OneSource Virtual Appoints John Bax CEO, Accelerates Growth Strategy

DALLAS, TX – April 1, 2025 – OneSource Virtual (OSV), a leading provider of BPaaS services within the Workday ecosystem, announced that longtime Chief Financial Officer John Bax will assume the role of Chief Executive Officer on April 1, 2025. He succeeds Trey Campbell, who retires after nearly a decade of leadership at OSV. Trey will continue to serve as an advisor through 2025 and remain a member of OSV’s Board of Directors. 

Since joining OSV in 2016, Trey has played a critical role in shaping the company’s strategic direction, fostering innovation, and reinforcing OSV’s reputation as a trusted partner for Workday customers. Under his leadership, OSV expanded its capabilities and deepened its commitment to delivering resilient payroll, benefits, and finance solutions that uniquely blend technology and service. 

Stepping into the CEO role, John brings a deep understanding of OSV’s business, customers, and market, having served as CFO since 2016. Over the years, John has worked closely with Trey to guide OSV through major milestones, including the 2022 decision to focus exclusively on BPaaS solutions for Workday customers, following the divestiture of its professional services and application maintenance practices. His financial leadership has been instrumental in ensuring OSV’s long-term stability, driving operational efficiency, and positioning the company for continued growth. 

"This transition couldn’t be smoother — short of Trey and I physically performing a baton handoff,” said John. “After years of working together to shape OSV’s direction, we’ve built the kind of momentum that will carry us forward seamlessly. I’m excited to build on that foundation and accelerate OSV’s success." 

With more than 20 years of experience scaling technology-enabled businesses, executing complex M&A deals, and raising billions in capital, John understands how to balance financial discipline with smart, strategic growth. He has led teams of all sizes and has a track record of helping companies adapt and thrive in evolving markets. Over the past nine years at OSV, John has been instrumental in the release of new payroll, finance, and financial well-being products, sevenfold BPaaS growth, and the facilitation of nearly one trillion dollars in compliant payments. 

“OSV plays a crucial role in keeping businesses compliant across a myriad of mission-critical activities,” said John. “Timely, compliant payments are the backbone of business operations. They keep employees and vendors paid, businesses running, and trust intact. I look forward to leading OSV into this next chapter, continuing to innovate, and making sure our customers have the support and expertise they need to navigate an increasingly complex landscape.” 

The company remains focused on delivering high-impact, technology-enabled services that help Workday customers run more efficiently, stay compliant, and support their people with confidence. Backed by proven success, a clear vision, and a deep bench of experienced leaders, OSV is well-positioned to accelerate its growth and continue setting the standard for BPaaS excellence in the Workday ecosystem.
