Customers also buy

Related products are additional products or services offered together with a main product or service to increase the overall purchase value and meet customer needs. In BILLmanager, you can configure the display of related products in the customer's cart.

For example, for tariff plans of the "Dedicated server" product, the provider specified a domain name and the ispmanager control panel as related products. The customer buys a dedicated server. An offer to purchase the specified products will appear in the customer's cart.
Principle of operation of display conditions

How display conditions work

A related product is displayed if the conditions set for it are met. For details, see the section How to set up a display condition. 
Conditions can be combined into groups to create complex rules. If a Group of conditions is selected, the product will be displayed if at least one condition in the selected group is met. In the case of multiple groups — if at least one condition in each group is met.

Conditions are combined:

• within one group — using the OR operator. For example, there are conditions A, B, and C combined into one group. The product will be displayed if at least one condition from the group is met;
• among different groups — groups are combined using the AND operator. The product will be displayed if at least one condition from each group is met. For example, there are conditions A, B, and C combined into the first group, and conditions D and E combined into the second group. The resulting expression will be — (A OR B OR C) AND (D OR E). The product will be displayed if one condition from the first group and one condition from the second group are met.
