Common Mistakes to Avoid
Several recurring procurement pitfalls appear across the providers listed, especially around onboarding load, governance complexity, and expectations for self-service and speed.
Overestimating self-serve speed for plan changes and complex setups
Wells Fargo Institutional Retirement & Trust and John Hancock Retirement can require slower coordination for non-standard changes because implementation and ongoing changes depend on service-team workflows rather than quick self-serve actions. Vanguard Retirement Plan Services and Empower can also require multiple steps for plan changes when workflow setup is complex for administrators.
Ignoring how governance and admin workflows depend on recordkeeper integration and roles
Aon and ADP Retirement Services both rely on admin workflows that depend on recordkeeping integration and assigned service roles, which can stretch timelines when multiple stakeholders must approve. Great-West Lifeco US can also face coordination requirements across multiple parties for sponsor integrations.
Choosing a provider that does not match participant education expectations
Sponsors expecting integrated participant investment education should avoid assuming that all providers deliver it in the participant journey because Fidelity Workplace Investing explicitly integrates investment education content with recordkeeping and plan statements. Empower reinforces education and guidance inside the participant experience but still can require guidance for advanced participant actions.
Selecting based only on digital usability without confirming operational processing coverage
Principal Financial Group and Great-West Lifeco US emphasize structured operational processing and managed administration depth, so sponsors should validate that operational workflows match plan activity needs like loans, distributions, and beneficiary maintenance. Mercer also emphasizes structured implementation and ongoing support, which can help reduce operational burden but can feel heavy for smaller sponsors with lean internal teams.
How We Selected and Ranked These Providers
We evaluated each provider on three sub-dimensions with explicit weights of capabilities at 0.4, ease of use at 0.3, and value at 0.3. The overall rating is the weighted average computed as overall = 0.40 × features + 0.30 × ease of use + 0.30 × value. Mercer separated itself through the capabilities dimension because it combines participant communications tied to retirement plan administration cycles with governance and compliance workflows that reduce sponsor operational burden. Providers like Great-West Lifeco US and ADP Retirement Services scored lower on the overall mix because operational rigor and administration coverage still carried tradeoffs like less compelling self-serve experiences or enterprise-focused user experiences that can feel less agile for small admins.
