Describe the complete request
Include the work around the obvious task: preparation, review, testing, deployment and handoff where applicable. Identify what can be reused and which dependencies are still open. Do not quote an undefined bundle of future requests.
Check the delivery estimate
The free calculator shows how extra hours affect an entered fee and hourly delivery cost. Its fee estimate preserves the original delivery-margin percentage under its stated assumptions. It does not account for different cost rates, taxes or omitted overhead automatically.
Choose the commercial proposal
Review the scope, risk, timing and relationship before setting the final selling price. State the amount plainly and describe what the client receives. If there are options, make them separate decisions rather than implying that everything is included.
Keep status and evidence separate
Save the proposed change before sharing it. A client response can be reviewed and applied when it still matches the quote. Payment, a formal signature and the internal change status remain different records; do not use one as proof of the others.
