# Make a Payment to Subscription

A two-step process, which allows you to first define the invoice being paid and then perform the payment. The **Make Payment** action is enabled when a due or overdue invoice is associated with the Subscription.

For an existing subscription, you can apply a payment to the subscription by clicking the **Make Payment** button that appears in the **Actions** panel.

Payments are accepted for subscriptions with outstanding balances only when invoices issued for the Subscription are due or overdue.
