    This addon for WHMCS is, by far, the best tool I've found for those of us who take orders via WHMCS and accounting via Quickbooks. It can sync both ways between Quickbooks and WHMCS in the background. It has it's quirks, but once optimized with the settings you want, works flawlessly to sync data behind-the-scenes between the two systems. You need to keep Quickbooks and the Web Connector open on your computer at all times for it to work, but it creates customers, invoices & products on both sides, automatically mapping customer orders to the proper customers in Quickbooks, and also allows you to map payment types to different deposit accounts. The only thing I can complain about is the price... Paying $250 annually for a small business, when there are many other expenses, is a difficult proposition. I don't mind $250 as the initial price, but perhaps a lower renewal fee would be in order, especially since now that most bugs are worked out, there aren't very many frequent updates.
