For a fixed price, define the result, assumptions, revisions, and extras. For hourly work, state the rate, minimum block, time reporting, spending cap, and approval point. A hybrid approach can set a diagnostic fee and quote the repair separately.
Fixed pricing suits a well-defined, repeatable scope because the customer knows the agreed total; it puts more estimating risk on you. Hourly pricing can suit uncertain work but requires clear time records and an expected range. Explain which costs sit outside either method and how changes are approved. Choose based on the work's uncertainty and both parties' ability to verify progress.
For either method, identify what changes the price, such as extra materials, waiting, or scope variation. Give the customer a way to review progress before costs accumulate. Do not present hourly work as unlimited or a fixed quote as covering unknown conditions.
Choose the method that makes the risk understandable to both sides. Explain how you quote on your KobStore page; create one and let customers know which details to provide.
