I didn't read this entire thread, so I'm probably not adding anything new, but...Guys in this business think that having a large number of mowing accounts will make them rich...so they cut prices to try to sign as many customers as possible. It is amazing to me how many people do this over and over, waiting for "economies of scale" to magically produce profits.
When I learned a little about business, I learned the difference between fixed costs and variable costs. Maintenance/mowing has small fixed, but huge variable. So there is almost no "economies of scale".
Buying customers with low prices is a recipe for losing money.
