Confirm a physical build without double-deducting
How confirmed builds deduct components exactly once, and what happens if you cancel or reverse a build.
4 min read

- 1
Launch a build from Make Product or a method workspace; the job holds a snapshot of the cost-to-make lines to use.
- 2
When you confirm the physical build, each stock component is deducted once and marked as deducted.
- 3
A repeat of the same confirm request is ignored via an idempotency key, so stock never doubles up.
- 4
Cancelling or reversing a build returns materials to stock with a reversal transaction, keeping history complete.
What happens next
Finished-stock count rises and the build is recorded with its actual costs. You can invoice from there.
