Yeah, that is how we manage now. We have a base model with the essential features. But the clients request customizations to adapt it to their systems. Ironically, purchasing an off the shelf product from the market leader and customizing it would have cost lesser than developing our own entire system. Also the off the shelf systems available in market are having about 3x performance. We still manufacture the same because one of the Co-Founder believes that everything must be built in house and wants the company to be a production company. While I believe the company must be innovative.
