BILLmanager supports the option to configure special rules for switching to a specific tariff. Special rules have a higher priority over the tariff policy. If you change your tariff under special rules, a discount will be given for the new tariff.
You can configure special rules for each tariff in the Tariff change rules section. To go to the section, open Products → Tariff plans → select a tariff → click Change tariff.
The Tariff change rules section will be populated as tariffs are added to the product.
To configure a special rule:
- Enter Products → Tariff plans → select a tariff → click Change tariff →
- Select the tariff → click Rules → click Add.
- Fill in the form:
- Specify the order dates on which the special rule will apply.
- Select the order period.
- Specify the discount for the new tariff.
- Click Ok.
