Just launched Fluttervoice. 'Flutter' as in paper (or invoice) fluttering in the wind or whatever, and 'voice' as in invoice. Fluttervoice.
Heavily inspired by 37Signals et al of course. Started writing it last year March. Became extremely busy with other Rails work. Then became lazy. And despondent. Then more despondent as more and more invoicing apps started sprouting all over the place. Then the admin of setting up a company and bank accounts and all that confusing stuff. Then more client Rails work. Then a design. Then a redesign. And final touches. And SSL etc. Anyway - it's been a long long time but it's finished now. All of it works except for two things: You cannot subscribe to the paid plans yet, and therefore you also cannot cancel your account yet. But we are hoping to finish all the payment gateway work (so that you can subscribe to the paid plans too if you need to) in the coming week. We hope you enjoy using Fluttervoice!!
