If the expense is minimal compared to what it does for you in sales, it's worth the investment. If the expense puts you under, it isn't. Both have probably happened to Nexstar companies. It took me 20 years to change to flat-rate. My sales have increased well since the change. I made improvements in sales & marketing and sales have increased well. If I had known then what I know now, I would have earned at least $10,000 more per year. Who knows what else I'll learn by myself. I should be pretty good by the time I retire.
