If you are a web design agency or have clients that are interested
in buying hosting solutions then you may want to purchase a reseller
web hsoting account.
This allows you to pay a set monthly fee and give your clients
a tailor made solution aroud their requirements. For example,
some of your clients may not want too many email addresses but
require lots of space whereas others may require WordPress hosting.
Reselling web hosting means that you can often white label these
services as your own and offer this as either a standalone service
or as part of an integrated solution.
