Monthly Billing of a 12 month contract with extension of 12 month
We need to bill our customers per month with a contract of 12 (or 24 or 36) month runing time with extension of 12 month.
A customer has a contract of 12 month running time and the total costs are 1.200 € per year. But the customer needs to pay by month. Now we need to send the customer his invoices every month of 100 €. The contract has a running time of 12 month until the custumer cancel the contract. If the customer don't cancel the contract, the contract extends about 12 month.
