Offering the Try and Buy Mode with Alternative Billing Solutions

If you wish to offer the Try and Buy mode for Plesk with Presence
Builder and a custom billing solution, you should also carry out the
following operations:

1. Forward customers from Presence Builder to a custom store and save
   details about created sites.

   When a customer clicks to purchase a site, Presence Builder sends an
   HTTP POST request to a billing entry point. This request contains
   information about the customer and the created site. Business Manager
   (billing engine) uses this information to associate the site with the
   customer’s hosting account. To shift to a custom billing engine, you
   should change the billing entry point URL and extend your billing
   engine logic to save the POST parameters that come to the URL.

2. Ensure that customers purchase a hosting plan or add-on.

   This solely depends on the billing system and is beyond the scope of
   the CAS integration.

3. (For new customers only) Create a customer account, a subscription,
   and a site in Plesk.

4. Associate the site created in Presence Builder with an appropriate
   site in Plesk.

This appendix explains how to complete operations 1, 3, and 4.

How to Forward Customers to a Custom Entry Point

By default, the store entry point URL points to Business Manager. This
URL is stored in two placeholders (billingSignUpEntryPoint and
billingUpSellEntryPoint) in file tbbMessagesDefault.lng. The
location of this file depends on a Plesk installation directory (we
assume that you use the default one), server OS and architecture. Find
the file in one of the following directories:

• (On Microsoft Windows)
  C:Program FilesParallelssbresourceslocaleen_US or
  C:Program Files (x86)Parallelssbresourceslocaleen_US
  depending on the server architecture.
• (On RPM and DEB package-based Linux)
  /usr/local/sb/resources/locale/en_US

To customize the entry point URL, you should create a copy of the
tbbMessagesDefault.lng. file, name it tbbMessagesCustom.lng, and
modify the settings in the latter file.
