Invoice OCR software for accounts payable
Capture supplier invoices from scanner, PDF or email, extract header fields and line items with OCR and AI, validate them against your vendor master and export clean data to your ERP. On your own servers, with a perpetual license.
Free for non-commercial use · On-premise, no subscription
Real capture: an invoice processed in ChronoScan Desktop, from empty form to validated fields.
How invoice processing works in ChronoScan
Three stages, configured once per job and then run attended or unattended.
Capture
Invoices arrive from any source and are separated into documents automatically.
- TWAIN scanners and MFPs
- PDF files, including native PDF text extraction
- Hot folders for unattended intake (Advanced, Enterprise)
- Email attachments via IMAP (Enterprise)
- Document separation by barcode, blank page or content
Extract
Header fields and line items are read without building a template for every supplier.
- Four OCR engines: ChronoScan, Tesseract, Nuance, Google Vision
- Intelli-Tag finds dates, totals and invoice numbers by their labels
- MasterKey detects the supplier and applies its settings (Advanced, Enterprise)
- AI extraction with GPT, Gemini or on-premise models via Ollama
- Line items into data grids: quantity, description, price, VAT
Validate & export
Data is checked before it reaches your accounting system.
- Real-time lookup against your vendor master and PO tables (ODBC)
- Flag duplicate invoice numbers by validating against your database
- Field rules, formats and totals checks with operator review of exceptions
- Export to your ERP database, files, REST API or document management system
- VBScript and PowerShell actions for custom logic
Any Input Source
Paper, native PDFs, hot folders and, in Enterprise, email attachments: all captured by the same job.
Header & Line Items
Invoice header plus every detail line, in up to 6 configurable data grids per job.
Supplier Detection
MasterKey recognises the supplier and Intelli-Tag locates its typical fields, so most invoices need no template.
Database Validation
Validate and auto-fill fields from SQL Server, MySQL, Oracle, Access or any ODBC source during capture.
AI Extraction
Cloud models for maximum accuracy or on-premise models for full data privacy. Image-capable models read the scan directly.
Unattended Automation
Hot folders process invoices as they arrive, overnight or around the clock, with exceptions queued for review.
ERP Integration
Direct database export, XML and CSV, REST JSON, SharePoint, M-Files, CMIS repositories and scripted connectors.
Multi-User Workflow
Enterprise adds client/server operation, user roles, a thin web client and real-time notifications for AP teams.
Where the invoice data goes
Each job can combine several output modules, so the same invoice can feed your ERP and your document archive in one pass.
