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.

Prerequisites

  • 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.

Pricing

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.

    Note
    • 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.
