Post payment receipt format

As a business, we need to maintain some standards, e.g. we need to keep formats for invoices, payment receipts etc. same in every case. But in case of prepayment, we need to generate an invoice as per ZATCA guidelines and need to share that invoice with the customer. What about the payments which are not prepayments, what format should we follow in such cases?

Hi,
In ZATCA reporting you are reporting following documents,

B2B
Invoice, credit note, debit note, prepayment

so what you mean here by payment as here you are reporting to ZATCA a prepayment invoice not payment. thanks
