Invoice reference-check list

The item code exists in the current catalogue

Look the code up on the support items register — codes are retired and added every year, and a code that was valid last year may not appear in the current file.

The item name matches the code

Transposed digits are easy to miss. Compare the invoice line description with the official item name for that exact code.

The service date sits inside the item's effective dates

Each catalogue entry carries effective dates. Entries around 30 June / 1 July often span two catalogue years — compare against the catalogue in force for the service date, not the invoice date.

The rate is at or below the published price limit

Compare the invoiced rate with the limit for the geography that applies (national, remote or very remote). Remote loadings only apply where the official file lists them.

The unit matches

An hourly item invoiced per day (or the reverse) changes the total by an order of magnitude. The official unit is on every item page.

Quotable items have an agreed quote on file

Some items carry no published limit and are marked quotable in the official catalogue — the reference point is the quote that was agreed, not a price limit.

Cancellation entries match the item's flags

The catalogue flags whether an item is subject to short-notice cancellation rules. For cancellation lines, compare against those flags and the official pricing document.

Provider details are consistent

ABN and business name on the invoice match the service agreement and prior invoices from the same provider.

The service agreement covers the line

Item, period and rate appear in (or are consistent with) the current service agreement.

The arithmetic holds

Quantity × rate = line total, and the invoice total is the sum of its lines.
