This app has really helped my business It’s so easy to bill that my revenue has actually increased since I can add my services with just a few strokes. Also saves time of manually generating invoices. The other apps that I have used just did not cut it, too much entry... I'm Already starting to accumulate some good history and financial info. It does take some time and effort to set up but is well worth it once you’re rolling. I tried another app but the information was on a server and I needed a connection for it to work, not so good for me because of my sometimes poor connections. This app has everything stored on my iPhone and works smoothly with my existing contacts and calendar. They should charge a lot more for this app. Great Job
