Key Person Risk
Key person risk is the risk that a business cannot keep operating as expected when someone with essential knowledge or relationships leaves.

Why it matters to people buying a small business
A sale can transfer ownership without transferring the judgment that keeps work moving. If employees still need the departing seller to fix customer problems or approve unusual jobs, the buyer inherits that dependence.
An owner's role can hold knowledge of sales, marketing, and accounting that the job title doesn't reveal. The buyer needs to know which of those capabilities will still be there after the seller leaves.
The same goes for employees: a manager may hold the customer history or technical knowledge colleagues rely on. Our guide to key person risk in an acquisition works through these continuity questions.
How key person risk is assessed
Start with the work that would stop or stall if someone were unavailable. Ask who handles exceptions, where the supporting information lives, and whether anyone else has handled similar situations alone. These are questions to investigate, not inputs to a score.
For example, picture a service business where an estimator prepares routine quotes but the owner prices unfamiliar jobs. The buyer expects the estimator to take over quoting. Walking through a recent unusual request shows the estimator gathered the information and the owner made the call.
The handoff question is now about judgment, not paperwork. Naming a replacement doesn't mean the replacement can do the work. Separate what someone has shown they can do from what they are expected to learn.
Common mistakes
Assuming a capable new owner can absorb every responsibility hides the learning burden. Experience helps, but it doesn't bring customer history or knowledge of how the team solves problems.
Another mistake is taking the organization chart as proof of continuity. A management layer may never have run the business under pressure without the owner. Ask for examples of decisions the team has already made without the key person.
Routine approvals and knowledge nobody else holds are different problems. Name the missing capability before discussing fixes.

Owner dependence focuses on work and relationships tied to the seller. Management depth asks whether the remaining team has shown it can run the business.
