Oasis Outsourcing (Paychex Oasis brand) review and pricing

Legacy Oasis Outsourcing book, now serviced under Paychex Oasis brand.

By Paychex · Founded 1996 · West Palm Beach, FL · public

Oasis Outsourcing was, prior to its December 2018 acquisition by Paychex for $1.2B, one of the largest independent US PEOs. Paychex acquired Oasis and rebranded the combined PEO offering as Paychex Oasis (also marketed simply as Paychex PEO). The Oasis legacy book of customers continues to be serviced through the integrated Paychex PEO platform; some customers continue to interact with original Oasis service ops while others have been migrated to Paychex-native ops. The result is a credible mid-tier PEO with ESAC accreditation, IRS CPEO certification, and broad state licensing, but with the same uneven-integration trade-offs noted for Paychex PEO. New buyers in 2026 are routed to Paychex Oasis sales rather than a standalone Oasis brand; legacy Oasis customers should evaluate carefully whether their service experience reflects the original Oasis ops or the integrated Paychex platform.
