What Every Plumbing Invoice Should Include
Your license number in the header
Most states expect the contractor license on invoices. Put it next to your company name and phone — not buried in the footer.
Labor broken out from parts
Separating hours and rate from materials makes tax treatment clearer and reduces disputes over a single lump sum.
Model numbers on fixtures and heaters
Record model and serial on water heaters, disposals, and major fixtures for warranty claims and future service.
Payment terms and late fee language
Due on completion or Net 30 must appear on the invoice itself, along with any late fee percentage.
Warranty for labor vs. manufacturer parts
Spell out your labor warranty separately from manufacturer coverage so callbacks do not turn into payment holdouts.
A way to pay on the spot
Card links, tap-to-pay, or financing options collapse the gap between presenting the invoice and collecting.
From Sizing Numbers to a Signed Proposal
A template is fine for a one-off. With SubcontractorHub for plumbing and plumbing CRM, the proposal your tech built on site becomes the invoice — same line items, no retyping.
Techs invoice from a tablet before they leave, customers pay by card on the spot, and financing options are available when a water heater or repipe balance is too large to pay outright.

Common Questions About Plumbing Invoicing
What should a plumbing invoice include?
A complete plumbing invoice needs your company name, license number, and contact details; the customer's name and service address; invoice number and date; itemized labor hours and rate; every part and material with quantity and unit price; applicable sales tax; total due; payment terms; and warranty language covering the work performed.
Should plumbing labor be billed hourly or flat rate?
Many residential plumbers use flat-rate pricing for common repairs because it removes clock-watching arguments and protects margin when a job runs long. Hourly or time-and-materials still fits diagnostics, commercial service agreements, and open-ended repipe work. This template supports either approach.
Do I charge sales tax on plumbing labor?
It varies by state. Many states tax parts and materials but exempt labor on real-property improvements, while others tax the full amount on repairs. Confirm the rule with your state department of revenue or accountant before setting a default tax rate.
How fast do plumbing invoices get paid?
Invoices presented and paid in the field often close same-day. Invoices emailed the evening of the job typically clear within a week. Invoices sent days later routinely stretch past 30 days — the main source of aging receivables for service plumbers.
What payment terms should plumbers use?
For residential service and repair, payment due on completion is standard. For larger installs, a deposit at signing plus balance at completion is common. Commercial accounts often use Net 30 with a late-fee clause printed on the invoice.
Is this plumbing invoice template free?
Yes. Build your invoice on this page at no cost and with no signup. Nothing you type is stored or transmitted — totals calculate in your browser. Use print to save a PDF or hard copy.
