Please follow below steps to create accounts for your clients in WHM.
1) Login to WHM
2) Create package by cliking on "Create new package" link in packages category.
While creating packages do not put "UNLIMITED" in any feature field box as WHM treats "UNLIMITED"= 1. You may face some problems in future if you put "UNLIMITED". Hence Always assign some reasonable number say 999 or 9999 for UNLIMITED.
3) Then click on "Create New Account" in Account Functions Category. Enter domain name , user name and password. Then select package you want to assosiate with particular account and hit "Create" button.
Please wait until you see message "Account creation completed"
That's it..

you are now ready to use newly created account.
Note: You need to update newley created domain DNS to your reseller account servers. It means your reseller domain and all your clients domains points to same name server.
After DNS propagation you can access newly created domain cPanel just like your domain.
http://www.domain.com/cpanel or
https://www.domain.com:2083Replace # with your server number which can be found in your reseller username.
Hope this helps you
