Imagine the following scenario: you want to do business with a trading partner like, for example, Wal-Mart, but they will only work with you if you are able to handle EDI integration. CommerceHub is a SaaS company that provides EDI processing. They can receive Purchase Orders (850) as well as send Invoices (810) and Advanced Ship Notices (856) on your behalf, while the BirdDog CommerceHub Connector seamlessly moves the data in and out of your system.
