How it works
We add review and testing overhead
A 25% overhead is added automatically to cover the review and testing work that raw dev hours miss.
Get a price at your target margin
The raw cost is grossed up to your target margin, giving the number to actually quote the client.

Frequently asked questions
Why add 25% overhead automatically?
Change requests are frequently quoted using only raw development hours, which consistently underprices the work — review, testing, and regression checking on existing code add real time that's easy to forget.
Should every change request go through this formal pricing?
For anything beyond a trivial fix, yes — informal "sure, I'll just add that" agreements are the most common source of scope creep and unpaid work on fixed-price engagements.
What if the client pushes back on the price?
Show the hour breakdown, not just the final number — transparency about dev, review, and testing hours makes the price easier to justify than a single opaque figure.
