Two invoices for one delivery went into the books
One delivery arrived twice, by email and with the courier under a different number, and both invoices were posted. RestoAudit matched supplier, date, amount and line composition and put the documents side by side. The 386 € stock gap was closed before month end: the second document was cancelled and the supplier issued a correction.
