Customer direct debits

When a vendor has an agreement with a customer to collect payments automatically, the vendor sends a payment request message to the vendor's bank. The vendor's bank is prompted to collect the customer payment by requesting money from the customer's bank. Typically, the communication between the vendor and the bank is electronic.

A remittance advice, manual or electronic, is sent by a vendor to the customer to indicate which invoices are being paid. Typically, they include invoice numbers and invoice amounts.
