Contract Law · Formation of Contract

Invitation to Treat

Distinguish a legal offer from a display, quotation, advertisement, tender notice or other invitation to negotiate.

In one line

An invitation to treat invites others to make offers, while an offer is capable of immediate acceptance into a promise.

After this note, you should be able to

  • Use the control test to distinguish an offer from an invitation to treat.
  • Apply the distinction to shops, advertisements, auctions and tenders.
  • Explain why the classification matters to contract formation.

The core distinction

Ask who is making the final commitment and who retains the right to accept or reject the transaction.

Offer
The maker shows final willingness to be bound if the other person assents in the required manner.
Invitation to treat
The maker invites offers or negotiations and keeps the power to accept or reject them.
Why it matters
If the first statement is only an invitation, the other person responds with the offer. No contract exists until that offer is accepted.

Common situations

The label used by a party is not conclusive. Courts examine wording, context and commercial purpose.

Display of goods
A shelf display usually invites the customer to make an offer at the checkout. The seller can then accept or reject it.
Advertisements
Most advertisements invite customers to make offers, but a precise reward advertisement may itself be a general offer.
Auction notice
A notice that an auction will be held usually invites bids. Each bid is ordinarily an offer.
Tender notice
A request for tenders usually invites offers from bidders. Acceptance of a tender may create a contract or a standing offer, depending on its terms.
Price quotation
A statement of price commonly supplies information unless the wording also shows final willingness to sell on fixed terms.

A practical control test

Imagine that the other party says yes. Would the maker be bound immediately, or could the maker still decide whether to proceed?

If a shop display were an offer, a customer could create a contract merely by picking up an item. Treating the display as an invitation allows the seller to check price, age restrictions, stock errors and other legal conditions at the checkout.

The same reasoning explains many tenders and online listings. The platform or seller may reserve acceptance until payment, verification, dispatch or another stated event.

Work through the facts

Illustration

Facts

A website lists a laptop for Rs 4,999 because of a typing error. Its terms say that an order is accepted only when the dispatch email is sent. B places an order and receives only an automated acknowledgment.

Likely result

The listing can be treated as an invitation to treat and B's order as the offer. On these facts, the automated acknowledgment does not necessarily amount to acceptance.

What to learn

Always identify the exact event that the terms designate as acceptance. Payment or acknowledgment alone may not be conclusive.

Cases with a purpose

Landmark judgments

Learn the rule and where to use it. A case name without its legal function adds very little to an answer.

Pharmaceutical Society v. Boots Cash Chemists

Core case

(1953) 1 QB 401

Principle: Goods displayed on self-service shelves were invitations to treat. The customer made the offer at the cashier, where the sale could be supervised and accepted.

Use in an answer: Use it for shelf displays, retail transactions and the timing of acceptance.

Harvey v. Facey

Core case

(1893) AC 552

Principle: Answering a request for the lowest price did not by itself amount to an offer to sell.

Use in an answer: Use it for quotations and preliminary negotiations.

Carlill v. Carbolic Smoke Ball Co.

Core case

(1893) 1 QB 256

Principle: A precise advertisement can be an offer when it promises performance on stated conditions and shows a serious commitment.

Use in an answer: Use it as the important exception to the usual rule about advertisements.

For a 10-mark answer

Answer structure

  1. Define invitation to treat in relation to Section 2(a).
  2. State that the distinction depends on objective intention and context.
  3. Identify who made the offer and who had the final power of acceptance.
  4. Apply Boots, Harvey or Carlill according to the transaction type.
  5. Conclude by fixing the precise moment, if any, when the contract formed.

Common mistakes

  • Treating all advertisements as invitations without considering Carlill.
  • Assuming that display of a price always creates an immediate legal offer.
  • Failing to identify who has the final power to accept.
  • Ignoring the seller's stated order acceptance terms in an online problem.

Before you close the tab

Quick revision

  • Invitation to treat comes before the offer.
  • Shelf display is usually an invitation: Boots.
  • A quotation may only provide information: Harvey.
  • A definite reward advertisement may be an offer: Carlill.
  • Follow the sequence of communication to locate contract formation.

Test yourself

  1. Who makes the offer in a normal self-service shop?
  2. Why was the price statement in Harvey not an offer?
  3. What features made the advertisement in Carlill different?

Short answers

Frequently asked questions

Is a price tag an offer?

Usually it is part of an invitation to treat. The buyer makes the offer to purchase, which the seller may accept or reject.

Are all online product listings invitations to treat?

Many are, but the result depends on the wording of the listing and the seller's terms about when an order is accepted.
