I’m working on an ERP software where:

1. Sales Invoice numbers start from **1001** and increment upwards.
2. Credit Notes start from **1001** and increment upwards.
3. Debit Notes start from **1001** and increment upwards.

Is there any issue with using the same starting number for Sales Invoices, Credit Notes, and Debit Notes when submitting to ZATCA? Will ZATCA require unique sequencing across all document types, or can they have independent numbering?

Any guidance or best practices would be appreciated!

Hi,

If you’re talking about ICV, then it has to be unique per linked CSID. A solution to your case, is to onboard three unites for the mentioned three types.

Dear @arjun_tech24 ,

this is acceptable only in the IRN which is the invoice reference number, you can create your own sequence which suits your business needs.

For the ICV, it’s a must to maintain the sequence of (1,2,3.etc.) incrementally with each generated new invoice, this sequence should be across all of the documents (simplified & standard invoices and notes) per each CSID that is onboarded.

Regards,
