# Purchase Order Parser -- Emailed PDF POs to Structured ERP Data | DigiParser Source: https://www.digiparser.com/solutions/purchase-order-parser [Home](/) [Solutions](/solutions) Purchase Order Parser Last updated: May 2026 - Published by [DigiParser](/) Procurement & IDP # Purchase Order Parser -- Emailed PDF POs to Structured ERP Data When **every supplier formats POs differently**, companies use **intelligent document processing (IDP)** -- not template-only OCR. Emailed PDF attachments are ingested, layout and line items are extracted to JSON, business rules validate totals and master data, exceptions go to a review queue, and approved POs post to **SAP, NetSuite, Dynamics, or Odoo**. DigiParser handles variable supplier layouts without coordinate templates per vendor.

They use intelligent document processing (IDP): email ingestion -> OCR and layout analysis -> AI extraction to JSON (PO number, supplier, line items) -> validation rules -> human review for low-confidence fields -> ERP import. DigiParser handles variable supplier layouts without maintaining coordinate templates per vendor, and connects to SAP, NetSuite, Dynamics, and others via API, CSV, or Zapier. ### What types of purchase orders can you process? We process all PO formats including standard purchase orders, blanket POs, contract POs, planned POs, and change orders. Our AI works with PDFs, Word documents, Excel spreadsheets, email attachments, EDI messages, and scanned documents from any vendor or procurement system. ### Can you extract line items with multiple products? Yes! We excel at extracting complex line item tables including product descriptions, SKUs, quantities, unit prices, discounts, taxes, and line totals. We can handle POs with dozens or hundreds of line items, and maintain proper structure even across multiple pages. ### How accurate is the PO data extraction? We achieve 99.7% accuracy on purchase order extraction. Our AI is trained on millions of POs from various industries, ERP systems, and vendors. The system handles different layouts, custom fields, and international formats with high precision. ### Do you support 3-way matching? Yes! We can automatically match purchase orders with invoices and delivery receipts (goods received notes). The system compares quantities, prices, and descriptions to identify discrepancies and flag potential issues for review before payment. ### Can you integrate with our ERP system? Yes! We integrate with major ERP and procurement systems including SAP, Oracle, NetSuite, Microsoft Dynamics, Sage, Epicor, and more. We also support e-procurement platforms like Coupa, Ariba, and Jaggaer. For custom systems, we provide RESTful APIs and webhooks. ### How fast can you process purchase orders? Single-page POs are processed in 5-8 seconds. Multi-page POs with extensive line items typically complete in 10-15 seconds. For bulk processing of hundreds of POs, we use parallel processing to handle high volumes efficiently. ### Can you handle international purchase orders? Absolutely! We process POs in any language, currency, and format. Our system recognizes international address formats, various date conventions, and multiple currency codes. We can also handle Incoterms and international shipping terms. ### Is purchase order data secure? Yes. We use 256-bit encryption, maintain SOC 2 Type II certification, and comply with data protection regulations globally. Procurement data is processed securely and can be automatically deleted per your retention policy. We never share vendor or pricing information. ### Can you detect duplicate purchase orders? Yes! Our duplicate detection algorithms compare new POs against historical records using PO numbers, vendor details, items, amounts, and dates. This prevents duplicate orders, over-ordering, and potential fraud. ### How much does it cost? Free trial: 20 documents, no credit card. Paid from $20/month on yearly billing (100 docs/month). Enterprise volume on Scale and custom plans. ### Template OCR vs AI IDP for purchase orders -- which do we need? Template-based OCR ("PO number is always top-right") breaks when suppliers change layouts. Modern IDP uses layout + semantics ("text near PO Number") plus validation and review queues -- the approach ChatGPT, Docparser workflow pages, and Klippa procurement guides describe for multi-supplier POs.
