How to handle customer-supplied materials
Customers sometimes buy their own materials. You can say yes, but you need clear terms on responsibility and fit.
- Decide your policy. Accept, accept with conditions, or decline.
- Put it in writing. Note in the quote who supplies what.
- Inspect on arrival. Check for damage and missing parts before you start.
- Explain warranty limits. Your workmanship warranty may not cover the part itself.
- Charge fairly for the extra risk. Returns, delays and mismatches cost time.
Common questions
Do I have to install customer parts?
