Add a ZATCA-compliant customer

To issue a ZATCA-approved tax invoice, the customer's data must be complete and compliant. A missing mandatory field prevents the system from completing e-invoicing.

Path: Accounting ← Customers ← New

1. Open Accounting then Customers and click New to create a customer.
2. Choose the type: Company for a business or Individual for a person, and enter the full Name.
3. In the Tax ID / VAT field enter the 15-digit tax number that starts and ends with 3 (for VAT-registered customers).
4. Fill the full address: Street, District, City, and the 5-digit postal code.
5. Enter the 4-digit Building Number in the ZATCA-required building number field.
6. Set the country to Saudi Arabia, and enter the Email and mobile to send invoices and ZATCA notifications.
7. Save via save (☁); if a warning appears, the system blocks saving until the mandatory fields are complete (BR-KSA rules).
8. Create a test invoice for this customer and confirm no ZATCA alert appears before relying on the record.
