FICTIONAL INVOICE EXAMPLES
All suppliers, transactions and review decisions are invented for this example.

Open the HTML files in your browser. Each is a complete printable invoice.
You can print each file to PDF from your browser if needed.

LINE ITEMS WORKBOOK
Use the three original invoices. Compare the item rows, quantities, units and
prices with the Line items sheet. Invoice register compares calculated amounts
with source totals. Change a quantity to see the difference, then restore it.

AUDIT WORKBOOK
Four source files are received. alder-1048-copy.html is a second copy of the
same invoice, not a fourth distinct bill. The example excludes it after a
source check. Change Decision from Exclude to Keep to see the included total
change from USD 1,440 to USD 2,133. Restore Exclude after the exercise.
Review keeps an unresolved amount out of the included sum and increases the
review count. Review the source inventory as well as that count.

cedar-301.html is deliberately missing. Its amount is unknown.
Keep its source-inventory status Missing and the review issue Open until you
receive and check the document. Enter your own reviewer and resolution notes.
The status and review log are maintained manually; they do not synchronize.

These are small worked examples, not a production audit system. If you extend
the sheets, extend the calculation ranges and check the new rows and totals.
