  • Patent number: 7668779
    Abstract: A method and system for tracking and verifying estimates, invoices, and billing exceptions for charges billed to a customer by a vendor is disclosed. The vendor submits an estimate via a billing verification system. The system generates an estimate record and facilitates customer review of the estimate. The system also receives an invoice for the completed repair from the vendor and generates an invoice record. Based on the estimate record and the invoice record, the system can perform an audit to compare the invoice to the estimate. The system also enables the customer to review the invoice via the billing verification system to identify billing exceptions associated with any disputed charges. A billing exception record is generated in the billing verification system for each of the billing exceptions. The vendor is then notified of the billing exceptions. The vendor reviews and responds to the billing exception records via the billing verification system.
