ETR Digital and Calculum Announce Partnership Collaboration to Provide Financial Supply Chain Optimisation to Corporate Clients

Published: March 11, 2025

ETR Digital, a leading London-based technology firm specialising in unlocking working capital, and Calculum, a US-based pioneer in AI-powered financial supply chain analytics, today announced a strategic partnership to assist corporates in releasing trapped working capital and improving cash conversion cycles, through payment terms analytics and the adoption of Digital Negotiable Instruments (DNIs).

Combining the power of Calculum’s AI supply chain analytics platform with ETR Digital’s DNI technology, corporates can now evaluate and act on unlocking working capital in a simple, easy to consume way.

Calculum’s ADA Platform allows organisations to compare themselves with their competitors. With the web-based platform leveraging artificial intelligence, companies can analyse all their suppliers’ payment terms, cost of debt, sustainability, metrics, and seize all the necessary arguments to negotiate more favorable terms.

“Calculum is excited to join forces with ETR Digital,” said Karel Krejci, Head of Working Capital Advisory Excellence at Calculum. “Together, we will empower businesses to unlock the full potential of their financial supply chains and achieve sustainable growth.”

ETR Digital’s easy to adopt technology generates highly secure, referenceable, transferable and enforceable DNIs, which enable corporates to improve their Cash Conversion Cycles, by releasing trapped working capital, whilst embedding supply chain resilience.

Digital bills of exchange and promissory notes 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.

“We are delighted to partner with Calculum. The powerful combination of their AI technology and our DNI application represents, for the first time ever, a transformational offering for Corporate Treasurers globally.” said Dominic Broom, CEO of ETR Digital.
