In Customer & Business Manager you can offer additional resources and services not included in service plans as add-on plans (or add-ons). Add-ons are listed together with plans on the Business Setup > Plans page. If a plan has add-ons, online stores show them on a separate store page, so customers are welcome to include add-ons into their order. The controls to attach add-ons to plans are available on the Add-ons tab of the plan settings page.
Typically, an add-on provides a single resource: disk space, traffic, or other resource defined for the panel group you select for the add-on. You are also free to offer multiple resources and services as a single add-on.
To let your customers choose an add-on from a list of similar add-ons, say, different amounts of additional disk space, add-ons are organized into groups. Moreover, it is mandatory for an add-on to have a related group. When buyers subscribes to a plan, they see the names of add-on groups you attached to this plan and lists of groups items - add-ons - you selected for the plan.
For example, this can look like the following:
Would you like additional disk space? (add-on group)
To see a list of plans with which you offer an add-on, go to the Plans tab of the add-on settings page.
Important: A service plan and attached add-on must have same billing cycles and currencies. Otherwise, customers will not be able to purchase this add-on.
In addition to offering hosting add-ons, you can sell SSL certificates using add-ons. For instructions on how to set up the SSL certificates selling through an add-on, see the section Adding SSL Certificates as Add-on to Hosting Plans.
Although it is possible to offer SSL certificates as independent plans, you can distribute them as hosting plan add-ons. Customers find it more convenient as the certificates are automatically installed to the domains they purchased. It is also attractive for you as Administrator because you will manage a single plan instead of two separate plans; it allows to cut down time costs.
To add an SSL certificate as an add-on to a hosting plan:
Important: To ensure the plans work well, add them to the same online stores, and set their pricing for the same billing cycles and currencies.
