How to Use Bank Statements to Verify a Seller’s Claims

The CIM shows you the story. The bank statements show you the truth. Here’s the 6-step framework for extracting intelligence from bank reconciliations.

Why Bank Statements Matter

The CIM is a narrative. Financial statements can be prepared with discretion. Tax returns show what the owner wanted the government to see. But bank statements? Bank statements show what actually happened. Every deposit. Every withdrawal. Every transfer. They can't be retroactively edited.

In our experience analyzing deals, bank statements are the single document most likely to reveal red flags that change the economics of an acquisition.

The 6-Step Bank Statement Analysis

Step 1: Deposit Verification

Total deposits should reconcile to reported revenue within 5%. Add up every deposit for each month. Compare to the monthly revenue the CIM or financials claim. A 10%+ gap means either revenue is overstated, or there are non-operating deposits (owner loans, related party transfers) being counted as revenue.

Step 2: Cash Flow Pattern Analysis

Plot the ending balance for each month over the full period. Look for:

  • Seasonal patterns: Does cash drop every summer? Every Q4? The CIM probably didn't mention this.
  • Negative balances: If the operating account went below zero at any point, the business has working capital problems regardless of what the balance sheet says on year-end.
  • Overdraft fees: These are a direct indicator of cash management stress.

Step 3: Transfer Tracing

Identify every transfer to/from accounts not on the CIM's financial statements. Common discoveries:

  • Transfers to a holding company (undisclosed owner distributions)
  • Transfers to personal accounts (personal expenses not add-backed)
  • Transfers from a line of credit (debt not on the balance sheet)
  • Transfers to/from related entities (intercompany obligations)

In one deal we analyzed, monthly transfers of $5,271 to a holding company added up to $63K in annual owner extraction that the CIM completely omitted. That's $63K that directly impacts SDE and the deal multiple.

Step 4: Debt Service Verification

Match every recurring payment to a known obligation on the debt schedule. Any payment that doesn't match a disclosed loan is an undisclosed obligation. Check:

  • Do the monthly payments match the debt schedule amounts?
  • Is there interest being paid on facilities listed as "0% interest"?
  • Are there lease payments not classified as debt?
  • Are there equipment finance payments that don't appear on the balance sheet?

Undisclosed debt directly impacts your DSCR calculation. Even $50K-$100K in additional obligations can flip a deal from bankable to unbankable.

Step 5: Expense Anomaly Detection

Look for payments that seem inconsistent with the business operations described in the CIM. Large one-time payments to unknown vendors. Recurring payments that don't match any expense category. Payments to law firms, accountants, or consultants at levels that suggest undisclosed issues (litigation, tax problems, restructuring).

Step 6: Year-End Timing Analysis

Compare the last month of the fiscal year to the rest of the year. Sellers know that year-end financials are what buyers see. They may accelerate receivables collection, delay vendor payments, or time large deposits to inflate the year-end snapshot. The bank statements reveal whether the year-end balance is representative or manufactured.

What JCoBee Does With Bank Statements

When you upload bank statements to JCoBee's DD document system, the platform auto-classifies them, extracts the key data, and cross-references every finding against the existing CIM analysis. The result is a structured DD findings report showing exactly where the CIM's claims match reality — and where they don't.

Each finding includes the specific claim from the CIM, the evidence from the bank statements, a severity rating, and the financial impact. The deal score adjusts automatically. The financials restate. The Gap Analysis shows you exactly what changed and by how much.

The broker can argue with your opinion. They can't argue with their own bank statements.

The Bottom Line

Request 24 months of bank statements as your first DD document request. Not the balance sheet. Not the tax returns. The bank statements. They're the single most powerful tool for verifying — or disproving — everything the CIM told you.
