If 2024 was the year OCR proved it works, 2025 is the year finance leaders make it standard. In this guide, I break down the top OCR solutions for invoice processing and accounts payable, and share what to look for when choosing the right tool.

What is OCR for Invoice Processing & Accounts Payable?

OCR for invoice processing and AP, also known as invoice OCR, uses technology to automatically read printed or scanned invoice text and convert it into structured, machine-readable data for accounts payable workflows.

Modern OCR goes beyond simple text capture. The best tools use AI to locate specific fields like invoice number, dates, totals, line items, and vendor details, then validate that data before integrating it into your ERP or finance system. This reduces repetitive data entry, improves accuracy, and speeds approvals.

Key Features to Consider in 2025

Choosing OCR software for invoice processing and accounts payable is not just about selecting the most popular product. The right choice depends on your document types, existing systems, compliance needs, and processing volume. 

Below are the factors that I’ve found are most commonly evaluated by finance and AP teams across industries in 2025.

• Accuracy: High field-level accuracy reduces the need for manual correction. Look for solutions consistently reporting 95%+ accuracy and the ability to capture both header and line items reliably.

• Customization: Invoices vary by vendor, and formats often change. OCR tools that allow dynamic field mapping, custom extraction rules, or model training offer greater flexibility.

• Integrations: The OCR software should connect smoothly with your ERP, AP automation software, or accounting platform. Direct integrations and API support help eliminate duplicate data handling and speed up workflows.

• Speed & Scalability: Processing speed is critical during high-volume periods. Check whether the software can maintain performance under load and if it scales easily without impacting accuracy.

• Compliance & Security: Ensure the provider meets industry standards such as ISO 27001, SOC 2, and GDPR. Sensitive financial data must be encrypted in transit and at rest, and access controls should be role-based.

• Document Type Support: Verify the OCR can handle all your invoice sources – PDFs, scanned images, emails with attachments, and even photographed documents from mobile devices.

• Ease of Use: The platform should be straightforward for AP staff to operate without requiring constant IT support. A good interface can significantly cut training time and errors.
