk for creating battle of the forms; Can create contractual uncertainty if used with purchase orders under call-off contracts.

There are number of reasons why the purchaser will want to control the supplier's subcontracting:

- Supply chain transparency: Normally the purchaser has invested a lot of effort into selecting the right contractor. However, the main contractor's selection of subcontractor might not be in such careful manner, which may result in poor performance. Purchaser must know who subcontractors are. Controlling the subcontracting process can help the purchaser control the outcome.

- Contract terms: the purchaser's requirements must be reflected in the subcontracts. The subcontracting clauses may require the main contractor to do this.

- Liability: the main contractor may subcontract the whole or a part of its liabilities. Subcontracting clause may bind the contractor to be liable with the work, it cannot just blame the subcontractor for any faults.

An incentive contract is a sub-segment of a fixed-price or cost-reimbursement contract when there are specific cost or time commitments that are desired for a project. The standard incentive contract will allow for a fixed price to be paid for work to be completed by a specific deadline and at a specific cost.

There are two major types of incentive contracts: Cost-plus-incentive fee and Fixed-price incentive (firm target) contracts. Both types have the same formula for calculating final fee and final price.

The target fee is the amount that will be paid if the actual costs (which can be proven) match the target costs

The actual fee will be adjusted in proportion to the difference between the target cost and the actual cost. The usual calculation is:

Target fee + ((target cost - actual cost) x Supplier share) = final fee

The final price then becomes:

Actual cost + final fee = final price

Retention money is the payment for a service or product that is withheld pending the completion of some specified condition. For example, buyer may withhold the amount due until the supplier replace all defective goods.

Pay-less notice is the notice under a contract which states that the invoice will only be partially paid because of some issues such as supplier has to pay the damages.

Remedies for late payment are remedies that supplier may seek when a buyer pay it later than the stated payment terms. Normally, the buyer will be charged an interest rate.

Express terms are the terms of the agreement which are expressly agreed between the parties. Ideally, they will be written down in a contract between the parties but where the contract is agreed verbally, they will be the terms discussed and agreed between the parties.

Implied terms are terms implied into the contract by the courts. They are not expressly set out in the contract but are taken to be as effective as if they were and as if they had been included from day one of the contract. The express terms and any implied terms together create the legally binding obligations on the parties.

The types of express terms to be found in a contract are many and varied and will depend on the type of contract. Any term written into the contract is an express term and may refer to price, time scales, warranties and indemnities, limitations on liability, conditions precedent and so on.

An implied term is a term which the courts imply into a contract because it has not been expressly included by the parties. This may be because the parties did not consider it, did not think that any problem would arise in relation to it or simply omitted to include it.

The courts are very reluctant to imply terms into contracts and will only do so in the following circumstances:

1. terms implied under statute

2. terms implied under common law

3. terms implied because of custom or usage

4. terms implied due to previous dealings

5. terms implied ‘in fact’ or to reflect the parties’ intentions

There are three key components of a performance management framework:

- Key performance indicators (KPIs) - What you are measuring

- Targets - the performance level to be achieved

- Consequences - what happens if the measures are not achieved and/or if they are exceeded

A misrepresentation is a false statement of fact or law which induces the representee to enter a contract. Where a statement made during the course of negotiations is classed as a representation rather than a term an action for misrepresentation may be available where the statement turns out to be untrue.

For a party to claim for misrepresentation, there must be a false statement of fact or law as oppose to opinion or estimate of future events. It does not matter whether the incorrect information is given by words or takes the form of misleading conduct.

Silence will not generally amount to a misrepresentation. However, it can become a misrepresentation in some exceptional circumstances.

In the L4M3 study guide, the author states that "A statement of law is not misrepresentation". This is untrue in both common law and civil law systems. In the UK, false statement of law will now amount to an actionable misrepresentation (see Pankhania v Hackney [2002] EWHC 2441).

A contract for window cleaning during the next three months is a short-term service contract in which changes of input costs (labour, tools,...) are very unlikely to happen.

Fixed pricing arrangement is useful for small to medium scope project, with short timelines, where what is delivered can be adequately specified and the likelihood of changes to the specification, scope and input costs is limited.

Liquidated damages, also referred to as "liquidated and ascertained damages" (LADs) are damages whose amount the parties designate during the formation of a contract[2] for the injured party to collect as compensation upon a specific breach (e.g. late performance). In supply contracts and work contracts, the liquidated damages clause often take form as known damages to be paid per day delayed. Number 1 and 2 are examples of this clause.

Variable pricing is suitable to situations when the cost of certain elements of the product fluctuate unpredictably. For road building, asphalt fluctuates regularly. Furthermore, 5 years are long period, then variable pricing is the most appropriate method to achieve value for money and control budget.

A contract for window cleaning during the next three months is a short-term service contract, fixed price is the most suitable method.

A contract for the supply of lubricating oil for immediate delivery is an one-off contract, only fixed price is applicable.

A contract for the supply of 100 printing machines to be delivered next month is also an one-off contract.

An offer is a full statement of what the offeror is willing to provide and the terms by which they are willing to provide it.

There are some statements that are not offers:

- Invitation to treat: this states that a person or organisation is willing to enter into discussions about the possibility of a deal, but does not confirm a willingness to be bound by any terms mentioned. Catalogues, goods on display and ITTs are invitation to treat.

Civil law countries may have different perspective on this matter. Article 2:201 (3) of The Principles of European Contract Law states: 'A proposal to supply goods or services at stated prices made by a professional supplier in a public advertisement or a catalogue, or by a display of goods, is presumed to be an offer to sell or supply at that price until the stock of goods, or the supplier's capacity to supply the service, is exhausted.' Learners are advised to look at their countries' legislation for more information on offer and acceptance.

- Declaration of intention: this is defined as an aim or a plan.

- A 'mere puff' (or boast): this is anything which is not intended to be taken literally or seriously, such as many advertisement.

- Provision of information: merely provides information, but provider does not confirm willingness to be bound.

Quantum meruit means "the amount he deserves" or "as much as he has earned". In most cases it denotes a claim for a reasonable sum in respect of services or goods supplied to the defendant.

An action in quantum meruit is available to recover money for services or goods supplied to a defendant in circumstances where the claimant is not recompensed by performing his obligations or supplying the goods. The claimant must usually show that the defendant expressly or impliedly requested or freely accepted the services or goods in question. Depending on the facts, the claimant might find it difficult to prove how much the claimant is entitled to receive under the principle of quantum meruit.

A claim for quantum meruit cannot arise if the parties have a contract to pay an agreed sum. In such circumstances, the parties' relationship is governed by the law of contract. However, a claim for quantum meruit may arise where the parties:

- Have not agreed a contract, or there is a so-called quasi-contract. For example, the parties may have agreed some of the contractual terms, but may have failed to reach an agreement on an essential term, such as price.

- Have not fixed a price for the services or goods supplied.

- Have an agreement to pay a reasonable sum for the services or goods supplied.

- Have agreed a scope of work under the original contract and the work carried out falls outside that scope.

A service-level agreement (SLA) is a commitment between a service provider and a client. Particular aspects of the service – quality, availability, responsibilities – are agreed between the service provider and the service user. The most common component of an SLA is that the services should be provided to the customer as agreed upon in the contract.

A customer service charter is a document that outlines how an organization promises to work with its customers along with providing insights into how an organization operates.

A service guarantee is a marketing tool service firms have increasingly been using to reduce consumer risk perceptions, signal quality, differentiate a service offering, and to institutionalize and professionalize their internal management of customer complaint and service recovery.

An invitation to treat is an action inviting other parties to make an offer to form a contract. These actions may sometimes appear to be offers themselves, and the difference can sometimes be difficult to determine. The distinction is important because accepting an offer creates a binding contract while "accepting" an invitation to treat is actually making an offer.

One simple test to distinguish an offer and an invitation to treat is to ask what this statement will become when it is accepted. Now we apply this test to four options:

- Tender bid: Tender bid is submitted by a supplier to an invitation to tender from the buyer. It states the specific quantity, price and other elements. If buyer accepts the bid, there will be a contract between them. Therefore, a tender bid is an offer.

- Purchase order: Purchase order which is sent by a buyer will state the items, the quantity, the price and terms and conditions. If supplier accepts the purchase order, there will also be a contract between two parties. It is also an offer.

- Price list: Price list is prepared by a supplier. The price list often states the items and unit price. If a buyer accepts it, the contract has not yet been formed since the contract scope has not yet been decided. It is an invitation to treat.

- Invoice: Invoice is often sent after a contract is formed. It is in fact a request for payment, neither offer nor invitation to treat.

In common law (the legal system in which most rules come from case law or precedents, such as UK, US, Australia, etc), the contract is legally binding if it has the following requirements:

- Offer

- Acceptance

- Certainty & Intention to Create Legal Relations

- Consideration & Promissory Estoppel

- Legal capacity

According to these rules, 'Blanket order', 'One-off purchase', and 'Hire purchase agreement' are contractually binding. One of the reason is that they have consideration.

However, there is a type of legal instruments that does not need consideration to be legally binding. They are called 'Deeds'. A deed (anciently "an evidence") is any legal instrument in writing which passes, affirms or confirms an interest, right, or property and that is signed, attested, delivered, and in some jurisdictions, sealed. It is commonly associated with transferring (conveyancing) title to property. At common law, to be valid and enforceable, a deed must meet several requirements:

- It must state on its face that it is a deed, using wording like "This Deed..." or "executed as a deed".

- It must indicate that the instrument itself conveys some privilege or thing to someone.

- The grantor must have the legal ability to grant the thing or privilege, and the grantee must have the legal capacity to receive it.

- It must be executed by the grantor in presence of the prescribed number of witnesses, known as instrumentary witnesses (this is known as being in solemn form).

- In some jurisdictions, a seal must be affixed to it. Originally, affixing seals made persons parties to the deed and signatures optional, but seals are now outdated in most jurisdictions, so the signatures of the grantor and witnesses are primary.

- It must be delivered to (delivery) and, in some jurisdictions, accepted by the grantee (acceptance).

There are a number of shortcuts that can be taken when drafting the specification. These include the following:

- The use of brand names

- The use of recognised standards

- The use of samples

- Information and knowledge from users/other buyers: Drafting a specification should naturally include those already used within the organisation itself, but also variants used by other companies in the same sector and other companies in different sectors

- Information from suppliers: suppliers will always be willing to assist in specification development, as this this one way in which they can seek to influence the design to favour their own products.

- Strict liability, sometimes called absolute liability, is the legal responsibility for damages, or injury, even if the person found strictly liable was not at fault or negligent. Strict liability has been applied to certain activities in tort, such as holding an employer absolutely liable for the torts of her employees, but today it is most commonly associated with defectively manufactured products. In addition, for reasons of public policy, certain activities may be conducted only if the person conducting them is willing to insure others against the harm that results from the risks the activities create.

- Current liabilities are a company's short-term financial obligations that are due within one year or within a normal operating cycle.

- Non-current liabilities, also called long-term liabilities or long-term debts, are long-term financial obligations listed on a company’s balance sheet

- Contingent liability is a potential liability that may occur, depending on the outcome of an uncertain future event.
