Extracts the invoice summary totals correctly, including agency_commission 4462.5, aired_spots 8, gross_total 29750, and net_amount_due 25287.5.
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

Schema Adherence✓ WorkedReconstructs the invoice schema into nested invoice_metadata, advertiser, station, account_details, billing_address, remit_address, flight_dates, line_items, and summary sections rather than returning a flat document dump.Semantic Field Enrichment✓ WorkedDerives scheduling fields from the line item, including day_of_week 'Su', days_pattern '------S', air_time '09:38:00', and time_slot '9a-10a'.Structural Clean Output⚠ StruggledPreserves valid JSON but does not keep the schema's original key order, so downstream consumers that expect schema-consistent ordering need an extra formatting step.Table & Record Completeness✓ WorkedExtracts all 8 advertising line items as separate structured records without duplication or omission.

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 Remit Address repeats the Station address block instead of extracting a distinct remit location, and the Flight Dates field merges the date range into one string while leaving the end date empty.Extend AI✗ FailedIt over-reads the payment-term field, outputting `Payment Terms 30 Days` instead of the requested `30 Days`.Landing AI✗ FailedMisreads at least one alphanumeric identifier: line 1's source Ad-ID NRCCWI071005 is extracted as NRCCW1071005.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.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.
