What enters the sample — and what does not
Use this page to brief your controller before you request a review. It mirrors the checklists we use on Full Invoice Compliance Audits for accounts payable teams.
Core tests in every full audit
PO quantity and price versus goods receipt versus tax invoice lines. Tolerances follow your written policy; if none exists, we note the gap.
Buyer and seller identifiers, tax status, invoice date, and GUI number consistency with the vendor master for Taiwan B2B invoices.
Sample of invoices against the current approval matrix — amount thresholds, secondary sign-offs, and evidence of buyer confirmation when prices change.
Exact invoice number repeats plus near-matches on amount, date, and vendor within the population window.
Aged exceptions categorized by cause so the findings pack separates process issues from one-off vendor errors.
Outside a standard sample
We do not rewrite accounting entries, file tax returns, or issue assurance opinions. Intercompany settlements and payroll-related payments stay out of scope unless you add them in writing. Currency revaluation journals are noted only when they distort invoice matching.
Population choices that work well
- One calendar month for a single entity
- One vendor category across a quarter (freight, facilities, professional fees)
- All invoices above a cash threshold you define
Narrower populations finish faster and still surface the patterns AP needs before close.
