Short answer: Verify seller financials by reconciling reported revenue and profit across tax returns, monthly statements, the general ledger, bank deposits, merchant processors, invoices, payroll, and operational records. Then rebuild normalized earnings and document every variance instead of assuming one source is correct.

Define the Periods and Entities

Confirm which entity and locations produced the revenue, which accounting basis is used, the fiscal year, and whether the listing uses a calendar year, trailing twelve months, annualized year-to-date period, or projection. Keep results for different periods separate.

Build the Revenue Bridge

Reconcile gross receipts on tax returns to financial statements, ledger sales accounts, bank deposits, merchant settlements, sales-tax filings, invoices, and operating systems. Account for timing, transfers, loans, taxes collected, refunds, chargebacks, cash sales, and multiple processors.

Investigate differences by transaction or month. A variance can be explainable without being immaterial. Preserve the reconciliation and source documents.

Test Expenses and Liabilities

Trace payroll, rent, insurance, utilities, marketing, supplies, repairs, professional fees, debt, taxes, and owner transactions. Review accounts payable, accrued payroll, customer deposits, gift cards, deferred revenue, and unpaid obligations that may not be obvious from a cash-basis P&L.

Verify Every Add-Back

Start with reported profit, then identify owner compensation, interest, depreciation, amortization, personal expenses, and claimed one-time costs. Require ledger detail and supporting documents. Restore recurring costs, market replacement labor, normalized rent, deferred maintenance, and buyer-specific expenses.

Measure the valuation effect. A disputed $20,000 add-back changes indicated value by $60,000 at a 3.0× multiple.

Analyze Quality and Trend

Compare monthly revenue, gross margin, payroll, and normalized earnings across years. Separate price, volume, mix, acquisitions, grants, one-time projects, and lost customers. Review receivable aging, inventory turns, chargebacks, and forecast accuracy.

Model Cash After Closing

Deduct debt service, buyer or manager compensation, taxes, maintenance capex, and normal working capital. Stress revenue, margin, payroll, interest, and customer loss. The result should explain both lender coverage and the buyer’s expected return.

Frequently Asked Questions

Are tax returns enough to verify a business?

No. They are important but should be reconciled with statements, ledger activity, bank or merchant evidence, payroll, invoices, and operating records.

How many years should a buyer review?

Three completed years plus current year-to-date and trailing performance is common, but scope should match volatility, seasonality, record quality, and lender requirements.

What if financial records disagree?

Document the variance, determine timing and classification differences, request transaction-level support, and avoid relying on the affected claim until the difference is resolved.
