Reseller hosting is where businesses sell website space to other businesses or individuals. The website reseller will buy a large amount of server storage space and bandwidth from a provider with data centers, like ourselves. This will be at a reduced 'wholesale' rate so that they're able to make a profit. They will sell this on as a package, including email.
Effectively, the reseller becomes the hosting provider to the third party. They will often brand themselves as such. Companies like 20i offer their resellers the option of re-branding control panels, known as 'white label' hosting.
Resellers will often become responsible for much of the administration of the business or individual's website. However, they may provide their customers with a control panel to make changes themselves. For example, our control panel for customers of resellers is called StackCP. This is its default name; it can be rebranded by the reseller.
