Initiate a monthly automatic bill
For Automatic Billing buttons, PayPal does not collect payments from buyers until you initiate a monthly bill. When you know the amount you want to bill a customer each month, you need to initiate a billing request to collect the payment. After you initiate the bill, PayPal collects the payment automatically. You can only bill a customer once in any monthly billing cycle.
