Delivering confidence and empowering our clients

CNS Treasury Software creates a simplified, digitised approach to treasury management through a fully integrated, fully functional, and affordable treasury management platform that anyone can access anywhere, anytime.

Our story

CNS Treasury was the software aspect of Tuatara Management, an investment company turned foreign exchange broking business. Initially, we ran the FX broking business on spreadsheets, word documents, and exercise books — and the best accounting package we could find.

But what we really needed was a purpose-built system. There was nothing on the open market. As they say, necessity is the mother of invention. By 1995 we had built our Deal Management System (DMS).

We then started on another product we had dubbed ‘Currency Navigation System’ (or CNS, as it later became known). The name had been born out of a sailing excursion on a yacht. I (Hils- founder) was struck by the way its state-of-the-art navigation system made it easier to negotiate our passage.

CNS Treasury was up and running. It revolutionised our FX broking business and our clients' business. It reduced our workload, increased our accuracy, and provided reporting so detailed that we could confidently guide our clients on financial and regulatory reporting.

“Throughout the 17-year relationship and our exposures growing 3x, CNS has provided us with strong governance controls and real-time visibility over our Treasury exposures. The automated IFRS9 workflow takes the complexity out of compliance and has resulted in a smooth and shorter audit process. Plus, the integrations with our banking syndicate have saved a couple of days per month of manual process. We want to focus on our core business, and CNS Treasury allows us to do so.”

Mike Wennekes


Silver Fern Farms

“CNS is a great tool. We love the transparency. The more we use it the more control over our FX management we have. CNS gives us the ability to manage risk –this is its single biggest strength for us.”

Marty Verry


Red Stag Group

“With a large number of deals in the system at any one time, we need to have complete confidence in our treasury system. For us, the emphasis is not only on CNS’s ability to effectively deliver, but the ability to further develop existing functionality for our requirements and a strong, ongoing business relationship.”

Paresh Patel

Head of Financial Control

Sky Network Television

"CNS has improved our control and overall management of our foreign exchange exposures"

Jane Mottershead

Former CFO

Vulcan Steed Ltd

“An unexpected bonus is that CNS Treasury has proved to be the sharp end of our financial analysis because it's able to highlight through bar charts and line graphs data entry issues in Dynamics. CNS’s ROI has proven to be short because foreign exchange cover is costly if taken too late, too much or too little.”

Wayne Leach

Former CFO

Westland Milk Products

"We had never managed to get any data out of our old ERP in a format that could even be keyed into a spreadsheet. The integration of CNS and Dynamics AX was a big step forward from that perspective. We could suddenly get data out easily from AX and put it into CNS"

Mark Smitheram

Former CFO
