How to write a plumbing invoice
- Header: business name, license number, phone, email and logo. Set it once in the Word file.
- Customer and service address (they are often different for landlords and property managers).
- Invoice number, invoice date and due date. Use sequential numbers that match the estimate or work order.
- Itemized lines: service call or trip charge, labor (hours × rate or flat rate per task), each part with quantity and unit price, disposal and permit fees.
- Subtotal, sales tax (on parts where your state taxes materials), total, deposit already paid and balance due.
- Payment terms and methods: due on receipt or net 15/30, card, ACH, check, and your late fee.
- A short note of the work completed and any warranty, so the invoice doubles as a record of the job.
Example plumbing invoice line items
Showing the rate and quantity on each line answers the customer's questions before they ask, and customers pay itemized invoices faster than a single lump sum.
| Description | Qty | Rate | Amount |
|---|---|---|---|
| Service call / diagnostic | 1 | $89.00 | $89.00 |
| Labor: replace kitchen faucet and supply lines | 1.5 hr | $115.00 | $172.50 |
| Kitchen faucet, pull-down (customer approved) | 1 | $189.00 | $189.00 |
| Braided supply lines 20" | 2 | $14.00 | $28.00 |
| Disposal of old fixture | 1 | $15.00 | $15.00 |
Invoice, receipt or work order?
The invoice asks for payment. A receipt confirms payment was made (the same template works as a receipt once you mark it paid). A work order is the job ticket the plumber carries during the job; it records what was done and is what the invoice is written from.

What this invoice does for plumbers and plumbing contractors
An editable Word + PDF template built for plumbers and plumbing companies.
This template bills the job with itemized charges, discounts, tax, amount paid and balance due, payment instructions, late-fee wording, warranty, and a review request line. Open it in Word or Google Docs, replace the bracketed placeholders with your company name, logo, prices, and terms, and it's ready to use on your next job.
The invoice is the document most customers keep and the one accountants, insurers and tax preparers ask for. A clean, itemized, branded invoice gets paid faster than a handwritten one, and an invoice that references a signed estimate is rarely disputed.
It is also a reputation document. A professional invoice signals a professional business, which supports higher prices and referrals.

What is inside the template

How to use it (step by step)
- Set your master copy with header, payment methods and default terms (due on receipt, net 7 or net 14).
- Copy line items from the signed estimate; add approved extras as separate lines.
- Number invoices sequentially and record them in your bookkeeping workbook.
- Send the same day as the job; follow up with the payment reminder script if unpaid at the due date.
Common mistakes this template helps you avoid
- Sending invoices days or weeks later; payment speed tracks invoice speed.
- Omitting the due date and late-fee terms and then trying to enforce them.
- Combining several jobs on one invoice, which makes partial payment and disputes more likely.
Expert tips from the field
- Add a one-line summary of the warranty on every invoice; it reduces callbacks and reassures customers.
- Put the review request on the invoice itself. It is the moment of highest satisfaction.
- Match invoice numbers to estimate numbers so the office can find both in seconds.
Why plumbers and plumbing contractors choose this over a generic template
Generic forms are written for nobody in particular. This one was written for plumbing companies and independent plumbers: the fields, wording and clauses reflect real plumbing work such as a water heater replacement or a main-line sewer camera inspection and hydro-jet. It uses plain language customers can read, it has a header block for your logo and license number, and it matches the other Plumbing templates in the set so your intake, estimate, invoice and agreement documents look like one system.
