Free Plumbing & HVAC Invoice Template
A plumbing invoice covers the billed line items, totals, and the payment terms, including a 14-day due date and what happens on late payment.
A bathroom or boiler job can start with one clear fix and then turn messy once the wall opens up, and nobody wants to be left without hot water while trades bounce responsibility around. This plumbing invoice goes to the customer as the billing record for the work, so the price and the due date don’t end up as a back-and-forth after the fact.
The invoice puts the numbers up front in Line items, then rolls everything into a totals block before the customer hits the terms. Headings use Zilla Slab with Roboto for the body text, and the page leans on a deep plum with an ink blue accent, so the whole thing reads like a piece of work documentation rather than a marketing page. The payment section says the bill is due in 14 days, and it also names what you’ll do if payment runs late, including pausing work after a warning.
- Line items Replace the five placeholder lines with your own work and prices before sending.
- Il pagamento è dovuto entro 14 Carries the totals and states the 14-day due date, plus what happens if payment is late.
- Grazie, felice di restituirti il bagno pronto e funzionante Closes the invoice with a short sign-off you can keep or swap.
- Totals Shows the amount due based on the line items you enter.

Questions about this invoice
What should a plumbing invoice include?
A plumbing invoice usually includes the billed line items, the totals, and the payment terms. This one also states a 14-day due date and explains what happens if payment is late.
How do I write payment terms on a plumbing invoice?
Payment terms need a due date and a clear late-payment consequence that matches how you actually work. The template includes 14-day terms and mentions warning the client and pausing work until payment arrives.
Should a plumbing invoice list each task as a separate line item?
A line-item list helps the customer understand what they’re paying for and reduces disputes. The template gives you five placeholder lines, and you replace them with your own tasks and prices.
Can a plumbing invoice be paid online?
An invoice can be paid online if a payment method is connected before you send it. The template supports that option, but the payment method still needs to be set up.
What do I do if a customer pays a plumbing invoice late?
A late-payment clause should say when payment is due and what you’ll do if the date passes. The included wording says you’ll flag updated timelines and may pause work after giving notice.
How do I invoice for unexpected issues found after opening a wall?
An invoice can only bill what you decide to charge for, so the line items need to match the actual work and materials. When scope changes mid-job, you update the line items and totals to reflect the new reality before sending.
