Coupa Acquires AI Document Processing Provider Rossum
Coupa has acquired Rossum, a provider of AI-powered intelligent document processing (IDP), as the spend management platform looks to expand its automation capabilities across the source-to-pay process.
The deal builds on an existing partnership between the two companies, which began in 2024 and focused on automating complex invoicing processes for Accounts Payable (AP) teams. According to the companies, the acquisition will extend Rossum’s IDP technology across the wider Coupa platform, with the aim of supporting autonomous spend management through agentic AI.
Rossum’s technology is powered by what the company describes as a Transactional Large Language Model (T-LLM), trained on transactional documents to process invoices and other supply chain paperwork. Coupa said customers will be able to use the technology to support faster document processing, reduce manual workloads, and improve control over transaction data across direct and indirect spend.
In a statement announcing the acquisition, Coupa CEO, Leagh Turner said: “Rossum changes the game entirely. As a strong partner since 2024, we know there is incredible value in bringing the two companies together across the entire source-to-pay function.”
Turner added: “The combined value of Coupa and Rossum has been proven in AP and invoicing, and we see massive future value in applying Rossum’s T-LLM and AI-first technology across the Coupa platform. We’ve been able to deliver over $300 billion in customer savings over the past 20 years. With Rossum, we believe we can help them save the next $300 billion in five with a system of decision and intelligence that is unrivaled.”
Tomáš Gogár, Rossum CEO and Co-Founder said the acquisition represented “the natural evolution of a years-long partnership built on a shared AI-first culture.”
“By combining our proprietary T-LLM transactional intelligence with Coupa’s massive $10T data set, we are well positioned to create immediate customer value and fundamentally change how the world buys and sells,” he said.
Why Did Coupa Acquire Rossum?
In a blog post about the acquisition, Turner said document processing remains a major challenge for businesses managing transactions between buyers and suppliers.
“Every transaction between a buyer and a supplier starts with a document,” she wrote. “It sounds simple, but around the world, billions of transactions occur every day across businesses, generating mountains of paperwork in over 100 million different formats and layouts.”
Turner also highlighted Rossum’s AI-native architecture and its ability to process invoices, purchase orders, shipping notices, and financial statements without relying on traditional OCR templates.
“They have built a proprietary Transactional Large Language Model (T-LLM) explicitly engineered for high-stakes, financially critical operations. This template-free AI understands documents dynamically, extracting data with more than 90% accuracy and validating it against master data in real time. And it achieves this while remaining uniquely resilient to the hallucinations that plague general-purpose AI models because it’s trained on actual customer documents.”
According to Coupa, integrating Rossum’s technology into its platform will allow its AI agents to “read, understand, and act on any document from any supplier, in any format,” enabling more automated workflows across procurement and finance processes.
