Key Insight
The business that runs perfectly while the owner is there — and quietly falls apart when they leave — is the most common acquisition trap in the SMB market. It doesn't show up in the financials until it's your problem.
Why Dependency Is the Primary Acquisition Risk
SDE measures what the business earns today, with the current owner running it. It doesn't measure what it will earn under new ownership. When the current owner is the reason customers stay, the reason contracts get renewed, or the reason the team functions — SDE overstates the transferable earnings power of the business.
This isn't rare. In businesses under $3M in revenue, high owner dependency is the rule, not the exception. The question isn't whether dependency exists — it's how severe it is and whether it can be managed.
Forms of Owner Dependency
Relationship dependency: The owner is the primary sales contact and relationship holder for key clients. Customers will follow the owner, not the business.
Technical dependency: The owner holds certifications, licenses, or specialized knowledge that the business cannot operate without (a PE license, a security clearance, a master electrician certification that enables the firm to pull permits).
Reputation dependency: The business trades on the owner's personal reputation — a consulting firm, a financial advisory, a law practice.
Operational dependency: The owner makes all the decisions, handles all escalations, and no one else knows how things work. Day one without the owner is day one of chaos.
Identifying Dependency During Due Diligence
- Customer interviews: Ask customers who they call when there's a problem. If the answer is always the owner by name, that's a signal.
- Employee interviews: Ask the management team what happens when the owner is out for two weeks. Honest answers reveal operational depth — or the lack of it.
- Revenue by relationship: Map each major revenue source to who owns the relationship. An account that has never met anyone but the owner is a dependency exposure.
- Contracts vs. relationships: Are customer contracts with the business entity or with the owner personally? Personal contracts don't transfer.
A residential HVAC company does $1.2M in revenue. The owner does all customer callbacks personally, handles all service complaints, and has been in the neighborhood for 25 years. Customers call asking for him by first name. Post-close, the new owner gets neutral reviews instead of five-star ones, three of the top-10 accounts leave within six months, and the business runs at 70% of prior revenue. The SDE was real. The transferability wasn't.
Pricing for Dependency
High owner dependency should either:
- Reduce the multiple — price in the transition risk explicitly
- Require a longer transition — 12-24 months of seller involvement, documented in the purchase agreement
- Trigger an earnout — make part of the price contingent on revenue retention through the transition
A seller who resists all three of these for a high-dependency business is pricing the business as if the dependency doesn't exist — which is the buyer's problem, not the seller's.
