Hello,
We are facing an issue regarding ICV and PIH, as we have only one CSID. We send invoices through it, but I was previously counting the ICV based on the invoice type, whether simplified, tax, or credit note. Now, I want to change it based on the CSID.
My questions are:
1. Are there any issues with the invoices we have already sent?
2. Does the new ICV that I will generate need to start with sequence number 1, or should it start from the last number I sent to the authority?

@Malik thanks i already discussed it with zatca team
and this is reply from zatca
for invoices already sent with incorrect ICV and PIH sequences, you can submit a failure notification using service [https://zatca.gov.sa/en/E-Invoicing/FailureNotifications/Pages/VerifyTaxpayer.aspx](https://zatca.gov.sa/en/E-Invoicing/FailureNotifications/Pages/VerifyTaxpayer.aspx) . No action needed to go back and change ICV PIH values retrospectively. Every new CSID should have Invoice Counter Value (ICV) starting with 1 and incremented by 1 for every new document (irrespective of type of document Standard invoice, Simplified Invoice, Credit Note, Debit note and irrespective of status of invoice whether accepted / rejected / accepted with warning).
