When a QuickBooks Online user wants to automatically apply a credit memo transaction to a customer invoice, the Automatically Apply Credits checkbox must be turned on in which area?

Answer: Receive payment section of the invoice

Explanation: Applying a credit memo on an invoice can be done through the receive payment section of the software. Before a credit memo is applied, an invoice would have been issued and it is either a payment is received in cash or check or a credit memo is issued to the customer on that particular invoice.

To apply the credit memo on any invoice, the receive payment option is clicked, then the credit memo is applied on the invoice applicable to remove the outstanding debt on that particular invoice.
