Extract structured data from invoices — with page-level source grounding

Vendor details, line items, totals, and PO numbers — extracted as typed, auditable JSON. Every value carries a source citation and confidence score, so nothing reaches your enterprise resource planning (ERP) system or accounting system unreviewed.

GOVERNED EXTRACTION

Why not rely on LLM-only extraction for invoices?

LLMs can reason over an invoice — but accounts payable (AP) workflows need deterministic, auditable output grounded in the source file, not generated answers that vary between runs.

Output shape

LLM-only prompting

Generated answers that can change between runs.

Nutrient Data Extraction API

Predictable structured output — typed and tied to the source invoice.

Routing signal

LLM-only prompting

No signal for which values to trust.

Nutrient Data Extraction API

Confidence signals route uncertain values to human review before payment approval or ERP sync.

Traceability

LLM-only prompting

No way to point back at the page.

Nutrient Data Extraction API

Coordinates and page references anchor every value to its source location.

Line items

LLM-only prompting

Tables flattened into unstructured text.

Nutrient Data Extraction API

Layout-aware structure preserves line-item tables with row and column context.

Review step

LLM-only prompting

Values reach downstream systems unchecked.

Nutrient Data Extraction API

Human review and validation before matching logic, ERP, or payment systems.

Audit

LLM-only prompting

Nothing to show an auditor.

Nutrient Data Extraction API

Source context and page detail support traceable, audit-ready accounts payable workflows.

HOW IT WORKS

From invoice to structured output

Parse

Turn invoice PDFs, scans, images, and Office files into document structure.

Extract

Identify line-item tables, key-value regions, totals, and dates.

Map

Define the fields your workflow needs using the schema generator in Studio, or write a JSON Schema directly. Get back validated, typed output.

Structure

Return typed JSON for systems and validation, or Markdown for search and AI workflows.

Process

Send structured data into AP review queues, matching logic, or ERP and accounting systems.

OUTPUT FORMATS

Spatial JSON. Or Markdown. From the same API.

Confidence scores, coordinates, and page context included.
Choose output: "json" or Markdown per request.

ACCURACY

Benchmarked accuracy, invoice-specific numbers in progress

Invoice-specific accuracy benchmarks are still being validated against a public gold-annotated dataset. In the meantime, the general Data Extraction API benchmark — reading order, table structure, and heading hierarchy, tested on a 200-document corpus with every release — is the current accuracy proof.

Invoice data extraction questions

Can the API extract line items from invoice tables?

Yes. The API identifies table structure — rows, columns, and cells — from invoice line-item tables, with confidence scores and source coordinates per cell so line items can be validated before entering downstream systems.

What file formats are supported?

Data Extraction API processes PDFs, scanned documents, images, Word, Excel, and PowerPoint files. It handles scanned invoices, faxed invoices, and mixed digital/image-based documents without requiring a separate OCR pipeline.

Is this an accounts payable automation platform?

No. Nutrient Data Extraction API is an extraction layer, not an AP automation suite. It turns invoices into structured, typed data so that data can be reviewed, matched, and routed into the AP or ERP system your team already uses.

How do I validate extracted invoice data before it enters my ERP?

Every extracted field includes a match label, confidence score, page reference, and bounding box, so uncertain fields can be flagged for human review and traced back to the source invoice before entering payment approval or ERP sync.

How do I define the invoice fields to extract?

Use the schema generator in Studio — upload example invoices and describe the fields needed. It generates a JSON Schema for the `/extract` endpoint. Fields like invoice number, vendor, line items, and totals can also be defined manually. Refer to the documentation for supported field types and limits.

When should I use agentic mode for invoices?

Use agentic mode for degraded scans, faxed invoices, and handwritten annotations where understand mode produces insufficient results. Agentic mode adds a vision language model (VLM) on top of the understand pipeline. It costs 18 credits per page.
