System and method for real-time three-party transaction processing

An intermediation server comprising:

• a communications interface;
• and
• a processor interconnected with the communications interface, the processor configured to:
• receive invoice data defining a price payable to a vendor for supplying a product to a customer;
• prior to initiation of a payment to the vendor for supplying the product:
• extract, from the invoice data, a vendor identifier corresponding to the vendor;
• select, based on the invoice data, a customer identification mechanism;
• determine, in association with the invoice data, a customer identifier corresponding to the customer according to the selected customer identification mechanism;
• retrieve a payer identifier corresponding to a payer associated with the customer;
• retrieve, based on at least the payer identifier, a transaction policy;
• according to the retrieved transaction policy, allocate an eligible portion of the price to the payer identifier, and allocate a remaining portion of the price to the customer identifier;
• and
• generate and transmit, via the communications interface, payment data for initiating a payment of the eligible portion from the payer to the vendor.

A system for real-time three-party transaction processing, comprising:

• (i) a vendor computing device associated with a vendor, and configured to generate invoice data defining a price payable to the vendor for supplying a product to a customer;
• (ii) an intermediation server configured to:
• receive the invoice data via a network;
• extract, from the invoice data, a vendor identifier corresponding to the vendor;
• determine, in association with the invoice data, a customer identifier corresponding to the customer;
• retrieve a payer identifier corresponding to a payer associated with the customer;
• retrieve, based on at least the payer identifier, a transaction policy;
• according to the retrieved transaction policy, allocate an eligible portion of the price to the payer identifier, and allocate a remaining portion of the price to the customer identifier;
• generate and transmit payment data, via the network, for initiating a payment of the eligible portion from the payer to the vendor;
• and
• (iii) a customer computing device associated with the customer, the customer computing device configured to:
• receive the payment data from the intermediation server via the network;
• and
• present the payment data for receipt by the vendor computing device to execute the payment of the eligible portion.
