I instantly shunned it because it is advertised as hosted invoicing CMS. I know you can install it yourself, and this is where you should focus on too, like fusioninvoice, which I am very comfortable with at this time. No serious person is ever going to use your 'free-cloud-powered' service. As for paid cloud powered invoicing cms, freshbooks is a good choice, because I know they are not going to disappear overnight. But they are damn expensive for a small company therefore I use self-hosted fusion invoice cms.
