Who this is for

Accounts payable supervisors and finance controllers who need an independent check on invoice quality before payment runs or year-end close. Typical clients process hundreds of Taiwan B2B tax invoices each month and want evidence that matching and tax fields hold up under scrutiny.

Result you receive

A written findings pack that lists each exception by invoice number, vendor, cash impact, and recommended correction. We walk your AP lead through the pack in a scheduled call so the team can clear holds without guessing.

What is included

  • Agreed invoice population (month, entity, or vendor group)
  • Three-way match sampling across PO, goods receipt, and tax invoice
  • Checks for duplicate payments and repeated invoice numbers
  • Taiwan e-invoice field review: GUI number, tax status, buyer/seller identifiers
  • Approval trail sampling against your matrix
  • Ranked exception register and sample worksheets
  • One findings walkthrough (up to 90 minutes)

What is excluded

  • Bookkeeping or posting corrections in your ERP
  • Formal attest opinions for external auditors
  • Tax filing preparation or representation before authorities
  • Continuous monitoring software licenses

How the engagement runs

  1. Intake — You share exports or folder access and confirm the population.
  2. Fieldwork — We test the sample over five to ten business days, depending on volume.
  3. Findings — You receive the register and worksheets.
  4. Walkthrough — We review priority exceptions with your AP lead.

Duration and location

Most single-entity reviews finish within two weeks of receiving complete files. Work is desk-based from our Banqiao office with optional on-site file days in Greater Taipei when paper folders still matter.

Preparation from your side

Export of open and paid invoices for the period, vendor master extract, PO and receipt extracts where available, and a current approval matrix. If paper folders remain, we schedule an on-site day.

Constraints

We need a named AP contact who can clarify holds within two business days. Incomplete populations delay the findings date.
