I didn't post this, but I am the author. Thanks for all the kind words on the post.
As far as Float goes, it currently only works with www.freeagent.com, so if you are a FreeAgent user, feel free to sign up.
I am (as we speak) working on integration with www.xero.com, and there's more detail on that here if you want to try the beta: http://floatapp.com/xero.
All thoughts and feedback on either the post of the product are more than welcome :)
Thanks! Phil
I am probably in a position similar to yours 2 years ago: I am working and learning to code on the side.
Could I ask you how did you get the integration with xero and freeagent? I am working on an app too (vendors and orders management) and I keep wondering how to reach out potential customers.
FreeAgent and our customers have mentioned us on twitter/blogged about us sporadically over the last couple of years.
Don't just wait. We are still working on our Xero integration (I only really started on it last week), and I stuck up http://floatapp.com/xero so we could collect emails of people who wanted to try the beta, and we've got ~70 replies (mostly from accountants) by sharing it on twitter/facebook/linked in/Xero's support forums.
