Billing Examples

DSC supports the yearly/monthly (prepaid) billing mode, and its APIs support the pay-per-use (postpaid) billing mode.

Billing Scenarios

A user purchased a DSC professional edition instance at 15:50:00 on May 1, 2023, together with a database expansion package and an OBS expansion package. The subscription duration is one month. After one month, the customer manually renewed the subscription for another month.

In June, the user needed to invoke watermarking APIs to watermark documents. The user invoked the API 1.1 million times from 2023/06/8 8:00:00 to 2023/06/28 18:00.

So, how much is the fee from May to June?

From 2023/05/01 15:50:00 to 2023/07/01 23:59:59, the yearly/monthly billing mode is used.

From 2023/06/8 8:00:00 to 2023/06/28 18:00, the billing mode is pay-per-use, and the number of API calls is 1.1 million.
