Best use
One-off tasks, research, design, admin cleanup, or narrow support projects.
Recurring customer-facing work where coverage, QA, continuity, and escalation matter.
Coverage
Depends on one person or a loose bench.
Built around shifts, backups, supervisors, and handoff rules.
Training
Usually self-managed by the buyer.
Turned into scripts, workflows, QA notes, and manager coaching.
Quality control
Varies by contractor and buyer review effort.
Uses scorecards, samples, exception review, and documented improvement.
Risk
Low commitment but high single-person dependency.
More setup, but stronger continuity and clearer accountability.
