About Oasis, a Paychex Company

Oasis, a Paychex Company, is a full-service Professional Employer Organization formed through Paychex's 2018 acquisition of Oasis Outsourcing — one of the largest privately held PEOs in the country at the time, serving over 8,400 clients. Originally founded in 1996 in West Palm Beach, Florida, Oasis Outsourcing had built a strong reputation for co-employment expertise before being integrated into the Paychex ecosystem. Today, Oasis operates as Paychex's dedicated PEO brand, combining Oasis's deep co-employment heritage with Paychex's technology platform, Paychex Flex, and its institutional payroll infrastructure. The Oasis model provides dedicated HR, payroll, benefits administration, workers' compensation, risk management, and compliance services to small and mid-sized businesses. Clients benefit from both the personalized service culture of Oasis and the enterprise-scale benefits buying power of Paychex's 2.5M+ worksite employee pool. Oasis serves businesses across all 50 states with IRS CPEO certification and particular strength in Florida and the Southeast.
