Why OneSource Virtual
➜ In your tenant, not alongside it
Most partners work around Workday. We work inside it. Our patented in-tenant technology means no data movement, no integrations to manage, and real-time visibility into your entire Workday ecosystem — and everything we do on your behalf.
➜ A track record you can count on
We process more payroll, benefits, and payments each week than any other Workday partner. That includes 1,500+ customers who stay with us year after year.
➜ Service built around your business
Our teams don’t hand you a playbook and step back. We bring dedicated service models, deep Workday knowledge, and a proactive approach that adapts to how your organization actually operates. We only succeed when you succeed.

Workday and OneSource Virtual
We know the ins and outs of Workday because we've lived in it since the beginning, as employees, customers, and partners. OSV has been exclusively focused on Workday since 2008, building our payroll, benefits, and finance services around how the platform works. We're a partner woven into the same ecosystem your business already runs on, so your team can spend less time administering Workday and more time building on it.
Real results for real teams
"I would never want to use Workday without OneSource Virtual."
Rachelle Dugan, Director of Payroll, Purple
“They understand multi-jurisdiction states, understanding compliances for state locals, garnishments. It’s having someone that’s almost like an extension of your team.”
Angela Waters, Senior Payroll Manager, Del Monte Foods
“OSV is an integral partner for my operations. It’s important for me to make sure my lights stay on at Unum. Having OSV to help me make payments in an effective and efficient manner is crucial for our operations.”
Walter Leinberger, Director of Procure-to-Pay Operations, Unum
“Our employees don’t even know they’re not talking to someone on the benefits team. They think they are talking to one of us. That’s how knowledgeable [OSV is] on our culture, our benefits, on our processes, the way we talk to our employees.”
