Abstract: Fees due from transactions in electronic commerce are processed by building a transaction information database with transaction event objects based on events in each transaction. After retrieving fee rules from a fee rule database, a determining step detects if the fee rule applies to information in a transaction event object. Then, if the fee rule applies, a calculating step calculates the fee based on the fee rule and the information in the transaction event object. A fee object for a recipient entity is created based on the fee calculated by said calculating step and is stored in a payment database. An accumulating step sums the payments for a recipient entity from the fee objects in the payment database. The fee rules are general fee rules and specific fee rules. The general fee rules are applied to information in a transaction event object, and a calculating step calculates a general fee based on the general fee rule and the information in the transaction event object.
