Customer receipts

A client pays for a certain cash sale partly by cash and partly by bank transfer. Kindly assist on how we can generate a receipt simultaneously capturing both the bank and cash account

Use invoice, then add a bank receipt and a cash receipt to it.

You cannot, because the two receipts debit different accounts. However, @eko’s solution puts all the transactions (original sales invoice, receipt for cash, and receipt by bank transfer) onto one piece of paper.
