How metering works

1

One unit per assessment

Each assessment DCS processes (ROM, dexterity, …) is one billable unit, reported to Stripe the moment it completes.

2

Included volume first

Your plan's monthly allotment is included in the base price. You only pay overage once you exceed it.

3

Metered overage, billed monthly

Usage above the allotment is metered at your plan's per-assessment rate and added to your monthly Stripe invoice.
