Yes, you can! A Cpanel/WHM reseller account can be set up in a number of different ways. However, we do allow you to create your own plan sizes and pricing, so you aren't restricted in how you offer your product to your customers. With the use of the 'packages' feature in WHM or the Products/Services feature in WHMCS, you can create plans of any size (as long as it is within the boundaries of your account limits) with ease.
