- Offer: An expression of willingness to enter into a contract on specific terms, made by the offeror to an offeree.

- Proposal: Similar to an offer, it suggests terms and conditions for a potential agreement. It's often synonymous with an offer but can be broader.

- Tender: This is a bid or offer to perform work at a specified price, often used in procurement or construction contexts. It broadly matches an "offer of performance."

- Acceptance: Agreement to the terms of an offer, thereby creating a binding contract.
