Supporting Multiple B2B Standard Invoice Chains Under a Single Entity

Clearance and Reporting
1

Is it permissible to maintain two separate, independent chains of B2B Standard (clearance) invoices under the same registered entity in ZATCA?

Context:
Based on our current implementation, Standard invoices (B2B) submitted for clearance include a reference to the previous invoice’s hash and invoice counter, effectively forming a sequential chain from ZATCA’s perspective.

We have a business requirement to operate two distinct invoice chains simultaneously under the same entity. for example, to support separate business units, systems, or transaction flows while remaining compliant with ZATCA’s e-invoicing regulations.

Specific Questions:

  1. Does ZATCA’s system support multiple independent invoice chains under the same registered entity (same VAT registration number)?
  2. If yes, what is the technical mechanism to achieve this (e.g., separate CSID/device registration per chain)?
  3. If no, what is the recommended approach to handle this business requirement within the regulatory framework?
