Avirtualassistant (typically abbreviated to VA), https://en.wikipedia.org/wiki/Virtual_assistant is generally self-employed and provides professional administrative, technical, or creative (social) assistance to clients remotely from a home office.
A VA is a not an employee, but a self-employed entrepreneur , so any costs related to employees, like taxes, medical aid, leave etc. are already calculated into their transparent and agreed upon fees.
You, as a client, will pay only for the work produced, eliminating specific employee costs, and ensuring maximum productivity in your business.
Virtual Assistants come from a variety of business backgrounds, but most have several years experience earned in the “real” (non-virtual) business world. Communication and data delivery include the internet, e-mail and phone-call conferences, online work spaces and social communication platforms such as Skype, Facebook or Whatsapp.
Professionals in this business work on a contractual basis and a long-lasting cooperation is standard.
