Whether you are preparing to sell your business or seeking to add an investor to your cap table, first impressions matter. Buyers and investors look for the same things: stability, transparency, predictability and growth potential. Yet many deals are delayed, close at a significant discount or fall apart because of avoidable red flags. Here are five of the most common red flags buyers spot in due diligence, plus practical fixes to improve buyer confidence and valuation.

Nothing deters a buyer faster than unreliable numbers. Investors want to understand true profitability, cash flow and the working capital profile. If your accounts are incomplete, inconsistent or heavily “adjusted” at the last minute, they will assume the worst.

Fix: Get accounts up to date. Produce monthly management accounts that reconcile to statutory accounts, reconcile bank statements, and prepare 2–3 years of clean financials before discussions. Get help if needed; it will be worth it. Have a look at our Services.

Concentration can be efficient, but in a sale process it reads as risk. If more than 30% of revenue comes from one client—or one supplier is critical to production—buyers will ask: “What happens if they leave?”

Fix: Diversify revenue and your supplier base where feasible. If not realistic, strengthen contracts (term, pricing, service levels, change-of-control) to mitigate risk.

Founder disputes, unissued options or unclear IP ownership can stall a deal. Buyers want a clean cap table and no hidden liabilities. Historic baggage reduces certainty and price.

Fix: Review articles and shareholder agreements, update option schemes, ensure robust IP assignments (including consultants). Resolve disputes early and document everything.

If the owner is the business’s driving force, succession risk rises. Investors want to see a capable team that can continue without you.

Fix: Build a second line of management. Empower key staff, document core processes and reduce founder reliance.

Cash discipline signals operational health. High debtor days, poor stock management or reliance on overdrafts suggests fragility.

Fix: Tighten credit control, improve forecasting, optimise stock turns and renegotiate supplier terms. Demonstrate consistent cash discipline throughout diligence.

Preparation avoids surprises, and surprises kill acquisitions. Address these red flags early to protect value, shorten timelines and increase competitive tension. A business without obvious red flags is a business buyers compete to own.
