The business defines the work to transfer
Start with recurring tasks and problems, then document headcount, locations, systems, benefits and internal owners. Providers propose a service model, implementation plan, team and price. The agreement should say who starts, approves, performs and checks each task.
HRO can be selective or comprehensive
Some companies outsource one process; others use a coordinated HRO team across several functions. HRO is not automatically the same as a PEO or employer-of-record arrangement. Compare the employment, payroll-tax, benefit, data and contract structure rather than relying on the label.
