A record of usage of the E-commerce system is created for each system user based on transactional documents transmitted in the E-commerce system. The record of usage is stored on a computer readable medium and retrieved in a periodic manner. An invoice is created for each user of the E-commerce system based on their system usage. System usage can comprise sending transactional documents, such as requests for quotes, sales proposals, signed contracts, and purchase orders.
