Enabling B2C Invoicing for Already Onboarded EGS with B2B

Clearance and Reporting

Dear ZATCA/Fatoora Support Team,

We are a solution provider, and we have onboarded a business unit for invoice type 1000 (B2B). The unit is successfully generating and submitting B2B invoices to ZATCA without any issues.

Now, the same business unit has started generating B2C invoices from the same EGS, using a continuous invoice series (e.g., INV-0091 to INV-0096 are B2B, INV-0097 is B2C, and INV-0098 is again B2B). The taxpayer now needs to submit the B2C invoice (INV-0097) to ZATCA.

We seek your guidance on the following points:

  1. Can the existing B2B onboarded EGS be converted or updated to support both B2B and B2C invoices?

  2. Do we need to re-onboard the same EGS with CSR configuration of invoice type 1100 (to support both Standard and Simplified invoices)?

  3. Some customers are government entities without VAT, so the taxpayer needs to issue invoices without VAT for such cases. Please confirm the correct approach for handling VAT-exempt invoices.

  4. Kindly provide step-by-step guidance or official instructions from ZATCA/Fatoora on how to enable B2C invoicing for already onboarded business units.

We appreciate your assistance and look forward to your response.
