Use the Try and Buy mode if you want your existing customers to create
trial sites even if Presence Builder is not provided with their license
or they have exceeded the number of sites they can publish.
To configure the mode, update the settings of your hosting plans. To do
that, open the settings and select the item Allow customer to create
trial Presence Builder websites. After you update the plan settings,
customers are able to launch Presence Builder by clicking the
corresponding link in the Customer Panel.
This feature is controlled on a per plan basis, so you can offer the Try
and Buy mode only for certain plans. If you deselect this item, your
customers will still see the buttons to launch Presence Builder but they
will not be able to actually launch it unless their plan includes
Presence Builder support.
Note: If the hosting plans you want to change are imported from Business
Manager and you want to keep them synced, go to the properties of
corresponding plans in Business Manager, make sure that the item
Allow up-selling Presence Builder sites is selected, and send
changes to Plesk by clicking Events > Run Events.
