What decision this helps you make: How to price and set terms with a big customer, and how hard to work at reducing your dependence on them.

What this topic is

Customer concentration risk is the danger of depending on one or a few customers: not just that they might leave, but that while they stay, their power over you compresses your prices, stretches your payment terms, and shrinks your margins.

Why it matters

A dominant customer holds real leverage: you can't afford to lose them, so you accept discounts, delays, and demands you'd refuse from anyone else. That power quietly erodes profit long before it ever threatens survival.

Who should learn it

Anyone with a few large clients (B2B suppliers, agencies, contractors, wholesalers), and anyone tempted to build their business around one big, demanding account.

What you will understand

  • See how a big customer's power erodes your margins
  • Recognize the concessions dependence forces you to make
  • Measure your exposure to a single dominant account
  • Win back bargaining power by reducing dependence

Prerequisites

Common misconception

"A big loyal customer is nothing but a blessing." A customer who knows they're a huge share of your revenue holds power over you, and research shows they use it, squeezing prices and terms in ways that quietly erode your margins.
