Rossum

Rossum is an intelligent document processing platform that helps you automate the way your business handles incoming paperwork. Instead of manually typing data from invoices or purchase orders into your ERP, you can use its AI engine to read and understand documents just like a human would. It captures data with high accuracy, even when layouts change, so your team can focus on exceptions rather than repetitive entry.

You can manage the entire document lifecycle from a single cloud-based interface, from initial capture to final validation and integration. The platform is designed for mid-market and enterprise companies processing high volumes of documents across finance, logistics, and shared services. By reducing manual touchpoints, you can significantly speed up your approval cycles and eliminate costly human errors in your financial records.
