Fictional worked example · not a customer case
Check one specific result
For a fictional 90-minute service, a previously agreed two-hour minimum at AUD50/hour gives AUD100.00; actual time alone gives AUD75.00. The extra 30 minutes are visible as a minimum adjustment, not represented as additional work performed.
Method and boundaries
Billable duration under this entered model is the larger of actual and minimum minutes. Multiply by the same hourly rate and round once to cents. If actual service exceeds the minimum, actual minutes drive the result. A fixed minimum dollar fee is a different model.
The calculator does not establish that a minimum fee was disclosed, accepted or enforceable. If a service ended early or the booking was disputed, reconcile the agreement before using the number. No cancellation fee or payroll entitlement is calculated.
From a reviewed number to an invoice
- Confirm the actual customer, scope, period and approved charging basis.
- Match each row to source job records; fictional examples are not customer data.
- Download a manual review record if useful; it does not replace original invoices or accounting records.
- Manually enter appropriate AUD line items in the tool, check the preview, then export the PDF or image yourself.

Questions before invoicing
Does this result create or change an invoice?
No. This page calculates a manual review only. Nothing is sent to an account, saved to an invoice draft or automatically copied into ABN Invoice. Review the agreement and enter an approved customer document yourself.
