Step-by-step explanation:
The document that accompanies the customer's payment is the remittance advice.
A remittance advice is a document sent by a customer to a vendor along with a payment. It provides detailed information about the payment, such as the invoice numbers being paid, the amount paid for each invoice, and any remaining balance.
This document helps the vendor reconcile the customer's payment with their records and ensures that the payment is applied correctly.
