S4BT responds to client demand for financial operating system for modern corporate travel with launch of Trevium

Paris, 27 January 2026

Following demand from clients for a more modern financial operating system for corporate travel, S4BT – Solutions for Business Travel today announces the launch of Trevium. 

This next-generation financial solution is designed to modernise how travel-related payments and expenditure are managed across Europe for a market still reliant on fragmented legacy processes.

Trevium introduces a unified, end-to-end approach to corporate travel financial operations for TMCs, corporate clients and hotels, including centralised and automated payments, invoice capture, validation and reconciliation, VAT reclaim and reporting within a single system.

All clients already working with S4BT through any of its entities can access Trevium automatically and by default. No additional onboarding, opt-in or contractual changes are required.

As a leading European technology group dedicated to business travel, S4BT includes seven specialist brands: CDS, Goelett, CRC, TMS, SIAP, Methodica and now Trevium.

Together the group employs more than 450 people and manages over €800 million in annual corporate travel hotel bookings for thousands of clients – whilst supporting almost €4 billion in corporate travel flows, across bookings, hotel volumes and invoicing processed through its technology ecosystem.

Ziad Minkara, CEO and Founder of S4BT, commented:
“We’ve heard time and again from clients of all sizes and geographies about the challenges they face managing payments and finances, and have decided to solve this problem for them once and for all. As such, Trevium was founded on a simple conviction: when you manage such volumes of travel flows, mastering the flows becomes the quiet force behind transformation — because the one who controls the flows ultimately shapes the future of business travel.”  

Trevium’s modular, API-first architecture allows seamless integration with existing travel and finance platforms to replace disconnected, legacy tools with a single financial backbone. Advanced automation and AI-driven data processing capture and classify invoices from hotels, mobility providers, agencies and suppliers across multiple markets. Meanwhile data is automatically validated against bookings, traveller information, internal policies and rates, significantly reducing manual effort and improving accuracy and operational efficiency.

Beyond productivity gains, Trevium strengthens financial control and compliance. It supports VAT reclaim across European jurisdictions, accelerates reconciliation cycles and provides organisations with a consolidated, auditable view of travel expenditure. Sustainability data is embedded directly into the financial workflow, enabling companies to measure and report CO₂ emissions with the level of accuracy required for ESG and regulatory reporting.

“Our industry has made significant progress in distribution and content, but the financial backbone of business travel has remained fragmented for too long,” said Christopher Hecht, Group Chief Payment Officer at S4BT and CEO of Goelett. “With Trevium, we’re giving the market a modern financial engine designed specifically for the realities of European business travel. It’s smarter, faster and built to integrate with the platforms shaping the future of the sector.”

Ziad Minkara added:

“Watch this space as S4BT continues to innovate and enter new markets in Europe.”
