Our business is different and hence we do not need statistical forecasting & planning

All businesses are different and all companies run differently. Hence we cannot make generalizations in the business beyond an extent anyways.  Statistical forecasting helps in eliminating biases and perceptions. It helps is laying down a baseline sales forecast which gives a direction to the business to shape it further for desired outcome. It is hard to imagine if any business runs without estimations and planning. If you need to do it anyways then why not do it well and scientifically.
