Note:
For invoice, credit note, debit note and receipt, the Supplier (also known as Seller) is always the party who iSSues (i.e. to Send).
For these source documents, the customer (also known as buyer) is always the party who receives.
There is always more work on the part of the seller than the buyer!
There may not always be credit note and/ or debit note. And a debit note might exist before a credit note.
Purpose: To inform credit customers of amount owing.
Note:
There is invoice only if credit purchase/ sale has taken place.

Purpose: To get approval from authorised personnel (e.g. Finance Manager, CEO etc) to make payment to credit suppliers
Note:
Payment voucher must be supported by credit supplier’s invoice.
A credit transaction must first have taken place before there can be a payment voucher.
Purpose: To inform credit supplier that payment by cheque has been made for specific invoice(s)
Note:
A credit transaction must first have taken place and payment must have been approved before there can be a remittance advice.
Tip: In exam, only use "remittance advice" as your answer if business is receiving payment, i.e. business is the credit supplier.
This is because the business receiving payment needs the cheque and the remittance advice so that the business knows which invoices it is receiving payment for.
For the business that is making the payment (i.e. the credit customer):
Receipt, payment voucher and bank statement are conclusive evidences that payment has been made.
Remittance advice alone is not sufficient evidence that payment has been made.
Purpose: To acknowledge that PAYMENT has been received from customer.
