The image of a company is very important. Would you want to work with a consultation company whose office was in shambles? We judge things often by their appearance, especially when seeing something for the first time. If you are an excellent company with a bad image or appearance then you may have loyal clients but new clients will be hard to get.
What does work, however, is the ability to present the company as being professional and experienced. When we walk into an office that is neatly arranged and greatly designed we immediately begin to think positively about the company.
