Hi there, Currently developing a game server site, and need some advice when it comes down to the billing system. Also, I will be integrating with TcAdmin I have been told WHCMS, but read elseware it is very basic. Also I am considering Client Exec or ModernBill. However, I haven't used any before, but have good knowledge of PHP, etc so can get to grips with the system. Also the system would need to be easily integratable. All help with be appreciated, and rep will be left. James
