Plumbing invoice template

An invoice that gets paid without a phone call has three properties: the customer can see what they bought, the tax treatment is obvious, and the terms are on the page. This one is editable in the browser and prints clean — no account, nothing sent anywhere.

Why labour and material tax separately

States split on whether installed labour is taxable, and several tax it only when the work is a repair rather than a capital improvement. The toggle exists because getting it wrong in either direction is expensive: charge tax you should not and you owe the customer; skip tax you should have charged and you owe the state, with interest.

Whatever your state does, say it on the face of the invoice. "Tax at 7.25% on materials" ends the argument before it starts.

This is not tax advice

Sales-tax treatment of contracting labour is set by your state and sometimes by your county. Confirm it with your accountant or your state revenue department, not with a template.

The three lines that stop callbacks

Name the diagnostic separately, even when you waive it on acceptance — the customer needs to see that finding the problem was work. Show labour as hours times a rate rather than a lump, because a lump invites the question and hours answer it. And give every part its own line with a description a person can recognise, not a supplier SKU.

Put the licence number in the header. In most jurisdictions it is required on the document, and where it is not, it still reads as a shop that expects to be checked.

Printing

Print gives you the invoice and nothing else — the navigation, the footer, this article and every button disappear. Print to PDF for the customer copy; the layout is built for portrait Letter and A4 without adjustment.
