Accounting Software in Oman
Oman introduced 5% VAT in 2021. Businesses above OMR 38,500 must register. Bilingual Arabic/English invoicing is required.
DocMakBooks is built for companies operating across logistics around Sohar and Duqm, fisheries, tourism, construction and a growing In-Country Value supplier base. Registration, filing, payroll and document rules are pre-configured for Oman Tax Authority, so your ledger is filing-ready from the first invoice rather than reworked at period end.

E-invoicing status

Import VAT is settled through the Bayan customs system and claimed back in the same quarterly return where recoverable.
Payroll and banking
PASI social insurance applies to Omani nationals at 11.5% employer and 7% employee contributions, and end-of-service benefits accrue for expatriate staff under the Labour Law. Salary files are produced as WPS file uploads via the Ministry of Labour portal and the employer's bank, and bank statements import from Bank Muscat, Sohar International, Bank Dhofar, National Bank of Oman.
