A virtual office is a service that provides businesses with a professional address, phone number, and other office-related services without the need for physical office space. It allows employees to work remotely while maintaining a corporate presence. Services often include mail handling, call answering, and access to meeting rooms. Virtual offices are cost-effective, flexible, and ideal for startups, freelancers, or remote teams. They offer the benefits of a traditional office without the overhead costs or long-term commitments.
