When does the invoice batch process change an invoice status to paid?

The correct answer signifies that an invoice status is changed to paid when a customer completes their payment for that invoice. This is a standard practice in billing systems, where the payment received from the customer directly triggers an update in the invoice status.

Updating the status to paid upon customer payment ensures accurate tracking of financial transactions and provides a clear indication of which invoices have been settled. It reflects immediate changes in the accounts receivable records and assists in managing cash flow effectively.

Other options, such as changing the status immediately after billing, one week after the due date, or at the end of the month, do not align with the typical process of recognizing payments. Each of these alternatives would potentially lead to inaccuracies in billing records and not reflect the actual financial state of the invoices. Hence, linking the change of status directly to the payment received is the correct and most logical approach.
