This is by far the best, and absolutly the only truly professional invoicing application in the App Store. Others try to imitate what BillDu does, but don't even come close. If you want a resonably priced invoicing & data storge application, look no futher, this is the cream of the crop We've been using BillDu for our business in Bermuda for many years and have never had a single problem, outage, loss of data or a single moment of downtime. The application is intuative, imaginative and helpful
