A method of processing professional services invoices begins with importing the invoices in electronic form and storing invoice data from the invoices in a database as electronic invoices. The electronic invoices are published on a computer network to permit access to the electronic invoices by reviewers connected to the network. On-line quality control and peer reviews of the electronic invoices are conducted to determine if adjustments to charges on the invoices should be applied. The method includes generating electronic client invoice reports reflecting the adjustments made by the quality control and peer reviewers and transmitting the client invoice reports to the client.
