Offer and acceptance are part of how contracts are formed. There is no contract without there first being an offer.

If you accept someones offer, provided it meets the rest of the criteria for a valid contract - congratulations you now have a contract. If the any party violates it, yes this is a breach of contract.

> A written offer is not the same thing as a contract.

An offer is a precondition and component of a contract
