TriNet

TriNet is a professional employer organisation providing payroll, employee benefits, HR support, HR compliance and HR automation through a platform with personalised support. It offers a full-service PEO alongside HR Plus, a lighter arrangement covering outsourced HR, payroll processing and payroll tax compliance without the full co-employment relationship.

Understanding what a PEO actually is decides whether this fits. In a full PEO the provider becomes a co-employer of record, which is what lets a small company access benefit plans priced for a much larger workforce, because employees are pooled across every client. That pooling is the entire economic argument, and it is unavailable to a company buying payroll software alone.

The co-employment relationship is also the reservation to weigh. It is a legal arrangement affecting employer of record status, liability and how an exit is handled, and unwinding it later is materially harder than changing a software vendor.

HR Plus exists for exactly that hesitation, giving a company outsourced payroll and HR administration without entering co-employment, at the cost of the benefits pooling that made the PEO attractive. A company should decide which of the two it is actually buying before comparing prices, because the two tiers solve different problems and only one of them changes what an employee receives.
