Four original worked examples · choose by task
Four worked invoice checks before you make the customer copy
A sample is most useful when you can see the complete inputs, the result and the reason for a difference. Choose by the job you need to finish: copied template amounts, tax-invoice totals, service time records or previously invoiced quantities. These are four separate decisions, not four wordings of the same blank template.
Download the four-example packZIP contains inputs, worked review results and instructions. It is not a customer invoice or an automatic account import.
Start with the problem you need to resolve
Check quantities, unit prices and the copied subtotal
A copied template can look finished while one line still uses an old quantity or a typed amount. Review the arithmetic before reusing it for the next client. The result shows each discrepancy; it does not overwrite your document.
The fictional first line is 3 × AUD80 = AUD240. The second is 1.5 × AUD120 = AUD180, although the copied line says AUD170. Expected subtotal is AUD420; the typed subtotal AUD410 is AUD10 lower. The first line is left untouched.

A tax invoice template may mix a quoted inclusive fee with an exclusive service line. Adding GST again to the inclusive price can inflate the amount. This worksheet uses the GST amounts you enter and checks the footer against those lines; it never decides which treatment is legally correct.
In the fictional example, AUD200 exclusive plus AUD20 entered GST gives AUD220. AUD110 inclusive already contains the entered AUD10 GST and stays AUD110. The no-GST line is AUD50. Combined net is AUD350, GST AUD30 and total AUD380. A footer showing AUD35 GST is AUD5 above the line sum even though its grand total matches.

An hourly job can have two different record numbers but overlapping service times. A simple duplicate-ID check will miss that. Review one worker and one relevant job scope at a time before turning the time log into invoice quantities.
Fictional entries A and B total 210 minutes on 16 October, but cover only 180 clock minutes because 10:30–11:00 overlaps. Another 60 minutes on 17 October takes summed minutes to 270 and covered clock minutes to 240. The repeated 30 minutes is a review flag; it is not an automatic fee deduction or proof that either record is wrong.

A client may order twelve visits while nine are completed and seven already invoiced. Those numbers answer different questions. Compare both possible quantity balances, then use the billing basis in your actual agreement instead of assuming the order or completion record is enough.
In the fictional example, completed-but-unbilled quantity is 9−7=2. Ordered-but-unbilled quantity is 12−7=5. A proposal for 3 is one unit above the completed balance but within the ordered balance. Which model is appropriate comes from the agreement; the checker does not choose it.

For an ordinary Australian invoice template, choose the existing general or free template below. For a tax invoice, first independently confirm the correct GST treatment. For a job invoice, use verified service/delivery records and the agreed billing basis. After the relevant review, manually use the original invoice tool and inspect its real customer preview.

Keep a review trail
The pack results belong to fixed fictional inputs. After editing an online worksheet, rerun it and download its new review JSON. Keep the actual agreement, customer details, service logs, tax decisions and exported invoice separately. These checks do not verify payments or establish that an amount is chargeable.
Before using the result
Are these blank invoice templates?
No. They are filled review examples and independent checks. Use the linked existing template or original tool to make the actual invoice.
Do I need all four checks?
No. Choose the check that matches your actual risk. A matching calculation does not verify every detail of an invoice.
