M2 Custom Tariffs
Custom Tariff Rates have a higher priority than regular Tariff Rates. For example, if an Origination Point has both Tariff and Custom Tariff and some Rate prefixes match between those Tariffs, the specific Rates of Custom Tariff will be applied and shown to the End User.
Management of Custom Tariff is pretty similar to regular Tariffs' management. It is accessible by Admin and Manager with Custom Tariff Permission rights.
To apply Custom Tariff for Connection Point go to its settings (edit page) Origination Point section and choose Custom Tariff from dropdown.
