Abstract: Aspects of this invention provide for allowing a customer which has been issued trade credit to use that credit through an open loop payment network. A purchase from a merchant using an open loop payment network associated with that customer's trade credit account is requested to be approved. A credit manager can then approve or deny the transaction. Once the transaction is approved, the credit manager is provided transaction information through a number of processes described herein. The credit manager also initiates the payment of the merchant through a supporting bank. Once the transaction information is received by the credit manager, the credit manager can then issue an invoice based on the trade credit terms agreed upon when the customer was issued trade credit.
