What is Rossum?
Rossum is an AI-based cloud document gateway for automated business communication. Rossum solves four key steps in document-based processes at once: receiving documents across multiple channels, automated understanding, two-way communication to resolve exceptions, and acting on the data using in-depth integrations. In typical real-world scenarios, Rossum’s proprietary AI engine outranks narrow data extraction solutions in accuracy. Meanwhile Rossum’s platform automates the document-based communication process end-to-end. Rossum’s goal for every use case is at minimum a 90% document processing speed increase.

Review Summary
Generated using AI from real user reviews
Rossum earns strong approval from users, with the vast majority rating it highly and emphasizing its ease of use and customization flexibility. The platform excels at extracting invoice data from PDFs and images, and users consistently praise the responsive support team and willingness to engage with customer feedback. Integration with enterprise systems like SAP is straightforward, and the API documentation is widely cited as excellent. Deployment is quick, with no major upfront investment required beyond subscription fees.
The main criticisms are modest and narrow. Large PDF documents can cause performance issues and UI crashes. OCR accuracy, while generally strong (users report 90%+ in many cases), still isn't perfect and depends on proper algorithm training; some users note it struggles with receipts and print-outs. A few mention that data sometimes fails to transmit to downstream systems without warning, and one reviewer flagged US-based support responsiveness as slower than ideal. Another noted difficulty "unlearning" incorrect training patterns. Time zone differences can occasionally delay support responses.
Users across industries—accounting, AP automation, back-office workflows—report significant time savings and reduced manual data entry. The combination of customizable UI, flexible schema definition, and proactive product development distinguishes Rossum from competitors in the OCR space.

Rossum is very progressive and people there are very opened to new ideas and suggestions for improvements of their solution. The product was made so intuitive that any user learns easily how to use it really quickly. Customization of the schema is mostly our topic. We have achieved considerable FTE and cost savings for our clients.
