A common request
"I already bought the part online, can you just install it?" Every service company hears this. The customer thinks they are saving money. The contractor sees risk: the wrong part, a poor-quality part, a second trip and a warranty question nobody can answer. Having a clear policy keeps the conversation simple.
The real risks
- The part is wrong, incomplete or damaged, and the visit is wasted.
- The part fails and the customer blames your work.
- You lose the margin on materials that helps pay for overhead.
- Your warranty becomes unclear.

Three policies that work
Decline politely: you only install parts you supply, so you can stand behind the job. Accept with conditions: labor only, at a higher labor rate, no warranty on the part. Accept case by case: for simple items like fixtures or faucets the customer picked for style.
Charge for labor properly
If you install customer-supplied parts, your labor price must stand on its own. Many companies use a higher rate or a minimum charge for these jobs, because there is no material margin to support the visit.
Put the warranty in writing
Write on the estimate and invoice that the warranty covers your workmanship only, not the part. If the part fails, a new visit is billable. Clear writing prevents arguments months later.
What to say
"We can install it, but since we didn't supply the part, we can only warranty our labor. If the part is wrong or fails, a return visit would be charged. Or we can supply a part we know and warranty the whole job. Which do you prefer?" Many customers choose the full warranty.
Be consistent
Train everyone who answers the phone to explain the same policy. Exceptions decided in the field create confusion and make the next customer expect the same.
When it makes sense to accept
Some items really are a matter of taste: a light fixture, a faucet, a ceiling fan or tile the customer picked out at a showroom. Here, accepting the customer's choice builds goodwill. Ask for the model number before the visit, confirm it is complete and compatible, and keep the labor-only terms. Saying yes in the right cases is good service, as long as the rules are written down.
