“Payroll is one of those things you just have to get right, and you’re going to hear when it’s wrong. OSV has been a really good partner. It’s been great because OSV really specializes in this service. So for us, we don’t have to worry.”
Matt Sidholm, VP of Total Rewards and People Operations, Integrity Marketing
When traditional solutions won’t cut it
When Matt Sidholm joined Integrity Marketing four years ago as their VP of total rewards and people operations, he soon realized the company had outgrown its payroll system. They’d scaled from 200 employees to thousands, and what once worked no longer made sense.
“At a certain point, you realize you need a new house,” Matt says. “There’s just too many things broken here.”
Rather than choosing a monolithic payroll processing provider, Integrity asked who the actual payroll experts were. Operating across 48 states requires depth in payroll tax services. There's federal compliance, state regulations, local taxes, and constant rate changes. Many vendors treat this as one service among dozens. OneSource Virtual (OSV) specializes in exactly this.
“OSV really specializes in this service. So for us, we don’t have to worry,” Matt notes. When state agencies question historical filings or Integrity acquires a company, OSV’s payroll experts have the documentation ready. This proved invaluable to Integrity’s team.
Building on expertise: from compliance to total rewards
Four years in, trust was established. When Matt noticed that Integrity’s workforce began requesting flexible pay and payroll advances, expanding the partnership with OSV felt natural. Rather than adding another vendor, myFlexPay fit in with their existing Workday infrastructure.
Total rewards programs work best when they’re unified with other functions of the business, not as a disconnected vendor ecosystem. Employees received a meaningful benefit. Payroll teams got simplicity. Integrity maintained employee goodwill.
“OSV had a nice little roadmap to gain adoption, and adoption happened across the board. We’ve seen people at all levels of the company use it,” Matt says.
The payroll experts Integrity chose became strategic experts in their approach to employee financial well-being, not mere processors managing compliance.
