The main difference between webhosting and reseller hosting is that you are unable to create other users with a webhosting package. You have only one account, with which you can login to DirectAdmin.
With reseller hosting, you can create other users and assign every user a certain amount of data traffic and disk space. The users you create can also login to DirectAdmin. In both cases, our services are 100% white label.
To get a good idea about the difference between normal webhosting and reseller hosting, please check the DirectAdmin demo, available at https://www.versio.uk/directadmin.
