Coupa Inspire 2026: How Rossum Acquisition Helps AP Teams

Coupa has acquired Rossum in a deal that looks set to reshape how finance teams handle document processing across procurement operations. The spend management specialist announced the acquisition at Coupa Inspire 2026.

Rossum specialises in intelligent document processing and uses AI to automate invoice handling for accounts payable teams. The technology will now extend across Coupa's full product range.

Cost control through automation

Finance leaders using Coupa already access Rossum's capabilities embedded within the platform for accounts payable functions. The acquisition expands this to cover both direct and indirect spend categories.

Rossum operates a transactional large language model trained specifically for financial documents. This could mean faster invoice processing and lower operational costs for finance departments managing complex supplier relationships.

According to Coupa, the technology offers greater data control alongside the processing speed improvements. Finance teams working with high invoice volumes across multiple spend categories could see material efficiency gains.

"Rossum changes the game entirely," says Leagh Turner, CEO at Coupa. "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.

"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 US$300bn in customer savings over the past 20 years. With Rossum, we believe we can help them save the next US$300bn in five with a system of decision and intelligence that is unrivalled."

Tech built for transactions

Rossum's architecture differs from traditional optical character recognition systems. The company has trained its proprietary model on tens of millions of financial documents.

The system learns from each customer's specific document types over time, which stands to accelerate implementation timelines for finance teams adopting the technology.

Coupa operates an agentic AI fleet called Navi – and Rossum's document processing will integrate with this existing infrastructure.

"Joining Coupa is the natural evolution of a years-long partnership built on a shared AI-first culture," comments Tomáš Gogár, Co-Founder and CEO at Rossum.

"By combining our proprietary T-LLM transactional intelligence with Coupa’s massive US$10tn data set, we are well positioned to create immediate customer value and fundamentally change how the world buys and sells.

"We’re excited to join Coupa, especially at this critical acceleration of how businesses use and adopt AI."

Kirkland & Ellis LLP served as counsel to Coupa with respect to the transaction. Guggenheim Securities, LLC served as exclusive financial advisor, while Orrick, Herrington & Sutcliffe LLP served as legal advisor to Rossum.

Coupa will host a webinar on 9 June, examining how the combined Coupa and Rossum offering applies to source-to-pay processes.
