When you create a new radio station you can select the plan that best suits your needs.
In case you select a month by month charge, you will be charged the price of your plan for the month ahead.
In case you select the yearly plan, you will be charged the price of your plan for the year ahead.
To see your station's plan, invoices & balance, as well as the option to change your plan or even deactivate your station, navigate to the the Billing section of your Station's page.
You can change your current plan or billing cycle by clicking on the "Change plan" option, as shown below.
