When invoices sit in a holding folder for weeks, the root cause is often intake, not matching skill. These three fields prevent most of the stalls we see on Taiwan B2B tax invoices.
1. Vendor GUI number vs master file
If the seller identifier on the tax invoice does not match the vendor master, stop. Renamed companies and branch offices create silent mismatches that later look like “system” problems. AP should confirm the master update with purchasing before the invoice is coded.
2. Tax status that matches the purchase
Zero-rated and taxable lines mixed on one invoice without a clear split create coding fights. Clerks should ask the buyer to confirm the nature of the purchase on the same day the invoice arrives, not after goods receipt closes.
3. PO reference on the face of the invoice
Service vendors often omit PO numbers. Without that reference, three-way matching becomes detective work. A one-line policy — “no PO reference, no intake” — sounds harsh and saves hours at close.
Print these three checks on a card near the intake desk. The Vendor Invoice Policy Walkthrough we run with clients expands each point with examples from your own reject pile.
