Yes. The chart of accounts in Odoo is fully configurable, so you can load the Unified Accounting System account codes and names, in Arabic and English, and keep their hierarchy.

How we usually set it up

• Import the account list from a spreadsheet with codes, names, account types and reconciliation settings.
• Use account groups to reproduce the main and sub-levels of the unified system.
• Build custom financial reports that follow the layout your auditors expect, alongside the standard balance sheet and profit and loss.
• Use analytic accounts for cost centres and projects instead of creating extra ledger accounts.

Confirm the final mapping with your auditor before migrating opening balances, because changing account structure after go-live is far more work than agreeing on it at the start.
