General Authority of Zakat, Tax and Customs,
Greetings,
We would like to submit a technical inquiry regarding the implementation requirements of Phase Two of the e-Invoicing system, specifically in relation to invoice numbering sequencing within a multi-point-of-sale (POS) environment.
Our business operates under a single tax registration number and a unified commercial registration, with approximately seven (7) sales outlets/locations. Each outlet is equipped with an independent desktop-based POS system (not cloud-based), and each cashier issues and transmits invoices independently through the e-invoicing system. All POS devices have been separately integrated with the authority’s platform.
In this context, we would like to clarify the following:
Is it permissible for the invoice numbering sequence at each POS terminal (cashier) to start from number 1 and increment sequentially (1, 2, 3, …) without using branch-specific prefixes or suffixes (e.g., BR1-001, BR2-001, etc.)?
We emphasize that all invoices are issued under the same tax registration, but originate from different POS devices. Each invoice is already uniquely identified by a globally unique UUID and a distinct invoice transmission reference, ensuring no duplication or conflict within the central system.
We are fully committed to compliance with Phase Two requirements and kindly request your official technical guidance on whether this numbering approach is acceptable under the current regulations.
Your clarification on this matter will greatly assist us in ensuring full adherence to the technical standards.
Thank you for your support and cooperation.
Best regards,
