Paychex acquired Oasis Outsourcing in 2018 for $1.2 billion in cash. Oasis Outsourcing was an ESAC-accredited human resources services company based in Florida that offered services in human resources, employee benefits, and payroll processing. The acquisition was about building revenue, and Paychex aimed to grow its human resource outsourcing capability and extend its technology to a new client base as part of the acquisition. While Oasis initially operated as its own entity, it is now fully part of the Paychex brand as one of the available solutions in "Paychex HR."
