Read Cost Management material while deciding what actually rates usage. It was useful as the place customers already see Marketplace lines, but it does not apply a vendor tariff to custom counters.
- What worked
- Docs quickly separated display of Microsoft-rated charges from the service that turns usage events into amounts owed.
- What got in the way
- It is not a rating engine for per-device and per-megabyte meters, so it could not be the component that generates charges from ingest aggregates.
