What a plumber invoice should show
A plumbing invoice is easier to pay when it reads like a short job report: the problem, what you did and the parts. That's also what an insurer or landlord will ask to see.
Line-item wording you can borrow
Specific descriptions get paid faster than "labour and materials". Examples for plumbers:
- Attend blocked sewer, clear with electric eel, CCTV inspection of line
- Replace leaking kitchen mixer tap (customer-chosen model)
- Supply and install 250 L electric hot water system, remove old unit
- Replace cistern inlet valve and washer, ensuite toilet
- Locate and repair burst water pipe under front lawn
- Install isolation valves to vanity basin
- Gas leak test and certificate (if applicable)
- Disposal of old hot water unit
If you're registered for GST, a tax invoice for a sale under $1,000 must show: that it's a tax invoice, your identity and ABN, the issue date, a description with quantity and price, the GST (or "Total price includes GST" if GST is exactly 1/11 of the total) and how much of each sale is taxable. From $1,000, add the buyer's identity or ABN. The template covers all of these.
Tips for plumbers
- Show the job address and a short description of the fault and the fix: it helps if the customer later claims on insurance.
- If a government rebate or a third party pays part of the bill, show who pays what on the invoice.
- Add your plumbing licence number if your state requires it on business documents.
- Give every invoice a unique number (generator) and send it the day the job finishes.
Questions
Is an after-hours surcharge taxable?
Yes. It's part of the price of your service, so if you're registered, GST applies to it like the rest of the job.
Can I claim GST on a new van?
If you're registered and use it for the business, you can claim a GST credit for the business-use share, with a tax invoice. Cars have a GST credit limit; check the ATO's car limit for the year.
If the invoice isn't paid
Use a polite, consistent schedule: a heads-up 3 days before the due date, a reminder on the day, then +7, +14 and +30 days. The free reminder email generator writes them, and the late payment interest calculator works out interest if your terms allow it.
