Following the success of Navan’s partnership with the wider Viessmann Generations Group, ISOPLUS has chosen to consolidate its travel and expense operations with Navan – moving away from significant unmanaged travel and expense.

“Navan automates that tedious work and gives us the real-time financial control we need to run a tighter, more efficient business,” said Dirk Seibert, Head of Group Legal & HR, and Chief Compliance Officer, ISOPLUS. “We’re looking forward to introducing the technology at ISOPLUS, and giving more employees an easier experience and more compliant process for booking travel and managing expenses.”

Previously, a lack of proactive policy control meant that ISOPLUS had an estimated 25% of travel booked outside of its system, leading to uncontrolled overspend. Additionally, the finance team was processing approximately 6,000 expense reports per year, with a lack of control and high manual effort. By deploying Navan, ISOPLUS anticipates a 10% cost reduction in travel spend by establishing smarter automated workflows.

“When a business is pushing for serious, long-term growth, they need to be out in the world meeting clients and building new business relationships,” said Zahir Abdelouhab, SVP, Enterprise Sales, Navan. “The last thing it needs is a slow and fragmented travel and expense solution. We’re thrilled to help bring the Navan experience to ISOPLUS employees.”
