Yes, testing is an important part of the Oman e-invoicing implementation process. OTA's service-provider requirements include prescribed technical testing, while the Oman PINT specifications provide the technical rules and validation framework used for e-invoices.

OTA's published FAQ also references the Oman Test Suite for OpenPeppol. The practical taxpayer testing environment, including credentials and pre-production connectivity, depends on the selected accredited service provider and the current rollout arrangements.

Businesses should therefore test their ERP mapping, invoice generation, validation, exchange, error handling and relevant transaction scenarios before moving into production.

Key points

  • Testing is part of the Oman e-invoicing readiness process.
  • ASPs must complete OTA-prescribed technical testing.
  • Oman uses PINT OM technical specifications and validation rules.
  • Taxpayers should test ERP-to-provider integration before production.
  • Invoice and credit-note scenarios should be tested.
  • Businesses should confirm the available taxpayer test environment with their ASP.
