Techniques for performing an accounts payable process may include receiving transaction data including at least one of invoice data, purchase order data, and vendor data; and verifying a transaction by matching a dynamic data set of client-specified multi-dimensional criteria to the transaction data. An accounts payable system may include a host system in communication with one or more client systems. The host system may include a matching database configured to receive an accounts payable file including at least one of invoice data, purchase order data, and vendor data; and verify a transaction by matching a dynamic data set of client-specified multi-dimensional records to attributes of the accounts payable file.
