How Fawtara Muscat E-invoicing works
- Structured invoices: invoices are created in a standard digital format (PINT OM, based on Peppol), not as PDFs or paper.
- Accredited service providers: each business connects through an accredited service provider, which exchanges invoices with the buyer’s provider and reports data to the Tax Authority (the “five-corner” model).
- Validation: invoice data is checked before or as it reaches the buyer.
- Archiving: e-invoices must be kept for 10 years.
What to do now
- Map your invoicing: systems, volumes, invoice types, credit notes, and whether your sales are B2B, B2C or B2G.
- Check your data: customer VAT numbers, product codes and tax codes must be complete and correct.
- Talk to your ERP vendor: can it produce the required format and connect to a service provider?
- Choose an accredited service provider: compare cost, integration and support.
- Test before your deadline: run parallel invoicing and fix rejections.
- Train your team: sales, finance and customer service.
