Understanding professional employer organizations.

What is a professional employer organization?

A professional employer organization is a company that provides outsourced HR services to small and midsize businesses. The PEO becomes the employer for administrative purposes, but the business retains full control over day-to-day operations and its legal entity.

With this structure, companies can access professional employer organization services such as payroll processing, benefits administration, risk management, and HR compliance without building an in-house team for every function.

PEO typically includes three types:

• Full-service PEOs offering end-to-end HR support.

• Administrative services organizations (ASOs) that focus on compliance and benefits.

• Specialized PEOs that cater to specific HR niches, such as temporary staffing, or industries, like manufacturing.

The origins of professional employer organizations.

PEOs became more widespread in the 1970s and 80s as labor regulations became more complex, causing small and midsize companies difficulty in keeping up. Many lacked the internal resources to manage compliance, payroll, and benefits. Early PEOs started to fill that gap—starting with payroll and benefits administration. Over time, their services expanded to include more intricate HR functions, including onboarding, international compliance management, and risk management.

Professional employer organization (PEO) vs. Employer of Record (EOR).

PEOs and EORs serve different purposes for companies. A PEO takes over administrative HR tasks for a company, but the company maintains its legal status as the employer. An EOR, on the other hand, becomes a legal employer on behalf of a company, enabling businesses to hire in new states or countries without setting up a local entity.

Understanding these distinctions is key to choosing the right model for your total workforce management strategy. Here are the core differences:

The advantages of a professional employer organization.

Working with a professional employer organization gives growing companies access to big-company HR infrastructure without the typical overhead. PEOs have numerous benefits for organizations needing support, including managing complex compliance requirements and supporting better employee benefits.

Better compliance across jurisdictions.

When companies expand into new states or regions, keeping up with local labor laws, tax requirements, and employee classification rules becomes more challenging. PEOs take on the burden of compliance by handling filings, monitoring regulatory changes, and reducing the risk of costly mistakes or audits.

Cost savings through better benefits management.

PEOs tap collective bargaining power to offer small and mid-size businesses access to high-quality, cost-effective employee benefits packages. This includes health insurance, retirement plans, and wellness programs, which can increase employee satisfaction and retention.

By negotiating with several insurance carriers, PEOs can likely find more affordable options than your company could find on its own. As a result, businesses using a PEO have an estimated ROI of 27%, according to NAPEO.

Reduced administrative burden on internal teams.

By outsourcing HR tasks including payroll processing, benefits administration, and tax filings to a PEO, companies can alleviate the administrative workload on internal teams and focus more on strategic initiatives and core operations. When paired with the Workday AI platform, businesses can streamline information across platforms while equipping teams to manage performance, request time off, and lead their own growth in a single place. This kind of integration enables HR teams to stay agile, even as the organization grows.

Improved risk management and liability sharing.

One in four small businesses says it is one crisis away from shutting down, according to the MetLife & U.S. Chamber of Commerce Small Business Index for Q1 2024. PEOs provide expertise in managing employment-related risks, including workers' compensation and workplace safety, to prevent business-damaging disasters. They assist in developing and implementing safety programs and can help manage claims, which reduces potential liabilities for the business.

Scalable HR infrastructure for growth.

As businesses grow, their HR duties often become more complex. The scalable solutions of PEOs can adapt to a company's evolving requirements, providing the necessary infrastructure to support expansion.

For example, a retail brand opening stores in new states can rely on a PEO to manage multi-state compliance, benefits enrollment, and payroll without hiring a full HR team in each location. Similarly, a tech startup scaling from 25 to 200 employees might use a PEO to introduce structured onboarding and competitive benefits to its team.

Navigating the challenges of a professional employer organization.

PEOs often create complications for teams during implementation or the early phases. There can be confusion about roles, transitions, and expectations versus delivery. These potential challenges shouldn't be dealbreakers for your team, but you should know what to expect and how to address common problems up front.

Less control over certain HR processes.

Working with a PEO means sharing responsibilities, especially around payroll, benefits, and compliance filings. While this can save time, it may also feel restrictive if internal teams usually own these functions directly.

Solution: Keep a designated internal point of contact for each HR area and schedule regular check-ins with your PEO to keep the team informed.

Co-employment confusion.

The co-employment model can be difficult to explain to employees or new hires. It may raise questions about who employs them, especially when they receive paperwork or benefits information from an outside company.

Solution: Educate your team early on about what co-employment means and why you're using it. Focus on the benefits that apply to them, such as managed employee benefit packages and advanced payroll support.

One-size-fits-all service models.

Some PEOs offer standardized packages that may not match your industry-specific needs or internal workflows. Your company may overpay for services it doesn’t need, or a PEO may not have all the features or services you expect.

Solution: Choose a PEO with flexible service tiers and ask detailed questions during onboarding. Many providers can customize support if you’re clear about your expectations and growth plans.

How to implement a successful professional employer organization.

Bringing a PEO into your organization introduces new workflows to handle HR tasks. To succeed, your team needs to be on board with adopting new workflows and making the transition as smooth as possible. A successful transition requires a strong foundation so your internal teams and PEO partners can work toward the same goals together.

Here's what to do:

1. Build internal alignment early.

Bring in your finance, HR, and legal leads at the start of PEO discussions so that everyone understands the scope of the partnership and how responsibilities will change. Be ready to provide answers to employees about what’s changing and what’s not. Reassure them that only back-end processes are shifting, not their jobs, managers, and workplace culture. Misalignment here slows down the rollout and can create trust issues later, especially with payroll and benefits on the line.

2. Choose a PEO that fits your structure.

Narrow your search to PEOs that understand your industry and can scale with your business. When comparing options, ask detailed questions about how they manage state-specific compliance and how customizable their services are. Also, be sure that the PEO integrates with existing tech and can sync data smoothly.

3. Map your data and processes.

Your PEO may require specific preparation for data to move to its systems. Talk to your PEO about data formats and how to prepare it for the move. Usually, this requires cleaning up and organizing records. You may also want to document how current processes work to share with your PEO.

4. Assign internal liaisons.

An in-house team should own the relationship between the company and the PEO. This team can include experts from finance and HR who can communicate clearly with PEO contacts to keep them updated on internal processes and ensure projects stay on track.

5. Use a phased rollout.

If possible, deploy the PEO in phases. Start with payroll and compliance, then layer in benefits or onboarding support. This gives your team time to adjust, and it empowers the PEO to learn the ins and outs of the business.

6. Review performance regularly.

Once in place, the PEO should feel like a trusted business partner. That means you should take the same steps as you would with any partner or vendor to ensure performance continues to meet needs and expectations. Set quarterly goals and reviews for your PEO, checking how well it performs with tasks like payroll accuracy or benefits enrollment.
