How is TencentDB for SQL Server priced?
TencentDB for SQL Server comes with a genuine Microsoft license and can be billed in a pay-as-you-go (postpaid) manner.
The price consists of two parts: instance specification (memory capacity) and storage space (disk capacity). For pricing details for different regions, please see Product Pricing.
How do I purchase a TencentDB for SQL Server instance?
Log in to the TencentDB for SQL Server Console to create an instance or purchase an instance directly on the purchase page.
Do I have to buy an SQL Server license?
Tencent Cloud can provide TencentDB instances with "license included". The price of a "license included" model includes a SQL Server software license, underlying hardware resources, and TencentDB management features, so you don't need to purchase a Microsoft SQL Server license separately.
With a "license included" database, you only need to pay for instance specifications and usage duration and don't have to worry about hardware and licensing costs. Therefore, you only pay low variable costs instead of high fixed costs, which helps you reduce IT costs.
Note：
Purchasing TencentDB for SQL Server does not mean that you purchased a Microsoft SQL Server long-term license contract; therefore, you should not use the TencentDB license outside of this service. For more information, please see Microsoft Volume Licensing Product Terms and Online Services Terms.
The basic price of TencentDB for SQL Server does not include other Microsoft or Tencent Cloud services.

Billing mode switching from pay-as-you-go to monthly subscription for TencentDB does not support the 5-day unconditional refund.
In cases of suspected abnormal/malicious returns, Tencent Cloud reserves the right to refuse your return request.
Before requesting a refund, view the refund instructions and notes, see Refund.
What Happens If TencentDB for SQL Server Expires with Arrears?
For monthly subscription instances:
The system will send users a renewal reminder notification via email, on-site messages, and SMS 7 days before the expiration of TencentDB resources.
If your cloud service is not renewed before it expires (including the day of expiry), the system will start to suspend the service (cutting off the network and shutting down devices, while only retaining the data) at the point of expiry.
TencentDB resources that have expired for more than seven days will be reclaimed by the system, and the data will be cleared and cannot be recovered.
For pay-as-you-go instances:
From the moment the balance becomes negative: Within 24 hours, TencentDB can continue to be used and fees will continue to be charged. After 24 hours, the TencentDB instance will be isolated, and the isolated instance cannot be accessed, while billing is stopped.
After automatic shutdown: Within 3 days of shutting down, if your account balance is not topped up to more than 0, you cannot start it. If the balance is topped up to more than 0, billing will continue, and you can start it. If the account balance is less than 0 for 3 days, the pay-as-you-go TencentDB will be reclaimed, all data will be cleared, and cannot be retrieved.
For more details, see Payment Overdue.
What Are the Differences Between Monthly Subscription and Pay-as-You-Go Billing Modes?
Monthly subscription: Also known as prepaid, where you pay for the instance when creating it. Suitable for long-term needs, more cost-effective than pay-as-you-go. The longer the purchase duration, the more discounts available. Monthly subscription instances cannot be changed to pay-as-you-go instances.
Pay-as-you-go: Also known as postpaid, where a charging order is generated every hour, and fees are deducted from the Tencent Cloud account according to the instance specifications at the time the order is created. Suitable for short-term needs. The instance can be released immediately after use, saving costs. Pay-as-you-go can be converted to a monthly subscription. For more details, see From Pay-as-You-Go to Monthly Subscription.

Purchase instances in another availability zone within the same region, and once the target availability zone is restocked, migrate the instance to the target zone. For detailed steps, see Migrating Across AZs. Instances in different availability zones within the same region can interconnect over the private network, which will not affect your use, so this method is recommended.
If your business needs are not urgent, wait for some time. Once the target availability zone has instance stock available, proceed with the purchase. However, due to varying conditions across supply chains, the time required to replenish stock cannot be determined.
