We examine how invoices are applied in your books — cut-off, matching, credit notes, and period recognition — then report what holds and what needs correction before sign-off.

Flagship engagement

Full invoicing application audit

A structured review of how supplier and customer invoices enter journals, match goods receipts or delivery notes, and land in the correct reporting period.

Finance controllers call us when month-end feels rushed, when an external auditor has raised invoice sampling questions, or when a new billing clerk has inherited unclear posting habits. We sample applications, trace supporting papers, and write findings in plain language for management and the statutory auditor.

  • Cut-off testing around period ends
  • Three-way matching of PO, receipt, and invoice
  • Credit note and debit note application review
  • Written findings with recommended corrections

From the field

What clients notice after the working papers land

“They caught a batch of December supplier invoices still sitting in January because the stamp date was treated as the posting date. Our external auditor closed the cut-off point without a second sample.”

Nattapong S. · Group controller, logistics group

“The first week felt slow while they rebuilt our matching trail. Once that was done, the findings were specific enough that accounts payable could fix postings without guessing.”

Areeya K. · Finance manager, hospital supplies distributor
