What to look for

If your priority is affordable employer contributions + good system integration, ask vendors about:

• Support for Workday, ADP, Oracle HCM, UKG, SAP SuccessFactors, Paychex, or Ceridian
• Whether they support EDI feeds, API integrations, or file-based enrollment
• How they handle new hire events, life events, terminations, COBRA, and deductions
• Whether employer contribution funding is fixed, defined-contribution, or level-funded

Practical note

The “best” option often depends more on the plan funding model and your HR/payroll stack than the brand name. A platform that’s cheap upfront can be expensive operationally if integrations are weak.
