The team at appInAll has been great to work with so far! They are always quick in responding when I need help or have questions about something they can't answer for me directly; it's not just one person looking over my shoulder but multiple people working on all different aspects of what i'm trying achieve - we're getting there!! It would be helpful if you could send them some screenshots/wireframes from your idea rather than using placeholder graphics etc., this helps us see exactly how everything will look like once its ready (a very important thing as well!). Also having someone who understands our business really helped speed up development time. We had an issue where part payment was going through without paying attention by ourselves which meant users were being charged twice even though only 1 transaction happened. This lead to 2 months worths fees before anyone spotted anything wrong, luckily we've got smart contracts now making sure transactions happen accurately every single day thanks guys :). Our client base grew quite quickly.
