    This is a super helpful tool for our company and highly recommend to anyone receiving payments in WHMCS and using QuickBooks for accounting.
    This add-on was simple to set up and set up relations between the two programs. We now have the ability to report payments received in WHMCS in a very detailed manner.

    Before we were spending hours manually entering payments in QuickBooks, but with this integration it's one simple click of the button.

    I highly recommend this product to anyone looking to save time and receive detailed reporting in QuickBooks. Also support has been very helpful throughout the entire process - providing prompt and clear answers to any questions I've had.

    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.
