This topic describes how to change the billing method of a cluster from pay-as-you-go to subscription based on your business requirements.


  • The cluster must be in the Running state.
  • No pending orders to change the billing method from pay-as-you-go to subscription. If pending orders exist, you must pay for or cancel these orders on the Orders page.


  • You cannot change the billing method of a cluster from subscription to pay-as-you-go. Consider your requirements before changing the billing method to subscription to avoid unnecessary resource usage.
  • Before you change the billing method, you must first upgrade the specification. If a cluster uses a specification that is no longer available, you cannot switch the billing method to subscription. For more information, see Change specifications.


  1. Log on to the PolarDB console.
  2. In the upper-left corner of the console, select the region in which the cluster that you want to manage is deployed.
  3. Find the cluster on the Clusters page and choose More > Switch to Subscription in the Actions column.
  4. On the Switch to Subscription page, check the cluster information, specify Purchase Plan, read and accept the terms of service, and then click Buy Now to complete the payment.
    • The new billing method takes effect after you complete the payment.
    • If the order is unpaid or the payment fails, an unfinished order appears on the Orders page. You cannot purchase a new cluster or change the billing method to subscription before you complete the payment.
