Which is best for payroll outsourcing and HR service ADP or TriNet?

I used their payroll services a few years back But now I migrated to Spectra Outsource Solutions’s payroll services.

My vote is for ADP. I used their payroll services a few years back But now I migrated to Spectra Outsource Solutions’s payroll services. Earlier I was paying a heavy amount to ADP but now I am paying only 50 rupees per employee for the payroll processing.

Before opting anyone’s services you can ask for the trials.
