ETR Digital and Calculum combine AI analytics with Working Capital Notes™ to unlock liquidity across supply chains

This collaboration combines Calculum’s Ada platform, which uses AI-driven analytics to assess and optimise payment terms, with ETR Digital’s Working Capital Notes™ (WCNs), helping treasury and procurement teams to unlock liquidity, optimise cash conversion cycles, and support supplier funding needs more efficiently.

Ada is a web-based platform that enables companies to analyse supplier payment terms, cost of debt, sustainability metrics, and assess their working capital performance against their peers. As a result, corporates gain greater visibility into payment terms positioning, liquidity opportunities, and working capital improvement potential across their supply chains.

Meanwhile, Working Capital Notes™ provide a digital framework through which approved B2B invoices can be financed more efficiently, enabling suppliers to access liquidity earlier while supporting more flexible working capital management across supply chains. WCNs can be used by both corporates and financial institutions for growth and value creation – and have gained attention as a solution to sweep aside long-standing inefficiencies in trade and supply chain finance.

“Companies are under increasing pressure to improve liquidity and optimise working capital, but identifying optimisation opportunities is only part of the challenge. Calculum is excited to further integrate with ETR Digital to provide our customers with a holistic solution,” said Oliver Belin, CEO, Calculum. “Combining the power of both analysis and solution-driven technology gives our customers a full-service offering from one platform. This will empower businesses to unlock the full potential of their financial supply chains – and achieve sustainable growth.”

Wayne Mills, CPO, ETR Digital, commented: “Working capital has become a much more strategic priority for both treasury and procurement teams, particularly in sectors managing long payment cycles and complex international supply chains. Earlier access to liquidity can have a meaningful impact across supplier networks, but implementation needs to work within existing commercial relationships and operational processes. As such, we are delighted to deepen our partnership with Calculum – the powerful combination of their AI technology and our WCN service represents a transformational offering for corporate treasury and procurement teams globally.”
