How to invoice as a plumber in under a minute
Fill in the form, watch the live preview, and download or save. Here is the full walkthrough.
- 01Add your business name, address, phone and plumbing licence number (required on invoices in most places; check your local rules), then the customer’s name and the service address.
- 02Fill in "Service call and diagnosis" at your call-out rate with what you found in the description, for example "No hot water: failed heating element on 50-gallon electric water heater".
- 03Fill in "Labor (hours)" with the hours and rate, or set quantity 1 at your flat rate for the task if you price by the job. Say what was done: "Replaced upper and lower elements and thermostats, tested".
- 04List "Parts and fixtures" with the part names and quantities, and any permit for a water heater or re-pipe at cost. Add "Emergency or after-hours fee" only if the call was outside your hours; delete it otherwise.
- 05Set tax per line (parts are often taxable where labor is not; check your local rules), upload your logo, and click Download free PDF or Create account & save to take payment by card on site.
The notes start with "Payment due on completion. Labor warranted for 90 days; parts carry the manufacturer warranty. Service call fee applies even if no repair is authorized." Edit that sentence if your terms differ. Get the repair approved before you do it, in writing if you can (a text message is enough), and take a before and after photo; the two together end almost every dispute.
What should a plumbing invoice include?
A plumbing invoice is written at the kitchen table with the customer watching, so it has to be clear the first time. Include the following.
- Your business name, address, phone and plumbing licence number
- The customer’s name and the service address, plus the date and time of the visit
- A unique invoice number, the invoice date and the due date (on completion in the notes)
- The service call and diagnosis as its own line, with what was found written in the description
- Labor as hours at your rate or a flat rate per task, with a plain-language description of the work done
- Parts and fixtures by name and quantity, with any manufacturer warranty noted
- Permit and inspection fees at cost where the job required one (water heaters, re-pipes, gas lines)
- The emergency or after-hours fee only when it applies, and the estimate or approval reference
- Tax per line where parts are taxable and labor is not (check your local rules)
- Your labor warranty period, payment terms and how to pay, with a card or payment link for on-site payment
Taxes, VAT, GST, and multiple currencies
You can mark each line item taxable or not and set the rate, so a single invoice can mix taxed and untaxed items. This per-item control is something many simple tools cannot do, where one document is limited to one tax rate.
Documents render in 12 currencies with locale-correct formatting: USD, EUR, GBP, CAD, AUD, JPY, INR, PKR, MXN, NZD, ZAR, and SGD. That covers VAT in the EU and UK, GST in India, Australia and Canada, and US sales tax. Need detailed tax handling across your whole workflow? See the tax feature.

Plumbing lines pre-listed
"Service call and diagnosis", "Labor (hours)", "Parts and fixtures" and "Emergency or after-hours fee" are already on the invoice with blank amounts, and the notes carry due-on-completion, the 90-day labor warranty and the service-call-applies wording.
Frequently asked questions
What should a plumbing invoice include?
Your licence number and contact details, the customer and service address with the visit date, invoice number and dates, the service call and diagnosis as a line with the finding described, labor as hours or a flat rate with the work described, parts by name and quantity, permit fees at cost, the after-hours fee only if it applies, tax per line, and the labor warranty with payment terms. The four pre-listed lines are the shape of nearly every service ticket.
Should the service call fee be separate from labor?
Yes, and the pre-filled notes say why: "Payment due on completion. Labor warranted for 90 days; parts carry the manufacturer warranty. Service call fee applies even if no repair is authorized." The call fee pays for getting there and finding the fault; the labor line pays for fixing it. Keeping them apart means that when the customer declines the repair you still have a line to charge, and when they accept it they can see the diagnosis was not double-billed. Many plumbers credit the call fee against the repair if it goes ahead; if you do, show the credit as a discount rather than deleting the line.
How should I bill parts and add the warranty?
List each part by name and quantity ("Moen 1225 cartridge, 1"), at your selling price including any markup; customers accept a markup on parts far more readily than a surprise, so do not hide it inside labor. Note that parts carry the manufacturer warranty and that your labor is warranted for the period in the notes (90 days by default; a year is common on installations). Keep supplier receipts for your own records and attach them only if the customer asks or the contract requires it.
When should a plumber send the invoice, and what is the most common mistake?
On completion, on site, with payment taken before you leave: the notes say payment is due on completion, and a card reader or payment link makes that practical. Property managers and commercial accounts are the exception; bill them with Net 15 or Net 30 and their work order number on the invoice. The most common plumbing invoicing mistake is doing extra work discovered mid-job without getting it approved first, then adding it to the bill; the second is leaving without payment and chasing a small invoice for weeks.
Is my client data safe?
Yes. Everything you type stays in your browser. Nothing is uploaded or stored on our servers unless you create an account and save the document yourself. See our privacy policy for details.
What currencies are supported?
USD, EUR, GBP, CAD, AUD, JPY, INR, PKR, MXN, NZD, ZAR, and SGD, each formatted correctly for its locale.
Do I need to install anything?
No. Everything runs in your browser. There is nothing to download or install.
What happens when I create an account?
Your invoice is carried straight into your new Invoice My Clients account. Your invoice arrives ready, PDF generated, so you can send it and get paid online. From there you can edit it, send it, track payment, and get paid online.
Does it remember my business details?
Yes. Your own business details, logo, currency, and payment information are saved on your device (in your browser, never on our servers) so you do not re-enter them next time, and your invoice number auto-increments from the last one you used. Client details, line items, and amounts are never saved. You can clear everything any time with the "Clear saved details" link above the form.
Is there a Spanish version?
Yes. The same invoice generator is available in Spanish, with the document, the labels and the PDF in Spanish, at the "Español" link in the header.
