# How it works?

### Subscription without auto-renewal

If you select the [EXPIRE AFTER](/product-setup/product-expiration.md) option in the product editor, then **subscriptions are not auto-renewed**.

**Customer must manually pay** for subscription expiration date to be extended.

If the expiration date is exceeded, the expiration actions you configured will be executed.

### Recurring subscription

Your subscribers will be automatically charged each cycle.

**Example:** If the customer subscribes on January 15 and you have configured the cycle for 1 month, then it will be debited on January 15, then February 15, then March 15, etc.

<summary>What happens if a recurring payment fails?</summary>

If the payment fails, it is retried a few days later. If it fails again, then the subscription is canceled and the expiration commands are executed. You can configure it from [My Gateway](https://tip4serv.com/dashboard/my-gateway).

<summary>What happens if the customer unsubscribes?</summary>

If the customer cancels his subscription, the expiration actions you have configured in the product editor will be executed at the end of the current cycle.

**Example for a subscription with a 1-month cycle:** the customer subscribes on January 15 and then cancels his subscription, expiry commands will be executed on February 15.
