No one can exactly tell how long does moving offices take. But, you must have one thing in mind. The longer your office is closed, the more downtime it will cause your business. An optimal time for relocating an average office is up to 12 months. Yet everything depends on moving your office, documents, equipment, employees, and others. One thing is for sure. You need to start the planning process early. Organise a meeting and discuss the moving plan with employees.
