Cross-examination

The procedure belongs to Türkiye's refund process, and the term does not map onto an English-language audit step of the same name. Invoices behind a refund claim are listed, the supply chain is traced backwards, and the amounts are compared with the records of the party that issued them. The accountant does not stop at a copy of the invoice: the counterparty's ledger entry, the bank trail behind the payment and the period the document falls into all have to line up. The findings are written into minutes that become an annex to the certification report. The work therefore resembles proving that a chain of documents looks identical on both sides, rather than checking a single piece of paper.

Cross-examination asks the same question reconciliation asks: does one transaction look the same in two sets of books? What differs is who asks it and at what level of detail. Reconciliation runs between two trading partners and starts at the balance; cross-examination comes from outside and works document by document. For an unprepared company that difference is expensive. If the invoice list, the payment matching and the link to the bank statement are scattered, the same information gets gathered one item at a time and the process stretches over weeks. Where invoices, payments and bank movements are already matched with a stated reason for each match, producing the requested file becomes a reporting exercise.

Three things get misread. It is not a confirmation letter: the counterparty saying it agrees is not enough, since a ledger entry and a payment trail are expected. It is not an accusation: it is a verification step whose ordinary outcome is that everything ties. And its scope is not the company's choice. The floor is drawn by mandatory thresholds set in the regulations, and documents that stay below a threshold one by one can still be pulled into scope once purchases from the same supplier are added up over the period. Above those thresholds, deciding which further invoices to examine is a judgment that belongs to the accountant signing the report — and because the thresholds are set by communiqué and revised from year to year, a file built on last year's figures can fall short.
