Key takeaways
- Supplier document validation checks what a supplier sent against what your ERP says: the agreed price, the ordered quantity, the received goods and the quality specification.
- Document AI reads each page with intelligent character recognition and returns structured output that matches the schema you define, with no templates, no labeling and no model training.
- Four document families share one pattern: contracts and price lists, purchase orders and confirmations, invoices, and certificates of analysis.
- Rebates and trade-promotion deductions add a judgment step: the extractor reads the claim, and a rule or a person decides whether it matches the agreement.
Your ERP is right, and the documents do not agree with it
Your ERP holds the agreed prices, the open orders and the goods you received. The suppliers send PDFs, scans, spreadsheets and emails that should match those records, and your accounts payable, procurement and quality teams check them by hand.
