A financial due-diligence checklist for a US small-business raise is, in practice, the finance data room: an indexed set of monthly financial statements, reconciliations that tie the books to bank and tax records, written metric definitions, compliance evidence, and a log of known issues. This guide is for US owners preparing for equity investors or lenders. The biggest limitation comes first: diligence verifies what you already record, so books that are months behind must be caught up before any checklist helps — and no checklist guarantees funding, credit approval, or investment.
Quick answer
Whether the counterparty is a private investor or a lender, the finance side of diligence rests on four things:
- Monthly reporting history — closed, reconciled months of income statement, balance sheet, and cash flow statement, plus year-to-date and trailing-twelve-month views.
- Tie-outs — every balance on the statements traces to an external record: bank statements, filed tax returns, receivable and payable ledgers, payroll filings.
- Metric definitions — each headline metric (revenue, gross margin, earnings before interest, taxes, depreciation, and amortization (EBITDA), burn, runway) is defined in writing and computable from the statements an investor is reading.
- An issue log — known problems disclosed with an owner and a remediation plan, before the reviewer finds them unlisted.
The sections below deliver each piece: a data-room index, a tie-out checklist with a worked revenue reconciliation, history and recordkeeping requirements, a metric-definition table, an issue-log format, and a 90-day owner timeline.

Who reviews diligence, and under which rules?
Equity investors operate in a federal securities framework. The U.S. Securities and Exchange Commission (SEC) maintains a small-business portal whose stated purpose is to:
“Explore SEC resources to help equip small businesses, from startup to small cap, and their investors with the tools needed to navigate capital raising.” — U.S. Securities and Exchange Commission, Resources for Small Businesses (accessed July 28, 2026)
Private companies typically raise under exemptions from SEC registration. The SEC’s exempt-offerings overview (accessed July 28, 2026) describes, among other pathways, Regulation Crowdfunding for offerings of up to $5 million through a registered broker-dealer or funding portal, Regulation A for offerings of up to $75 million, and intrastate offerings under Rules 147 and 147A that raise money within one state without concurrent federal registration — which is where state securities rules take the lead. Rules, thresholds, and pathway requirements change; a securities attorney should confirm the legal path. This article covers only the finance record that reviewers request. Notably, the SEC Office of the Advocate for Small Business Capital Formation opens its capital-raising building blocks (page last reviewed April 27, 2026; accessed July 28, 2026) with financial statements under “Getting Ready to Raise Capital” — the record comes before the pitch.
Lenders review for repayment. The U.S. Small Business Administration (SBA) guarantees loans made by partner lenders rather than lending directly in most programs, and its loans page (accessed July 28, 2026) notes that businesses normally must meet SBA size standards, show ability to repay, and have a sound business purpose. On document requirements:
“Lenders and loan programs have unique eligibility requirements.” — U.S. Small Business Administration
The same page adds that eligibility generally turns on what the business does to receive its income, the character of its ownership, and where the business operates.
SBA-guaranteed loan sizes range from $500 to $5.5 million per the same page, and each lender provides its own document list — so treat every checklist here as preparation, not a substitute for the actual request list.
Name your accounting basis on every pack. Investors generally analyze accrual-basis statements prepared with U.S. Generally Accepted Accounting Principles (GAAP) in mind, while many small businesses keep cash-basis or tax-basis books. Those are different views of the same business, and a diligence pack that silently mixes them creates confusion. Label each statement with its basis (US GAAP-style accrual, cash, or tax basis), and keep a bridge between them. If your team needs a refresher on how the balance sheet, income statement, and cash flow statement connect, start with our guide to decoding financial statements.
What goes in the data room?
A data room is a shared folder with an index. The index below is the RFS working structure for a small-business raise; adjust it to the actual request list.
Table 1: Data-room index for a small-business raise (RFS working structure).
| # | Folder | Contents | Primary source |
|---|---|---|---|
| 01 | Financial statements | Monthly income statement, balance sheet, cash flow statement; year-end packages | Accounting system, closed periods |
| 02 | Reconciliations | Bank, credit card, loan, accounts receivable (AR), accounts payable (AP), payroll reconciliations by month | Reconciliation workpapers |
| 03 | Tax | Filed federal and state income tax returns, quarterly payroll filings, sales tax filings | Signed, filed copies |
| 04 | Revenue detail | Revenue by customer, contract, or product line; deferred revenue schedule | Billing and invoicing system |
| 05 | Expenses and AP | Vendor detail, recurring contracts, lease agreements | AP ledger and contracts |
| 06 | Debt and equity | Loan agreements, repayment schedules, capitalization table, prior investment documents | Executed agreements |
| 07 | Metrics pack | Written metric definitions with monthly values (see Table 3) | Metrics workbook |
| 08 | Forecast and plan | Operating model, assumptions, budget vs. actual history | Planning model |
| 09 | Compliance | Business licenses, insurance, required registrations | Issuing authorities |
| 10 | Issue log | Known issues with status and remediation (see Table 4) | Owner-maintained |
Interpretation: the index is itself evidence. A reviewer who can navigate from a folder number to a source document in one click reads the business as controlled; a reviewer who receives a single 400-file dump reads the opposite. Keep the index to one page and version it.
Do the books tie out?
Tie-outs are the heart of financial diligence: every material balance should trace to an external or subsidiary record. Work these checks monthly, in this order:
- Bank and credit cards — book cash equals the reconciled bank balance, with every reconciling item identified and dated.
- Accounts receivable (AR) — the AR aging total equals the balance-sheet AR figure; invoices trace to the ledger.
- Accounts payable (AP) — the AP aging total equals the balance-sheet AP figure.
- Payroll — payroll expense per the books agrees with quarterly payroll filings and payroll-provider reports.
- Tax — filed federal and state returns reconcile to the books through a documented book-to-tax bridge. Differences are normal (depreciation methods, for example); unexplained differences are the problem.
- Debt — loan balances per the books agree with lender statements, including accrued interest.
The worked example below is a hypothetical illustration with made-up inputs for a fictional US services company tying out one month of accrual-basis revenue.
Table 2: Worked revenue tie-out, June 2026 (made-up inputs, accrual basis).
| Line | Source | Amount (USD) |
|---|---|---|
| Opening AR, June 1 | AR aging | $31,500 |
| Invoices issued in June (= accrual revenue) | Invoice ledger | $102,400 |
| Cash collected in June | Bank deposits | $98,100 |
| Closing AR, June 30 (computed) | $31,500 + $102,400 − $98,100 | $35,800 |
| AR increase (computed) | $35,800 − $31,500 | $4,300 |
| Check: revenue − collections | $102,400 − $98,100 | $4,300 |
Interpretation: the income statement shows $102,400 of June revenue while the bank shows $98,100 collected; the $4,300 gap is fully explained by the $4,300 increase in receivables, so the month ties out. An investor can now trace one number — revenue — from the invoice ledger to the statement, to the bank, to the AR schedule. A month that cannot be traced this way (a gap with no identified reconciling item) is a red flag that slows or reprices a deal. One anonymized RFS engagement involved an early-stage company whose statements filed with the Internal Revenue Service (IRS) did not match its bank records; the work, described in our case study on reconciling statements before a raise, was to reconcile and re-prepare the financials and refine the investor materials, after which the company went on to raise growth capital. That is one client’s experience, not a promised result — but the pattern generalizes: mismatches surface in diligence, so find and fix them first.
How much monthly reporting history do you need?
No statute fixes how much history an investor must receive; investors and lenders set their own lists. As a planning assumption — not a rule — prepare to produce monthly statements covering at least the trailing 24 months, plus year-to-date and a trailing-twelve-month summary, and expect some reviewers to ask for three years. Confirm the actual list before over-producing.
Two floors are set by law, and they are lower than what diligence expects. Federally, the IRS requires records supporting an item on a tax return to be kept until that return’s period of limitations runs out — generally 3 years, 6 years if more than 25% of gross income was omitted, 7 years for a bad-debt or worthless-securities claim, and indefinitely if no return was filed or the return was fraudulent, per the IRS record-retention guidance (accessed July 28, 2026). On payroll:
“Keep employment tax records for at least 4 years after the date that the tax becomes due or is paid, whichever is later.” — Internal Revenue Service
The same IRS page advises keeping copies of filed tax returns, and states may impose longer retention rules — keep the longer of the two. Diligence asks for more than the tax floor because reviewers want trend history, not just audit survival: a raise built on two clean months reads as a coincidence; a raise built on 24 closed months reads as a process.
A closed month, for this checklist, means: bank and credit cards reconciled, revenue and expense cutoffs applied, accrual adjustments posted, and a reviewer sign-off recorded. Twelve “closed” months in a folder is a claim an investor can test; twelve exports from an accounting system is not.
Which metrics will investors test, and how are they defined?
Investors test definitions before they test values — a founder quoting “runway” that cannot be recomputed from the statements loses the room. Define each metric in writing, state the formula, and keep a monthly series that ties to the data-room statements. The metrics below are defined in plain language; these are conventions, not legal definitions, so state yours and apply them consistently.
Table 3: Metric definitions for a diligence pack (formulas in plain language).
| Metric | Plain-language definition | Formula |
|---|---|---|
| Revenue (accrual) | Income earned when goods or services are delivered, regardless of payment date | Sum of invoices/earned amounts in period |
| Gross margin | Share of revenue left after direct costs | (Revenue − cost of goods sold) ÷ revenue |
| EBITDA | Operating earnings before financing and non-cash charges | Net income + interest + taxes + depreciation + amortization |
| MRR / ARR | Monthly recurring revenue; annualized recurring revenue | ARR = MRR × 12 |
| Net burn | Net cash consumed per month while loss-making | Monthly cash out − monthly cash in |
| Runway | Months of operation cash on hand can fund | Cash ÷ monthly net burn |
| DSCR | Debt service coverage ratio: income available to cover loan payments | Net operating income ÷ annual debt service |
Worked numbers, all hypothetical with made-up inputs: cash of $420,000 with monthly net burn of $35,000 gives a runway of $420,000 ÷ $35,000 = 12.0 months. Net operating income of $180,000 against annual debt service of $150,000 gives a DSCR of $180,000 ÷ $150,000 = 1.20× — $1.20 of income per $1.00 of loan payments. Revenue of $102,400 with $61,440 of direct costs gives a gross margin of $40,960 ÷ $102,400 = 40.0%. Each figure recomputes exactly from the table’s formula, which is the standard your pack should meet.
For larger checks, investors may commission a quality of earnings (QoE) analysis — an independent review that tests whether reported earnings are repeatable, separating ongoing results from one-time items and owner-specific choices. Smaller raises often face a lighter, informal version of the same questions. A hypothetical normalization: reported EBITDA of $310,000, plus $40,000 of owner compensation above a market rate, minus a $15,000 one-time gain, gives normalized EBITDA of $310,000 + $40,000 − $15,000 = $335,000 (made-up inputs). Whether or not a formal QoE happens, do the normalization yourself first and disclose the adjustments. In one RFS engagement, a digital media management company raising growth capital needed exactly this kind of investment-grade preparation: RFS built the operating plan, financial model, discounted cash flow (DCF) valuation, industry overview, and investor materials, and fielded questions from multiple funds directly until the raise closed, per the capital-advisory case study — one client’s experience, not a promised outcome.
What belongs in the issue log?
The issue log converts “we found problems” from a diligence failure into evidence of management control. Every known weakness gets one row, an owner, and a plan; nothing material stays out of the log.
Table 4: Issue-log format with hypothetical example rows.
| Issue | Discovered | Owner | Status | Remediation | Target date |
|---|---|---|---|---|---|
| Merchant account unreconciled since March | Jun 2026 close | Bookkeeper | In progress | Rebuild deposits from processor reports | Jul 31, 2026 |
| Owner loan undocumented | Data-room assembly | Owner + counsel | Open | Execute note with terms | Aug 15, 2026 |
| Personal expenses in books | Tie-out review | Accountant | Remediated | Reclassed; policy adopted | Closed Jun 30, 2026 |
| Two quarterly payroll filings missing from folder | Data-room assembly | Payroll provider | In progress | Obtain filed copies | Jul 20, 2026 |
Interpretation: reviewers assume an empty issue log means an unexamined business, not a perfect one. A short log with honest statuses and closed items is a credibility asset; a long log of open, unowned items is a signal to delay the raise until the remediation column moves.
What does a 90-day preparation timeline look like?
The timeline below is a planning cadence for an owner starting from reasonably current books, not a requirement — adjust it to the actual request list and your close cycle.
Table 5: 90-day owner timeline to diligence readiness.
| Phase | Days | Actions | Output |
|---|---|---|---|
| Catch up | 1–15 | Close all open months; finish outstanding bank and credit-card reconciliations | Clean, closed periods |
| Assemble | 16–35 | Build the Table 1 index; gather filed returns, agreements, and compliance documents | Indexed data room |
| Define | 36–55 | Write metric definitions; build the monthly series for Table 3 metrics | Metrics pack |
| Tie out | 56–75 | Run the Table 2 checks on every material balance; open the issue log; remediate quick items | Tie-out workpapers, live issue log |
| Rehearse | 76–90 | Dry-run investor Q&A with an advisor; fill gaps; finalize the pack | Diligence-ready data room |
Interpretation: the longest poles are almost always catch-up bookkeeping and remediation, not document assembly — which is why the timeline front-loads the close. A raise launched before phase 1 finishes borrows credibility it cannot repay.
FAQs
Is financial due diligence legally required before a small business can raise money?
There is no single federal “due diligence checklist” statute for private companies. What is regulated is the offering itself: federal securities law administered by the SEC, plus state securities rules, govern how securities are offered and sold, with exemptions such as those on the SEC’s exempt-offerings overview. Lenders set their own underwriting conditions. Investors and lenders then impose diligence as a practical condition of writing the check. Confirm the legal path with securities counsel.
Do my financial statements need to be audited?
It depends on the pathway, the investor, and the size of the raise. Many small private raises proceed on company-prepared statements; certain regulated offering pathways and larger institutional checks impose higher assurance requirements. Confirm what your specific investors, lender, and offering pathway require before paying for an audit.
My books are cash-basis — is that a problem?
Not automatically, but expect accrual-based questions. Investors generally analyze accrual-basis, GAAP-oriented statements, and a cash-basis pack cannot answer questions about receivables, payables, or deferred revenue. Name your basis on every statement, keep a bridge between bases, and consider converting to accrual books before the raise rather than during it.
How long must I keep the underlying records?
Federally, until the period of limitations for the related tax return runs out — generally 3 years, 6 years for a substantial income omission, 7 years for bad-debt or worthless-securities claims, and at least 4 years for employment tax records, per IRS guidance. States may require longer, and lenders or investors may ask for more history than the tax floor.
What if I find an error while preparing?
Fix it, and record it in the issue log with what changed and why. If a filed tax return is affected, work with a qualified tax professional on whether an amendment is needed. Corrected errors with documentation are routine in diligence; errors the reviewer finds first are the expensive kind.
The bottom line
The action: close every open month, build the indexed data room, tie out every material balance to an external record, write down your metric definitions with monthly values, keep an honest issue log, and rehearse the Q&A — then hand reviewers the actual request list, not a document dump. If your books need catch-up work or your team lacks the capacity to run this alongside the business, our Remote CFO services help owners prepare for diligence — from the close process through the investor Q&A — and the Remote CFO services hub maps the related guides.
