Hindus believe that, if Pooja is done and God is invoked for the blessings, any place with negative energies and aura can be changed into a positive environment, fit for starting any new business. Before opening any new office or business, God must be worshiped to bless the place and remove all the negativity from there.
As Lord Ganesha is the God of all good things and is worshiped for his blessings, then all the negativity from the place are removed and it is blessed and fit to do business from, and he will bring good omen.
It will remove all the ill effects of Vastu and Navgraha. It will help the person acquire good health from the place and succeed in business, as the place is not positive and shubh for doing business.
