Running a small or mid-sized business means wearing many hats—and HR often tops the list of headaches. Between chasing changing labor regulations, scrambling to fill open roles, and scrambling to keep high performers engaged, founders and people leaders can end up feeling overwhelmed and under-resourced. Without a dedicated in-house HR team, compliance missteps, costly legal exposure, and talent gaps become very real threats to growth.
Outsourcing HR to a specialized consulting firm offers a smarter path. Instead of adding full-time headcount, you tap into seasoned experts who bring proven processes, proactive risk management, and scalable support at a fraction of the cost. From crafting compliant employee handbooks to designing competitive benefits programs, the right partner frees you to focus on strategic priorities.

Each profile highlights core services, pricing models, ideal use cases, and what sets these firms apart. Our selection criteria emphasized a strong SMB focus, comprehensive service suites, transparent pricing, solid reputations, and a client-first approach.
Whether you need end-to-end HR administration, on-demand strategic guidance, or technology-driven solutions, you’ll find the right match here. Keep reading to discover which outsourced HR ally can help you stay compliant, build a thriving team, and scale with confidence.

3. Insperity: Comprehensive PEO with Co-Employment Model
If you’re an SMB that wants big-company benefits without the HR headcount, Insperity’s Professional Employer Organization (PEO) offering might be your best bet. By becoming a joint employer, Insperity absorbs many of the administrative and compliance burdens—so you can focus on running your business, not wrestling with payroll or benefits renewals.
3.1. How the Co-Employment Model Works
Under Insperity’s PEO arrangement, you and Insperity share employer responsibilities. Technically, Insperity becomes the employer of record for tax purposes and benefits administration, while you retain control over day-to-day operations, culture, hiring, and firing decisions. This co-employment setup lets you:
- Tap into group health plans and retirement programs that are typically only available to larger firms
- Offload workers’ compensation, unemployment claims, and other HR-related risks
- Stay compliant with ever-shifting federal, state, and local labor laws
It’s a partnership designed to spread out risk and leverage scale—so your team gets robust benefits without you having to build everything from scratch.
3.2. Full Suite of Services
Insperity’s PEO package covers the HR essentials plus some extras you might not find in a basic outsourcing model:
- Payroll processing and tax filing
- Benefits administration (health, dental, vision, 401(k))
- Risk management and safety programs
- HR compliance audits and guidance
- Performance management tools and coaching support
- Employee relations assistance, including investigations and conflict resolution
All these services are delivered through a dedicated client experience team, giving you one clear point of contact for questions, escalations, and strategy discussions.

Best for SMBs that need enterprise-grade benefits and risk protection but don’t want to hire a full HR staff, Insperity shines when:
- You’re scaling headcount rapidly and need a turnkey HR solution
- Your industry demands specialized compliance programs (e.g., manufacturing, healthcare)
- You want offering-level health and retirement plans to attract and retain top talent
Pricing is based on a blended rate—usually expressed as a percentage of payroll—customized to your headcount, the services you select, and the complexity of your compliance needs (source: HR University). While there’s no one-size-fits-all cost sheet, most SMB clients find the PEO model more cost-effective than building an in-house benefits and payroll team from the ground up.
