How to price revisions
Revisions need a definition. A correction within the agreed direction is not the same as a new concept, feature or source-material change.
1. Collect assumptions
Set the number of rounds, feedback process and client response time. Add a realistic time buffer for every round.
2. Check price and risk
After the allowance is used, charge an extra-work rate or re-price the changed scope.
3. Document working rules
Translate the calculated result into a simple proposal: what the client receives, by when, how many changes are included and what happens when scope changes. The price then relates to a defined commitment.
Calculate cost and the floor first, then choose a price that fits scope and outcome value.
