TriNet is a strong option for HR and payroll for small- and medium-sized companies.

The TriNet team is prompt and helpful. They are almost immediately available during business hours and respond quickly when emailed outside of regular times. The portal is very useful in finding information and updating policy (for example, changing the compensation of an employee).

TriNet offers an excellent portal for both employers and employees. As the former, I used it to survey my payroll, institute benefits, and other HR policies, and generate reports (such as SBA reports). As an employee, it seamlessly took me through the benefits enrollment process, generation of W-2, and other common HR tasks.

I had a chance to interact with TriNet as a company founder and as an employee in two other start-up companies. In all cases, their offering has been above average and their service was cordial, prompt, and efficient. In addition to payroll and benefits, I utilize TriNet on a regular basis to address HR questions, such as the institution of a parental leave policy and for questions regarding challenging hiring choices (such as hiring an American expatriate).
