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


  • Your cluster is in the Running state.
  • The subscription billing method is used for the cluster.
  • The cluster is not in the temporary upgrade state.
  • Make sure that your account balance is sufficient to avoid service downtime that is caused by overdue payments after you switch the billing method to pay-as-you-go.


After you switch the billing method of the cluster from subscription to pay-as-you-go, a subscription refund can be returned to your original payment account.

Refund = (Number of remaining days/Total days) × Order cash amount.

Note The order cash amount indicates the actual paid amount that excludes vouchers or coupons.

  1. Log on to the PolarDB console.
  2. On the top of the page, select the region where the target cluster is located.
  3. Find the cluster for which you want to switch the billing method, and choose More > Switch to Pay-as-you-go in the Actions column.
  4. On the Switch to Pay-As-You-Go page, confirm the cluster information. Then, read the terms of the service agreement, select the check box, and click Buy Now.
    • The new billing method takes effect after you pay for the order.
    • If the order is unpaid or the payment fails, an unfinished order appears on the Orders page. You cannot purchase a new cluster or switch the billing method to pay-as-you-go because of the unfinished order. In this case, you must pay for or cancel this order.
