Billing

Enterprise routers are free of charge. If you create attachments to an enterprise router, you will be charged for attachments and the amount of traffic flowing through the attachments. For details, see Table 1.

You can use an enterprise router to connect different types of attachments, including VPC, virtual gateway, and VPN gateway. In addition, an enterprise router can connect attachments from different accounts.

**Table 1** Enterprise router billing items
Billing Item	Attachment Type	Description
Attachment	VPC Virtual gateway VPN gateway	Hourly billing starts when an attachment is created and stops when the attachment is deleted. If an attachment is created to a shared enterprise router, hourly billing starts when the enterprise router owner accepts the attachment. An attachment of an enterprise router is billed hourly and only in full hours. If the usage duration is less than one hour, the attachment is still billed for a full hour. The following uses a VPC attachment as an example. Scenario 1: You added a VPC attachment to an enterprise router at 12:36 on July 6, 2022 and deleted the attachment at 12:57 on July 6, 2022. In this case, you need to pay for a full hour. Scenario 2: You added a VPC attachment to an enterprise router at 12:59 on July 6, 2022 and deleted the attachment at 13:01 on July 6, 2022. In this case, your usage spanned 2 clock hours, so you need to pay for 2 full hours. The price of different types of attachments is subject to that displayed on the console.
Traffic	VPC Virtual gateway VPN gateway	The amount of traffic flows from an attachment to an enterprise router (inbound traffic) is billed. The price of traffic per GB is subject to that displayed on the console.

An attachment creator pays for its attachment and used traffic.

For example, if a shared enterprise router has VPC attachments from its owner and other accounts. If the owner creates attachments to the enterprise router, the owner pays for the attachments and used traffic. If the other accounts create attachments to the enterprise router, these accounts pay for the attachments and used traffic.
