This is everything that you need to know regarding overdue invoices.
If an invoice is overdue for more than 3 days, your station will be suspended. After an invoice is overdue for 10 days, your station will be terminated. After 60 days of an overdue invoice, your account will be deleted. If you are looking for information on Cancellation and Reactivation, you can find that here.
Live365 offers 3 extensions of the invoice due date per year. After 3 extensions, the above policy will apply.
You can find further information about your billing cycle, due dates, invoices, making payments, upgrading, and canceling your station here.
