Estimated Credits vs Final Credit Usage
DocPurify handles credits in three steps: estimate before start, lock at queue entry, and final settlement after completion.
Status & Scope
Current status: Live. This guide focuses on setup, what is available now, and the current limits.
Estimated credits help you decide whether to start processing. Final usage is based on the actual amount of work after the job finishes.
Credit flow
- Estimate: before processing starts, the system calculates estimated credits from the file and selected options.
- Lock: when the task enters the queue, part of your credits is temporarily locked.
- Settle: after the task completes, actual usage is calculated and any difference is adjusted.
How differences are handled
- If final usage is lower than the locked amount, the extra locked credits are returned.
- If final usage matches the locked amount, settlement finishes directly.
- If final usage is higher than the locked amount, the system deducts the difference.
Note
Failed or cancelled tasks may follow different settlement paths, so use the final transaction record as the source of truth.
FAQ
Why is final usage different from estimate?
The estimate is shown before processing starts, while final usage reflects the actual amount of completed work.
Should I show estimate or final usage to my team?
Use the estimate before starting a task, and use final usage for settlement or reporting afterward.
