Abstract: A method for evaluating adherence to funding rules includes: storing transaction data entries, each including a controlled payment number (CPN), a merchant category code, transaction date, and transaction data, where the CPN is subject to a first spend control setting a maximum spend amount during a predetermined time interval; identifying a group of transaction data entries that includes a transaction date within a predetermined period of time; identifying a subset of the group of transaction data entries where the merchant category code is one of a set indicated in a funding adherence rule; determining an adherence score for the CPN based on a ratio of a number of transaction data entries in the subset to a number of transaction data entries in the group; and modifying the first spend control to adjust the maximum spend amount based on the adherence score and funding adherence rule.
