TipBottom line

You should consider outsourcing your HR functions if you spend too much time handling HR problems or if your industry subjects your company to liability risks.

TriNet vs. Justworks Comparison

Here’s how TriNet and Justworks compare in pricing, ease of use, customer service and standard PEO services

Pricing and Plans

Fitting your PEO into your business budget is crucial. Here’s how TriNet and Justworks handle pricing. 

TriNet Pricing

Like many PEOs, TriNet does not list its pricing online. Instead, it provides custom quotes based on each client’s needs. Depending on your preferences, TriNet’s pricing model could be a benefit or drawback.

Here is some notable TriNet pricing information:   

  • TriNet charges on a per-employee-per-month basis, similar to other PEOs.
  • You must have a minimum of five employees to work with TriNet. This requirement is also commonplace in the PEO industry.
  • We like that TriNet users aren’t locked into long-term plans. You can cancel anytime by submitting a 30-day written notice.
TipBottom line

If you want a TriNet HR solution without the PEO model, check out Zenefits by TriNet, an HRO service with onboarding and other employee-centric features. Read our review TriNet for more information.

Justworks Pricing

Justworks transparently lists its pricing online – a rarity in the industry. It offers two PEO plans: 

  • Basic: $59 per employee per month up to your 49th employee; your 50th employee onward costs $49 per employee per month. The Basic plan includes payroll, employee benefits, HR tools and compliance assistance.
  • Plus: $99 per employee per month up to your 49th employee; your 50th employee onward costs $89 per employee per month. This plan includes everything in Basic, plus employee benefits like medical, dental, and vision insurance; COBRA administration; health advocacy services; and health savings and flexible spending accounts.

Here is some notable Justworks pricing information:   

  • Healthcare benefits and workers’ compensation incur additional fees (this is industry standard).
  • You must have a minimum of two employees before signing up for Justworks. This requirement is lower than that of many other PEOs.
  • Like TriNet, Justworks doesn’t lock users into long-term plans. You can cancel anytime by submitting a 30-day written notice.


Justworks wins this round with its transparent pricing and reasonable rates. We like that business owners can get a quick assessment of their costs and services. The two-employee minimum also impressed us; this is an excellent option for very small companies. Additionally, users can easily switch from Basic to Plus if their needs change. Although TriNet’s customized pricing and plans deliver personalized solutions, costs can add up – and your price won’t be clear until you contact a representative.

Ease of Use

TriNet Ease of Use

  • User-friendliness: TriNet is a user-friendly platform. When we tested the software, we were pleased with its layout and functionality.

  • Mobile apps: The Justworks mobile apps are also very easy to use. The apps rate highly on Apple’s App Store and Google Play.

  • Credentials: TriNet is a certified professional employer organization (CPEO). It is also accredited by the Employer Services Assurance Corporation (ESAC) and the IRS, and has an A+ Better Business Bureau (BBB) rating. 

Justworks Customer Support

  • Support options: Support is available by phone, email, web chat, Slack and text. Companies with 15 or more employees are provided with a dedicated account manager.
  • Online resources: Justworks has online resources like blogs, videos, webinars and a help center.
  • Credentials: Justworks is a CPEO. It is also accredited by the ESAC and the IRS. It has a C- rating with the BBB.


We like that both companies provide excellent customer support. However, TriNet wins this category by a slight margin. In addition to its online resources and general support, TriNet provides industry-specific support – a significant benefit for getting HR compliance questions answered. We also like that TriNet has an A+ rating with the BBB, compared to Justworks’ C- rating. While this rating isn’t always indicative of the service you’ll receive from a company, it’s worth noting.
