Billing

MTD supports the yearly/monthly billing mode. If you choose this mode, the longer you use, the more you save.

Billing Items

You are billed based on the purchased specifications, usage duration, and the volume of scanned logs that exceeds the specifications per month.

**Table 1** MTD billing
Billing Item	Description
(Mandatory) Edition	You are billed based on the package edition you choose, including Bronze, Silver, Gold, and Platinum packages.
Add-on package	If you finish the package quota, you will be billed based on the exceeding data volume on a pay-per-use basis. CAUTION: You do not need to buy add-on packages. The system automatically purchases an add-on package for you based on the volume of scanned data exceeding the package quota and charges you on a pay-per-use basis.
(Mandatory) Required duration	You will be billed on a yearly or monthly basis.

Billing Mode

In yearly/monthly mode, the longer you use, the more you save. You need to pay the bill for the required duration.

Renewal

Renew your subscription in time so we can keep MTD resources such as historical alarms for you. If you do not renew the service after it expires, MTD will charge you on a pay-per-use basis.

You can go to the management console to renew your subscription. For details, see Manual Renewal.

Expiration and Overdue Payment

Expiration
If you do not renew MTD after it expires, your resources will enter a retention period. The resources will be automatically deleted and cannot be restored and the service cannot be renewed after the retention period ends. For details about the retention period, see Resource Suspension and Release.

If the specifications you purchased expire and you do not renew them, MTD will charge you on a pay-per-use basis.
Overdue Payment
An add-on package may cause your account be in arrears.

If this happens, you can go to the Billing Center for detailed information. To repay the bill, see Making Repayments (Prepaid Direct Customers).
