7 Key Strategies for Evaluating G&A Partners PEO at the 500-Employee Mark

At 500 employees, you’re in an awkward middle zone that most PEO marketing doesn’t address honestly. You’re too large for the “we’ll handle everything, don’t worry about it” pitch that works at 40 employees — but you’re not large enough to have a fully built-out internal HR infrastructure that makes a PEO irrelevant. G&A Partners is a legitimate option at this size. They’re a Texas-based, IRS-certified PEO with real mid-market experience and a track record in the Southwest. But “they can serve companies your size” is not the same as “they’re the right fit for your company at this size.”

That distinction matters more at 500 employees than at any other headcount tier. The financial exposure in a multi-year PEO contract at this scale is significant. Benefits disruption affects hundreds of people. Co-employment liability is real and worth examining closely. And the switching costs — both administrative and operational — are high enough that a bad decision is genuinely painful to unwind.

G&A Partners was also acquired by GreenPoint Capital Partners, which is worth noting as a due diligence point. Ownership transitions can affect service continuity, staffing, and strategic priorities. That doesn’t disqualify them — but it’s a question worth asking directly before you sign or renew.

This guide is a practical evaluation framework. Each strategy below is designed to help you pressure-test a specific dimension of the G&A Partners model at the 500-employee mark. Use it whether you’re evaluating them for the first time or auditing an existing contract ahead of renewal.

1. Understand What Changes About PEO Pricing at 500 Employees

The Challenge It Solves

PEO pricing that felt reasonable at 80 employees can look very different at 500. The math shifts. The absolute dollar amounts get larger. And the difference between pricing models — PEPM versus percentage of payroll — stops being academic and starts being a real budget line item.

The Strategy Explained

G&A Partners typically prices on a PEPM (per-employee-per-month) basis. At 500 employees, that structure has a clear advantage over percentage-of-payroll models if your average wages are high, because your cost doesn’t scale with compensation increases. That’s genuinely useful to understand.

But PEPM pricing still varies significantly by provider, and the base rate isn’t the full story. Administrative fees, benefits markups, workers’ comp loading, and technology fees can all be bundled into or layered on top of the headline PEPM number. At 500 employees, even a modest difference in per-employee cost compounds quickly across your headcount and contract term.

Before accepting G&A Partners’ pricing at face value, you need a line-item breakdown of what’s included in their quote and what’s billed separately. You also need a benchmark against what other mid-market PEOs charge for a comparable service package at your headcount. For context on how PEO pricing structures work and what to expect at different headcount tiers, our PEO pricing guide breaks this down in detail.

Implementation Steps

1. Request a full fee disclosure from G&A Partners — not just the PEPM headline rate, but every line item including benefits admin fees, payroll processing, compliance support, and technology access.

2. Identify whether any fees scale with headcount growth. If you hire 50 more people next year, understand exactly what that costs under their model.

3. Get at least two competing quotes from mid-market PEOs at your exact headcount and payroll profile. You can’t assess value in isolation.

Pro Tips

Don’t let a PEO rep walk you through a total cost calculation without giving you the underlying assumptions in writing. The “all-in” number is only meaningful if you can verify what’s inside it. Ask for a mock invoice format before you sign anything.

2. Audit the Co-Employment Structure Before You Sign

The Challenge It Solves

Co-employment is the foundation of how PEOs work — and most business owners understand it at a surface level. At 500 employees, you need to understand it at a contract level. The liability exposure is real, and the indemnification terms in your agreement determine who absorbs it when something goes wrong.

The Strategy Explained

In a co-employment arrangement, G&A Partners becomes the employer of record for tax and benefits purposes while you retain operational control. That structure is what enables them to provide benefits under their master plan and handle payroll tax filings. It’s also what creates shared legal exposure.

At 500 employees, EPLI (Employment Practices Liability Insurance) matters. Wrongful termination claims, discrimination complaints, and wage and hour disputes become statistically more likely just by virtue of headcount. The question isn’t whether G&A Partners carries EPLI — it’s what the coverage limits are, who’s named, what’s excluded, and what your indemnification obligations look like if a claim arises from your operational decisions versus their administrative errors.

Multi-state operations add another layer. If you have employees in multiple states, understand how G&A Partners handles compliance across different jurisdictions and where liability sits for state-specific employment law violations. For a foundational explanation of how co-employment works, see our guide on what a PEO is — this section assumes you already have that baseline.

Implementation Steps

1. Have your legal counsel review the indemnification clause in the G&A Partners client service agreement before signing. Pay specific attention to which party bears liability for employment claims and under what circumstances.

2. Request the EPLI policy details — coverage limits, named insureds, exclusions, and claims process. Don’t accept a summary; ask for the actual policy or a certificate of coverage with specifics.

3. If you operate in multiple states, ask G&A Partners to walk you through how they handle compliance in each state where you have employees, and confirm they have actual infrastructure there — not just a registered address.

Pro Tips

Pay attention to the contract’s termination clause as carefully as the indemnification clause. If you need to exit the agreement, understanding what liability transfers back to you — and on what timeline — is critical at this headcount.

3. Evaluate Benefits Buying Power Realistically

The Challenge It Solves

The benefits cost argument is often the primary reason companies join a PEO. At 500 employees, that argument deserves real scrutiny — because the math may no longer favor the PEO model the way it did when you were smaller.

The Strategy Explained

PEOs offer access to group health insurance through their master plan, which pools employees across their entire client base. That pooling creates buying power that a 40-person company can’t replicate on its own. At 500 employees, the calculus changes. Many companies at this headcount qualify for their own competitive group rates directly from carriers — sometimes at comparable or better pricing than what they’d access through a PEO.

The relevant question isn’t whether G&A Partners has good benefits. It’s whether their benefits pricing is actually better than what you could negotiate independently at your size. That comparison requires getting a direct-market quote from a benefits broker alongside the G&A Partners proposal — not just taking the PEO’s word that their rates are competitive.

Also worth examining: benefits administration markups. PEOs sometimes layer administrative fees into the benefits component of their pricing. At 500 employees, even a small per-employee markup on health premiums adds up to a meaningful annual cost. Ask G&A Partners to show you the actual carrier rates versus what you’re being charged. If you’re also evaluating other providers at this scale, see how Insperity approaches the 500-employee threshold for a useful point of comparison.

Implementation Steps

1. Engage a benefits broker to run a direct-market quote for your employee population at your current headcount. Use this as your baseline comparison.

2. Ask G&A Partners to provide the underlying carrier rates for their health plans, not just the employee contribution amounts. This lets you identify any markup.

3. Factor in administrative cost savings from benefits management when comparing. The comparison isn’t purely premium rates — it includes the time and staffing cost of administering benefits internally.

Pro Tips

If G&A Partners can’t or won’t show you the underlying carrier rates, that’s a signal worth paying attention to. Transparent PEOs at this headcount tier should be able to show you exactly what the carrier charges versus what you’re paying.

4. Pressure-Test Their HR Service Model for Mid-Market Complexity

The Challenge It Solves

G&A Partners built much of their business serving smaller companies. At 500 employees, your HR needs are materially different — more complex compliance requirements, more employee relations issues, more manager support needs. The question is whether their service model actually scales to meet that complexity, or whether you’re a large client being served through a small-business framework.

The Strategy Explained

There’s a meaningful difference between a PEO that assigns you a dedicated HR consultant who knows your business and one that routes your HR questions through a shared service queue. Both can technically claim to offer “HR support.” Only one of them is actually useful when you’re dealing with a complex termination, a multi-state wage and hour question, or a manager who needs real-time guidance.

At 500 employees, you’ll also have HR needs that go beyond transactional support: performance management frameworks, employee handbook updates, HR policy development, compliance training. Ask G&A Partners specifically how they support these functions — and whether that support is included in your contract or billed as add-on services. For a sense of how another mid-market provider structures HR service delivery at this scale, the Paychex PEO evaluation for 500 employees covers similar territory worth reviewing.

Implementation Steps

1. Ask G&A Partners directly: will you have a named, dedicated HR consultant, or will your account be handled by a team or service queue? Get the answer in writing in the service agreement.

2. Request specific SLAs for HR response times — not just “we’ll get back to you promptly” language, but defined timeframes for different categories of requests.

3. Ask for examples of how they’ve handled HR complexity for clients in your industry and headcount range. Specific examples matter more than general capability claims.

Pro Tips

During the sales process, ask to speak directly with the HR consultant who would actually be assigned to your account — not just the sales rep. That conversation will tell you more about service quality than any presentation will.

5. Scrutinize the Workers’ Comp Program at Scale

The Challenge It Solves

Workers’ comp is often a significant cost driver at 500 employees, particularly in industries with physical or operational risk. The structure of a PEO’s workers’ comp program — and how it handles claims — can have a real impact on your long-term cost exposure. Not all programs are built the same way.

The Strategy Explained

PEOs typically provide workers’ comp coverage through their master policy, which pools clients together. For smaller companies, that pooling can provide rate stability and access to coverage they might struggle to obtain independently. At 500 employees, the picture gets more nuanced.

Fixed-rate programs charge a consistent rate regardless of your specific claims history. Loss-sensitive programs (also called loss-sensitive or retrospective rating plans) tie your future premiums to your actual loss experience. At higher headcounts, a loss-sensitive structure can work in your favor if you have strong safety practices and a clean claims history — you pay less. It can also work against you if your loss history is poor.

Ask G&A Partners specifically how their workers’ comp program is structured, how your claims history affects your pricing, and what claims management resources they provide. A PEO that actively helps you reduce claims and manage return-to-work programs is worth more than one that simply provides coverage. For more context on how PEO workers’ comp programs work, see our PEO workers’ comp overview.

Implementation Steps

1. Request a clear explanation of whether G&A Partners’ workers’ comp program is fixed-rate or loss-sensitive for clients at your headcount, and how your claims history would affect future pricing.

2. Ask what claims management support they provide — dedicated claims coordinators, return-to-work programs, safety consulting. Understand what’s included versus billed separately.

3. If you have an existing workers’ comp policy, compare the total cost (premium plus any fees) against what G&A Partners proposes, factoring in your current experience modifier.

Pro Tips

If you’re in an industry with meaningful physical risk — construction, manufacturing, healthcare, logistics — this section of the evaluation deserves more weight than it typically gets. Workers’ comp can swing total PEO cost significantly at scale.

6. Map the Technology Stack Against Your Operational Needs

The Challenge It Solves

At 500 employees, HRIS functionality isn’t a feature — it’s infrastructure. Payroll accuracy, manager self-service, reporting depth, and compliance tracking all become operational necessities. If G&A Partners’ platform has gaps, you’ll end up building workarounds or paying for bolt-on tools. That cost needs to be in your comparison.

The Strategy Explained

G&A Partners uses a technology platform to support HR administration, payroll, and benefits management. The relevant question at your headcount isn’t whether the platform exists — it’s whether it actually handles the complexity your organization runs at.

Think through your specific operational requirements: Do your managers need self-service access for time-off approvals, performance reviews, and onboarding tasks? Do you need multi-state payroll with different tax configurations? Do you need robust reporting for HR metrics, headcount planning, or compliance audits? Does your current tech stack — accounting software, ATS, time tracking — need to integrate with the PEO’s platform?

PEOs sometimes oversell platform capabilities during the sales process. The only reliable way to assess fit is to request a live demo of the actual system — not a slide deck — and to walk through your specific use cases with someone who can show you how the platform handles them. For a detailed look at how platform limitations surface at this headcount with another provider, the Justworks PEO review for 500 employees is a useful parallel read.

Implementation Steps

1. Document your current technology requirements before any demo: payroll complexity, reporting needs, manager workflows, and integration requirements. Bring this list to the platform review.

2. Request a live system demo focused on your specific use cases. Ask to see multi-state payroll configuration, manager self-service workflows, and custom reporting capabilities.

3. Ask directly what integrations are available, what’s native versus requiring a third-party connector, and what the integration setup process looks like.

Pro Tips

Ask to speak with a current G&A Partners client of similar size and complexity about their day-to-day experience with the platform. Sales demos show the best-case scenario. A peer reference tells you what living with the system actually looks like.

7. Run a Parallel Comparison Before Committing or Renewing

The Challenge It Solves

The most common mistake companies make at 500 employees is evaluating a PEO in isolation. G&A Partners may be a reasonable option — but “reasonable” and “best value for your organization” are not the same thing. You can only know the difference if you’ve actually compared alternatives.

The Strategy Explained

Mid-market PEOs compete directly at the 500-employee tier. There are multiple providers with real capabilities at this headcount, and they price and structure their services differently. Some are stronger in specific geographies. Some have better technology. Some offer more flexible contract terms. Some have more competitive workers’ comp programs for specific industries.

Without a parallel comparison, you have no way to assess whether G&A Partners’ pricing is fair, whether their service model is competitive, or whether their contract terms are standard. You also have no negotiating leverage. PEOs know when they’re being evaluated against alternatives — and that knowledge affects what they’re willing to offer.

This is especially relevant at renewal. Companies in existing PEO contracts often renew by default because switching feels operationally complicated. At 500 employees, that inertia is expensive. Running a comparison doesn’t mean you’ll switch — it means you’ll know whether staying is actually the right financial and operational decision, or just the path of least resistance. If you’re weighing options at this scale, our guide to PEO services for 300 employees can help you understand how service structures shift as headcount grows toward the mid-market.

Implementation Steps

1. Identify two to three mid-market PEOs that actively serve companies in your headcount range and industry. Request proposals from each using identical information about your employee population, payroll, and service requirements.

2. Build a side-by-side comparison across total cost, service model, technology platform, contract terms, and co-employment structure. Don’t compare headline rates — compare total cost of ownership.

3. Use competing proposals as a negotiating tool with G&A Partners if you decide to stay. At 500 employees, you have real leverage — but only if you’ve done the work to know what the market looks like.

Pro Tips

Give each provider the same inputs and ask for proposals in a consistent format. Comparing apples to apples is harder than it sounds when PEOs structure their quotes differently. An independent PEO comparison service can help standardize the process and surface the real cost differences.

Your Implementation Roadmap

Evaluating G&A Partners at 500 employees is a different exercise than it was at 40. The financial exposure is larger, the operational dependencies run deeper, and the cost of a misaligned contract is genuinely hard to absorb at this size.

The seven strategies above give you a structured way to assess whether G&A Partners’ pricing model, service delivery, co-employment structure, and technology actually fit what your organization needs — not just whether they can technically serve a company your size. That’s a meaningful distinction.

If you’re approaching renewal, resist the default. Inertia is expensive at scale. The same evaluation framework applies whether you’re signing for the first time or deciding whether to stay — and the results of that evaluation should drive the decision, not administrative convenience.

One additional factor worth keeping in your evaluation: G&A Partners’ acquisition by GreenPoint Capital Partners is worth a direct conversation with their team. Ask how ownership has affected staffing, service delivery, and strategic direction. You deserve a straight answer before committing to a multi-year contract.

Before you renew your PEO agreement, compare your options. Most businesses overpay due to bundled fees and unclear administrative markups. An independent comparison breaks down pricing, services, and contract structures so you can make a smarter decision — and walk into any negotiation knowing what the market actually looks like at your headcount.
