Data Transmission Service (DTS) charges based on the feature you use and how you run it. This page summarizes what you pay for, the available billing methods, and how to manage your bills.
Pricing by feature
The three DTS features — data migration, data synchronization, and change tracking — follow different billing rules. The table below shows what each feature charges for and which billing methods it supports.
| Feature | Billing methods | Charges |
|---|---|---|
| Data migration | Pay-as-you-go only | Instance configuration fees (only during incremental data migration) + Internet traffic fees |
| Data synchronization | Subscription, pay-as-you-go | Instance configuration fees only |
| Change tracking | Subscription, pay-as-you-go | Instance configuration fees + data transfer fees + Internet traffic fees |
For data migration, instance configuration fees apply only while incremental data migration is running.
For exact prices, see Data Transmission Service Pricing.
Billable items
DTS charges for up to three item types, depending on the feature:
Instance configuration fees: charged based on the instance specification you select.
Internet traffic fees: charged for data transferred over the public internet.
Data transfer fees: charged for the volume of data consumed by change tracking subscribers.
For the full breakdown of how each item is calculated, see Billable items.
Billing methods
DTS supports two billing methods:
Subscription: pay upfront for a fixed term. Suitable for long-running synchronization or change tracking tasks where usage is predictable.
Pay-as-you-go: pay for what you use. Suitable for short-term migrations or unpredictable workloads. This is the only option for data migration.
For details on how each method works, see Billing methods.

Instance renewal and refunds

Before canceling a subscription instance, read the refund rules carefully. See Refund policy.
