Plumbing invoice template for service calls, repairs and installs
A plumbing invoice has to survive a conversation at the kitchen sink. The customer wants to know what the trip charge covered, what the part cost, how long the labor took, and what happens if the same fitting leaks next month. This page shows how to structure a plumbing invoice around those questions, and how to produce it in Invoice Chief before you leave the property.
What belongs on a plumbing invoice
Plumbing work is usually billed as a stack of distinct events rather than one flat number. Keeping them on separate lines is what stops the callback and the discount request:
- Service call / trip charge. Its own line, with the reason it applied — standard hours, after hours, weekend, second visit.
- Diagnostic time. Camera inspection, leak location, pressure test or drain tracing, billed separately from the repair that follows.
- Fixtures and equipment. Water heater, toilet, faucet, disposal, pressure-reducing valve — named specifically, not as “parts”.
- Rough materials. Copper, PEX, PVC, fittings, valves, solder, flex connectors and sealants, grouped as a materials line.
- Labor by hours and rate. Separate rows when the visit mixed helper time with journeyman time.
- The service address. Where the pipe actually is, which is frequently not where the bill goes.
- Permit and inspection costs when the job was permitted — for example a water heater changeout or a repipe. Bill only what your jurisdiction actually charged you, and say which permit it was.
- Payment terms and warranty wording — the terms you offer on labor, and whatever the manufacturer covers on the fixture.
Example: water heater replacement invoice
This is an illustrative example, not a real customer invoice. Amounts are placeholders — use your own rates and local pricing.
| Description | Qty | Rate | Amount |
|---|---|---|---|
| Service call — after-hours dispatch, no hot water reported | 1 | 125.00 | 125.00 |
| Diagnostic — gas water heater, thermocouple and pilot assembly tested | 0.5 hr | 110.00 | 55.00 |
| 40 gal atmospheric vent gas water heater, supplied and installed | 1 | 845.00 | 845.00 |
| Water heater installation labor — drain, disconnect, set, reconnect gas and water | 3 hr | 110.00 | 330.00 |
| Materials — flex connectors, gas sediment trap, T&P discharge pipe, dielectric unions | 1 | 96.40 | 96.40 |
| Haul-away and disposal of old unit | 1 | 45.00 | 45.00 |
| Subtotal | 1,496.40 | ||
Example customer message
“Old unit was leaking at the tank seam and was not repairable. New heater set, gas and water reconnected, T&P discharge run to within 6″ of the floor, unit fired and tested at temperature. Old heater removed from the property.”
Example notes and terms
“Balance due on receipt. Labor on this installation carries our 1-year workmanship warranty; the tank and parts are covered by the manufacturer's written warranty supplied with the unit. Warranty does not cover damage from water quality, pressure above code limit, or work performed by others.” Adjust this to the terms you actually offer.
Building this invoice in Invoice Chief
Quote the changeout first
Build the heater, labor and materials as an estimate in the driveway. The customer can sign it on your phone or from their own device, and the signed version is preserved exactly as agreed — useful when a tank swap turns into a code-driven addition later.
Record the service address
Bill-to details come from the customer record; when the pipe is somewhere else — a rental, a second property, a management company's tenant — add a separate job site address and it prints alongside the bill-to block.
Keep the lines granular
Each line carries a description, quantity and rate, so trip charge, diagnostic time, the heater, install labor and materials all stay visible. Long invoices paginate cleanly in the PDF instead of being cut off.
Send it before you pull off the curb
Share the finished invoice by email, SMS or WhatsApp, or download the PDF. Record a deposit or partial payment and the balance due updates on the document.
If you run a service company and a separate remodel or new-construction entity, each can be its own business in the same account, with its own logo, currency and invoice numbering.
