# Modify subscriptions

Change existing subscriptions to cancel, pause, apply prorated charges and credits, and more.

You can change existing subscriptions without having to cancel and recreate them. Set up the [customer portal](https://docs.stripe.com/customer-management.md) to let your customers manage their own subscriptions and billing details through a Stripe-hosted page.

For changes that automatically create a new [subscription invoice](https://docs.stripe.com/billing/invoices/subscription.md), use [pending updates](https://docs.stripe.com/billing/subscriptions/pending-updates.md) so that the updates are only applied if the new invoice is successfully paid.
