Tax coding
SST and withholding treatment in the application
Whether sales tax, service tax, exempt supplies, and withholding are applied inside the invoice flow the same way finance explains them at month-end.
Codes that look tidy in a demo
Invoice applications often ship with a neat list of tax codes. Live invoices pick up defaults from the vendor master, from the PO, or from a clerk’s last choice. We sample across standard-rated, exempt, and out-of-scope supplies, and we look at imported services where withholding may also apply.
This is not a tax opinion on a particular supplier contract. It is an examination of whether the application applies the treatments your finance team says it uses.
Month-end versus invoice-day
We compare a sample of invoices to the figures that later support SST returns. Where a spreadsheet sits between the application and the return, we say so plainly. Hidden reconciling items are findings, not footnotes.
