Managing variations without losing money or goodwill
Unpriced changes are a silent profit killer. How to handle variations professionally.
The silent profit leak
Variations — changes to the agreed scope — are normal on almost every build. The problem is doing the extra work first and pricing it later, or never. Unpriced variations quietly erode margin and breed disputes at the end of the job.
Document before you build
Good practice is simple but disciplined: capture the change in writing, price it, get the client's sign-off, and only then proceed. It protects your margin and gives the client certainty about cost.
Protect the relationship
Handled well, variations actually build trust — the client sees a professional who is upfront about cost rather than one who ambushes them with a surprise bill. Handled badly, they're the number-one source of end-of-job conflict.
Make it routine
A standard variation form and a no-exceptions rule ('we price changes before we do them') keeps everyone honest and your profit intact.
