A virtual office provides address (and sometimes communication) services for a fee, without providing dedicated office space. 

The virtual office idea came from a combination of technological innovation and the Information Age. Virtual offices are experiencing growth in every economy. This service help reduce overhead while keeping professionalism high. The portability of today's technology also allows for a more flexible work environment. As businesses trend to a more "online" workplace, the notion of paying for space full-time becomes anachronistic. Virtual office clientele has the flexibility to match expenses with revenue fluctuations immediately, as the costs are usually variable. A virtual office can allow for low-cost expansion with no long-term commitments.
