One-Click Payments enables you to make subsequent payments with one-click from an email reminder, without having to re-enter any account or payment details. 

The option will appear after you've made a successful payment.

To enable One-Click Payments, simply turn the feature on and select the day of the month you want to receive the reminder and the frequency of reminders you would like to receive. 

In the email reminder, there will be a link that you simply click on to make your payment. The payment details will be replicated from your most recent payment, however, you will be able to change these details (amount and pay method). 

The One-Click Payment feature is accessible once a payment is made on the confirmation/ approval page.
