Preparing Your Small Business for an Audit or M&A Due Diligence

AUDIT PREPARATION VS. M&A DUE DILIGENCE

These processes are not the same.

A financial statement audit involves an independent auditor obtaining and evaluating evidence to support conclusions about financial statements under applicable professional standards.

M&A due diligence has a different purpose.

The buyer is evaluating the business and the proposed transaction.

The buyer may examine financial information to understand earnings, working capital, debt, cash, risks, and other factors relevant to the transaction.

The two processes can overlap in the records they examine.

That means good financial audit preparation can also improve general transaction readiness.

WHY BOOKKEEPING MATTERS TO BUSINESS VALUATION

Financial records are one of the foundations of business valuation.

The U.S. Small Business Administration notes that business valuation may consider approaches based on income, market comparisons, and assets. It also emphasizes accurately valuing business property and other assets when preparing to sell a business.

Regardless of the valuation method used, unreliable accounting records can make it harder to understand the financial performance of the business.

For example, unclear bookkeeping may make it difficult to determine:

• Actual revenue
• Normal operating expenses
• Owner-related expenses
• Recurring profitability
• Working capital
• Outstanding liabilities
• Asset values

This is why business valuation bookkeeping should not be treated as a last-minute cleanup project.

START WITH A COMPLETE FINANCIAL RECORDS REVIEW

Before an audit or transaction, review the company's accounting records from the ground up.

Start with the major financial statements:

Income Statement

Review revenue, cost of sales, gross profit, operating expenses, and net income.

Look for unusual fluctuations.

Balance Sheet

Review:

• Cash
• Accounts receivable
• Inventory
• Fixed assets
• Accounts payable
• Accrued liabilities
• Debt
• Equity

The balance sheet is particularly important because it provides a snapshot of assets, liabilities, and equity.

Cash Flow Statement

Understand where cash is coming from and where it is going.

If your business does not routinely prepare a cash flow statement, at least make sure you can clearly explain major cash movements.

RECONCILE EVERY IMPORTANT ACCOUNT

Bank reconciliations are one of the basic foundations of clean accounting.

Review:

• Business bank accounts
• Credit cards
• Loans
• Payment processors
• Investment accounts
• Other material balance sheet accounts

Unreconciled accounts can create questions during an audit or due diligence review.

If the accounting system shows $250,000 in cash but the bank records do not support that balance, the difference needs to be investigated.

The same principle applies to receivables, payables, loans, and other accounts.

REVIEW ACCOUNTS RECEIVABLE

Accounts receivable can have a significant effect on how a buyer evaluates the financial condition of a business.

Review:

• Customer balances
• Invoice dates
• Payment terms
• Aging
• Overdue balances
• Bad debt history
• Customer concentration

A large receivable balance does not automatically mean the business has strong collectible assets.

The quality and collectability of those receivables matter.

Also, be prepared to explain unusual balances.

REVIEW ACCOUNTS PAYABLE AND ACCRUED EXPENSES

The other side of working capital deserves similar attention.

Review outstanding:

• Vendor invoices
• Credit card balances
• Payroll liabilities
• Taxes payable
• Accrued expenses
• Other short-term obligations

Make sure liabilities are recorded consistently.

In an M&A transaction, working capital can be particularly important because purchase agreements may define closing working capital and establish post-closing adjustment procedures. SEC-filed transaction agreements illustrate how closing working capital and related financial records can become part of transaction mechanics.

CLEAN UP OWNER AND PERSONAL EXPENSES

Small businesses sometimes contain expenses that are not directly related to normal business operations.

Examples might include:

• Personal expenses paid through the business
• Owner travel
• Personal vehicle costs
• Family-related expenses
• Nonrecurring purchases
• Discretionary owner benefits

These transactions should be properly identified and classified according to the applicable accounting and tax treatment.

Do not simply remove expenses because you believe they will improve valuation.

Instead, maintain clear documentation and work with the appropriate accounting and transaction advisors to determine how unusual or owner-specific items should be presented.

SEPARATE RECURRING AND NONRECURRING EXPENSES

A buyer may want to understand the sustainable economics of the business.

That makes it useful to identify unusual expenses separately.

Examples might include:

• One-time legal costs
• Major equipment purchases
• Certain restructuring expenses
• Unusual consulting projects
• One-time relocation costs
• Nonrecurring technology implementation

The treatment of these items depends on the transaction and accounting methodology.

The important point is to document what happened and why.

Do not assume that every unusual expense should automatically be added back to earnings.

REVIEW REVENUE CAREFULLY

Revenue is often one of the most important areas in financial due diligence.

Review:

• Revenue by customer
• Revenue by product or service
• Recurring vs. one-time revenue
• Contract terms
• Discounts
• Refunds
• Credits
• Deferred revenue where applicable
• Customer concentration

The goal is to make sure revenue reported in the financial records can be supported by underlying business activity and documentation.

If revenue has grown significantly, be prepared to explain what drove that growth.

CHECK CUSTOMER CONCENTRATION

A business can have strong revenue while relying heavily on a small number of customers.

Review how much revenue comes from the largest customers.

For example:

• Top customer percentage of revenue
• Top five customers
• Customer retention
• Contract length
• Renewal rates
• Major customer changes

Customer concentration does not automatically make a business less valuable.

But it can be an important factor for buyers evaluating revenue stability and risk.

ORGANIZE TAX RECORDS

Tax records are an important part of transaction and financial preparation.

Create an organized file containing applicable:

• Federal tax returns
• State tax returns
• Local tax filings
• Payroll tax filings
• Sales tax filings
• Property tax records
• Tax notices
• Tax payment records
• Correspondence with tax authorities

Make sure the tax returns are consistent with the underlying accounting records.

If there are significant differences, understand why they exist.

REVIEW PAYROLL RECORDS

Payroll can create both financial and compliance questions.

Review:

• Employee lists
• Compensation
• Payroll reports
• Payroll tax filings
• Benefits
• Contractor payments
• Bonus arrangements
• Owner compensation
• Employment agreements where applicable

If the business uses independent contractors, make sure the records and classification process are properly documented.

REVIEW DEBT AND FINANCING

Prepare a complete list of company debt.

For each significant obligation, identify:

• Lender
• Original amount
• Current balance
• Interest rate
• Maturity date
• Payment terms
• Collateral
• Guarantees
• Covenants
• Outstanding fees

Also collect the underlying loan agreements.

A buyer should be able to understand what financial obligations may transfer, remain with the seller, or require specific treatment under the transaction documents.

PREPARE AN ASSET REGISTER

Create a current list of major business assets.

Depending on the business, this may include:

• Equipment
• Vehicles
• Computers
• Machinery
• Furniture
• Inventory
• Software
• Intellectual property
• Real estate
• Other significant assets

Compare the asset register with the accounting records.

Investigate assets that appear in the books but no longer exist and assets that exist but are not properly recorded.

REVIEW INVENTORY

If the business carries inventory, prepare for detailed questions.

Review:

• Inventory quantities
• Inventory valuation
• Obsolete inventory
• Slow-moving inventory
• Inventory adjustments
• Purchase records
• Costing methods
• Physical counts

Inventory can affect both financial reporting and working capital calculations.

REVIEW WORKING CAPITAL

Working capital often receives significant attention in M&A transactions.

A simplified calculation is:

Working Capital = Current Assets − Current Liabilities

However, transaction documents may define working capital differently.

For example, the purchase agreement may specify which accounts are included or excluded and which accounting principles or methodologies should be used.

This is important because the final working capital calculation can affect the purchase price adjustment.

SEC-filed acquisition agreements commonly contain specific provisions governing closing working capital, supporting schedules, accounting methods, and post-closing adjustments.

Therefore, sellers should understand the transaction-specific definition rather than relying only on a generic accounting formula.

BUILD AN M&A DUE DILIGENCE CHECKLIST

A practical m&a due diligence checklist can help organize the preparation process.

Financial statements

• Monthly income statements
• Balance sheets
• Cash flow statements where available
• Trial balances
• General ledger
• Budgets
• Forecasts
• Management reports

Banking and cash

• Bank statements
• Bank reconciliations
• Credit card statements
• Merchant processor statements
• Investment account records

Revenue

• Revenue by customer
• Revenue by product or service
• Major contracts
• Customer concentration
• Recurring revenue information
• Refunds and credits

Accounts receivable

• A/R aging
• Customer balances
• Collection history
• Bad debt information

Accounts payable

• A/P aging
• Major vendor balances
• Outstanding invoices
• Accrued expenses

Taxes

• Federal returns
• State returns
• Local returns
• Payroll tax filings
• Sales tax filings
• Tax notices
• Tax correspondence

Debt

• Loan agreements
• Current balances
• Payment schedules
• Guarantees
• Security agreements

Payroll

• Employee roster
• Compensation records
• Payroll reports
• Benefits
• Contractor records

Assets

• Fixed asset register
• Equipment records
• Vehicle records
• Inventory records
• Property records
• Intellectual property documentation

Corporate and legal records

• Formation documents
• Ownership records
• Material contracts
• Licenses
• Insurance
• Litigation information
• Intellectual property records

The exact checklist should be customized to the business and transaction.

CREATE A SECURE DATA ROOM

If the business is entering an M&A process, documents should be organized so authorized parties can review them efficiently.

A typical data room may contain separate folders for:

• 1. Corporate documents
• 2. Financial statements
• 3. Tax records
• 4. Banking
• 5. Revenue and customers
• 6. Accounts receivable
• 7. Accounts payable
• 8. Employees and payroll
• 9. Assets
• 10. Debt
• 11. Contracts
• 12. Legal matters
• 13. Insurance
• 14. Intellectual property

Do not upload sensitive information casually.

Access should be controlled and appropriate confidentiality protections should be in place.

PREPARE EXPLANATIONS FOR MAJOR VARIANCES

A buyer or auditor may notice changes in the financial statements.

For example:

• Revenue increased 40%.
• Payroll increased 25%.
• Marketing expenses doubled.
• Gross margin declined.
• Accounts receivable increased significantly.

Prepare clear explanations for material changes.

Supporting schedules can make the review easier.

For example:

Revenue increase

New customers + expansion from existing customers + pricing changes

Payroll increase

Five new employees + salary adjustments + benefits

The exact explanation should match the underlying records.

DO NOT WAIT UNTIL A BUYER FINDS PROBLEMS

One of the biggest advantages of preparation is finding issues before another party finds them.

For example, your internal review might discover:

• Unreconciled bank accounts
• Old receivables
• Unrecorded liabilities
• Incorrect expense classifications
• Missing contracts
• Inconsistent revenue records
• Duplicate vendors
• Outdated asset records

The earlier these issues are identified, the more time there is to investigate and correct them appropriately.

AVOID LAST-MINUTE FINANCIAL CLEANUP

Trying to reconstruct several years of accounting records immediately before a transaction can create unnecessary pressure.

It can also make it difficult to determine whether historical results are reliable.

A better approach is to maintain clean records continuously.

The SBA emphasizes that accurate bookkeeping supports a business's accounting and financial systems and helps owners understand financial performance and cash flow.

Good bookkeeping is therefore not just about tax filing.

It can also contribute to transaction readiness.

BUILD A MONTHLY FINANCIAL REVIEW PROCESS

You do not need to wait for an audit or sale process to review your records.

A monthly review can include:

Accounting close

Complete reconciliations and necessary adjustments.

Financial statement review

Examine the income statement and balance sheet.

Cash review

Compare actual cash with expectations.

A/R review

Identify overdue and potentially uncollectible balances.

A/P review

Review upcoming obligations.

Tax review

Confirm that required filings and payments are being handled.

Variance review

Investigate significant differences from the budget or previous periods.

This creates a more reliable financial history.

WHAT BUYERS OFTEN WANT TO UNDERSTAND

During M&A due diligence, the buyer's questions can extend beyond whether the books balance.

They may want to understand:

• Is the revenue sustainable?
• Are margins stable?
• Are customer relationships durable?
• Are there unusual expenses?
• What liabilities exist?
• How much working capital does the business require?
• Are the financial statements consistent?
• What risks could affect future performance?

The specific questions will depend on the transaction.

The better organized the underlying records are, the easier it can be to answer legitimate questions accurately.

FINANCIAL AUDIT PREPARATION CHECKLIST

If you are preparing for an audit, focus on the quality and availability of supporting evidence.

Make sure you can support significant balances and transactions with appropriate documentation.

This may include:

• Bank statements
• Invoices
• Receipts
• Contracts
• Payroll records
• Loan documents
• Fixed asset records
• Inventory records
• Tax filings
• Reconciliations
• Supporting schedules

AICPA guidance emphasizes that auditors evaluate information to determine whether sufficient appropriate audit evidence has been obtained.

That means good documentation is not simply administrative paperwork.

It supports the financial information being examined.

WHEN TO BRING IN PROFESSIONAL SUPPORT

Professional accounting support can be valuable before an audit or M&A process, particularly when the business has complex records or limited internal finance resources.

Consider getting support when:

• Financial records need cleanup
• Several years of accounting need to be reviewed
• The company is preparing for a sale
• A buyer has issued a due diligence request
• Working capital needs to be analyzed
• Revenue recognition is complex
• The company has multiple entities
• Tax records need reconciliation
• Management needs normalized financial reporting
• The business is preparing for valuation

The appropriate professionals may include an accountant, CPA, valuation professional, attorney, tax advisor, or M&A advisor depending on the situation.

No single professional should be assumed to cover every aspect of an audit or transaction.

FINAL THOUGHTS

Preparing for an audit or M&A due diligence should not begin when the request arrives.

It should begin with the way your business maintains its financial records every month.

Accurate bookkeeping, reconciled accounts, organized documentation, clear financial statements, and consistent reporting can make it easier to understand the business and respond to detailed financial questions.

For owners considering a future sale, strong business valuation bookkeeping can also provide a cleaner foundation for understanding the company's financial performance and discussing valuation.

For an audit, organized documentation helps support the financial information being examined.

For M&A, a well-maintained financial history can make the due diligence process more structured and easier to navigate.

The goal is not to make your records look perfect.

The goal is to make them accurate, supportable, understandable, and ready for review.
