Top 30 Red Flags When Buying a Business

Buying a business is one of the biggest financial decisions you'll ever make. While due diligence helps uncover potential issues, some red flags are so serious that they should make you reconsider the entire deal. Here are the top 10 warning signs that experienced buyers never ignore.

## 1. Seller Won't Provide Tax Returns

**Why It's a Red Flag:** Tax returns are the most reliable financial documents because they're filed under penalty of perjury. A seller refusing to share them is hiding something.

**What to Do:** Walk away. No legitimate seller refuses tax returns to a serious buyer under an NDA. This is an immediate deal-breaker.

## 2. Declining Revenue Trend

**Why It's a Red Flag:** Revenue declining 10% or more year-over-year indicates fundamental business problems—lost customers, market changes, or competitive pressure.

**What to Look For:**
- 3-year revenue trend showing consistent decline
- Seller's explanation doesn't match market reality
- No credible turnaround plan

**What to Do:** Unless you have a specific plan to reverse the trend and the price reflects the risk, this is usually a pass.

## 3. Customer Concentration Over 25%

**Why It's a Red Flag:** If one customer represents more than 25% of revenue, you're buying a very risky business. If they leave, your business value drops immediately.

**Real Example:** A buyer purchased a manufacturing business where one customer was 40% of revenue. That customer left 6 months after closing, devastating the business value.

**What to Do:**
- Require customer commitment letters
- Negotiate a lower price reflecting the risk
- Have a diversification plan ready

## 4. Owner Working Less Than 20 Hours Per Week

**Why It's a Red Flag:** Sellers often claim "I barely work in the business" to make it seem easy. But if it's true and revenue is stable, why are they selling such a cash cow?

**The Reality:** Either:
- They're lying about involvement (you'll need to work 60+ hours)
- The business is about to decline (they see it coming)
- There are serious hidden issues

**What to Do:** Shadow the owner for a full week. Track actual time spent on the business including emails and calls.

## 5. Pending or Threatened Litigation

**Why It's a Red Flag:** Lawsuits are expensive and time-consuming, even if you win. They also indicate:
- Potential liability issues
- Unhappy customers or partners
- Legal/regulatory problems

**What to Do:**
- Get full disclosure of all litigation history
- Have your attorney review all cases
- Require seller to resolve issues before closing or escrow funds

## 6. Missing or Inconsistent Financial Records

**Why It's a Red Flag:** Professional businesses keep organized records. Missing documentation or inconsistencies between different financial statements suggest:
- Poor management (at best)
- Financial manipulation (at worst)

**Warning Signs:**
- QuickBooks doesn't match tax returns
- Bank statements don't reconcile with P&L
- Can't produce basic financial reports

**What to Do:** Hire a forensic accountant to investigate discrepancies. Don't close until you understand the true financial picture.

## 7. Key Employees Planning to Leave

**Why It's a Red Flag:** If critical employees won't stay after the transition, you're buying:
- A job, not a business
- No institutional knowledge
- Potential immediate operational chaos

**What to Do:**
- Interview key employees before closing
- Negotiate retention bonuses
- Get signed commitment letters
- If they won't stay, adjust price or walk away

## 8. Seller Rushing the Sale

**Why It's a Red Flag:** Legitimate sellers understand that proper due diligence takes time. Rushing suggests:
- Problems they want to hide
- Time-sensitive issues (lease expiring, contract ending)
- Not a serious seller

**What to Do:**
- Insist on proper due diligence timeline
- Ask directly: "Why the rush?"
- Their answer will be revealing

## 9. Price Significantly Below Market

**Why It's a Red Flag:** If a business is priced 30-50% below market multiples, there's always a reason:
- Seller knows about impending problems
- Hidden liabilities
- Unsustainable financials

**What to Do:** Dig deeper to understand why. A "too good to be true" deal usually is.

## 10. No Transition Support Offered

**Why It's a Red Flag:** A seller unwilling to help with transition doesn't believe in the business's future or wants to disappear quickly.

**What to Do:**
- Require 30-90 days of transition assistance in the purchase agreement
- If they refuse, question their motives
- Consider what they know that you don't

## The Bottom Line

Due diligence isn't just about checking boxes—it's about listening to what the business and seller are telling you. These red flags exist for a reason: they've cost buyers hundreds of thousands of dollars.

**Remember:** It's better to walk away from a bad deal than to buy someone else's problem. There will always be another business to buy.
