An extra-work fee is not a punishment for asking. It is the price of a changed production decision. The cleanest conversation starts with the approved baseline and ends with an explicit client choice.

The practical pricing formula
Production: hands-on delivery time at your required commercial rate
Coordination: briefing, communication, file handling, review, and approval
External costs: specialists, licenses, assets, travel, or other direct expenses
Schedule impact: rush pressure, displaced work, or a changed delivery sequence
Change fee: the complete cost above, priced with the margin your business requires
The calculation is an internal decision tool. The client-facing quote can remain a simple fixed amount tied to the added output and revised date.
Five steps from request to approved fee
01
Return to the approved baseline
Name the deliverable, revision limit, assumption, format, audience, or date that the current plan already covers. Pricing is easier when both sides can see what changed.
02
Describe the delta
Write one neutral sentence explaining the added output or changed condition. Avoid arguing about whether the request is reasonable; identify the new decision instead.
03
Calculate the full impact
Include production time, coordination, review, specialist costs, schedule pressure, and the work that may need to move. The visible edit is rarely the entire cost.
04
Choose the cleanest commercial option
Use a fixed change fee when the work is predictable, a time-based allowance when it is uncertain, or a named scope trade when the budget must stay fixed.
05
Get approval before scheduling
State the fee and timing impact together, give the client a clear choice, and keep the request outside production until the selected option is approved in writing.
Illustrative example
A client requests an additional landing page after the original page set is approved. You estimate six hours of production and 1.5 hours of coordination. At an internal commercial target of $100 per hour, the delivery impact is $750. A $100 specialist cost brings the fixed change fee to $850, with the milestone moving by two working days.
Keep the estimate and the quote separate
Your internal calculation can contain rates, buffers, and margin. The client needs the added output, fixed fee, timing impact, and approval step—not every line of your costing model.
A calm pricing message
I compared this request with the approved scope. Adding [output] will be [fee] and will move [milestone] from [current date] to [new date]. If you would rather keep the current budget, we can trade [included item] or schedule the addition as a later phase. Please confirm the option you would like before I place the extra work in production.
Connect the fee to the project record
Start with a clear scope baseline, use the out-of-scope email templates to present the choice, and record the approved change with the change request template.
Frequently asked questions
How much should I charge for out-of-scope work?
Base the fee on the full delivery impact rather than a universal percentage. Include production, coordination, review, external costs, schedule pressure, and the margin required for the work to be commercially sensible.
Should I use an hourly rate or a fixed change fee?
Use a fixed change fee when the output and effort are clear. Use a time-based allowance with a cap or checkpoint when the request still contains material unknowns.
What if the client says the request is only a small change?
Acknowledge that the visible change may be small, then explain the complete impact: research, source-file updates, exports, testing, stakeholder review, dependencies, or schedule movement.
What if the client will not approve the additional fee?
Offer a named trade, move the request to a later phase, or continue with the original plan. Do not begin the added work while the commercial decision is unresolved.
