A virtual assistant (VA) is a real person working remotely, usually paid by the hour, who does your admin — inbox, diary, invoicing, documents, the paperwork side of running a business.
A virtual receptionist answers your phone live when it rings — greets callers in your business name, takes messages, books jobs. It can be a team of humans at an answering service, or an AI. (Giday, which we make, is the AI kind — and it tells every caller so, on every call.)
Same word "virtual", completely different jobs. One works through your backlog; the other catches the moment. If you remember nothing else from this page: admin problem, hire a VA; phone problem, get a receptionist.
