Entire agreement / integration
Also known as: Merger clause, Integration clause
A clause stating that the written contract contains the complete agreement and supersedes prior discussions.
What it is
An entire agreement clause (sometimes called an integration or merger clause) confirms that the signed document is the whole deal. It tells a future reader — and a future judge — that prior drafts, side emails, slide decks, and conversations have been replaced by what is written on the page. Stronger versions also include a non-reliance statement, in which each party acknowledges that it has not relied on any representations outside the contract when deciding to sign.
Why it matters
Without this clause, a party can point to an off-the-cuff email or a slide deck from a sales call and argue that it forms part of the agreement, or that it was the basis on which they signed. That can pull the contract in unexpected directions, even if the written terms say something else. The integration clause is a lightweight but important piece of discipline: it forces everything important into the body of the document and reduces the risk of "but you told me…" arguments after the fact. It does not, however, cure outright fraud or override mandatory statutory rights.
Typical language
An example of how this clause often reads — illustrative only, not a template:
This Agreement, together with its schedules, constitutes the entire agreement between the parties with respect to its subject matter and supersedes all prior discussions, negotiations, representations, and agreements, whether written or oral. Each party acknowledges that in entering into this Agreement it has not relied on any statement, representation, or warranty other than those expressly set out in this Agreement.
Common pitfalls
- Assuming the clause overrides fraud claims — it generally does not.
- No non-reliance language, leaving room for pre-contract representations to resurface later.
- Forgetting to include schedules, statements of work, or order forms in the "entire agreement" so they are accidentally excluded.
- Boilerplate that conflicts with an amendment or variation clause elsewhere in the contract.
- Treating the clause as magic: it cannot fix contradictions inside the contract itself, only competition from outside it.
