Credit Invoice Payment

Dear Support Team,
We are generating tax invoice with credit as payment mode. How the payment for invoices can be captured for the invoices once the payment is received. Should we only change the payment amount and validate it again with zatca?

Also Clarify how to handle situations where clients request credit note (CN) invoices without clearing full payment for the previous invoice.

Hi,
There are following documents which can be created,

B2B
Standard Invoice
Simplified Invoice (as an option for supplies where the value is below SAR 1,000).
Credit Note
Debit Note
Prepayments

B2C
Simplified Invoice (irrespective of value of supply)
Credit Note
Debit Note
Prepayments

thanks
