Start with service and support
Compare onboarding, payroll, benefits, records, compliance processes and manager guidance against one written scope. Ask who performs each task, who covers absences, what response expectations apply and which work costs extra.
Review technology and contract protections
Confirm the system of record, integrations, permissions, exports, reporting and security documentation. Then compare implementation responsibilities, renewal, price changes, termination assistance and data access at exit. Score only what appears in the proposal and agreement.
