[EMEA] cisbox and Millum form pan-European Source-to-Pay software provider
19 Mar 2026

The AI-powered Procure-to-Pay software provider cisbox and Millum, a Nordic procurement and order management SaaS provider, have announced a strategic partnership to create a pan-European Source-to-Pay software provider. 

Their union significantly expands the group’s geographic footprint across the DACH and Nordic regions and results in a broader, fully integrated product suite tailored to the needs of SME and mid-market customers.

Funds advised by Main Capital Partners will still hold a majority stake in the combined group. According to Main, this transaction reflects a strategy of building larger, category-leading software groups within attractive product markets through targeted buy-and-build.

The strategic merger has reportedly resulted in a significantly expanded Procure-to-Pay capability, which sees Millum’s procurement and vertical expertise combine with cisbox’s AI-driven accounts payable automation, e-accounting, and integrated payment capabilities. 

The integrated offering covers procurement, supplier management, invoice capture and validation, payment execution and analytics within one unified platform. Through this combination, the group says it has deepened and expanded its Procure-to-Pay suite and taken a decisive step toward becoming a more complete Office-of-the-CFO software platform.

Dorian Berndt - Investment Director at Main Capital Partners - said, “The combination of cisbox and Millum represents another important step in our strategy to build market-leading software groups in attractive product markets. By bringing together two complementary platforms with strong recurring revenue profiles, we are creating a scalable and strategically well-positioned pan-European Office of the CFO group.”

Christof Majer - CEO of cisbox - said, “We are delighted to join forces with Millum and take another important step toward building a leading Procure-to-Pay platform in Europe. By combining Millum’s best-in-class eProcurement capabilities with cisbox’s AP automation platform, we are creating a powerful end-to-end solution that enables companies to seamlessly manage their entire back-office process from purchase to payment. This partnership also marks an important milestone in our international expansion, as cisbox already supports customers operating in more than 30 markets across Europe and the United States.”

Bjørn Anskau - CEO of Millum - said, “By partnering with cisbox, we are taking Millum’s Nordic procurement expertise to a broader European stage. Our shared vision and cultural alignment make this an ideal partnership for delivering long‑term innovation and customer value.”
