Thank you for the reply!
I actually am not wondering if I should use projects... I am going to set it up.
I am trying to figure out what the cons are of converting sub-customers into projects, since those are already set up. There are several ways to set up projects, but I do remember seeing something that said not to convert subcustomers to set up projects but I am not sure why.
I need to find someone that has expirence with why I would or would not want to "mass convert" sub-customers to make them projects.
