Pro tips for plumbings

Payment terms

Collect payment on completion for residential calls; for new-construction or commercial work, bill on a progress schedule with a deposit.

Tax

Plumbing parts are typically taxable while repair labor may be exempt depending on your state — keep parts and labor on separate lines.

Plumbing invoice FAQ

What should a plumbing invoice include?

A service-call/trip charge, itemized labor, parts with quantities, any emergency premium, permit fees, and your plumbing license number.

Should I charge a trip or service-call fee?

Yes — a standard trip charge covers your time and travel to diagnose the problem, and is usually applied whether or not the customer proceeds with the repair.

How do I bill emergency or after-hours work?

Add an emergency or after-hours premium as a separate line, often 1.5× to 2× your normal labor rate. Disclose it before the work so there are no surprises.

Is sales tax charged on plumbing work?

In most states parts are taxable and labor may or may not be. Separating parts and labor lets you apply tax correctly per your state's rules.
