How to Evaluate a Small Business Before Buying It: 10 Financial Checks

Buying an existing small business can be an exciting opportunity. But before committing your savings or paying for extensive professional due diligence, you need to answer a fundamental question:

Is this business financially strong enough to deserve further investigation?

A profitable-looking business isn't always a healthy business. Revenue may be declining, expenses may be understated, or important liabilities may not be obvious in the seller's presentation.

These 10 financial checks can help you identify potential warning signs and decide what to investigate before moving forward.

1. Review at Least Three Years of Revenue

Start by examining the business's revenue history.

Ask the seller for annual profit-and-loss statements, ideally covering the last three years, together with more recent interim figures.

Look for:

• Consistent annual revenue growth or stability.

• Significant declines between years.

• Unusual sales increases that may not continue.

• Seasonal patterns or reliance on temporary contracts.

For example, a business that generated $600,000 in revenue three years ago but only $420,000 last year deserves closer investigation.

Key question: Is the business growing, stable, or declining—and why?

2. Examine Actual Profitability

Revenue alone tells you very little about what the buyer might earn.

Examine gross profit, operating expenses, and net earnings.

Pay particular attention to whether reported profit reflects the full cost of operating the business.

A company may report attractive profits because the current owner performs substantial unpaid work or receives below-market compensation.

Key question: How much profit would remain after paying the actual costs of operating the business under new ownership?

3. Check Cash Flow, Not Just Accounting Profit

A business can report a profit while struggling to pay its bills.

Review cash flow and available bank statements to understand whether operating activities generate sufficient cash.

Investigate:

• Customer payments that arrive late.

• Inventory purchases that consume cash.

• Large unpaid expenses.

• Significant equipment replacement needs.

• Differences between accounting earnings and actual cash movement.

Key question: Does the business generate dependable cash, or does it constantly require additional funding?

4. Verify Revenue Against Supporting Records

Do not rely exclusively on financial statements prepared by the seller.

Where available, compare reported sales with supporting evidence such as bank deposits, point-of-sale reports, invoices, sales tax filings, and tax returns.

Differences may have legitimate explanations, including cash timing, taxes, refunds, and accounting methods. However, substantial unexplained differences should be investigated.

Key question: Can the seller support the reported revenue with credible documentation?

5. Identify Unusual Expenses and Owner Adjustments

Business listings often advertise adjusted earnings or Seller's Discretionary Earnings (SDE).

These calculations may add back certain owner-related or non-recurring expenses.

Some adjustments are reasonable. Others may exaggerate the earnings a buyer can realistically expect.

For every proposed adjustment, request evidence and consider whether the expense will genuinely disappear after the purchase.

Key question: Are the advertised earnings supported by reasonable, documented adjustments?

6. Examine Debt and Other Liabilities

A business may look profitable while carrying serious financial obligations.

Review its balance sheet and ask about:

• Outstanding loans and lines of credit.

• Unpaid taxes or payroll obligations.

• Supplier balances.

• Equipment leases.

• Customer deposits and unfulfilled commitments.

• Potential legal or contractual liabilities.

Whether particular liabilities transfer to the buyer depends on the acquisition structure and contractual terms.

Key question: What financial obligations could reduce the business's value or affect the purchase?

7. Evaluate Customer Concentration

A business heavily dependent on a small number of customers may be more vulnerable than its financial statements initially suggest.

For example, suppose one customer generates 45% of annual revenue. Losing that relationship could dramatically affect profitability.

Review customer concentration, recurring revenue, contract duration, and the likelihood that important relationships will survive a change of ownership.

Key question: Would the business remain financially viable if it lost its largest customer?

8. Review Payroll and Owner Dependence

Employees and the current owner may be essential to keeping the business operating.

Consider the cost of replacing the owner's responsibilities, retaining key employees, and maintaining normal service levels.

A business that depends heavily on the seller's personal relationships, expertise, or unpaid labour may require substantial additional expense after acquisition.

Key question: Can the business operate successfully without the seller, and at what cost?

9. Assess the Asking Price Against Sustainable Earnings

An asking price should be evaluated in relation to financial performance, business risks, required investment, and relevant market comparisons.

One preliminary measure is the ratio of asking price to appropriately normalized annual earnings.

For example:

• Asking price: $450,000

• Supported normalized annual earnings: $90,000

• Implied asking-price multiple: 5 times annual earnings

That multiple is a starting point for analysis—not proof that the asking price is fair or unreasonable.

The appropriate valuation depends on factors such as industry, assets, growth prospects, transferable earnings, deal structure, and risk.

Key question: What evidence supports the seller's asking price?

10. Identify Missing Documents and Unresolved Questions

Sometimes the biggest warning sign is not a negative financial number. It is the absence of reliable evidence.

Watch for:

• Missing financial statements.

• Inconsistent information between documents.

• Unexplained revenue or expense changes.

• Unsupported earnings adjustments.

• Refusal to clarify important liabilities.

• Financial records that don't cover recent periods.

Missing information does not automatically mean the business is a bad investment. It means the level of uncertainty is higher.

Key question: Do you have enough credible information to justify proceeding to the next stage?

What Should You Do After These 10 Checks?

After reviewing the available evidence, your preliminary conclusion may fall into one of three categories.

GO: The available evidence supports continuing to more detailed professional due diligence.

CAUTION: The opportunity may be worth considering, but important risks, missing evidence, or pricing concerns must be addressed.

NO-GO: The available evidence indicates problems serious enough that proceeding may not be justified under the current circumstances.
