How do I charge for extra work a client requests?
Confirm that the request is outside the agreed scope, estimate the added effort, and send the price and schedule impact for approval before doing the work.
Check whether it is an addition or a correction
Compare the request with the accepted brief and revision allowance. Fixing a missed agreed requirement is different from adding a new deliverable. Do not charge simply because a client has asked a question; first resolve the classification together.
Show what the extra price buys
A useful change proposal names the new outcome, assumptions, included revisions and timing. Use a fixed price or hourly estimate that fits the engagement. If the effort is uncertain, define a review point rather than implying an unlimited commitment.
- Name the existing project and accepted scope version.
- Describe the added deliverable and what remains unchanged.
- State the price, currency and timeline impact.
- Get an explicit decision from the person authorized to approve cost.
Keep the original financial record intact
In a fictional project, a $150 addition to a $1,250 issued invoice should be easy to distinguish from the original $1,250. Keep the accepted addition and the related new billing record linked. Choose the appropriate adjustment document for your circumstances; ask an accountant about jurisdiction-specific requirements.
Follow the decision into delivery
Moolamochi creates a supplementary draft for financial review after a positive scope change is approved against issued work. Approval is not payment, and the new work still needs to be delivered. You can inspect the example while new account access is waitlist-only.
