1. It follows Oman's tax rules
VAT is 5%, filed with the Tax Authority every quarter within 30 days. The software should fill the return from posted documents and keep amounts to the baisa.
2. E-invoicing
Oman's Tax Authority is introducing e-invoicing (Fawtara). Ask how the software will meet it when your business is in scope, and make sure today's invoices carry the required fields in Arabic.
3. Payroll
Payroll must handle Social Protection Fund contributions for Omani staff and end-of-service for expatriates, with payslips in Arabic and English.
4. Currency and decimals
Amounts in OMR to three decimals: a system built for two will round and drift.
5. Arabic that is not an afterthought
Every screen, report and printed document should read right to left in Arabic as well as in English, with the Arabic text a native speaker would write. Try printing an invoice in both languages before you decide.
6. Your data, your accountant
Books should never be edited after the fact: corrections are new entries, with an audit trail. Check that you can export everything, and that your accountant can work inside your books with their own login and a role you choose.
7. The price, in your currency
Compare the price for the plan you will actually need in a year, in OMR, with users, companies and payroll employees included. Aqid ERP's plans in Oman start at OMR 8.1 a month, and you can start free.
