An Invoice-Receipt is like a Invoice, but it is marked as paid as soon as it is issued, so there is no need to issue a separate Receipt.

You can issue an Invoice-Receipt after a service is provided or a product is delivered and the payment is received. It also confirms that a service was provided or a product was sold right after receiving the payment.

If you need to request payment before providing a service or delivering goods — it’s better to issue an Invoice. After the payment is received, you should then issue a Receipt for that Invoice.
