Customer concentration

How much of a company's revenue depends on a few customers or sales partners. The higher it is, the more losing one of them would hurt.

Simple example

One shop sells to 20 customers who each bring in about 5% of revenue. Another gets 60% of its revenue from just two customers. If the second shop loses one of them, 30% of its sales disappear overnight.

Spread out: 20 customers, about 5% eachConcentrated: 2 customers bring in 60%30%30%everyone else 40%Lose one big customer and 30% of revenue is gone.
