I have reviewed about 75 CIMs so far and one of the most common issues I came across is high customer concentration. My definition of high customer concentration is that either the top client provides more than 15% of the revenue or top 10 clients provide more than 50% of the revenue.

So, the question for the experts in the community is that whether there is any scenario based on industry or business type where it is okay to buy a business with a high customer concentration and I should do a little more digging than simply walk away?
