Methodology
How Wise Digital conducts a financial audit of invoice processing applications — from scoping to the findings briefing.
Financial audit of invoice processing applications is not a generic IT health check. We follow the money: how a supplier invoice becomes an obligation, how that obligation is authorized, and how cash leaves the entity.
Scope the application boundary
We confirm which application is the system of record for invoices, which feeds the general ledger, and where payment files are generated. Shared-service centers and multi-entity setups are mapped before samples are chosen.
Walk the invoice lifecycle
With AP supervisors present, we observe vendor master changes, capture methods, coding, approval routing, match exceptions, and payment proposal release. Narratives alone are never enough; we need to see the screens and the paper trail beside them.
Sample with purpose
Samples favor periods of stress — quarter ends, cutovers, rush payments, and high-value vendors. Attributes cover authorization, evidence of receipt or contract, and agreement to the amount paid.
Test access and segregation
We compare who can create vendors, change bank details, approve invoices, and release payments. Conflicts that look minor on an org chart often matter when one person holds two of those rights.
Report in finance language
Findings cite the invoice stage, the financial statement risk, and a practical management action. We avoid jargon that belongs in a product brochure. Draft reports go through a factual accuracy check with your team before finalization.
What you prepare
Export capability for invoices and payment runs, a contact who can schedule walkthroughs around close, and any prior internal audit notes on AP. If Korean electronic tax invoices (e-tax) interact with your capture process, note that early so we include the handoff in scope.
Where this leads
Most clients move from methodology into our full financial audit engagement. Others start with a control walkthrough when the question is narrower.
