## Frequently Asked Questions

### What industries does TriNet specialize in?
TriNet has built industry-specific HR packages for technology companies, professional services firms, financial services, retail businesses, and nonprofits, with benefit designs and compliance guidance tailored to the unique workforce needs of each vertical.

### How did TriNet's acquisition of Zenefits affect its product offerings?
TriNet acquired Zenefits in 2022, adding a modern cloud-based SMB HR software platform to its portfolio and enabling the company to serve small businesses that want HR software without a full PEO co-employment arrangement.

### What is the difference between TriNet's PEO model and standalone payroll software?
TriNet's PEO model involves co-employment, meaning TriNet shares legal employer responsibilities with client companies, which allows TriNet to provide group benefits rates and take on employment compliance liability. Standalone payroll software only processes payroll without these co-employment protections.

### What is TriNet and what PEO services does it provide?
TriNet is one of the largest Professional Employer Organizations (PEOs) in the US, providing small and mid-size businesses with co-employment services that include payroll processing, employee benefits administration, HR compliance support, and risk management — allowing SMBs to access Fortune 500-quality benefits and HR infrastructure.

### How does TriNet's co-employment model work?
Under TriNet's co-employment arrangement, TriNet becomes the employer of record for payroll and benefits purposes while the client company maintains day-to-day control over work and management decisions, allowing TriNet to pool employees across its client base to negotiate large-group benefits rates.

### What industries does TriNet specialize in?
TriNet serves multiple industries with specialized HR knowledge, including technology companies, life sciences, professional services, financial services, and non-profits, providing industry-specific guidance on benefits, compliance, and HR practices relevant to each sector's unique workforce needs.

### What employee benefits does TriNet provide access to?
TriNet provides access to comprehensive benefits packages including medical, dental, and vision insurance from major carriers at group rates, 401(k) plans, commuter benefits, supplemental insurance, and other employee perks that small businesses could not typically negotiate independently.

TriNet provides guidance on federal and state employment law compliance including ACA, FLSA, FMLA, EEO, and state-specific requirements, with HR advisors available to help client companies navigate complex employment situations, reducing the compliance risk and administrative burden on small business owners.
