Customer and Sales Due Diligence

Customer Concentration

When a large part of revenue comes from a small number of customers. Buyers worry because losing one customer could hurt the business badly. Why it matters: This gives owners a clearer way to understand buyer questions, advisor comments, and negotiation tradeoffs during a sale process.

Also used in Common Red Flags Buyers Look For: Too much revenue from too few customers. Why it matters: Buyers may use this issue to ask for more diligence, reduce price, add protections, delay closing, or walk away.

Revenue

The total money the business brings in before expenses. Why it matters: Buyers look at revenue trends, customer mix, and repeatability to understand whether the business is growing, shrinking, or dependent on a few sources.

Buyer

The person, company, investor, or fund trying to buy the business. Why it matters: Different buyers value different things, so knowing the buyer type helps an owner understand likely questions, risks, financing needs, and negotiation style.
