Direct answer

PINT OM is the Oman billing specification published by OpenPeppol. It covers invoice and credit-note transactions, with semantic models and validation rules. An implementation should map the merchant's source fields to the current specification and test both document types. It should not assume that generating XML alone completes OTA onboarding.

The short version

  • Invoice and credit note are separate transactions.
  • Map source fields before building export code.
  • Check the current specification version during testing.

Begin with the source record

Identify invoice number, dates, seller and buyer identities, tax treatment, lines, totals and reference to an earlier document when correcting it. Keep the source record readable so finance can explain how each PINT OM value was calculated.

Validate beyond syntax

A well-formed XML file can still fail business rules. Use the provider's agreed test environment and current PINT OM rules to inspect accepted and rejected cases. Record which system fixes a field and who retries the document.

What to check in your own setup

  • Write a field-level mapping with sample values.
  • Test one invoice and one credit note.
  • Record the specification and provider version used in acceptance tests.

Does PINT OM certify our POS?
