A single virtual assistant is often a great starting point, but it puts a ceiling on how much can realistically be delegated — one person only has so many hours and so much specialized skill.
A remote business support team, by contrast, is built around coordinated specialists: someone handling calendar and inbox management, someone else managing bookkeeping, another managing outreach — all working from a shared understanding of your business, usually organized by a project manager.
The right choice depends on scope. If your needs are narrow and consistent, a single VA can work well. If your needs span multiple functions, a coordinated team avoids the overhead of managing several disconnected freelancers yourself.
