License contracts, invoices, reports, forms and other business documents for document AI and agent training, with redaction and rights checks done first.

## Summary

- Document AI models learn to read layouts, tables, signatures and fields from real business documents.
- The most useful datasets pair the original file with its extracted fields, which shows a model what the right answer is.
- Documents almost always contain counterparties' information, so confidentiality clauses and redaction come before licensing.
- Scanned and messy documents are often worth more than clean ones, because they are what models struggle with.

## Specification

| Field | Detail |
| --- | --- |
| What it is | PDFs, scans and office files such as contracts, invoices, purchase orders, statements, applications and reports, ideally with extracted field values. |
| Measured in | Documents and pages, by document type and layout variety. |
| Who buys | Document AI vendors, labs training multimodal models, agent builders automating back-office work. |
| Where it comes from | Shared drives, document management systems, accounts payable archives, legal and insurance files. |
| Rights to clear | Counterparty confidentiality, NDAs, client ownership of deliverables and any regulatory record-keeping rules. |
| Privacy | Names, addresses, account numbers, signatures and IDs redacted or replaced. Financial account numbers removed entirely. |
| Pricing signal | Priced on document count, variety and whether ground-truth labels are included. |

## What makes document data valuable

Variety beats volume. A model that has seen 5,000 invoice layouts from 3,000 suppliers learns more than one that has seen a million invoices from one template. Buyers also value the hard cases: faded scans, handwriting, stamps, rotated pages, multi-page tables.

## Labels multiply the value

If your systems already extracted fields from each document, such as invoice totals entered into an accounting system, that pairing is ground truth a model can learn from. Keep the link between file and fields when you prepare the data.

## Rights and confidentiality

Business documents are full of other parties' information. Before licensing:

- Check NDAs and contract confidentiality clauses with counterparties
- Exclude documents that belong to clients, such as deliverables you created for them, unless the contract allows it
- Exclude regulated records with their own rules, such as health or credit records
- Remove or replace financial account numbers, tax IDs and signatures

## Formats buyers accept

Original PDFs or images plus a JSON or CSV file of extracted fields per document, with a manifest listing document type, date range and source system. See [how to build a data manifest](https://aidataforsale.com/learn/how-to-build-a-data-manifest).

## Questions

### Can we license invoices we received from suppliers?

Possibly, after checking supplier agreements for confidentiality terms and removing account numbers and personal details. Many companies license only the extracted, de-identified version.

### Are templates worth anything?

Blank templates have little value. Completed, varied, real documents are what buyers want.

### Do buyers need the original files?

For document AI, yes. Layout is part of what the model learns, so text-only extracts lose much of the value.
