How to reply to a client asking for work outside the agreed scope
Updated November 12, 2026
Reply within a day, and do not quietly say yes. Thank them for the idea, name what the agreement covers, and offer a choice: add the work for an extra fee and date, swap it for something already planned, or save it for a later phase. Keep the tone friendly and the facts clear.
- Reply
- Within 1 day. Slow answers let the client assume the extra work is included. A quick, friendly boundary now avoids a bigger argument later.
What your reply should say
- Acknowledge the request as reasonable, so it does not feel like a refusal.
- Point to what the agreement or brief covers, using its exact wording if you can.
- Offer options with the cost or time impact for each one.
- Ask them to choose, and say work starts once they confirm in writing.

1Add it for a fee
You can do the extra work and it should be paid.
Hi [Name], Good idea. That is outside what we agreed in the [contract/proposal], which covers [scope]. I can add it for [price], and it would move the delivery date to [date]. If you would like that, reply "approved" and I will update the plan. If not, we keep everything as agreed and stay on schedule. Best, [Your name]
2Swap for something
The budget and timeline are fixed, so something has to give.
Hi [Name], Thanks for the idea. We could do that within the current budget if we drop something of similar size. The closest match is [item already in scope]. Which would you prefer: keep the original plan, or swap in [new request]? Once you choose, I will confirm the updated scope in writing and carry on. Best, [Your name]
3Save for phase two
The request is good, but it would put the current deadline at risk.
Hi [Name], I like this idea, and I think it would help [their goal]. If I add it now, I would put the [date] deadline at risk. My suggestion is to finish the current scope first, then plan this as a second phase. I can send a short quote for it by [date]. Does that work for you? Best, [Your name]
Already late? Send this instead
For when you are several days, after already starting the work late or more. Own the delay in one line, then do the job.
Hi [Name], Sorry for not replying sooner about [request]. I should have raised this before I started on it. That work is outside the agreed scope. I have done [what you did] so far. I can finish it for [price], or stop here and return to the original plan. Please let me know which you prefer so I can plan the next few days. [Your name]
Mistakes to avoid
- Saying "sure, no problem" and planning to bring up the cost later.
- Treating the request as an attack. Most clients do not realize it is extra.
- Quoting a fee without saying how the deadline changes.
- Starting the extra work before they approve the price in writing.
Questions people ask
How do I know if something is scope creep?
Compare it with your signed agreement or written brief. If a task, revision or feature is not listed, or goes past the number of rounds you agreed on, it is extra. When the wording is vague, say how you read it and ask if they agree.
What if the client says it should be included?
Stay calm and go back to the document. Show what it lists. If the wording really is unclear, you can decide to include it once and clarify the terms for the future. For real disputes, check your contract or ask a lawyer before you push back.
