You can set up recurring billing on your website with PayPal Checkout and Website Payments Pro. Both PayPal Checkout and Websites Payments Pro require a developer with API programming ability.

If you offer PayPal Checkout and recurring payments, customers can pay with their PayPal account. If you offer Websites Payments Pro and recurring payments, your customers can pay without a PayPal account, using their debit or credit card.

For more information, visit our  PayPal Developer  website. 

Alternatively, you can create a Subscribe button for a quick way to accept subscription-type payments on your website. You can use the Subscribe button to bill customers on a regular basis, charge membership fees, or offer subscription services. We provide the HTML code which you copy and paste into your website's code.

The main differences between a subscription and recurring billing are:

• Recurring Payments integrate with PayPal via APIs. Subscriptions integrate with PayPal via HTML. 
• Recurring Payments allow your customers to checkout at cart level with multiple items. Subscriptions allow your buyers to complete their purchase for one item or service at a time.
• Recurring Payments support merchant management, including limited modification, suspension/reactivation, and billing on an outstanding amount.
