+1 to that. Also I wouldn't worry too much, their sites are noticeably less polished than Ronin. Also, there is a suspicious lack of company info, etc - a WHOIS

+1 to that. Also I wouldn't worry too much, their sites are noticeably less polished than Ronin. Also, there is a suspicious lack of company info, etc - a WHOIS on the domain returns a private registration which is strange for an invoicing business. Hearing that they develop in C# - or rather their offshore team in Pakistan does - does not fill me with confidence either. A lot of question marks. I wouldn't worry about it. Just ignore them.
