Free Plumbing Invoice Template
A clean, professional invoice template for plumbing businesses — free to download and use, no email required. The Excel version calculates line amounts, tax, and the total automatically; the Word version is a fill-in you can print.
A plumbing invoice should be issued the day the work wraps and clearly separate parts from labour, with any added work — the shutoff that had to be replaced, the wall that had to be opened — itemized. Small plumbing invoices age badly, so a clean, same-day bill gets paid faster.
Free for any use. No sign-up, no email gate.
What a good plumbing invoice includes
- ✓Your business name and contact details — and the client's.
- ✓An invoice number, issue date, and a clear due date.
- ✓Line items that match what was quoted and what was actually done.
- ✓Subtotal, tax (at your local rate), and the balance due.
- ✓How to pay you: methods you accept and any late-payment terms.
- ✓Invoice the same day the work is done; small jobs are easiest to collect while the work is fresh.
- ✓Separate parts from labour and list fixtures and valves installed for the customer's records and warranty.
- ✓Bill added work found on site — a failed shutoff, corroded fittings, wall access — as its own line with a short note.
- ✓Reference the service call or work-order number so the payment reconciles cleanly.
- ✓State any parts and labour warranty, deposit applied, payment due date, and accepted methods.

Common questions
Is this template really free?
Yes — download it and use it for any business. No email, no sign-up, no watermark beyond a one-line credit you can delete.
What's the difference between the Excel and Word versions?
The Excel version calculates line amounts, tax, and the total automatically from what you type — enter your tax rate once and the math is done. The Word version is a clean fill-in you can print or edit.
Can I edit the template?
Completely. Add your logo, change labels, add rows, adjust the terms — it's yours to adapt.
When the template becomes the bottleneck
Templates work until you're retyping the same client, the same lines, and the same totals every week. Stairkey turns the job itself into the invoice — quoted, approved, and billed from one record. See how it fits plumbing.
