Plumber invoice NZ

What goes on a plumber invoice.

Whether you're using a plumber invoice template NZ-wide or building one from scratch, here's what a valid plumbing invoice needs to include.

What to include

A proper plumbing invoice — whether it's a callout, an install, or a full plumbing contract — should always show your labour, parts, and the paperwork IRD expects to see.

Labour (hours × rate)
Parts & materials used
Call-out fee
GST number & GST breakdown
Job description & site address
Invoice number & date

GST requirements for plumbing contractors

If you're GST-registered (required once you cross $60,000 in a year), every plumbing invoice must show your GST number, the GST rate charged (15%), and the total both GST-exclusive and GST-inclusive. TradieNotes calculates and itemises this automatically — including the option to issue non-GST invoices if you're not yet registered.

Common plumber invoice line items

Most plumbers bill a mix of the same few line items on every job — TradieNotes' AI recognises each of these from your notes or voice recording.

Hourly labour rate
Parts & materials (pipe, fittings, valves)
Travel / call-out charge
After-hours rate
Plumber FAQ

Questions, answered.

Can I include call-out fees and travel?
Yes. Just note the call-out fee or after-hours rate in your scribble or speak it aloud — the AI will extract it as a separate labour line item.
Does it handle gasfitting invoices?
Not required, but if you write it in your notes it will appear on the invoice. Useful for commercial and insurance jobs.
What about PGDB compliance references?
TradieNotes works for any trade. Gas items, fittings, and compliance notes all extract the same way.
Are the invoices GST and IRD compliant?
Yes — every invoice includes your GST number, business name, itemised labour and materials, and meets NZ IRD requirements.
Do I need an account?
No account needed. Create one free to save your invoice history, or just snap and pay $1.
