QuickBooks Bridge by Parex

Relatively easy to set up, and runs very smoothly. I have had a couple of minor issues over the 8ish months I have used the app, and all have been quickly resolved within hours of reporting them. To me the high quality customer service is worth more than a "flawless" experience; there is always going to be some issue at some point, and knowing that customer service will be there when I need them is peace of mind. Well worth the $, wouldn't change a thing.
