Test a realistic growth scenario
Ask what changes if the business adds a location, pay group, benefits plan or hiring surge. The provider should explain configuration, staffing, implementation work, timing and cost. Scalability is an operating capability, not simply a platform claim.
Require continuity and control
Confirm backup service coverage, exception handling, permissions, data exports and a staged change process. Review minimums, annual increases, renewal and exit help. A scalable model should adapt without forcing the business to sacrifice records, oversight or a practical rollback.
