Abstract: A computer-implemented and Internet-based method of managing Accounts Receivable (AR) information includes steps of receiving a customer request for remote Internet access to AR information (such as pending invoices) owned by vendor; retrieving the customer's AR information from a database and enabling the retrieved AR information to be remotely displayed for the customer and enabling the vendor's internal personnel to retrieve and to display the customer's AR information simultaneously as the AR information is displayed for the customer. The customer may dispute an invoice accessed from the database by accessing the vendor's Web site and by selecting a reason code for the dispute and at least a disputed amount to create a pending Credit Memo Request, all without direct manual involvement from the vendor.
