Oasis — now part of Paychex and offered as Paychex PEO — is a good choice for small and mid-sized businesses with at least five employees that want payroll, large-group benefits, HR compliance and workers’ comp handled by one dedicated team. It’s a PEO, not a basic payroll service, so it costs considerably more: third-party estimates run about $100–$250 per employee per month. We rate it 4.0/5: excellent compliance and service, held back by quote-only pricing, a dated interface and add-on fees.
Oasis appears in our best payroll outsourcing companies rankings as the best PEO for small to mid-sized companies.
Oasis Is Now Part of Paychex
Paychex acquired Oasis Outsourcing, a West Palm Beach, Florida-based PEO, in 2018, making Paychex one of the largest PEO providers in the U.S. Oasis services are now delivered as Paychex PEO, and Paychex still maintains dedicated Paychex Oasis support lines for HR and PEO clients and their employees. If you’re searching for Oasis today, you’ll be quoted through Paychex.

Is Oasis a PEO or a payroll company?

Paychex PEO, which includes Oasis, generally requires a minimum of five employees. Confirm the minimum for your state and industry when requesting a quote.
Does Oasis require a contract?
Reviewers report a one-year minimum contract that can be cancelled with 30 days’ written notice, though an early termination fee may apply. Ask for contract length, renewal terms and termination fees in writing before signing.
Is Oasis better than ADP TotalSource?
Both are large, established PEOs. Oasis offers Paychex’s dedicated payroll and HR team model, while ADP TotalSource is the largest PEO and fits companies already using ADP products. Pricing for both is quoted, so compare proposals for your headcount and benefits needs.

Insperity is known for high-touch service and training, while Oasis offers Paychex’s scale and a dedicated payroll and HR team. Both price by quote, often as a percentage of payroll, so compare total cost including benefits.
Should I choose a PEO like Oasis or a regular payroll service?
Choose a PEO like Oasis if you want large-group health benefits, outsourced HR compliance and workers’ comp help. Choose a payroll service if you mainly need payroll and tax filing, since it typically costs far less, often under $10 per employee per month for small businesses.
Is Oasis good for small businesses?
Oasis is a good fit for growing small businesses with roughly 5 to 49 employees that want better benefits and HR support than they could get alone. Very small teams that only need payroll may find a payroll service such as Gusto or OnPay more cost-effective.
