Moron.Not necessarily. There are too many factors to make a blanket statement. If you already have extra customers what's the point of hiring more workers? Just because you already have more customers does not mean that will scale with the additional employees you hire. It might be better to bank the profit and build a second place for customers to buy from first. It might be better to invest in a parallel business. It might be better to hire better employees. It might be better to hire part time employees and see how it goes. Further, you have to look at regulatory issues. For example, as stated above when you go over magic numbers you might be susceptible to additional regulation. Still further it might be better for you to adjust your price upwards to reduce customers and shoot for higher margin on the sales.. this might reduce the number of customers... or maybe it won't. Even further, just because you have new customers today does not mean tomorrow they won't go to new competition that opens up across the street. You see when you are doing well.. everyone around you can see that, including your customers... some of which might be thinking about becoming your next competitor.
No there isn't. Either you do, or you don't.
