What Questions Should You Ask Before Buying a Business?
By Troy Frank, Owner — Indiana Equity Brokers

The short answer: Before buying a business, ask detailed questions in six areas: recent challenges, financial quality, legal and contract risk, operations and vendor concentration, the team, and market position. Roughly 30–50% of signed letters of intent fall apart during due diligence, usually because a buyer uncovers something the seller didn’t fully disclose. The right questions, asked early, protect you from overpaying and from inheriting problems you didn’t sign up for.
Most buyers start due diligence by asking for tax returns. That’s a start, but it’s not enough. The businesses that fall apart mid-deal usually don’t fail because a number was wrong — they fail because the buyer never asked the question that would have surfaced the real risk.
At Indiana Equity Brokers, we’ve sat on both sides of this process hundreds of times. The buyers who close successfully are the ones who dig past the pitch and into the details. Here are the questions that matter most, organized by the area of the business they cover.
1. What’s Actually Gone Wrong in the Last 12 Months?
Every seller will tell you their business is healthy. Ask them to be specific instead:
- What were the top 3–5 challenges over the past year?
- Where did cash flow miss the forecast, and why?
- Which customers or suppliers left, and what caused it?
- Where do operations bottleneck — staffing, compliance, capacity?
A seller who can answer these clearly, with specifics, is usually being straight with you. A seller who deflects into generalities is a signal to look closer.
2. Is the Financial Picture Real?
Financial due diligence is where most deals get re-traded or killed. Ask for:
- Reviewed or audited financials for the past 3–5 years
- A normalized income statement — one that strips out one-time or owner-specific expenses
- Revenue broken out by customer, product line, and channel
- Accounts receivable aging, inventory turnover, and bad debt history
- A full list of debt, lease obligations, and any off-balance-sheet liabilities
The goal is to separate reported profit from sustainable profit. A seller’s discretionary earnings (SDE) figure that looks strong on paper can shrink fast once you adjust for one-time equipment sales, related-party rent, or an owner’s personal expenses run through the business. This is exactly the kind of gap a buyer needs a broker or CPA to catch before it becomes a post-close surprise.
3. What Legal or Contract Risk Comes With the Business?
Contracts and legal exposure are the second most common deal-killer we see. Ask:
- Is there any pending, threatened, or past litigation, and what’s the exposure?
- What material contracts exist — vendors, customers, leases, licenses — and are they assignable to a new owner?
- Do any contracts include a change-of-control clause that triggers on sale?
- How is intellectual property owned or licensed?
- Are there open tax, environmental, or employment compliance issues?
A lease that isn’t assignable, or a customer contract that terminates automatically on a change of ownership, can quietly gut the value of what you’re buying. We covered this exact scenario in Can a Landlord Kill Your Business Sale? — it applies just as much to buyers as sellers.
4. How Dependent Is the Business on a Few Relationships?
Concentration risk is one of the fastest ways a healthy-looking business turns fragile. Ask:
- What share of revenue comes from the top 3–5 customers?
- Is the business reliant on one or two key vendors or suppliers?
- What’s the condition and remaining useful life of major equipment?
- Are there documented standard operating procedures, or does the business run on the owner’s memory?
If 30–40% of revenue sits with a single customer, that relationship is now your risk, not just the seller’s. Ask what happens to that account if the business changes hands — some buyers negotiate a holdback tied to key customer retention for exactly this reason.
5. Will the Team Stay After Closing?
A business is only worth what its people can deliver without the current owner in the room. Ask:
- Who are the key managers and employees, and do they know a sale is happening?
- What retention incentives or change-in-control arrangements exist?
- What’s turnover looked like over the past two years?
- How much of the day-to-day depends on the owner personally?
An owner-dependent business — one where the seller is the sales team, the operations manager, and the only person who knows the vendors — carries transition risk that a due diligence checklist alone won’t catch. This is worth a direct, uncomfortable conversation before you sign anything.
6. Does the Business Have Room to Grow?
Past performance tells you what the business has done. It doesn’t tell you what it can do under new ownership. Ask:
- What’s the realistic size of the addressable market?
- Who are the real competitors, and how defensible is the current position?
- What are the two or three levers most likely to grow revenue in year one?
- What’s customer churn and lifetime value look like?

Frequently Asked Questions
How long does due diligence take when buying a small business?
Most small business due diligence runs 30–90 days, with 45–60 days being typical for a Main Street or lower middle market deal. Complex businesses with real estate, multiple entities, or messy books can take longer.
Why do so many deals fall apart during due diligence?
An estimated 30–50% of signed letters of intent fail to reach closing during due diligence. Most fall apart when a buyer uncovers financial inconsistencies, contract issues, or customer concentration the seller hadn’t fully disclosed upfront — which is why asking the right questions early matters more than asking a lot of questions late.
Should I hire a professional for due diligence, or can I do it myself?
Bring in a CPA to review financials and a business attorney to review contracts and liabilities. A business broker can help you interpret what’s normal for the industry versus what’s a genuine red flag — that context is hard to get on your own, especially on a first acquisition.
What’s the single biggest red flag in due diligence?
Financials that don’t hold up to normalization — revenue or margins that look strong until you strip out one-time items, or a seller who can’t produce clean records for the past three years. Books that are hard to verify are usually hiding something, even if it isn’t intentional.
Ready to Start Looking at Deals?
Buying a business without a structured question list is how buyers overpay or inherit problems they didn’t see coming. The good news: due diligence gets easier with the right process and the right people asking the questions with you.
