QuickBooks Online

There's quite a lot to the app, but the support is first class. I've used their live chat today, and I've had quick replies and questions thoroughly answered by Lori who really understands the product. She helped me about a problem we were having with PayPal, she identified the issue and provided a solution, and set up a support ticket so I could share the solution with out book keeper. I can't see why you wouldn't use this app if you use QuickBooks, it makes life easier.
