Who has more leverage in contract negotiations with an agency?
The firm, especially in the days after the agency has been told it has won, which is the moment to insist the contract accommodates the attached response.

Why your contract should have the RFP response stapled to it
The agency's own RFP response, attached as a contractual document. The response answers dozens of questions under competitive pressure, naming the team, price, timeline, warranty and integrations, while the agency's statement of work is usually shorter, vaguer and worded in its favour. Word the contract so the RFP response takes precedence on scope. Warranty terms then become enforceable, the budget breakdown becomes the invoice structure, and a disputed integration comes with a page reference.
Why attach the RFP response to the contract?
Because otherwise the commitments get swapped for vaguer ones. The build slips, the agency comes back to renegotiate scope, and the marketing lead finds a four-page statement of work that says "deliver a website". In the RFP response the agency answered forty-one questions within word limits, described its method, named the team, quoted the price, committed to a timeline and set out warranty terms, the CMS and the integrations. Sign the agency's own statement of work instead and you swap thirty pages of specific commitments made under competition for four pages drafted under no pressure. Attach the response, and word the contract so any conflict is resolved in favour of the more specific document, with the RFP response taking precedence on scope. The agency wrote the words and can defend them.
What does attaching the response give the firm?
Terms it can hold the agency to when the build gets difficult. Warranty and service levels become enforceable: if the response said critical bugs are fixed within eight hours, major bugs within sixteen and the post-launch warranty runs ninety days, that is what the agency owes. The budget breakdown becomes the invoice structure: if discovery was itemised at £10k, design at £20k and development at £50k, overruns show on the line where they happen, and moving money between lines needs agreement. And the scope is documented: if the response promised integration with MS Dynamics, Salesforce, MailChimp, Passle and Demandbase, a later claim that one of them is out of scope meets a page reference.
How do agencies push back, and how do you answer?
In three ways. The response was "indicative" or "subject to discovery": attach it anyway, with a clause allowing specific variations by written consent during discovery, so the response is the default. The response is out of date by signing: accept an updated response during negotiation and attach that instead, since the point is an attached document of commitments. The contract template "does not work that way": then the question is whose template wins, and the firm has more leverage than it thinks in the days after the agency learns it has won.
How does in-house legal usually react?
Well, because the approach mirrors how a law firm contracts with its own clients: specific scope, specific deliverables, specific terms, and anything else by exception with consent. The argument that does not work is wanting the agency to be flexible, since flexibility is what causes scope creep; scope changes belong in a defined process. Attaching the response costs a few hours of legal review and a sharper negotiation. Not attaching it costs change orders, scope arguments and partner meetings about paying again for what the firm thought it had bought.

Questions people ask
Should an agency contract leave room for flexibility?
Scope changes should go through a defined process with written consent. Leaving scope vague for the sake of flexibility is what causes scope creep.
