I purchased invoice 2 go and as a standalone on the Samsung note. It worked well as a standalone but when I tried to integrate/sync with the desk top version it was clunky and I had a lot of problems with it, still am. The tec support is awful. They take about 4 days to respond and then only when you bombard them with e-mails and when they do bother to answer its generally to send a link to their FAQ page which most people will have already tried.
If you want to sync with your desk top it can only be done via the cloud which is an additional bill on top of the annual fee. I changed to the note 10.1 and found it simply won't pick up the invoice style I sent them an e-mail asking for support and a week later still no response.
If you are a one man band and need a simple invoice that's professional looking and easy to track this is a good product but not the most competitively priced. If you are anything more than this look elseware, there are far better products better priced, the clunkiness and problems with across units means you will need the tech support which in my experience is worthless.
