Leaves several station-level fields null—address, city, state, postal_code, main_phone, and billing_phone—even though the station block is present in the schema and related info exists elsewhere in the invoice.
What was measured
Extraction Accuracy
Are field values correct, complete, and free of OCR or parsing errors, including numerical precision on financial fields?
decisive for this rankingtransformation
Correct field values are the core of the job; wrong or incomplete extraction means the tool failed to retrieve the structured data from the document. (3 of 3 judges)
What was given, what came back
Test input: Invoice PDF · pdf · group: business-document-extraction
Input — what we sent
A two-page broadcast advertising invoice PDF with nested header metadata, billing and remit addresses, and eight line items spanning a page break. It was used to stress hierarchical line-item extraction, amount precision, time/day parsing, code extraction, and summary validation.
Why this input is hard
- · Nested line-item hierarchy extraction
- · Multi-page continuity across a page break
- · Precision on large dollar amounts and totals
- · Parsing complex time slots and day patterns
- · Extraction of Ad IDs and reconciliation codes
- · Mapping structured metadata sections correctly
- · Financial summary validation
- · Handling political advertising compliance text
Output — unretouched

Schema Adherence✓ WorkedReconstructs the invoice hierarchy into invoice_metadata, advertiser, station, billing_address, remit_address, flight_dates, line_items, and summary objects rather than returning flat OCR text.Semantic Field Enrichment✓ WorkedPopulates derived scheduling fields such as day_of_week "M" and days_pattern "MTWT" on invoice line items.Structural Clean Output✓ WorkedReturns directly consumable JSON for the invoice workflow, with the demo reaching extracted results and the report stating the JSON is immediately usable for integration.Table & Record Completeness✓ WorkedExtracts all 8 advertising line items as separate records, preserving the page-break continuation instead of merging or omitting rows.

Datalab✓ WorkedRecovers invoice metadata and financial totals accurately: invoice number 4064621-1, invoice date 10/28/12, gross total 29750, agency commission 4462.5, net amount due 25287.5, and 8 aired spots match the source.Docsumo✗ FailedThe Advertiser Code field is cross-contaminated with an unrelated field label/value: it should be 155, but the extracted cell shows Net Amount Due instead.Extend AI✗ FailedIt over-reads the payment-term field, outputting `Payment Terms 30 Days` instead of the requested `30 Days`.LlamaParse✓ WorkedThe invoice totals and headline metadata are extracted consistently: aired_spots is 8, gross_total 29750, agency_commission 4462.5, net_amount_due 25287.5, and payment_terms 30 Days match the source invoice.Nanonets✓ WorkedExtracts invoice and finance values accurately, including invoice number 4064621-1 and summary totals of 8 aired spots, 29750 gross, 4462.5 commission, and 25287.5 net amount due.Reducto✓ WorkedMatches the invoice's financial values in the summary, including aired_spots, gross_total, agency_commission, and net_amount_due, with the report stating the summary matches the source document.Retab◐ MixedRetains the source label in payment_terms, returning 'Payment Terms 30 Days' instead of only the requested value, so the field is not fully normalized.Unstract✓ WorkedCaptures the invoice header fields and financial totals exactly, including invoice_number 4064621-1 and the printed gross_total 29,750.00, agency_commission 4,462.50, and net_amount_due 25,287.50.
