Free Plumbing Invoice Template
Plumbing customers rarely question your work — they question the bill. An invoice that clearly separates the service call fee, labor hours, and every part you installed answers those questions before they're asked, and gets you paid without the phone call.
This free plumbing invoice template is built for service work: emergency calls, repairs, installs, and remodels. Itemize parts with quantities and unit prices, bill labor by the hour or as a flat rate, add your license number in the notes, and download a PDF on the spot.

Separate parts from labor — always
Customers accept part costs at near-retail prices and accept labor rates as your expertise; what they dispute is a single mystery number. Separate lines defuse the dispute and simplify your bookkeeping.
Bill the service call fee up front
State the diagnostic or trip fee when booking and put it at the top of the invoice as its own line. If the customer proceeds with the repair, many plumbers credit it toward the job — note that credit as a discount line.
Note the warranty on every invoice
"Labor warrantied for 90 days; parts per manufacturer warranty" in the notes field protects both sides, and a written warranty is one of the strongest signals that you stand behind your work.
Frequently asked questions
How do plumbers usually structure an invoice?
Service call fee first, then labor (hourly or flat), then parts with quantities and unit prices, then tax. This template follows that structure — customers can see exactly where the total comes from.
Should I charge flat rate or time and materials?
Flat rate works for predictable jobs (water heater swap, toilet install) and customers like the certainty. Time and materials is safer for diagnostics and old-house surprises. The template supports both on the same invoice.
Can I collect payment at the job site?
Yes — with the free Easy Invoice mobile app you can send this invoice with a payment link, or take a card or contactless payment on your phone before you leave the driveway.
Do I need to include my license number?
Many states and provinces require a contractor or plumbing license number on invoices. Add it next to your business name or in the notes — this template has space for both.
