We were recently introduced to a product called Courier from Deep Thought Software, and we were so impressed with the product that we joined up with Deep Thought Software to become one of their Preferred Developers in sharing this great solution to e-commerce clients in need. Courier is a piece of middleware that automatically enters sales from one's website into one's QuickBooks accounting system. This saves the merchant from having to use web sales reports to manually enter them into their bookkeeping system or deal with cumbersome export and import procedures.
