# Recurring payments and third-party approval

Some payment methods do not support asynchronous recurring payments.
In a recurring context, the customer must complete a payment at each cycle.
These payment methods may be more convenient for businesses that have longer cycles or one-time sales.

Payment cards, ACH/EFT/echeck, and PayPal accounts support recurring payments (rebills) and 1-click upsells.
Rebilly stores the payment instrument information in an encrypted vault.

Some payment methods require the customer to visit a third-party approval URL.
This may only at for the first transaction.

The following table describes some common payments scenarios.
