What buyers actually test in the first 90 minutes of diligence

Long before a valuation is debated, a buyer is checking whether the numbers can be trusted and whether the business runs without the owner. Those first questions decide whether the conversation moves forward, stalls, or turns into a lower offer. The good news is that every one of them can be answered months before you ever go to market.

If you are thinking about selling, it helps to know how due diligence when selling a business actually starts. Before anyone argues about price, the buyer’s first questions are predictable, and every one of them can be prepared for in advance.

1. Do the numbers tie out?

The first thing a serious buyer does is compare your tax returns, your profit and loss statements and your bank deposits. If revenue on the returns doesn’t match the P&L, or deposits don’t support either one, trust drops fast. From that point on, every number you share gets discounted.

• Three years of clean statements that match the tax returns.
• Documented add-backs. Personal expenses and one-time costs run through the business are normal, but each one needs a paper trail.
• Separate accounts. Business and personal money should not mix.

2. Will the revenue stay after you leave?

Buyers pay for future earnings, not past ones. They look at how concentrated your customers are, whether relationships are tied to contracts or to you personally, and how much revenue repeats on its own.

• If one customer is a large slice of sales, expect hard questions and a lower multiple.
• Written agreements, service contracts and recurring billing all make revenue easier to believe.
• Customer relationships held by a team are worth more than ones held only by the owner.

3. Does the business run without the owner?

Owner dependence is one of the biggest drags on value. A buyer will ask who quotes the jobs, who the key customers call, who approves spending and who knows how things actually get done. If the honest answer to most of those is “me,” the buyer is really buying a job, and they will price it that way.

Written processes, a capable second-in-command and decisions that happen without you are what turn a job into a transferable business.

4. Can a lender get comfortable?

Many small and mid-sized business purchases are financed, often with SBA-backed loans. That means a lender is quietly sitting on the buyer’s side of the table. Lenders want consistent earnings, reliable financial statements and a business that won’t collapse when the owner steps away. A business that can’t pass a lender’s review has fewer qualified buyers, and fewer buyers usually means a lower price.

5. What surprises are hiding?

Early on, buyers also scan for the things that blow up deals later:

• Leases that expire soon or can’t be assigned to a new owner.
• Licenses, permits or certifications held in the owner’s name.
• Open lawsuits, tax issues or compliance problems.
• Deferred maintenance on equipment, vehicles or facilities.

What this means for you

None of these questions are surprises. They show up in nearly every deal, which means they can be answered on your schedule instead of the buyer’s. Owners who prepare these answers in advance negotiate from strength. Owners who don’t often spend diligence explaining, apologizing and giving back value.

Frequently asked questions

How long does due diligence take when selling a small business?

It commonly runs anywhere from a few weeks to a few months, depending on the size of the business and how organized the records are. Owners who have documents ready usually move through it faster.

What documents do buyers ask for first?

Typically three years of tax returns and financial statements, bank statements, a list of add-backs, customer and vendor information, leases, licenses and key contracts.

What kills a deal in due diligence?

Numbers that don’t reconcile, heavy dependence on the owner, customer concentration and surprises such as unassignable leases or unresolved legal issues are among the most common deal breakers.
