Series Article #10 of 10
Welcome to the final article in our "Building a Transferable Business" series. Over the past nine articles, we've covered everything you need to know to build a sellable business. Now, let's talk about what can destroy it all—and how to avoid these costly mistakes.
📊 REALITY CHECK: According to exit planning advisors, 80% of businesses that go to market either don't sell or sell for significantly less than expected. The reason? Avoidable mistakes that destroy value.
The $2.4 Million Mistake
Mark owned a $12M revenue manufacturing company with strong EBITDA of $2.4M. After two years of preparation, he went to market expecting offers around $9.6M (4x multiple).
What happened instead:
Initial buyer interest was high—12 qualified buyers
After due diligence, 10 walked away
The remaining 2 offers came in at $4.8M and $5.5M
He lost $4 million in value
The culprit? Not one big mistake—but seven "small" issues that compounded:
Waiting too long to prepare (started only 6 months before selling)
Inconsistent financials (different numbers on tax returns vs. P&L statements)
Customer concentration (one customer = 38% of revenue)
Lack of documented systems (everything was in Mark's head)
No management team (Mark was the only decision-maker)
Legal issues discovered during due diligence (expired permits, unclear IP ownership)
Poor negotiation tactics (accepted the first offer without shopping it)
Each mistake cost him approximately $500K-$700K in lost value.
The 10 Most Expensive Mistakes (And How to Avoid Them)
❌ MISTAKE #1: Waiting Until You're "Ready to Sell" to Start Preparing
Cost: 20-40% reduction in sale price
Why it's deadly: Buyers can tell when a business has been hastily "dressed up" for sale. It reeks of desperation and raises red flags.
Real Example:
Business with $1.5M EBITDA
• Prepared 3 years in advance: Sold for 5.5x = $8.25M
• Prepared 6 months in advance: Sold for 3.2x = $4.8M
• Difference: $3.45M
✓ THE FIX:
Build transferability into your business from day one. Even if you're not planning to sell for 10 years, run your business as if you're selling in 3 years. This forces you to create systems, delegate, and build a management team—all of which make your business more valuable AND more enjoyable to run.
Timeline:
Minimum: 2 years of preparation
Recommended: 3-5 years
Ideal: Build transferability from day one and maintain it
❌ MISTAKE #2: Mixing Personal and Business Finances
Cost: 15-30% reduction in sale price + risk of deal collapse
Why it's deadly: Commingled finances create confusion, raise red flags about financial integrity, and make EBITDA calculations impossible. Sophisticated buyers will walk away. Less sophisticated buyers will lowball you to compensate for the risk.
What Buyers See:
• Personal expenses run through business = Potential fraud
• Business paying owner's personal bills = Unprofessional
• No clear separation = "What else are they hiding?"
• Mixed accounts = Impossible to verify true profitability
✓ THE FIX:
Complete financial separation—starting NOW:
Separate bank accounts: Business and personal, no crossover
Separate credit cards: Never use personal cards for business expenses
Pay yourself properly: W-2 salary or distribution—not random draws
Document add-backs: If you must run personal expenses through the business, document them clearly as owner perks that will be added back to EBITDA
Clean books: 3 years of clean, separated financials before going to market
❌ MISTAKE #3: "Cash Business" or Unreported Revenue
Cost: 100% of unreported revenue (you can't get credit for income you didn't report)
Why it's deadly: If you tell a buyer "I really make more than my tax returns show," you're confessing to tax fraud. No legitimate buyer will touch you. You'll attract only bottom-feeders who will use this against you in negotiations.
Real Example:
Restaurant owner: "My tax returns show $800K revenue, but I really make $1.2M."
Result:
• No legitimate buyers would engage
• Only offer: 1.5x on reported income = $1.2M
• Lost $600K in unreported income with ZERO credit
• Plus: Risk of IRS audit triggered by sale disclosure
✓ THE FIX:
Report all income—period.
Stop the practice NOW: Start reporting 100% of revenue immediately
Clean period needed: Minimum 3 years of accurate reporting before sale
IRS amnesty: Consider voluntary disclosure programs if past issues exist
Tax planning: Work with a CPA to minimize taxes legally through legitimate deductions, not unreported income
Remember: The tax you save by underreporting is NOTHING compared to the business value you destroy.
❌ MISTAKE #4: Failing to Diversify Your Customer Base
Cost: 25-50% reduction in sale price, or complete deal failure
Why it's deadly: Customer concentration is the #1 risk factor buyers evaluate. If one customer represents more than 15% of revenue, you don't have a business—you have a job that depends on one relationship.
Valuation Impact of Customer Concentration:
Business with $2M EBITDA:
• Top customer = 8% of revenue → Sold for 5.5x = $11M
• Top customer = 25% of revenue → Sold for 3.0x = $6M
• Top customer = 40% of revenue → No sale (deal collapsed)
Customer concentration cost this owner $5M+
✓ THE FIX:
The 15% Rule (revisited from Article #5):
Target: No single customer over 15% of revenue
Ideal: No single customer over 10% of revenue
Timeline: 2-3 years to safely diversify without disrupting operations
If you have concentration now:
Don't panic: Don't fire your big customer—grow around them
Aggressive new customer acquisition: Make this your #1 priority
Contract protection: Get multi-year contracts with your concentrated customers
Plan for the worst: If you can't diversify in time, structure the deal with earnouts based on customer retention
❌ MISTAKE #5: No Documented Systems or Processes
Cost: 30-50% reduction in sale price
Why it's deadly: "Tribal knowledge" businesses (where everything is in people's heads) are not transferable. Buyers see massive risk and will pay significantly less—or walk away entirely.
What Lack of Documentation Costs:
Service business, $1.8M EBITDA:
• With documented SOPs, training manuals, systems → 5.0x = $9M
• Without documentation (tribal knowledge) → 3.0x = $5.4M
Lack of systems cost this owner $3.6M
✓ THE FIX:
Document everything (Article #3 framework):
Start with critical processes: Customer acquisition, service delivery, quality control
90-Day Documentation Sprint: Document one process per week
Use screen recording: Loom or similar—watch someone do the task, record it, transcribe it
Create an Operations Manual: Central repository for all SOPs
Test the documentation: Have a new employee or temp worker follow the SOP—if they can do it, it's documented well
Minimum documentation needed:
Customer acquisition and sales process
Service delivery or production workflows
Quality control and customer service protocols
Financial management and reporting
HR processes (hiring, training, termination)
Technology systems and tools (logins, licenses, vendor relationships)
❌ MISTAKE #6: Being the Sole Decision-Maker
Cost: 40-60% reduction in sale price (or zero buyers)
Why it's deadly: If you're the only person who can make decisions, approve spending, manage employees, or handle customers—you don't have a business, you have a job. The business can't transfer without you.
Owner Dependency Value Destruction:
Construction company, $2M EBITDA:
• Owner in strategic role, GM runs operations → 5.0x = $10M
• Owner runs everything, no second-tier leadership → 2.5x = $5M
• Owner IS the business (no team at all) → 1.5x = $3M or no buyers
Owner dependency cost up to $7M in value
✓ THE FIX:
Build a management team (Article #6 framework):
Minimum: One strong #2 (GM, Operations Manager, or COO) who can run day-to-day operations
Recommended: 3-person leadership team covering operations, sales, and finance
Timeline: 2-3 years to recruit, train, and prove the team can run without you
Transition your role:
Year 1: Hire and train your #2, delegate operations
Year 2: Take a 2-week vacation—business runs without you
Year 3: Take a 4-6 week vacation—business thrives without you
Result: You've proven transferability; buyers will pay a premium
❌ MISTAKE #7: Legal and Regulatory Landmines
Cost: 20-100% reduction in sale price (deals collapse in due diligence)
Why it's deadly: Legal issues discovered during due diligence are deal-killers. Even "small" issues give buyers leverage to renegotiate down—or walk away entirely.
Common Legal Landmines:
• Expired licenses or permits → Deal delay or collapse
• Non-compete agreements with unclear terms → Renegotiation down 15-30%
• Intellectual property not properly owned by company → Deal collapse
• Employment law violations (misclassified contractors) → Renegotiation down 20-40%
• Lease issues (non-transferable or expiring soon) → Deal collapse
✓ THE FIX:
Conduct a legal audit 18 months before sale (Article #7 checklist):
Corporate structure: Proper formation, bylaws, shareholder agreements
Licenses and permits: All current, transferable, and in company name
Intellectual property: Trademarks, copyrights, patents properly owned by company
Contracts: Customer and vendor contracts assignable; no personal guarantees
Real estate: Lease transferable with 3-5 years remaining, or property owned free and clear
Employment law: Proper classification (employee vs. contractor), I-9s, background checks
Litigation: No pending lawsuits or regulatory actions
Fix issues NOW—not during due diligence.
❌ MISTAKE #8: Poor Negotiation and Deal Structure
Cost: 10-30% reduction in sale price + unfavorable terms
Why it's deadly: The first offer is rarely the best offer. Inexperienced sellers accept the first offer out of excitement or fear—leaving hundreds of thousands (or millions) on the table.
Real Example:
SaaS company, $1.2M EBITDA:
• First offer received: 4.5x = $5.4M (owner almost accepted immediately)
• After competitive bidding process: 7.2x = $8.64M
Accepting the first offer would have cost $3.24M
✓ THE FIX:
Create competition and negotiate strategically:
Never accept the first offer: Use it to create competition
Multiple buyers: Have at least 3-5 serious buyers competing
Hire professionals: Business broker, M&A advisor, or investment banker to manage the process
Understand deal structure: Cash vs. earnout, seller financing, employment agreements—all affect your true payout
Don't negotiate alone: Emotions cloud judgment; let advisors negotiate for you
Key negotiation principles:
Leverage: Competition creates leverage; never negotiate with one buyer
Information: Control what buyers know and when they know it
Terms matter: A $10M offer with unfavorable terms may net you less than a $9M all-cash offer
Walk-away power: Be prepared to walk away; desperation destroys value
❌ MISTAKE #9: Letting Employees, Customers, or Vendors Find Out Too Early
Cost: 20-100% reduction in sale price (business deteriorates during sale process)
Why it's deadly: When word gets out that the business is for sale, employees panic, customers get nervous, and vendors worry about payment. This triggers a downward spiral: key employees leave, customers stop renewing, vendors demand cash payment—and your business deteriorates right when you need it to look strongest.
Real Example:
Professional services firm:
• Word leaked that business was for sale
• 3 key employees left within 2 months
• 2 major customers switched to competitors
• EBITDA dropped 30% during the sale process
• Deal collapsed; had to start over a year later
✓ THE FIX:
Maintain strict confidentiality until the right time:
Tell NO ONE initially: Not employees, not customers, not vendors—no one except your spouse and advisors
Use NDAs: All potential buyers must sign before receiving any information
Control information flow: Blind profiles (no company name) until serious buyers are qualified
Time the announcement: Tell key employees and customers only after a deal is signed (or very close)
When to tell key stakeholders:
Key employees: After Letter of Intent (LOI) is signed, before due diligence
Customers: After deal closes (or during final week with retention agreements)
Vendors: After deal closes
Retention strategy:
Key employees: Retention bonuses paid at closing and 6-12 months post-closing
Communication plan: Carefully crafted messaging about continuity and opportunity
Buyer involvement: Have the buyer meet key employees and customers to build relationships
❌ MISTAKE #10: Selling at the Wrong Time
Cost: 30-50% reduction in sale price
Why it's deadly: Timing the sale of your business is like timing the sale of real estate—sell at the peak, not the decline. Buyers pay premiums for growth and momentum, not for problems and declining performance.
Valuation Impact of Timing:
Same business, $2M EBITDA:
• Sold during growth phase (revenue up 20% YoY) → 6.0x = $12M
• Sold during flat phase (revenue flat) → 4.0x = $8M
• Sold during decline (revenue down 10%) → 2.5x = $5M
Timing cost up to $7M in value
✓ THE FIX:
Sell at your peak—not when you're exhausted:
Best time to sell: When business is growing, profitable, and running smoothly without you
Worst time to sell: When revenue is declining, you're burned out, or a crisis has hit
Momentum matters: Buyers pay for future potential, not past performance
Ideal sale timing indicators:
✓ Revenue growing 10-20%+ annually for 2-3 years
✓ EBITDA margins stable or improving
✓ Strong pipeline of future business
✓ Recent wins (new customers, new products, expanded markets)
✓ Management team in place and performing well
✓ You've taken a 4-week vacation and business thrived
Don't wait for these (you've waited too long):
✗ Health crisis or family emergency
✗ Burnout or exhaustion
✗ Declining revenue or margins
✗ Loss of key customer or employee
✗ Industry disruption or increased competition
The Million-Dollar Mistake Matrix
Here's how these mistakes compound to destroy value:
Mistake | Typical Value Destruction | Time to Fix | Priority |
|---|---|---|---|
Waiting too long to prepare | 20-40% | 3-5 years | 🔴 CRITICAL |
Mixed personal/business finances | 15-30% | 3 years (clean track record) | 🔴 CRITICAL |
Unreported income ("cash business") | 100% of unreported $ | 3 years (clean track record) | 🔴 CRITICAL |
Customer concentration | 25-50% | 2-3 years | 🔴 CRITICAL |
No documented systems | 30-50% | 12-18 months | 🟠 HIGH |
Owner dependency | 40-60% | 2-3 years | 🔴 CRITICAL |
Legal/regulatory issues | 20-100% (deals collapse) | 12-24 months | 🟠 HIGH |
Poor negotiation | 10-30% | 3-6 months (hire advisors) | 🟡 MEDIUM |
Confidentiality breach | 20-100% (deal collapse) | Immediate (NDA protocols) | 🔴 CRITICAL |
Selling at wrong time | 30-50% | Varies (sell at peak) | 🟠 HIGH |
Note: These mistakes compound. A business with 3-4 major issues will see 60-80% value destruction compared to a well-prepared business.
