Proof of cash reconciliation: how it works in a lender-side QoE
Short answer
A proof of cash rebuilds a business's cash receipts and disbursements from its bank statements and reconciles them to the revenue and expenses on the income statement and tax return, period by period. Differences reveal revenue that wasn't deposited, deposits that weren't revenue, and expenses paid outside the books. SBA's SOP 50 10 8.1 requires a cash proof in every required Quality of Earnings, covering the trailing 12 months and the last two fiscal years.
SBA's definition: a financial analysis that reconstructs cash receipts and disbursements by reconciling bank statement data to the income statement and tax return for each period under review, designed to identify discrepancies in income and undisclosed expenses. Here's how that works in practice.
The structure
Worked example
Illustration, not a real deal
Say a restaurant group reports $3,200,000 of revenue for the last fiscal year. Bank deposits across three accounts total $3,710,000.
| Receipts reconciliation | Amount |
|---|---|
| Total deposits, all accounts | $3,710,000 |
| Less transfers between the group's own accounts | −$420,000 |
| Less equipment loan proceeds | −$60,000 |
| Less sales tax collected (remitted separately) | −$240,000 |
| Add merchant processing fees netted from deposits | +$95,000 |
| Add increase in catering receivables | +$30,000 |
| Revenue supported by cash | $3,115,000 |
| Reported revenue | $3,200,000 |
| Unexplained difference | $85,000 (reported revenue higher than cash supports) |
An $85,000 shortfall needs an explanation: cash sales spent before deposit, gift card accounting, a third-party delivery platform paying into an account not provided, or overstated revenue. If it can't be explained, the QoE reduces revenue (and EBITDA) by that amount. Under SBA rules, the lender then uses the lower earnings for DSC.
What commonly shows up
- Undisclosed bank accounts (deposits that don't tie anywhere).
- Personal expenses paid from business accounts (support for add-backs, or a red flag if large and undocumented).
- Cash revenue kept out of deposits (can't be credited to earnings).
- Revenue recognized but never collected.
- Payroll paid through a separate entity.
Making it go faster
- Provide every bank statement for every account for all three periods up front.
- Include merchant processor and delivery platform statements.
- List all accounts and their purpose.
- Have the bookkeeper available for questions.

Reading a cash proof as a credit officer
A cash proof is only useful if someone reads the variances, not just the conclusion. When a lender-side QoE lands, these are the lines worth stopping on.
| Line | What a healthy result looks like | What to ask if it doesn't |
|---|---|---|
| Deposits vs reported revenue | Small, explained differences (timing, sales tax, transfers) | Is revenue going somewhere other than these accounts? Are there accounts missing? |
| Non-revenue deposits | Identified: owner contributions, loan proceeds, transfers, refunds | Were any of these counted as revenue in the internal statements? |
| Disbursements vs reported expenses | Close, after capex, loan principal and distributions | Are expenses being paid personally or from another entity? |
| Tax return vs books | Ties, or differences explained by tax adjustments | Which number did the valuer use? |
| Trend across periods | Variances consistent year to year | Why did the unexplained variance grow in the latest period? |
A clean cash proof doesn't prove earnings are sustainable; that's the revenue quality section's job. But an unexplained gap between deposits and revenue is one of the few findings that can stop a deal on its own, because it means the lender can't be sure what the business actually earns.
Why SBA requires all three periods
One year can look clean by accident or by design. Reconciling the trailing 12 months and the last two fiscal years shows whether revenue patterns are stable, whether a seller tidied up the books ahead of a sale, and whether the tax returns, which the lender verifies against IRS transcripts, describe the same business the bank statements do. If the business has operated for less than two years, the SOP lets the scope shrink accordingly.

Tying it to IRS transcripts
On an SBA change of ownership, the lender must verify the seller's financial data, including a selling sole proprietor's Schedule C, against IRS tax transcripts, and also verify the data the appraiser relied on. Transcripts come through IRS's IVES program or Form 8821 naming the lender (and any LSP) as designee. Discrepancies must be reconciled before first disbursement; a delegated lender that disburses without reconciling risks guaranty repair or denial.
Appendix 15 treats tax transcripts as an extension of the financial due diligence on a change of ownership. Here's the workflow and where it goes wrong.
Workflow
- Request transcripts for the seller's business (and applicant) via IVES or Form 8821; lender (and LSP) as designee; not filed by the borrower or its preparer.
- Request the right type: transcripts that reflect changes to the original return.
- Reconcile revenue, COGS, officer comp and net income to the financial statements and the appraiser's inputs.
- Explain differences in writing (accrual vs cash, timing, amended returns).
- Escalate: second request after 10 business days; "record not found" stops disbursement except under the narrow missing-middle-year rule.
Common mismatches
- Revenue in internal books higher than the return: unreported income can't support debt.
- Owner perks deducted on the return and added back by the broker: fine if documented, but each needs evidence.
- Entity changes (S to C, new EIN) breaking the year-over-year series.
- Sole proprietor selling: Schedule C is what's verified.
A small worked variance analysis
Illustration, not a real deal. Fiscal year 2: bank deposits $3,180,000; reported revenue $3,050,000.
| Bank deposits, all accounts | $3,180,000 |
| Less: transfers between the company's own accounts | -$95,000 |
| Less: line of credit draws | -$50,000 |
| Less: sales tax collected | -$41,000 |
| Plus: increase in receivables over the year | +$38,000 |
| Implied revenue | $3,032,000 |
| Reported revenue | $3,050,000 |
| Unexplained difference | $18,000 (0.6% of revenue) |
Check: $3,180,000 - $95,000 - $50,000 - $41,000 + $38,000 = $3,032,000. The provider would now ask the seller about the $18,000, for example card settlements netted of fees, before concluding. A difference of this size is usually explainable; one of 10% is a finding.
What sellers can do to make it painless
Sellers who want a quick, clean cash proof should send every bank, card and merchant processor statement for the whole period at once, explain all transfers between accounts, flag any owner deposits or loans, and make sure the bookkeeper can answer questions about large or unusual items. Running revenue through a single operating account, and keeping personal spending out of business accounts, makes the reconciliation faster and the result more convincing.
Where the proof of cash fits in the wider QoE
The cash proof is one of several reconciliations in a lender-side QoE. It sits alongside the reconciliation of accountant-prepared statements to tax returns and internal statements, the comparison of tax return figures to IRS transcript data, and the documentation of every add-back. Together they answer the lender's first question, whether the reported numbers are real, before the QoE moves on to the second, whether those earnings will continue after the sale.
Lenders reading the result should ask one question above all: is there any revenue the business claims that the bank statements do not show arriving? If the answer is no, the rest of the QoE can build on solid ground.
Common questions
What's a four-way proof of cash?
A classic audit format that reconciles beginning balance, receipts, disbursements and ending balance between the bank and the books for a period. QoE cash proofs use the same idea, extended to tie receipts to revenue and disbursements to expenses.
What documents does it need?
All bank statements for every account for the periods, the general ledger, financial statements, tax returns, merchant processor and payroll reports, and loan statements.
Does a proof of cash detect fraud?
It isn't a fraud examination, but it's very good at surfacing unexplained differences that someone then has to explain.
Is a proof of cash the same as a bank reconciliation?
No. A bank reconciliation matches the ledger's cash balance to the bank statement at a point in time. A proof of cash reconciles the flows (all receipts and disbursements for a period) to revenue and expenses on the income statement and tax return.
What if the business being sold is a division?
If transcripts or financial statements don't identify the division, the lender must use alternative third-party verification such as CPA-prepared or reviewed statements, sales tax records, transient occupancy tax records or credit reporting services.
