How the score works

What matters for mid-sized companies

  1. Plan design flexibility

    Larger groups need options beyond a standard menu.

  2. Reporting and data access

    Finance and HR need data feeds and cost reporting.

  3. Cost comparison to in-house

    At this size, running HR and benefits directly may cost less.

  4. Integration with HRIS and accounting

    Duplicate systems add admin work.
