An AC acct lets you create campaigns within it, and each campaign can have its own credit card. So, yes, you could have five clients on one acct. However, if you give a client an access to the acct, the client can see all of the other clients.

Ask whatever you like; we've been using this for several months. It works quite well. It has a number of features that are better than the other PPC tools. You'll find that you'll use both Google and MSN adCenter.
