Creating tariffs is the first step in creating client accounts, as tariffs and rates must exist before assigning accounts a tariff. There are two ways to add tariffs: new, which allows adding a clean tariff without rates, or copy, which creates a tariff based on an existing one. Rates can be imported from a CSV file by selecting the file and clicking import. Rates can also be exported to a CSV file by selecting the file separator and clicking start then download. Rates can be modified using the change rates button to set a new rate, change a rate by value or percent.
