Due diligence is commonly associated with acquisitions, investments, financing, partnerships, commercial real estate transactions, and major business restructurings. The scope depends on the transaction and the information available.

Why Commercial Due Diligence Matters

A transaction may appear financially attractive based on limited information, while deeper review can reveal obligations or risks that require further analysis.

Commercial due diligence can help examine:

• Financial performance

• Revenue and earnings quality

• Assets and liabilities

• Contracts

• Operations

• Customers and suppliers

• Employees and organizational structure

• Regulatory compliance

• Litigation exposure

• Technology and cybersecurity

• Intellectual property

• Tax matters

• Insurance coverage

• Business continuity

The purpose is generally to develop a more complete understanding of the transaction rather than relying solely on management summaries or headline financial figures.

Financial Due Diligence

Financial review is often one of the central components of commercial due diligence.

Documents may include:

• Income statements

• Balance sheets

• Cash-flow statements

• General ledgers

• Bank records

• Accounts receivable

• Accounts payable

• Tax filings

• Budgets

• Forecasts

• Debt schedules

• Capital expenditure records

Reviewers may examine whether reported financial performance is consistent with underlying records and whether unusual or nonrecurring items materially affect results.

Revenue and Earnings Analysis

Revenue should be evaluated in the context of how the business actually generates income.

Analysis can include:

• Revenue by product or business segment

• Recurring versus nonrecurring revenue

• Customer concentration

• Contract duration

• Revenue recognition practices

• Refunds or adjustments

• Historical growth

• Gross margins

• Operating margins

• Earnings adjustments

A detailed review can help distinguish sustainable operating performance from temporary or unusual financial effects.

Working Capital and Cash Flow

Working capital analysis examines the relationship between short-term assets and obligations.

Relevant areas may include:

• Accounts receivable aging

• Inventory levels

• Accounts payable

• Accrued expenses

• Deferred revenue

• Operating cash flow

• Seasonal fluctuations

• Working-capital requirements

Cash-flow analysis can also identify differences between reported earnings and actual cash generation.

Operational Due Diligence

Financial information provides only part of the picture. Operational review examines how the business functions in practice.

Areas can include:

• Business processes

• Production capacity

• Facilities

• Equipment

• Technology systems

• Supply chains

• Procurement

• Inventory management

• Quality controls

• Workforce structure

• Operational dependencies

• Business continuity

The review should consider whether existing operations can support the organization's current activities and anticipated changes.

Customer and Supplier Risk

Customer and supplier relationships can materially affect business stability.

Due diligence may examine:

• Customer concentration

• Major customer agreements

• Contract renewal dates

• Supplier concentration

• Supplier dependencies

• Pricing provisions

• Termination rights

• Geographic exposure

• Performance obligations

• Dispute history

Heavy reliance on a small number of customers or suppliers can create concentration risk that should be understood before a transaction.

Contract Review

Contracts can create important rights and obligations that may continue after a transaction.

Review areas may include:

• Major customer contracts

• Supplier agreements

• Lease agreements

• Financing documents

• Licensing agreements

• Technology agreements

• Distribution arrangements

• Partnership agreements

• Change-of-control provisions

• Termination provisions

• Renewal provisions

• Assignment restrictions

Some agreements may require consent or notification when ownership or control changes.

Legal and Regulatory Risk

Due diligence can identify legal and regulatory matters that may affect a transaction.

Potential review areas include:

• Pending litigation

• Regulatory investigations

• Licenses

• Permits

• Compliance records

• Intellectual-property disputes

• Employment claims

• Environmental obligations

• Data-protection requirements

• Industry-specific regulations

The relevant requirements depend on the industry, location, entity structure, and transaction.

Tax Due Diligence

Tax review can examine historical filings and potential liabilities.

Areas may include:

• Federal tax filings

• State and local taxes

• Payroll taxes

• Sales and use taxes

• Property taxes

• Tax audits

• Tax disputes

• Deferred tax matters

• Tax credits

• International tax obligations

Tax exposure should be evaluated with current rules and the specific transaction structure in mind.

Technology and Cybersecurity Review

Technology systems can represent both business assets and operational risks.

A technology review may examine:

• IT infrastructure

• Software licenses

• Data architecture

• Cybersecurity controls

• Access management

• Backup procedures

• Incident history

• Cloud systems

• Vendor dependencies

• Software contracts

• Data-protection practices

Cybersecurity incidents or weak controls can affect operations, compliance obligations, financial exposure, and transaction planning.

Human Resources and Workforce Review

Workforce analysis can provide information about organizational continuity and potential employment obligations.

Review areas may include:

• Employee agreements

• Compensation structures

• Benefit arrangements

• Key personnel

• Workforce concentration

• Employment claims

• Contractor relationships

• Incentive arrangements

• Employee turnover

• Policies and procedures

Key-person dependencies may require additional continuity planning.

Insurance and Risk Transfer

Insurance records can help identify how significant business risks are currently addressed.

Documents may include:

• General liability policies

• Property coverage

• Cyber coverage

• Professional liability coverage

• Directors and officers coverage

• Workers' compensation records

• Claims history

• Policy limits

• Major exclusions

Insurance coverage should be evaluated alongside the actual risk profile rather than assumed to eliminate potential exposure.

Asset and Property Review

Physical and intangible assets may require separate examination.

Asset review can include:

• Real estate

• Equipment

• Vehicles

• Inventory

• Intellectual property

• Software

• Licenses

• Trademarks

• Domain names

• Data assets

• Specialized machinery

Ownership, condition, valuation, liens, restrictions, and documentation can all be relevant.

Risk Assessment Framework

A structured risk register can help organize findings.

Risks can then be categorized according to their potential significance, probability, available evidence, and possible mitigation measures.

Due Diligence Data Room

A secure data room can organize documents for review by authorized parties.

Typical categories include:

• Corporate records

• Financial statements

• Tax records

• Contracts

• Property records

• Employee documents

• Insurance policies

• Regulatory documents

• Intellectual-property records

• Technology documentation

• Litigation records

A well-organized data room can make it easier to track missing documents and maintain a record of reviewed information.

Recent Developments

Commercial due diligence increasingly includes technology, cybersecurity, data privacy, supply-chain resilience, and environmental considerations.

Artificial intelligence can also create new review questions, including:

• Ownership of AI-generated or AI-assisted materials

• Use of third-party AI platforms

• Confidential information exposure

• Data-processing practices

• Software licensing

• Model-related dependencies

• Internal AI governance

Organizations involved in transactions may also examine climate-related exposure, supply-chain concentration, and operational resilience where these factors could materially affect the business.
