TriNet does not publish standard dollar amounts for its current PEO or HR Plus services. Both offerings use custom per-employee-per-month pricing, commonly abbreviated as PEPM, and businesses must contact TriNet to obtain a quote.
For TriNet PEO, independent 2026 reports commonly place the administrative fee at approximately $100–$150 per employee per month. That is an unofficial estimate, not a TriNet rate card. Actual quotes can fall outside that range based on headcount, location, industry, requested services, and other account or underwriting factors.
The administrative fee is also only one part of the total TriNet cost. Employee wages, employer payroll taxes, health insurance premiums, workers’ compensation costs, and optional services are separate. That distinction matters because TriNet PEO offers a broader HR outsourcing arrangement than a standard payroll software subscription.
TriNet’s current product structure is also different from what readers may see in older TriNet Zenefits reviews. Its public website now emphasizes two primary U.S. offerings:
TriNet PEO, which creates a co-employment relationship
TriNet HR Plus, an administrative services organization, or ASO, that does not use co-employment
This guide explains how each model is priced, what TriNet’s administrative fee may cover, which additional expenses buyers should examine, and how TriNet pricing compares with published Gusto payroll plans.
TriNet pricing at a glance
Product or platform | Service model | Official pricing | Public estimate | Co-employment? |
TriNet PEO | PEO with payroll, benefits administration, HR support, risk-mitigation services, and HR technology | Custom PEPM quote | Approximately $100–$150 PEPM from third-party reports | Yes |
TriNet HR Plus | ASO with HR technology and configurable payroll, tax, benefits administration, and HR support | Custom PEPM quote | No sufficiently reliable current public range | No |
TriNet HR Platform | HR technology platform included with HR Plus and associated with the former Zenefits platform. | No separate current public price confirmed. | Current standalone availability is not publicly described; older Zenefits price cards should not be treated as current | No |
Important: The TriNet PEO estimate covers the administrative fee only, not wages, payroll taxes, insurance premiums, workers’ compensation premiums, or any optional services. Actual quotes vary.
How TriNet pricing works
TriNet uses a flat administrative fee for each active worksite employee rather than charging its core PEO administrative fee as a percentage of payroll.
The formula is:
Monthly TriNet administrative fee = active employees × quoted PEPM rate
TriNet’s official pricing page illustrates this method with a hypothetical $150 PEPM rate. At that example rate, 20 employees would produce a $3,000 monthly administrative fee. TriNet does not present $150 as a standard or guaranteed rate.
What PEPM means
PEPM stands for per employee per month. If headcount increases, the monthly administrative charge generally increases. If headcount decreases, it generally falls.
A PEPM model can be easier to forecast than a percentage-of-payroll fee because giving an employee a raise does not automatically increase the administrative fee. The total invoice can still change when:
The number of active employees changes
The business adds or removes services
Insurance rates or enrollment change
Workers’ compensation costs change
Payroll-tax obligations change
The customer renews or renegotiates its agreement
TriNet says its quotes depend on factors such as company size, geographic footprint, industry, and the complexity of the requested services.
What a PEO is
A professional employer organization provides payroll and HR services through a co-employment relationship.
Under TriNet’s PEO model, TriNet generally acts as employer of record for payroll-tax purposes and administers designated HR functions under the service agreement. The client business continues to direct employees’ work and retains control over hiring, termination, compensation, company culture, and day-to-day operations.
TriNet PEO services can include:
Payroll processing
Payroll-tax calculation, withholding, remittance, and filing
Benefits administration
Access to PEO-sponsored benefit options
Workers’ compensation administration
Employee onboarding tools
HR technology
HR guidance
Risk-mitigation and compliance support
The exact allocation of responsibilities depends on the customer’s agreement. Using a PEO does not eliminate the client company’s legal, tax, benefits, or employment responsibilities.
Why TriNet requires a quote
A single published price would not account for all the variables that shape a PEO relationship. TriNet evaluates factors such as:
Employee count
Work locations and states
Industry
Requested services
Benefits selections and enrollment
Workers’ compensation exposure
Payroll and tax complexity
Support requirements
Optional tools or specialist services
A quote allows TriNet to price those factors, but it also means buyers cannot determine their exact TriNet cost from the website alone.
TriNet products and pricing
TriNet’s current public product structure centers on TriNet PEO and TriNet HR Plus. Both require prospective customers to request a quote.
Offering | What it is | Pricing structure | Key distinction |
TriNet PEO | Full-service HR outsourcing through co-employment | Custom PEPM administrative fee | TriNet generally processes payroll under the PEO’s tax ID and may sponsor employee benefit plans |
TriNet HR Plus | ASO combining HR technology with configurable outsourced services | Custom PEPM fee based on headcount and service level | The client remains the employer of record, and payroll uses the client’s tax ID |
Payroll Pro | Additional payroll and payroll-tax expertise for HR Plus | Not publicly disclosed | Adds hands-on payroll and payroll-tax specialists |
People Pro | Additional HR expertise for HR Plus | Not publicly disclosed | Adds dedicated HR support, talent, and organizational consulting |
TriNet Global | Global-workforce support is available with TriNet PEO | Available only as a PEO add-on; pricing is not publicly disclosed | Not presented as a standalone TriNet product |
Does TriNet still have Essentials, Growth, and Zen plans?
TriNet’s current official product and pricing pages do not list Essentials, Growth, and Zen as PEO pricing tiers.
Those names appear in older reviews of the software historically associated with TriNet Zenefits. Applying those older plan names or prices to TriNet’s current PEO offering would mix separate products and service models.
TriNet acquired Zenefits to expand its software-based HR technology capabilities beyond its traditional PEO offering. TriNet now markets HR Plus as its ASO service and includes the TriNet HR Platform, associated with the former Zenefits platform, as part of that offering.
Buyers should request a current HR Plus configuration instead of relying on an older Zenefits price card.
How much does TriNet PEO cost?
TriNet’s official answer is that pricing is customized. It does not publish a minimum, maximum, or standard administrative rate. Most third-party estimates put the price between $100 and $150 per employee per month.
It is not a guaranteed starting price. A buyer’s quote may be lower or higher, and the sources do not establish a universal set of services across the entire range.
Estimated TriNet cost by headcount
The following examples apply the third-party $100–$150 PEPM range.
Employees | Estimated monthly administrative fee | Estimated annual administrative fee |
10 | $1,000–$1,500 | $12,000–$18,000 |
25 | $2,500–$3,750 | $30,000–$45,000 |
50 | $5,000–$7,500 | $60,000–$90,000 |
Assumptions: Each example multiplies the active employee count by the unofficial $100–$150 PEPM range. The figures exclude wages, employer payroll taxes, health and other insurance premiums, workers’ compensation premiums, optional add-ons, implementation expenses, and contract-specific charges.
These calculations should be used only for preliminary budgeting. A written TriNet proposal is necessary to determine the actual price.
What the TriNet PEO administrative fee covers
TriNet says its PEPM administrative fee generally covers the services involved in operating the PEO relationship.
Service | General pricing treatment |
Payroll processing | Generally included in the PEO administrative fee |
Payroll-tax administration | Generally included |
Actual employer payroll taxes | Separate business expense |
HR expertise | Generally included, with exact service level depending on the agreement |
Benefits administration | Generally included |
Medical, dental, and vision premiums | Separate |
Workers’ compensation administration | Generally included |
Workers’ compensation insurance cost | Separate |
HR technology access | Generally included |
Employee onboarding tools | Generally included |
Background checks and drug screening | May be separately priced |
Premium learning content | May be separately priced |
Certain risk-mitigation services | May be separately priced |
Global workforce services | Separate PEO add-on |
“Included” does not mean every customer receives the same support, plan choices, response times, or optional modules. Buyers should compare the scope listed in their proposal with the services they currently receive or would otherwise purchase separately.
Additional TriNet costs to budget for
A TriNet PEO invoice can include substantially more than its administrative PEPM fee. The following expenses are either separate from the administrative fee or require confirmation in the individual quote.
Employee benefit premiums
Medical, dental, and vision premiums are separate from the PEPM administrative charge. Total benefit cost depends on:
Available plans and carriers
Employer contribution
Employee and dependent enrollment
Coverage level
Location
Renewal rates
The reviewed official sources do not establish that TriNet applies a universal 15%–25% markup to health insurance. Buyers should ask TriNet to separate the plan or carrier cost, employer contribution, employee contribution, and any administrative charges in the proposal.
TriNet also offers Open Market Solutions, which may allow a PEO customer to retain an existing benefits broker. Availability and terms can depend on the customer’s arrangement, so businesses should confirm how broker responsibilities, carrier access, administration, and fees would work in their specific proposal.
Employer payroll taxes
TriNet can calculate, withhold, remit, and file applicable payroll taxes for payroll processed through its platform. The underlying employer tax liability remains a separate business expense.
These costs can include:
Employer Social Security and Medicare taxes
Federal unemployment tax
State unemployment tax
State or local employer taxes
TriNet says that applicable tax-related charges may decrease when an employee reaches a statutory wage threshold. Buyers should review how taxes and administrative fees are itemized on the proposal and invoice.
Workers’ compensation
Workers’ compensation administration is part of the PEO service, but the insurance cost is separate. Rates can vary by payroll, employee classification, location, industry, claims experience, and coverage arrangement.
The reviewed sources do not verify a universal TriNet workers’ compensation markup. Compare the quoted policy cost, employee classifications, fees, assessments, and coverage with an independent option to evaluate the total cost.
Optional screenings, learning, and risk services
TriNet identifies several services that may cost extra, including:
Background checks
Drug screening
Premium learning-management content
Certain risk-mitigation services
Ask for an itemized list of mandatory and optional charges. The presence of a service on TriNet’s platform does not necessarily mean it is included in the base PEPM fee.
Implementation or onboarding charges
TriNet notes that many PEOs charge a one-time onboarding or implementation fee, but its public pricing page does not specify a single TriNet implementation fee.
The quote should specify:
Whether implementation is free or separately billed
What data conversion is included
Whether benefits set up extra costs
Whetherthe payroll-tax account works costs extra
What happens if the implementation is delayed or canceled
Contract, renewal, and termination costs
Public TriNet pages do not establish one universal contract length, cancellation window, renewal increase, or early-termination charge for all PEO or HR Plus customers.
Review the applicable proposal, service agreement, order form, and renewal notice for:
Initial term
Renewal term
Auto-renewal
Notice deadline
Early-termination charge
Minimum administrative charge
Minimum employee count
Final invoice
Benefits termination
Data access after termination
A customer-reported fee or cancellation experience should not be treated as a standard TriNet policy.
How much does TriNet HR Plus cost?
TriNet HR Plus also uses custom PEPM pricing. TriNet says the rate depends on employee count and the selected service level, but it does not publish a current dollar amount.
HR Plus is an ASO, not a PEO. The client business remains the employer of record, payroll generally runs under the client’s tax ID, and TriNet does not sponsor the benefits in the same way a PEO may.
The offering combines the TriNet HR Platform with services involving areas such as:
Payroll
Payroll-tax administration
Benefits administration
HR support
Recruiting
Compliance guidance
Employee onboarding and offboarding
Time, attendance, and PTO
Document management
Reporting
TriNet also markets configurable support options:
Payroll Pro: Dedicated payroll and payroll-tax specialists, pay-run review, tax-account setup assistance, jurisdiction review, and related services
People Pro: Dedicated HR expertise, employee lifecycle guidance, policy support, compensation benchmarking, workforce strategy, and organizational consulting
The public pricing pages do not disclose whether either option has a separate fee, minimum headcount, or required term.
PEO versus HR Plus
Question | TriNet PEO | TriNet HR Plus |
Does TriNet publish the rate? | No | No |
Pricing model | Custom PEPM | Custom PEPM |
Co-employment | Yes | No |
Payroll tax ID | Generally, the PEO’s tax ID | Client’s tax ID |
PEO-sponsored benefits | May be available | No, the client maintains or sources benefits |
Benefits administration | Included in the PEO service | Available through the HR Plus platform and service configuration |
Workers’ compensation | PEO administration and coverage structure | Depends on selected services and client arrangements |
HR technology | Included | Included |
Best comparison | Other PEO quotes | ASO, outsourced HR, and payroll-plus-service quotes |
HR Plus may be the more relevant TriNet option for a business seeking outsourced HR services without entering into a co-employment relationship. Its cost cannot be responsibly estimated from TriNet’s current public materials.
TriNet pricing versus Gusto pricing
TriNet PEO and Gusto are not equivalent products.
TriNet PEO combines software with a co-employment arrangement, PEO-sponsored access to benefits, workers’ compensation administration, HR expertise, payroll tax administration, and risk mitigation services. Gusto’s published plans are payroll and HR software subscriptions without the TriNet PEO co-employment structure.
The price comparison therefore shows the difference between two service models, not the cost of identical packages.
Pricing category | TriNet PEO | Gusto |
Published subscription price | No | Yes |
Core pricing model | Custom PEPM | Monthly base fee plus per-person fee |
Public starting price | Not disclosed | Simple: $49 plus $6 per person |
Third-party estimate | Approximately $100–$150 PEPM for the administrative fee | Not needed for standard plans |
25-person cost | Estimated $2,500–$3,750 monthly administrative fee | $199 Simple; $380 Plus; $730 Premium |
Co-employment | Yes | No |
Payroll taxes | Administration included: tax liability separate | Filings and payments included with payroll plans; tax liability separate |
Benefits | PEO-sponsored options and administration; premiums separate | With Gusto as broker, the employer pays premiums without a separate Gusto administration charge |
Existing benefits broker | TriNet’s Open Market Solutions may allow a PEO customer to retain its broker; availability and terms depend on the arrangement | Eligible broker integration costs $6 per eligible employee for Simple and Plus customers and is included for Premium customers |
Workers’ compensation | Administration included; insurance cost separate | Pay-as-you-go coverage starts at $14 per month; actual premiums vary by business, and an additional integration fee may apply |
Contract information | Agreement-specific | Month-to-month; cancel anytime |
Setup | Quote-specific; no universal public fee confirmed | Account setup is free |
HR expertise | Included according to the PEO service scope | Certified HR experts are included in Premium or available through an add-on for Simple and Plus |
Gusto’s pricing plans
Gusto plan | Base fee | Per-person fee | Cost for 25 people |
Simple | $49 per month | $6 per month | $199 per month |
Plus | $80 per month | $12 per month | $380 per month |
Premium | $180 per month | $22 per month | $730 per month |
Contractor Only | $35 per month regular base price | $6 per contractor | Depends on the contractors paid |
How to interpret the price difference
The price difference is large because the underlying services are different.
A business that mainly needs payroll, tax filing, onboarding, benefits administration, time tracking, and selected HR tools may not need to pay for a PEO relationship. Published software pricing may make its monthly cost easier to forecast.
A business seeking co-employment, PEO-sponsored benefit plans, workers’ compensation administration, deeper HR outsourcing, and an integrated service team may view the higher TriNet PEO fee differently.
Compare the two options by identifying the cost of replacing everything included in the PEO proposal, not by comparing the PEPM administrative fee with payroll software alone.
PEO versus ASO versus payroll software
Model | Employer relationship | Typical services | Pricing approach | May suit businesses that… |
PEO | Co-employment | Payroll, benefits, workers’ compensation, HR guidance, compliance support, and technology | PEPM or percentage of payroll | Want to outsource a broad set of employer-administration functions |
ASO | Client remains the sole employer | Payroll, HR administration, tax services, benefits administration, and technology | Usually, custom PEPM or service-based pricing | Want service support without PEO co-employment |
Payroll and HR software | Client remains the employer | Payroll, tax filing, records, onboarding, benefits administration, and optional HR tools | Published or quoted software subscription | Can manage more HR decisions internally and wants modular costs |
A PEO may make sense when:
The business wants to outsource a broad set of payroll and HR administration functions.
PEO-sponsored benefit options are an important part of the buying decision.
The company operates in multiple states and wants ongoing HR guidance.
Internal staff does not have the time or expertise to administer payroll, benefits, workers’ compensation, and recurring HR processes.
The company accepts co-employment and a contract-based service model.
An ASO or payroll platform may make more sense when:
The business wants to retain its current benefits broker or insurance arrangements.
It wants payroll processed under its own tax ID.
Its HR team can retain responsibility for workforce decisions and vendor management.
It wants published software pricing or a more modular service package.
Its needs are primarily payroll, tax filing, onboarding, time tracking, and benefits administration.
The decision should be based on total service scope, not headcount alone. A 15-person business with complex multi-state benefits and no HR staff may value a PEO more than a 75-person business with an established HR department.
How to evaluate a TriNet quote
Request an itemized proposal that separates the administrative fee from pass-through and insurance costs.
At minimum, verify:
Administrative PEPM rate: Confirm which employees count as active worksite employees and whether a minimum monthly charge applies.
Included services: Identify the payroll, tax, HR, benefits, compliance, support, and technology services included.
Benefit premiums: Separate employer contributions, employee deductions, dependent coverage, and administrative charges.
Existing broker arrangements: Confirm whether TriNet Open Market Solutions or another arrangement would allow the business to retain its broker.
Workers’ compensation: Review employee classifications, premiums, assessments, and claims-related services.
Payroll taxes: Determine how federal, state, and local tax liabilities appear on the invoice.
Add-ons: Price screenings, learning content, recruiting, global services, premium support, and specialist services.
Implementation: Confirm data-conversion support, fees, responsibilities, and deadlines.
Agreement term: Review the initial term, renewal process, notice deadline, and auto-renewal language.
Termination: Confirm possible fees, final payroll responsibilities, benefits end dates, and access to historical data.
Renewal pricing: Ask which components can change at renewal and when TriNet must provide updated rates.
Service guarantees: Identify any response-time, filing, or support commitments included in the agreement.
Exit requirements: Determine how payroll histories, tax documents, employee records, benefits data, and accounting reports can be exported.
Use the same employee census, locations, payroll schedule, benefits assumptions, and requested services when comparing TriNet with another PEO. Otherwise, the quotes will not represent equivalent coverage.
Is TriNet worth the cost?
TriNet may provide value when a business needs more than payroll software.
Its PEO combines payroll, payroll tax administration, benefits access, workers’ compensation administration, HR technology, onboarding tools, HR guidance, and risk mitigation support. Replacing those functions separately could require several vendors or additional internal staff.
The PEO model may be especially relevant for businesses that:
Have little internal HR capacity
Need ongoing payroll and HR support
Want access to PEO-sponsored benefit options
Operate across multiple jurisdictions
Prefer to consolidate HR administration with one provider
Are comfortable with co-employment
TriNet may be more than a business needs when it already has a benefits broker, workers’ compensation coverage, HR staff, and straightforward payroll requirements. In that situation, HR Plus, another ASO, or payroll and HR software may provide a more targeted service model.
Pricing transparency is an important trade-off. TriNet explains its PEPM structure but does not disclose a standard dollar rate. A business cannot accurately budget for TriNet until it has received and reviewed a proposal.
The value judgment should therefore consider:
The administrative fee
Insurance costs
Internal HR labor was avoided
The quality and scope of specialist support
Benefits choices
Workers’ compensation arrangements
Contract flexibility
Implementation effort
Costs and operational work required to leave the PEO later
Who TriNet may be best suited for
Based on its current service structure, TriNet may be worth evaluating for:
Small and midsize employers seeking a full PEO
Businesses without a large internal HR department
Multi-state employers needing payroll and HR guidance
Companies that place significant value on benefits access
Organizations seeking payroll, benefits, HR support, and workers’ compensation administration from one provider
Businesses that want an ASO through HR Plus rather than co-employment
A different model may be more practical for:
Businesses needing only payroll and basic HR software
Companies that require a published price before speaking with sales
Employers are satisfied with their existing broker and insurance arrangements
Businesses seeking month-to-month software without a PEO agreement
Companies with an established HR department that can manage most administrative work internally
Businesses comparing TriNet with payroll software can review Gusto’s published plans to determine whether a software subscription covers their needs before requesting a full PEO quote.
TriNet pricing FAQs
How much does TriNet cost per employee?
TriNet does not publish a standard rate. Independent 2026 sources estimate the TriNet PEO administrative fee at approximately $100–$150 per employee per month. Benefits, employer taxes, workers’ compensation premiums, and optional services are separate, and actual quotes may fall outside that range.
Does TriNet charge a percentage of payroll?
TriNet says its PEO administrative charge uses flat PEPM pricing rather than a percentage of payroll. The administrative fee therefore does not automatically increase when employees receive raises. Payroll taxes, insurance premiums, wages, and other variable expenses remain separate.
Is TriNet pricing transparent?
TriNet explains its PEPM structure and says its quote includes line-item costs, but it does not publish standard dollar rates. Businesses must provide company information and speak with TriNet before receiving an estimate.
What TriNet plans are available?
TriNet’s current public site emphasizes TriNet PEO and TriNet HR Plus. HR Plus can be enhanced with Payroll Pro and People Pro services. Current official pages do not list Essentials, Growth, and Zen as TriNet PEO pricing tiers.
What is the minimum company size for TriNet?
TriNet says it works with businesses ranging from five to more than 1,000 employees and confirms that its PEO has a minimum worksite-employee requirement. It does not publicly establish one universal minimum for every quote or product configuration.
Can a business cancel TriNet at any time?
The reviewed public sources do not establish a universal cancel-anytime policy for TriNet PEO or HR Plus. Customers should review their service agreement, order form, renewal notice, required notice period, and any termination provisions before signing or canceling.
Does TriNet mark up employee benefits?
TriNet says medical, dental, and vision premiums are separate from its PEO administrative fee. The reviewed official sources do not verify a universal percentage markup. Buyers should request an itemized comparison of premiums, employer contributions, employee contributions, and administrative charges.
TriNet’s Open Market Solutions may also allow some PEO customers to retain their existing broker, depending on the arrangement.
How does TriNet pricing compare with Gusto?
TriNet PEO uses custom PEPM pricing and includes a co-employment relationship, as well as broader outsourced HR services. Gusto publishes payroll software plans starting at $49 per month, plus $6 per person. The lower software price does not provide an equivalent PEO service package.
Sources
Pricing and structure are drawn from TriNet's own pages (the PEPM model, the $150 example, the PEO vs. HR Plus distinction, and TriNet Global). TriNet does not publish dollar rates for PEO or HR Plus, so the $100–$150 PEPM figure is an unofficial third-party estimate only.

Disclaimer
Pricing is accurate as of June 2026. TriNet does not publish standard rates for TriNet PEO or HR Plus; both use custom per-employee-per-month (PEPM) pricing and require a quote. The $100–$150 PEPM figure is an unofficial third-party estimate of the administrative fee only — not a TriNet rate card — and actual quotes may fall outside it. The administrative fee excludes employee wages, employer payroll taxes, health and other insurance premiums, workers' compensation premiums, implementation, and optional services, all of which are separate. TriNet PEO is a co-employment arrangement and is not equivalent to payroll software, so it should be compared against other PEO quotes using the same census and service scope.
