What to do
Determine whether the purchase-order reference is absent, unreadable, mislabelled, or missed by extraction. These are different exceptions. Do not fill the field using a nearby invoice number or a likely open order without separate supporting evidence.
Whether a PO is required depends on the destination workflow; extraction cannot establish that business rule.
Two worked review cases
These cases are fictional teaching data, not measured extraction results. Use the source excerpts to practise deciding what belongs in the reviewed output.
| Case | Fictional source excerpt | Review decision |
|---|---|---|
| Missed extraction | Source clearly shows Your PO: PO-22; output is N/A | Clarify the description or correct the reviewed staging value from the source. |
| Absent source | No purchase-order reference anywhere on the complete invoice | Route the missing-reference exception; do not invent a number. |
Suggested review columns
| Column | Definition or instruction |
|---|---|
| PO source status | Printed, absent, unreadable, or extraction missed it. |
| Raw reference text | Exact visible reference and its label. |
| Resolution evidence | Reviewer note or additional source needed to proceed. |
These are suggested staging-sheet columns. Printed facts can inform field descriptions in Parzable’s Schemas view; source references, review statuses, and decisions must be supplied by your own review process.
A practical review sequence
- Inspect all pages and labels such as Your order or Customer PO.
- Check the schema description distinguishes PO from invoice reference.
- Request authorized clarification when the destination requires a missing reference.
Errors to avoid
- Do not use the invoice identifier as a placeholder PO.
- A blank reference is not proof that the purchase was unauthorized.
Use the case worksheet with a small sample
Download this page’s worked-case worksheet. It contains the two fictional cases above and a blank row for your own review exercise. Keep any real source documents in your agreed storage process.
For the broader product workflow, see the related guide. Parzable accepts PDF/image inputs and downloads CSV. Suggested structures here are review targets; nested item rows, automatic approvals, and destination integrations are not guaranteed.
