What is the Difference Between an Offer and an Invitation to Treat in the UK?

Summary

  • An invitation to treat is a statement inviting others to make an offer, while an offer is a clear proposal that creates a binding contract if accepted. 
  • Invitations to treat are not legally binding and cannot be accepted to form a contract. 
  • Common examples include advertisements, shop displays and online listings, where the customer makes the offer. 
  • This guide explains the difference between invitations to treat and offers for business owners in the UK, prepared by LegalVision, a commercial law firm that specialises in advising clients on commercial contracts.
  • It provides a practical explanation of how wording and conduct affect whether a binding contract is formed.

Tips for Businesses

Clearly distinguish between offers and invitations to treat in your communications. Use wording that avoids unintended contractual obligations. Treat advertisements and listings as invitations, not binding offers. Review sales terms carefully to ensure contracts only form when you intend them to.

An invitation to treat is a preliminary step in negotiations that invites others to make an offer, while an offer is a clear proposal that becomes legally binding once accepted. For your business, confusing the two can create unintended contracts or leave you without enforceable rights, especially in pricing, advertising or negotiations where wording matters. You must clearly structure communications to control when you are legally bound and avoid disputes. This article explains the difference between an invitation to treat and an offer, with practical examples for UK businesses.

What Makes a Binding Contract?

When you make a contract with another party, such as a customer, there are certain elements it must have for it to be legally binding. That means that without all of these factors, it is unlikely you can successfully take legal action against the other party if they do not fulfil their obligations. The four main elements of a binding contract are:

  • an offer: one party proposes terms to another;
  • Acceptance: the other party agrees to its terms;
  • Consideration: both parties exchange something of value, such as money or services; and
  • intention to create legal relations: both parties must intend to be legally bound.

The contract is then usually made binding by signing a written document or an action that is considered of ‘acceptance’. For example, by ticking a box that has wording to this effect: ‘by ticking this box, I accept these terms and conditions.’

Importantly, an offer by either you or the other party is the first step to making a contract. The offer usually includes a promise you will undertake if it is accepted. This can be to, for example, provide a good or service to the other party.

What is an Invitation to Treat?

An invitation to treat is a situation in which someone invites another person to make them an offer for an item, service or goods. It is akin to asking someone to ‘make you their best offer’. Importantly, you are not bound to accept the sum they suggest. 

This is usually an excellent strategy to get a potential customer or fellow company to initiate negotiations. In doing so, you may obtain an offer to consider.

An example of an invitation to treat is when a shop displays goods on shelves with price tags. This invites customers to make an offer to buy at that price. Similarly, advertisements on social media or in newspapers invite potential buyers to submit offers for the featured products or services.

How are Offers and Invitations to Treat Different?

An offer allows the consumer to assess the offer and accept, creating a contract. On the other hand, an invitation to treat is much more informal. It allows the consumer to assess the product and provide you with the offer, which you may choose to accept. Here, the agreement is not complete until you, the seller, has confirmed. Businesses might use invitations to treat to allow the consumer to determine the value of the product.  

So, for example, your business may try to sell a vehicle through an online car auction. You believe the car has a value of £8,000, so your company makes this the reserve price. The highest offer made during the online car auction is £7,900.

In listing the car in the auction, you are not guaranteeing that you will accept the highest bid. Instead, you are making an invitation to treat to all potential bidders. In effect, you are inviting others to lodge offers to you (rather than you to them), so you can accept or reject the highest bid later on.

Similarly, consider an advertisement for a singing competition. The poster may say, ‘Can you sing? Take part in our show!’ to encourage individuals to audition. But even if you can sing beautifully, the post is not a guarantee that you will be in the show, merely that you can turn up and audition for it. It is not a true offer but rather the organiser willing to consider agreeing to future terms.

What is an Example of an Offer?

An auction may occasionally involve the seller making an offer that the buyer may immediately accept. 

For example, some companies sell excess equipment (such as monitors, old electrical equipment and printers) through online auction sites, such as eBay. eBay allows sellers to set a ‘Buy It Now’ price. In this way, your organisation could list an old printer for a ‘Buy It Now’ price of £200. This constitutes an offer. If a bid for £200 comes in, your offer to sell at £200 is now accepted. Thus, your offer would bind your company to sell that printer at £200.

Key Takeaways

A court will only enforce deals where one party clearly intends to accept a specific price for a particular item. If your company can persuade a judge that it was only inviting an offer (not making one), that court is likely to treat your comments as a mere non-binding invitation to treat. As is common within UK law, your organisation’s legal obligations depend on the exact situation and the words used.

Frequently Asked Questions

Does a party have to use the words ‘invitation to treat’ to qualify as this?

No, albeit some will use the phrase ‘offers invited’ instead. This contrasts with when an individual makes an offer with a more obvious intention.

Do some companies use ‘invitations to treat’ as a potential loophole to escape bad deals?

Sometimes, yes. If you find yourself in this situation, it is worth obtaining swift legal advice and considering whether to argue that the other party made an original offer on specific terms.

Can an invitation to treat ever become a binding offer?

No, an invitation to treat itself is not a binding offer, but it can lead to one. For example, a shop display or online listing invites customers to make an offer to purchase the item. Once the seller accepts that offer, a binding contract is created.

How does the difference between an offer and an invitation to treat affect businesses?

If you mistakenly present an invitation to treat as an offer, you may find yourself bound by terms you did not intend to enter into. For example, during a negotiation, wording matters. Saying “we accept offers” invites negotiation, whereas “we will sell for £1,000” can be interpreted as an offer. Careful use of language in communications, advertisements, or pricing ensures clarity and prevents disputes later on down the line.
