Can I Keep My Existing Accounting or POS Software?

Possibly. Fawtara does not automatically mean every company must replace its existing business software.

What OTA says

OTA's current FAQ states that ERP systems can be retained depending on the arrangement between the taxpayer and its accredited service provider, and that Oman PINT specifications are used for mapping.

Your three options

Upgrade

Your current vendor adds Fawtara support.

Connect

Your existing software sends invoice data to a compliant connector/service layer.

Replace

Move to a new invoicing system if the current product cannot support the required process.
