Invoice Sampling Review
Targeted testing of a defined invoice population when you need comfort on a period, vendor group, or cut-off window.

Purpose
Use this when a full cycle audit is more than you need — for example before closing a shared-service transition, after a surge in temporary staff, or when external auditors asked for extra AP comfort on one quarter.
Scope
We agree a population (period, company codes, or vendor category), draw a risk-weighted sample, and test each voucher for authorisation trail, supporting documents, coding reasonableness, and payment agreement to the invoice. Results are listed line by line.
Deliverable
A concise sampling memo with exception rates, illustrative examples, and whether expanding the sample is warranted. No lengthy methodology appendix unless your board asks for one.
Next step
Send the population description and any vendor groups of concern via contact.
