Two PEO providers are Insperity and TriNet. Both offer HR outsourcing solutions, but their services, pricing, and approach differ. If you’re an HR manager or business owner trying to choose between Insperity and TriNet, this article breaks down their key features, similarities, and differences to help you choose the right fit for your business. We also introduce Rippling, an innovative alternative that combines PEO services with advanced automation and flexibility for businesses of all sizes.

What is a PEO?

A Professional Employer Organization (PEO) is a company that helps businesses manage HR, payroll, benefits, and compliance. Instead of a business looking after these tasks in-house, they can outsource them to a PEO, which acts as a co-employer. This means the PEO technically shares responsibility for employees, handling a range of administrative tasks while the business keeps its control over the day-to-day operations.

PEOs typically provide:

• Payroll processing: Handling wages, tax withholdings, and direct deposits.
• Benefits administration: Offering health benefits, retirement plans, and various employee perks.
• HR support: Managing hiring, employee onboarding, and performance tracking.
• Compliance and risk management: Assisting businesses with following labor laws and workplace safety regulations.

Companies big and small use PEOs to save time, reduce liability, and offer better benefits without having to build an in-house HR team.

What is the difference between HCM and PEO?

Human Capital Management (HCM) systems and Professional Employer Organizations (PEOs) both serve HR functions but differ fundamentally in their approaches and services:​

• HCM systems: These are software solutions that enable businesses to manage various HR tasks internally. HCM systems typically include modules for recruiting, onboarding, performance management, payroll processing, and benefits administration. They provide tools for automating and streamlining HR processes but require the business' internal HR team to operate and manage these functions.​
• PEOs: PEOs offer outsourced HR services through a co-employment model, where the PEO becomes the employer of record for tax and compliance purposes. This arrangement allows the PEO to handle comprehensive HR responsibilities, including payroll, benefits, compliance, and risk management. Businesses benefit from the PEO's expertise and resources, potentially reducing administrative burdens and liability.

In summary, while HCM systems provide the tools for businesses to manage HR tasks internally, PEOs offer a partnership that outsources these functions, often providing a broader scope of services and assuming certain employer responsibilities.​

How much does Insperity cost?

​Insperity doesn’t publicly disclose its pricing, as PEO costs vary based on factors such as business size, selected services, and contract terms. The company typically charges a per-employee, per-month (PEPM) fee, rather than a percentage of total payroll. To obtain a customized quote, it’s necessary to contact Insperity directly.
