For many small and mid-sized businesses, the real question is whether sticking with open market health insurance still makes sense or if there’s a better path forward.
In this guide, we’ll break down:
Let’s start by defining what open market health insurance really looks like in practice.
Open market health insurance refers to coverage that a business purchases directly from insurers or through a broker, without going through a third-party partner like a PEO.
For most small and mid-sized businesses, this means navigating the ACA small group market. Though thresholds can vary by state, this marketplace is typically for companies with fewer than 50 full-time employees.
Pricing for open market health insurance is usually influenced by factors like employee demographics, location, and overall risk profile. While this approach offers control, it also places the burden of decision-making and management squarely on the employer.
When you choose open market coverage, your team takes on several key responsibilities:
This structure gives you flexibility, but it also means your internal team must develop expertise across benefits, compliance, and administration. For many businesses, that tradeoff becomes more noticeable as they grow.
A PEO approaches health insurance by combining benefits administration, access to structured health plan offerings, HR support, and compliance guidance into a single, integrated system. Instead of managing everything internally, businesses work alongside a PEO to access structured benefit offerings and ongoing operational support.
At the core of this model is a co-employment relationship, where certain administrative responsibilities are shared. The business maintains control over day-to-day operations and employee management, while the PEO helps handle benefits, payroll, and HR infrastructure behind the scenes.
With a PEO, many of the most time-consuming and complex tasks are supported externally:
Instead of building expertise across multiple areas, you gain access to systems and support designed to streamline the entire benefits experience.
The biggest difference between PEO and open market health insurance comes down to cost stability, plan access, administrative workload, and risk exposure. These factors directly affect both your bottom line and your day-to-day operations.
For small and mid-sized businesses, the contrast becomes clearer when you look at how each model performs under real-world conditions like renewals, hiring, and compliance demands.

Factor |
Open Market Health Insurance |
PEO Model |
|
Cost Stability |
Premiums can fluctuate significantly year-over-year based on claims and market shifts |
More structured pricing with generally reduced volatility in renewals |
|
Plan Options |
Often limited for smaller groups |
Access to large-group benefit options with potential for more competitive offerings |
|
Administrative Work |
Managed internally by your team |
Supported through centralized systems and services |
|
Compliance Support |
Employer is responsible for tracking requirements |
Guidance and support to help maintain compliance |
|
Employee Experience |
Can vary based on internal resources |
More consistent experience with integrated tools and support |
Each of these differences compounds over time. For example, a single high-claim year on the open market can lead to sharp premium increases, while administrative demands grow as your workforce expands.
What this means in practice:
Understanding these tradeoffs is key. The right choice depends on how much time, risk, and complexity your business is prepared to manage as it grows.
Open market health insurance can make sense for businesses that prioritize control and have the internal capacity to manage benefits effectively. In the right circumstances, it remains a practical and straightforward option.
For more stable organizations, the administrative demands and cost variability may be manageable.
These scenarios tend to favor simplicity over scalability. As your business evolves, however, the same factors that make the open market workable early on can become constraints that require a different approach.
A PEO becomes worth considering when the cost, complexity, or risk of managing health insurance internally starts to outpace your team’s capacity. For many growing businesses, this shift happens gradually, then all at once.
As headcount increases, so do administrative demands, compliance requirements, and pressure to offer competitive benefits.
These signals point to a need for more structure and support. At that stage, the conversation often shifts from, “Can we manage this?” to, “Is this the best use of our time and resources?”
Choosing between a PEO and open market health insurance is about deciding how much complexity, risk, and administrative responsibility your business is prepared to carry. As your company grows, those factors tend to compound, making structure and support more valuable over time.
If your current approach to open market health insurance is starting to feel limiting, it may be time to explore alternatives. A partner like BBSI can help you evaluate your options, streamline your benefits strategy, and reduce the operational strain that often comes with managing coverage on your own.
