I was using bootstrap on the site before. I kept tweaking it and realised I had to do a lot of tweaks to get it to a state I need. So I removed it in favour of custom design.
Thanks for the feedback. I'll style up the pricing page soon.
I just sent you an email about this but did you know that the design of your site is almost identical to what I just recently launched (https://writeapp.me - once you register an account and log in you'll definitely know what I mean). Colors, layout, buttons... errily similar. Honestly, definitely not saying you did it on purpose and even if it was on purpose I don't mind. In fact I'd be flattered! I'm just pretty amazed at how 2 different people came up with something so seriously similar.
Edit: I see you just signed up for an account (I get texts when new users sign up) so you probably never saw my design before which makes this even more awesome. By the way, I'm really diggin' CreateMyInvoice. Awesome work.
