Small teams often start selectively
A business without a dedicated HR employee may begin with onboarding, payroll coordination, employee records or access to an adviser. The goal is to cover recurring gaps without buying services the company will not use. Ownership should stay clear even when one person wears several internal roles.
Larger organizations may outsource around an internal team
Midsize employers often keep HR leadership while outsourcing high-volume administration, technology or specialist work. Compare current headcount, growth, work locations, pay groups, benefits and the experience of the internal team. The best structure complements existing capability instead of duplicating it.
