Tax, UOM & Charge Mappings

Tapr Settings includes mapping tables so extracted and outbound documents align with PEPPOL tax categories, units of measure, and charge/allowance codes — and with your ERP accounts where relevant.

Open Tapr Settings → General (and related tables) for:

  • UOM Mapping
  • Tax Account Mappings
  • Charge / PEPPOL reason code defaults (where configured)

Map invoice tax categories / rates to ERP tax accounts or internal codes used when posting AP invoices. Incomplete mappings often surface as posting errors or incorrect VAT buckets.

Vendors and ERPs use different unit strings (EA, PCE, HUR, …). UOM mappings normalize units so line quantities post cleanly.

Sales and purchase invoices support header charges (allowances/charges). Outbound PEPPOL validation can block send when charges are unmapped or use wrong-direction codes.

  1. Prefer charge types that match PEPPOL charge codes your profile expects.
  2. Review auto-classified vs user-set charge types before Ready to Send.
  3. Fix unmapped charges when send validation fails.
