Can you give me a step by step process for setting up my clients domains?

1. Login to the WHM

2. In the left frame go to the section "Account Functions"

3. Click on "Create New account"

4. Specify domain, password, cpanel theme and other properties of the new account you'll see (ftp accounts, email account ,etc.) as you need them.

5. Click on the "Create" button in the right upper corner

If you check out the online documentation it also shows how to make various packages which have predefined disk spaces, bandwidth usage, email accounts, etc., so all you need to do is say which package you want to give a client and it automatically gives them all the correct amounts. This makes it much simpler.

I actually figured out a step, that is critical, but wasn't in your listing... first you need to create a package.... then when you follow your steps you select the package...

You are right.
Thank you for correction.
