I trust this message finds you well. I am writing on behalf of our customer, seeking clarification on a matter related to invoice sequencing within their accounting system.

Current practice involves a unified sequencing approach for invoices, credit notes, and debit notes, where the system assigns a sequential identifier (invoice reference) regardless of transaction/document type. For example, if we create 2 invoices, followed by a credit note, and then the 4th invoice, the sequencing is 001, 002, 003, and 004, respectively.

Is this acceptable from VAT regulation perspective.

We are aware of e-invoice resolution and requirement of UUID and ICV, PIH and invoice hash and we have readiness on this e-invoicing part for our customer

Your guidance on these matters is invaluable to us in maintaining compliance with the regulatory framework. We eagerly await your response.

@chanya Yes it’s a valid scenario.
