Differences between the subscription and pay-as-you-go billing methods
Subscription: You can use services only after you have paid for them. If you select this billing method, you must purchase a resource plan before you can use the relevant service.
Assume that you have purchased a resource plan for a specific service. After you use up the quota of the resource plan, the excess resource usage is billed in pay-as-you-go mode.
Pay-as-you-go: By default, you are billed in pay-as-you-go mode after you activate a speech service in Commercial Edition by using your Alibaba Cloud account.
In pay-as-you-go mode, your consumption on the current day is billed on the next day. Make sure that your account balance is sufficient. If your bill is overdue for a specific amount, the relevant service is suspended and Alibaba Cloud sends you a notification.
