Abstract: A computer-implemented method includes registering at least a first merchant and a second merchant, the registering including a consent process for payment card network access. The registering enables a registered merchant to post equity financing auctions and to bid on posted equity financing auctions. When a posting for an equity finance request is received from a registered first merchant, a validated aggregate historical data for the registered first merchant can be obtained from the payment card network. When a bid, which includes an amount of finance offered and requested equity, is received on the equity finance request from a registered second merchant, a set of transaction data for the registered second merchant is obtained from the payment card network and a score is generated for the registered second merchant based on conditions in the equity finance request using the set of transaction data and the bid.
