Questions to ask when buying a business
The questions every buyer should ask a seller before committing, across the numbers, the customers, the staff, and the real reason for selling.
Overview
The questions you ask a seller do two jobs: they tell you whether the business is sound, and they tell you whether the seller is being straight with you. A good owner welcomes sharp questions because they have nothing to hide and they want a buyer who understands what they are taking on.
This guide groups the questions worth asking by theme, so you can work through them in conversation and in writing. You will not get every answer at the first meeting, and you should not expect to; the point is to keep asking until the picture is complete and consistent.
Why are you selling?
Start here, and listen carefully. Retirement, ill health, relocation, or moving to a new venture are normal and reassuring reasons. Vaguer answers, or a story that shifts, deserve more probing. You are trying to understand whether the owner is leaving despite a healthy business or because of a problem you have not seen yet. Ask what they would do differently if they were staying.
Questions about the money
The numbers are where polite answers meet hard evidence:
- Can I see three years of accounts and recent management figures?
- What exactly makes up the "adjusted" profit, and which addbacks are one-off?
- How seasonal or lumpy is the revenue across the year?
- How quickly do customers pay, and is there any bad debt?
- Is there any debt, finance, or director loan attached to the business?
- What capital spending is coming up that I would inherit?
Questions about customers and revenue
Where the money comes from matters as much as how much there is:
- How much of the revenue sits with your biggest few customers?
- Is the revenue recurring or contracted, or won fresh each time?
- How are customers won, and how much of that depends on you personally?
- Have you lost any significant customers recently, and why?
Questions about people and operations
The things that walk out of the door with the owner:
- Which staff are key, and do they intend to stay after a sale?
- What do you personally do day to day that someone will need to replace?
- Are the important processes written down, or held in people's heads?
- What is the state and age of the equipment, premises, and systems?
Questions about the future and the handover
You are buying tomorrow, not just yesterday:
- What are the main risks and threats to the business over the next few years?
- What would you focus on if you were staying for another five years?
- How long will you stay on to hand over, and what does that involve?
- Are there any disputes, claims, or regulatory matters I should know about?
Watch how questions are answered, not just what is said
Pay attention to whether answers are specific and backed by documents, or vague and verbal. A seller who reaches for the figures, admits the weaknesses, and explains the context is showing you a business worth trusting. Evasiveness, irritation at reasonable questions, or numbers that change between conversations are signals to slow down and verify everything before you go further.

Frequently asked questions
- What is the single most important question to ask?
- Why are you selling? The honest answer shapes everything else. A genuine reason (retirement, health, a new venture) is reassuring; a vague or shifting answer is a prompt to dig deeper into whether there is a problem you have not yet found. It also tells you how motivated and flexible the seller is likely to be.
- When should I ask the detailed financial questions?
- Ask high-level questions early, but expect full financial answers only after you have signed the NDA and shown you are a serious buyer. Sellers reasonably hold back sensitive numbers until they know who they are dealing with. The deepest verification (accountant access to the books) usually comes during due diligence, after heads of terms are agreed.
- How do I ask tough questions without offending the seller?
- Frame them as a serious buyer doing proper homework, not as an accusation. Most owners respect a buyer who asks sharp, specific questions because it signals you can actually complete and run the business. If a seller is offended by reasonable diligence questions, that itself is useful information about how the rest of the process will go.
- What answers should make me walk away?
- Refusal to share basic financials, numbers that do not reconcile across accounts and bank statements, a reason for selling that keeps changing, undisclosed disputes that surface late, or persistent pressure to complete quickly without checks. None is automatically fatal, but a cluster of them, or any one that cannot be satisfactorily explained, is a reason to step back.
