Accounts Payable Testing

Who this is for

Controllers, internal auditors, and finance directors in Taiwan who need independent testing of accounts payable for a stated period—often ahead of year-end close, a lender review, or reliance by external auditors.

What you receive

• A written testing plan covering population definition, sample method, and attributes tested
• Workpapers for each sampled invoice: PO match, receipt evidence, approval trail, and payment timing
• A findings memo ranked by risk, with recommended remediation owners
• A closing discussion with finance leadership to walk through exceptions

What is included

Three-way matching tests, duplicate-payment screening on the sampled population, cut-off testing around period end, and a review of payment authorization against your current approval matrix. We work from your ERP or AP export plus supporting PDFs and bank remittance files.

What is excluded

Full ledger reconstruction, tax filing, ERP configuration changes, and continuous monitoring after the engagement ends. Vendor negotiations and recovery of overpayments are outside this engagement unless agreed separately.

How we work

1. Scoping call — period under review, systems, sample size drivers, and reporting audience.
2. Population and access — AP listing extract, vendor master snapshot, and approval matrix.
3. Field testing — attribute testing on the sample with follow-up questions to AP staff.
4. Findings and close-out — draft memo, management responses, and final workpapers.

Duration and delivery

Typically three to six weeks depending on sample size and system access. Work can be delivered on-site in greater taipei or remote document review. You prepare extracts and contact people before kickoff; delayed access usually extends the timeline.
