Opsbilling reviews
 

Their support suck, you have to wait for 1~2 days to get responses from them, they even didn't some time.

Their software is stupid , It removes customer's web access immediately the whos just cancelled but membership not expire.

Weak security, try this to see what happen if you are using opsbilling?

yoursite.com/cgi-bin/adduser.cgi?command=ADD&username=1234&password=123 4

also opsbilling declined a few valid cards...

I think I will drop them soon...

my :2 cents:

maybe you shouldn't be posting security flaws on the message board
