A virtual assistant (typically abbreviated to VA, also called a virtual office assistant) is generally self-employed and provides professional administrative, technical, or creative (social) assistance to clients remotely from a home office. Because virtual assistants are independent contractors rather than employees, clients are not responsible for any employee-related taxes, insurance, or benefits, except in the context that those indirect expenses are included in the VA’s fees. Clients also avoid the logistical problem of providing extra office space, equipment, or supplies. Clients pay for 100% productive work and can work with Virtual Assistants, individually, or in multi-VA firms to meet their exact needs. Virtual Assistants usually work for other small businesses. but can also support busy executives. It is estimated that there are as few as 5,000-10,000 or as many as 25,000 virtual assistants worldwide. The profession is growing in centralized economies with “fly-in, fly-out” staffing practices.
