Check the work log before the invoice run
In the fictional register, J-01 and J-02 are completed jobs worth A$400 together. Only J-01 has an invoice mapping for A$180, so J-02 appears as an unmapped A$220 job. Planned J-03 is excluded from completed-work value. This is a list for investigation, not an instruction to bill every gap automatically.
Keep references stable across both tables
Client and job IDs must match exactly. A different spelling is not silently treated as the same customer. When one invoice covers several jobs, enter each allocated job amount instead of repeating the invoice total. Several billing rows for one job can be legitimate deposits or staged claims, so the result flags them for review rather than calling them duplicates.
Resolve gaps with the original evidence
Check service notes, approval, cancellation, scope changes and previously issued invoices. Missing records can explain an apparent shortfall. Once a genuinely unbilled job is confirmed, prepare its description and service date in ABN Invoice. The checker does not inspect your account history, import PDFs or decide that a customer owes the entered amount.
Keep a review record
Run the check again whenever an input changes. Invalid or incomplete input clears the previous live result and disables download, so an old answer is not presented as current. Downloads contain the check table only; they are not a tax invoice, payment receipt or successful invoice export. They do not update drafts, history, login or payment status.
