co-source, outsource & advisory solutions
In-house payroll often hides costly risks you can’t see until it’s too late, even though it might feel like you’re in control.
On the surface, handling payroll internally seems like a smart way to save money and stay nimble. You know your systems, team, and schedule, but what looks efficient can quickly become a drain on your time, compliance, and your bottom line. This guide exposes the real cost of in-house payroll, from opportunity loss and compliance pitfalls to hidden software fees and classification errors.
HORNE’s Client Advisory Services (CAS) team works with construction, healthcare, nonprofit, and other businesses to reduce risk, simplify processes, and ensure nothing slips through the cracks. Explore our self-assessment checklist, review common payroll risks, and see why many businesses are rethinking the DIY approach in favor of trusted support.

In the guide, you’ll learn:
The hidden costs of in-house payroll, including time drain, human error, and compliance penalties. You’ll see how internal processes can quietly cost more than you realize.
