Acquiring an existing business can provide an opportunity to enter a new market, expand operations, acquire valuable assets or strengthen an organisation’s competitive position. However, a business acquisition also involves financial, legal, tax and operational risks that may not be immediately visible.

A company may appear profitable, have an established customer base and demonstrate strong revenue growth, but its actual financial position could be affected by outstanding loans, pending litigation, tax disputes, contractual obligations or inaccurate financial records.

This is why business acquisition due diligence is an essential step before completing a merger, acquisition or business purchase.

Due diligence involves a systematic examination of the target business to verify information provided by the seller, identify potential liabilities and evaluate whether the proposed transaction makes commercial and financial sense.

For entrepreneurs, investors, business owners and corporate decision-makers, conducting due diligence before acquiring a business helps reduce uncertainty, assess business value and negotiate appropriate transaction terms.

This guide explains the important financial, legal, tax, commercial and operational checks buyers should consider before acquiring a business in India.

What Is Due Diligence in a Business Acquisition?

Business acquisition due diligence is the process of investigating and verifying a target company’s financial records, legal position, tax compliance, ownership, assets, contracts and business operations before completing an acquisition.

The purpose is to establish whether the information shared by the seller accurately represents the business and whether any undisclosed risks could affect the proposed transaction.

For example, an investor considering the acquisition of a manufacturing company may initially focus on its annual revenue, profitability, production capacity and customer relationships.

However, a detailed review may reveal:

• Outstanding loans that were not clearly disclosed.
• Pending tax assessments or statutory dues.
• Machinery that is leased rather than owned.
• Significant overdue customer receivables.
• Disputes involving important commercial contracts.
• Dependence on a small number of customers.
• Intellectual property that is not legally owned by the company.

These findings can influence the acquisition price, deal structure and decision to proceed.

Major Types of Due Diligence

A comprehensive M&A due diligence exercise generally involves several interconnected review areas.

The scope of the review should depend on the size, nature, structure and complexity of the proposed acquisition.

Why Is Due Diligence Important Before Buying a Business?

A business acquisition involves more than purchasing shares, assets or an established brand. The buyer may also take on existing contractual obligations, financial exposure and operational challenges.

A structured due diligence process helps buyers make informed decisions before committing significant capital.

Identifies Undisclosed Financial Liabilities

A business may have outstanding loans, unpaid supplier invoices, employee dues, guarantees or contingent liabilities that are not immediately apparent from its reported financial performance.

A financial review helps identify these exposures and assess their potential impact on the acquisition.

Verifies Financial Performance and Business Value

Reported revenue and profitability should be supported by accounting records, bank statements, tax filings and commercial documentation.

Financial due diligence helps buyers understand whether the reported earnings are sustainable and whether the proposed acquisition valuation is reasonable.

Confirms Ownership of Assets and Business Interests

Buyers should verify whether the target business legally owns the assets, shares, intellectual property and other rights being represented by the seller.

This is particularly important when acquiring businesses with significant machinery, property, trademarks, technology or contractual rights.

Identifies Legal Disputes and Compliance Issues

Pending court cases, arbitration proceedings, regulatory investigations and statutory non-compliance may create financial and operational risks.

A legal review helps identify these matters before the transaction is completed.

Evaluates Business Continuity

A company may depend heavily on a few customers, key employees, suppliers or promoters.

Understanding these dependencies helps buyers assess whether the business can continue operating successfully after the acquisition.

Supports Better Acquisition Negotiations

Due diligence findings can help buyers:

• Reassess the proposed purchase price.
• Request additional warranties and indemnities.
• Negotiate payment or escrow arrangements.
• Seek additional approvals or contractual consents.
• Reconsider the transaction if material risks cannot be addressed.

In this way, due diligence becomes an important part of the overall business acquisition process.

Financial Due Diligence Checks Before Acquiring a Business

Financial due diligence examines the target company’s financial records and performance to determine whether its reported financial position is reliable and sustainable.

The objective is not simply to verify accounting figures. Buyers must also understand the quality of earnings, working capital requirements, debt exposure and financial risks that may affect future performance.

Review Historical Financial Statements

The first step is to examine the target company’s financial statements for previous financial years.

Important documents include:

• Audited balance sheets.
• Profit and loss statements.
• Cash flow statements.
• Notes to accounts and financial statement disclosures.
• Auditor’s reports and audit qualifications.
• Management accounts and financial reports.
• Trial balances and general ledgers.

The review should focus on identifying unusual financial movements, inconsistent accounting practices and discrepancies between reported results and supporting records.

For example, a company may report increasing profits while its cash flow from operations continues to decline. This could indicate delayed collections, growing receivables or other working capital concerns.

Verify Revenue and Profitability

Reported revenue should be supported by actual business transactions.

Buyers should examine:

• Sales invoices and supporting contracts.
• Bank receipts and customer payment records.
• GST returns and relevant reconciliations.
• Revenue recognition policies.
• Credit notes, sales returns and discounts.
• Customer concentration and recurring revenue.
• Profit margins across products or services.

It is also important to distinguish recurring operating income from one-time gains, exceptional transactions and non-operating income.

A buyer may calculate adjusted EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortisation) to understand the operating earnings of the business after evaluating unusual or non-recurring items.

However, any adjustments should be supported by evidence rather than assumptions.

Examine Cash Flow and Working Capital

A profitable company may still face cash shortages if customer collections are delayed or significant amounts are tied up in inventory.

The buyer should examine:

Accounts Receivable

• Outstanding customer invoices.
• Overdue receivables.
• Customer payment history.
• Bad debt provisions.
• Disputed invoices and collection risks.

Accounts Payable

• Outstanding supplier payments.
• Overdue vendor balances.
• Contractual payment obligations.
• Unrecorded or disputed liabilities.

Inventory

• Stock valuation methods.
• Slow-moving and obsolete inventory.
• Physical stock verification.
• Inventory turnover.
• Differences between stock records and actual quantities.

Working Capital Requirements

Evaluate the amount of working capital needed to maintain normal business operations after acquisition.

This is especially important when negotiating a purchase price based on cash-free, debt-free terms or a normalised working capital adjustment.

Review Debt and Financial Liabilities

Existing financial obligations can materially affect the value of a business.

Important checks include:

• Outstanding bank loans and credit facilities.
• Loan agreements and repayment schedules.
• Interest obligations and default history.
• Security interests and charges over assets.
• Corporate and personal guarantees.
• Pledged shares or assets.
• Lease liabilities.
• Contingent liabilities and off-balance-sheet exposures.

Buyers should also examine whether the proposed change in ownership triggers lender consent, repayment or other contractual requirements.

Verify Assets and Inventory

A target company’s assets should be independently verified wherever practical.

The review may include:

• Fixed asset registers.
• Purchase invoices and ownership documents.
• Property title and encumbrance records.
• Machinery and equipment details.
• Depreciation and impairment records.
• Physical inventory verification.
• Insurance coverage.
• Asset leasing and financing arrangements.

A business may report substantial fixed assets in its balance sheet, but some assets may be obsolete, impaired, leased or subject to third-party claims.

The objective is to establish the actual existence, condition, ownership and financial value of important assets.

Legal Due Diligence Checks Before Acquiring a Business

Legal due diligence examines the target company’s legal status, ownership, contractual commitments, disputes, intellectual property and regulatory obligations.

While financial records help establish what a business earns and owes, legal checks help determine whether the company has the legal rights and authority to operate as represented.

This review should be conducted with qualified legal professionals, particularly for complex acquisitions and regulated industries.

Verify Company Ownership and Corporate Records

Before acquiring a company, buyers should establish who legally owns it and whether the seller has the authority to complete the transaction.

Important documents include:

• Certificate of incorporation.
• Memorandum and Articles of Association.
• Shareholding structure and capitalisation table.
• Share certificates and share transfer records.
• Register of members and other statutory registers.
• Board and shareholder resolutions.
• Annual returns and financial statement filings.
• Relevant Ministry of Corporate Affairs (MCA) records.
• Shareholder and investment agreements.

The review should identify existing share pledges, transfer restrictions, options, convertible securities and other rights that may affect ownership.

For share acquisitions, the buyer should also verify the seller’s title to the shares being transferred.

Review Contracts and Commercial Agreements

Material contracts can have a significant impact on the value and continuity of a business.

Buyers should examine:

• Major customer agreements.
• Supplier and distribution contracts.
• Employment and consultancy agreements.
• Loan and financing arrangements.
• Property leases.
• Franchise and licensing agreements.
• Technology and software contracts.
• Joint venture and shareholder agreements.

Pay particular attention to change-of-control clauses.

Some agreements may require prior consent from a customer, supplier, lender or other contractual party when ownership or control of the target business changes.

Other contracts may allow termination, renegotiation or modification following an acquisition.

Identifying these provisions early can help prevent unexpected disruption after closing.

Check Pending Litigation and Legal Disputes

Unresolved legal matters can create financial exposure and affect business continuity.

Review:

• Pending court cases.
• Arbitration proceedings.
• Legal notices and claims.
• Regulatory investigations.
• Disputes involving customers and suppliers.
• Employee and labour-related disputes.
• Property and ownership disputes.
• Intellectual property infringement claims.

The review should consider both the amount claimed and the possible business consequences.

For example, a dispute involving a key distribution agreement may threaten future revenue even if the direct financial claim is relatively small.

Verify Intellectual Property and Business Assets

Intellectual property may represent a significant part of the value of technology companies, consumer brands, manufacturers and service businesses.

Important checks include:

• Trademark registrations and applications.
• Patent ownership and registrations.
• Copyright ownership.
• Software development agreements.
• Domain names and digital assets.
• Technology licences.
• Intellectual property assignments.
• Existing infringement claims.

Buyers should confirm whether important intellectual property is owned by the target company or merely licensed from founders, employees, contractors or third parties.

If a business depends on proprietary software or a registered brand, unclear ownership can create serious post-acquisition risks.

Review Licences and Regulatory Compliance

Businesses must hold the registrations, approvals and licences required for their operations.

Depending on the industry, these may include:

• GST registration.
• Shops and Establishments registration.
• Factory licences.
• Pollution control approvals.
• FSSAI licences.
• Import Export Code.
• Labour law registrations.
• Industry-specific operating licences.
• Environmental and safety approvals.

The buyer should verify the validity, conditions and transferability of these permissions.

Some licences may not automatically transfer following an acquisition and may require fresh applications, prior approval or notification to the relevant authority.

Tax Due Diligence Before a Business Acquisition

Tax exposure is an important component of corporate due diligence because historical tax liabilities may affect the target company’s financial position even after ownership changes.

A buyer should examine the target’s tax records, filing history, pending assessments and disputed demands.

Important Tax Due Diligence Checks

Income Tax Returns

Review income tax returns for previous years and compare reported income with audited financial statements.

Examine assessment orders, reassessment proceedings, notices, appeals and outstanding tax demands.

GST Filings and Reconciliations

Verify GST registrations, returns, tax payments, input tax credit claims and reconciliations between books and GST records.

Identify any outstanding GST notices, demands, disputes or potential input tax credit reversals.

TDS Compliance

Review tax deducted at source, deposits, quarterly returns and relevant certificates.

Identify delayed deductions, short deductions, unpaid amounts and other compliance gaps.

Transfer Pricing Exposure

Where the target company has international or qualifying domestic related-party transactions, examine its transfer pricing documentation, benchmarking reports and accountant’s reports.

Tax Incentives and Benefits

Review tax exemptions, deductions, incentives and other benefits claimed by the target business.

Check whether the conditions attached to those benefits have been satisfied and whether the acquisition could affect their continued availability.

Pending Tax Disputes

Prepare a schedule of ongoing assessments, appeals, notices and tax demands.

Estimate the potential financial exposure and consider whether specific contractual protections are required.

A detailed tax review helps buyers understand historical tax risks and evaluate the financial implications of the proposed acquisition structure.

Commercial and Operational Due Diligence

Financial and legal reviews alone may not reveal whether the acquired business can maintain its market position and operate successfully after the transaction.

Commercial and operational due diligence examines how the business actually generates revenue, serves customers and manages its day-to-day activities.

Evaluate the Target’s Business Model

Understand:

• Main products and services.
• Revenue generation methods.
• Pricing strategy.
• Distribution channels.
• Major cost drivers.
• Business scalability.
• Competitive advantages.

The buyer should assess whether the existing business model is sustainable and compatible with its acquisition objectives.

Review Market Position and Competitors

Examine the target’s market share, customer demand, competitive landscape and industry trends.

A business may have strong historical revenue but operate in a market experiencing declining demand or increasing competition.

Examine Customer and Supplier Relationships

Review customer retention, contract terms, concentration risks and supplier dependencies.

A company that generates a significant portion of revenue from one or two customers may face substantial risk if those relationships end after the acquisition.

Assess Employees and Management Capabilities

Important considerations include:

• Key management personnel.
• Employment agreements.
• Salary and benefit obligations.
• Employee retention.
• Pending labour disputes.
• Incentive and ESOP arrangements.
• Promoter or founder dependency.

The buyer should understand whether important employees are likely to remain after the transaction and whether additional recruitment or restructuring may be required.

Review Technology and Business Processes

For businesses dependent on technology or digital infrastructure, the review should include:

• Accounting and ERP systems.
• Customer relationship management systems.
• Software licences.
• Data security practices.
• Cybersecurity controls.
• Backup and disaster recovery arrangements.
• Data protection policies.
• Third-party technology dependencies.

Operational weaknesses or technology risks can increase integration costs and affect the expected value of the acquisition.

Common Red Flags During Business Acquisition Due Diligence

A company acquisition checklist should help buyers identify issues that could affect the transaction price, legal position or future operations.

Some common warning signs include:

Not every red flag necessarily means that the acquisition should be abandoned. However, each issue should be investigated, quantified where possible and assessed for its impact on the proposed deal.

How Do Due Diligence Findings Affect Business Acquisition Decisions?

Due diligence findings should influence the acquisition strategy rather than simply appear in a final report.

The buyer must determine whether identified risks can be resolved, priced into the transaction or protected through appropriate contractual arrangements.

Reassess the Proposed Acquisition Price

If the review identifies lower sustainable earnings, higher debt or additional liabilities, the buyer may need to revise the proposed valuation.

For example, a company may report EBITDA of ₹5 crore, but the review identifies ₹80 lakh of non-recurring income and additional operating expenses that were not included in the seller’s calculations.

The buyer may need to reassess the sustainable earnings figure before finalising the purchase price.

Negotiate Representations and Warranties

Representations and warranties are contractual statements made by the seller about the business.

They may cover:

• Accuracy of financial information.
• Ownership of shares and assets.
• Compliance with applicable laws.
• Tax filings and liabilities.
• Pending litigation.
• Material commercial contracts.
• Intellectual property ownership.

Appropriate warranties help establish the seller’s contractual responsibility for specified matters, subject to the negotiated terms and limitations.

Consider Specific Indemnities

If due diligence identifies a known exposure, the buyer may negotiate a specific indemnity to address the relevant risk.

For example, a seller may agree to indemnify the buyer against a specified historical tax demand, subject to the agreed contractual conditions.

Structure Escrow or Deferred Payments

A portion of the purchase consideration may be held in escrow or paid later, depending on the transaction structure.

This can provide a mechanism for addressing specified post-closing claims, unresolved matters or agreed performance conditions.

Include Conditions Before Closing

Certain approvals, consents and corrective actions may be included as conditions precedent to completion.

These could involve:

• Regulatory approvals.
• Lender consent.
• Customer or supplier consent.
• Release of asset charges.
• Resolution of specific ownership issues.
• Completion of required corporate actions.

Reconsider the Acquisition

If major risks cannot be quantified or addressed adequately, the buyer may renegotiate the deal, restructure the transaction or decide not to proceed.

The objective of due diligence is not to justify completing every acquisition. It is to help the buyer make a decision based on verified information.

Why Professional Financial and Legal Due Diligence Matters

A business acquisition involves several areas of expertise. Financial records, tax filings, legal contracts, ownership documents and operational processes need to be reviewed together to understand the target’s overall risk profile.

Professional support can help buyers approach this process systematically.

Independent Verification of Information

Professional advisers examine supporting records instead of relying only on information provided in management presentations or seller discussions.

Better Identification of Financial and Legal Risks

A structured review helps identify undisclosed liabilities, reporting inconsistencies, contractual restrictions and potential compliance issues.

Improved Transaction Transparency

Documented findings provide buyers with a clearer picture of the target company’s financial position, legal standing and operational condition.

Better Negotiation Support

Financial and tax findings can help buyers evaluate pricing assumptions, while legal findings can support negotiations around warranties, indemnities, escrow and conditions precedent.

More Structured Acquisition Planning

A comprehensive review can help buyers understand the financial and operational requirements of integrating the acquired business.
