Research consistently shows that many business owners fail to achieve the full or fair value of their business when exiting — not because the business lacks potential, but because of poor planning and preparation.
Selling a business requires strategy, structure, and forethought. Below are 12 common mistakes to avoid if you want to maximise value and complete a successful sale.
1) Deciding to Sell on Impulse
Selling a business should never be a snap decision.
Poor preparation — outdated accounts, incomplete legal records, unresolved disputes, or financial “skeletons in the cupboard” — will quickly surface during due diligence and can derail a deal.
Struggling businesses with unrealistic forecasts are especially difficult to sell. Buyers may simply wait for insolvency and acquire assets cheaply. Ideally, stabilise or improve performance before going to market.
Be realistic about timescales:
- Up to 6 months to find a buyer
- Up to 6 months to complete the transaction
Preparation is everything.
2) You Are the Business
Many owner-managed businesses are highly profitable because the owner controls everything tightly. While this protects margins, it creates risk for buyers.
If the business cannot operate without you, buyers will discount the price.
The higher the perceived risk, the lower the value.
To increase saleability:
- Delegate operational responsibilities
- Build a management layer
- Document processes
- Reduce reliance on your personal relationships
A business that runs without you is worth more than one that depends on you.
3) Over-Reliance on One or Two Customers
Customer concentration risk is a major red flag.
If one or two customers account for 20%+ of turnover, buyers may reduce their offer — or walk away entirely.
Ideally:
- Revenue is diversified across multiple customers
- Long-term or rolling contracts are in place
- Supplier relationships are stable and documented
Risk concentration reduces perceived value.
4) Being Unsure About Selling
Buyers will always ask: “Why are you selling?”
If your reason is vague or unconvincing, confidence drops.
Worse still, some owners withdraw midway through the process — wasting time, money, and professional fees.
Selling is a coordinated effort involving:
- Solicitors
- Accountants
- Brokers
- Buyers
You must be fully committed. Decide first. Then proceed.
5) Failing to Vet the Buyer
Not every interested party is a genuine buyer.
Some lack funding. Others are simply curious competitors.
Before agreeing terms:
- Request proof of funds
- Verify creditworthiness
- Ensure funding is realistically achievable
There is little point negotiating contracts if the buyer cannot complete.
6) Guessing What Your Business Is Worth
“It’s worth what someone will pay” is not a strategy.
A professional, independent valuation:
- Strengthens your negotiating position
- Clarifies whether selling is worthwhile
- Helps justify your asking price
Understand:
- Adjusted profits
- Maintainable EBITDA
- Asset values
- Tax implications
If income is not recorded, buyers will not pay for it.
7) Accepting a Free Broker Valuation at Face Value
Be cautious of “free valuations.”
Some brokers inflate values to:
- Win your instruction
- Justify high upfront fees
- Create unrealistic expectations
A credible valuation should show:
- Clear methodology
- Adjusted and maintainable EBITDA
- Market multiples
- Comparable transactions
If the detail isn’t there, the valuation isn’t robust.
8) Not Knowing Your Numbers
You don’t need to know every detail — but you must understand the fundamentals:
- Turnover
- Gross margin
- Net profit
- Balance sheet position
- Cash flow
- Forward projections
Buyers are particularly interested in future performance. A documented business plan significantly strengthens confidence.
Never guess figures. Inaccuracies damage trust immediately.
9) Failing to Identify Your USPs
Buyers care less about history and more about opportunity.
Focus on:
- Competitive advantages
- Barriers to entry
- Intellectual property
- Market position
- Growth potential
Frame weaknesses carefully — many can be positioned as future development opportunities for the buyer.
Value isn’t just in the accounts — it’s in the story.
10) Dealing With Only One Buyer
Competition drives value.
Aim to create interest from multiple buyers — ideally 4–6 serious parties.
Benefits:
- Competitive tension
- Higher offers
- Backup options if a deal collapses
If exclusivity is granted during due diligence, limit it (typically 90 days). This protects you from being locked into a renegotiation trap.
Always record unsolicited approaches — they may become valuable later.
11) Accepting the First Offer
The first offer is rarely the best offer.
Declining an initial proposal often results in a stronger return bid — especially if the buyer genuinely wants the business.
Best practice:
- Invite indicative offers
- Avoid publishing a firm asking price
- Never reveal your bottom-line number
But remain realistic — test your expectations by asking yourself what you would pay as a buyer.
12) Having No Marketing Material
Once interest is shown, a lack of structured information is a deal-killer.
After signing a Non-Disclosure Agreement (NDA), provide a professional Information Memorandum (IM) that includes:
- Business overview
- Market positioning
- Key financials
- Operational structure
- Growth opportunities
Ensure it is factual and accurate. Exaggeration will surface during due diligence and undermine trust.
The goal is to provide enough information to secure meaningful discussion — not to overwhelm or disclose sensitive data prematurely.
Final Thought
Selling a business should never be reactive — it should be strategic.
The most successful exits are planned years in advance.
Plan to sell your business.
As the saying goes: “if you fail to plan, you plan to fail”.
