Great, super easy to use. Liked it a lot. couple of suggestions:

1. White labeling - Let me get rid of the logo at the top and replace it with my own. Similar on the domain, maybe something like my_company.billmebob.com. Maybe these are things you could charge for.

2. Sign in - let me sign up after the first one and have it remember things like my company name, address, and maybe even companies I've billed before (I'm likely to do it again and don't want to repeat entering that all the time). Possibly something else you could charge for.

3. Recurring invoices - email the same invoice every month/week/etc. automatically. Probably need some kind of user account for that.
