What Eisner Advisory Group’s Vendor Evaluation Revealed

When Eisner Advisory Group’s ADP integration started causing problems in 2020, they didn’t jump to a new provider overnight. Instead, they spent four months evaluating every option.

That rigorous evaluation process made one thing crystal clear: most providers couldn’t make promises about the level of support they could provide.

But OneSource Virtual (OSV) was different.

Not only could OSV provide immediate support, but Eisner was also confident they would be getting top-tier talent, regardless of what part of the system they were working on.

Because of Greenix’s people-first philosophy, they decided to offer earned wage access (EWA) to their employees. When employees have a way of handling immediate financial stress, they’re better equipped to focus on customers and solving tomorrow’s challenges instead of worrying about today’s problems.

What set OSV apart

As their partnership began, Eisner noticed something else about OSV: its people were warm and straightforward, not mechanical. When OSV couldn’t help with something immediately, they admitted it and worked to find a solution.

For a fast-growing firm like Eisner, these qualities weren’t just nice to have — they were essential. As their director of HRIT put it, OSV gives them “the best chance at being successful at what we do.” That kind of support matters when you’re scaling quickly and need a partner who can keep pace.

Years later, that decision has proven right. Eisner and OSV’s relationship remains strong, with quick responses and ongoing support that, for Eisner, feels like working with an extension of their own team.

• Why resource transparency mattered more than sales promises for Eisner
• How OSV's honesty built a level of trust that competitors couldn't match
