I Got Business With Registered Office
This has much to do with the way you project your business. Having a prestigious office location printed on your organisation's letterhead is important for your business to score high on visibility. People actually sit up and take notice if you have a registered office at a popular commercial location. This scores some strategic points for your business. For instance, the next time, people see your company, they can associate it with the famous address of its registered office.
Mail forwarding service is also provided by the ones who provide a registered office address at a small charge. So official correspondence problem also: solved.
