Problem

Staff retype vendor, date, total, tax and currency.

Approved input

Approved receipt image

Bounded AI role

Extract five fields beside the source

Human checkpoint

Bookkeeper verifies every amount, category and duplicate

Failure path

Reject unreadable documents; never trigger payment

Data classification

Financial document; potentially sensitive

Measurement

Field accuracy; review minutes

Safe first test

Use synthetic receipts with blur, tax and currency variations

Move from a synthetic test to a reversible decision.

  1. Document the current manual path and baseline.
  2. Prepare the synthetic cases named above, including failures.
  3. Run the AI step without production writes or customer communication.
  4. Have the named reviewer compare every result with its source.
  5. Measure corrections, delay, exceptions, and reviewer effort.
  6. Keep, revise, or stop the test; retain the manual rollback path.

Before using this workflow

Should the workflow create a payment?

No. Extraction and payment approval are separate processes. The workflow must never trigger or release payment.

What data should be tested first?

Use synthetic receipts that include blur, tax, multiple currencies, duplicates, and unreadable fields.

What should the reviewer verify?

A bookkeeper should compare every proposed vendor, date, subtotal, tax, total, and currency value with the source.
