Payroll powerhouse with nationwide PEO infrastructure (includes Paychex Oasis)
Our take
Paychex PEO is the reliable workhorse of the PEO industry. They're not the most exciting platform and they're not the cheapest, but their multi-state payroll and tax compliance infrastructure is rock solid, especially valuable if you already use Paychex payroll. The legacy Oasis brand is now fully under the Paychex HR umbrella; if you were an Oasis customer, you're a Paychex customer. Always request a full fee schedule upfront, add-ons are common.
