Free plumbing invoice template with a working editor, live totals and PDF, Word or Excel downloads.

Before you send

Pricing, pitfalls and proof

  • How it is pricedBill the appliance, parts, labour and commissioning separately.

  • Keep as evidenceKeep the commissioning record, the parts invoices and the warranty terms.

Questions about this template

Should the boiler model be on the invoice?

Yes. It matters for the manufacturer's warranty and for future servicing.

How do I bill an emergency call-out?

As a line with the out-of-hours rate stated. It should be visible, not folded into labour.

Can I invoice parts I supplied at cost plus?

Yes, but state the arrangement. A single parts line is fine when the markup policy is agreed.

What about a system flush?

List it separately; many warranties require it and the client should see why it was needed.
