How to Transition From ASO to PEO: A Smart Move for Growing Businesses

Written by Comploy | Sep 1, 2025 6:00:00 AM

When your business is small, an ASO (Administrative Services Organization) can feel like enough. It helps with payroll and a few HR tasks, but as your team grows, so do your challenges. That’s when moving to a PEO (Professional Employer Organization) makes all the difference.

If you’ve been using an ASO, here’s what it means to switch to a PEO — and why it’s the smarter long-term choice for small and medium-sized businesses.

Why ASOs Fall Short as You Grow

An ASO is designed for basic help. You’re still the one responsible for compliance, taxes, and benefits. For a small team, that may work. But as soon as you grow, cracks start to show:

  • Compliance gets complicated — keeping up with changing state and federal rules is tough.
  • Benefits cost more — small companies can’t always offer the same perks bigger employers can.
  • Risk stays with you — if something goes wrong, you’re the one on the hook.

What You Gain by Switching to a PEO

With a PEO, you get a true HR partner — not just admin support. That means:

  • Better benefits at better rates — health insurance, retirement, and more.
  • Shared compliance responsibility — the PEO helps carry the legal and tax burden.
  • Simplified payroll and HR — one system that takes care of it all.
  • More time to focus on your business — instead of HR headaches.

How to Make the Switch From ASO to PEO

  1. Review your current contract
    Know your ASO’s cancellation terms and timing.

  2. Choose the right PEO
    Look for one that can handle payroll, compliance, and benefits under one roof.

  3. Communicate with your team
    Let employees know what’s changing and highlight the benefits they’ll gain.

  4. Transition your systems
    Your PEO will take over payroll and compliance filings.

  5. Onboard smoothly
    Work closely with your PEO during setup to minimize disruptions.

Why Now Is the Right Time

As a small or mid-sized business, you can’t afford costly payroll mistakes, compliance penalties, or weak benefits packages. A PEO gives you the resources and protection of a larger company — without losing control of your business.

Ready to Grow?

Moving from an ASO to a PEO is more than just changing service providers — it’s a step toward growth. With a PEO, you can simplify HR, offer employees better benefits, and free up your time to focus on what matters most: running your business.
