Paychex vs. Managed Payroll: What's the Actual Difference?

Paychex Flex is one of the most established payroll platforms for mid-size businesses. But like all payroll software, it still requires someone at your company to run it. Here's what changes when that doesn't have to be you.

Paychex has been in the payroll business since 1971. It's one of the most recognizable names in the space, and Paychex Flex -- its cloud-based platform -- serves over 700,000 businesses. For companies that want a stable, well-supported payroll platform, it's a legitimate option.

The question we get from HR managers and CFOs who are evaluating Paychex is usually the same: "We're spending too much time on payroll. Will Paychex fix that?" The honest answer: it'll make it easier to run payroll yourself. It won't take payroll off your plate.

The Key Insight: Staying on Paychex Doesn't Have to Mean Running Payroll Yourself

This is something many companies don't realize: BEG managed payroll can operate within your existing Paychex account. We don't require you to switch platforms. If you're on Paychex and want the operational burden off your team, we can take over the processing while you stay on the platform you're already invested in.

Alternatively, if your Paychex contract is up for renewal and you want to evaluate switching to isolved alongside the managed service, we can handle that migration too.
