Buyer Guide — India 2026

Due Diligence Guide for Buying a Business in India

A workstream-by-workstream guide covering every check a buyer should run before completing an acquisition — financial, tax, legal, commercial, operational, and India-specific compliance.

Quick Answer

Due diligence is the process by which a buyer verifies a target company's financials, tax compliance, legal ownership, contracts, licences, liabilities, customer concentration, operations and promoter dependence before completing an acquisition. In Indian SME transactions, the most important checks include normalised EBITDA, GST and ITR reconciliation, MCA filings, related-party transactions, statutory dues, customer concentration, title to shares, change-of-control clauses and promoter transition risk.

You have signed a Letter of Intent (LOI). The seller has agreed exclusivity. Now the real work begins.

The Information Memorandum was the seller's best case. The management meeting gave you the seller's story. Due diligence is where you test both against evidence — documents, third-party searches, financial analysis, and direct enquiry.

Most deal risk surfaces during due diligence. Buyers who skip it, rush it, or delegate it without oversight tend to discover problems after closing — when the options available are expensive and limited.

Five workstreams. One objective: verify everything before you sign.

Due diligence runs across five parallel workstreams, each led by a different advisor, each producing findings that feed into the others. Understanding who leads what — and why — is the first step to running the process well.

Workstream Led By Key Objective
Financial DD CA / Transaction Advisor Verify earnings quality, cash flows, working capital and liabilities
Tax DD CA / Tax Advisor Identify GST, income tax, TDS and contingent tax exposures
Legal DD Lawyer / CS Verify ownership, contracts, litigation, licences and compliance
Commercial DD Buyer / M&A Advisor Test customers, revenue durability, market position and competition
Operational DD Buyer / Sector Specialist Assess people, processes, systems, capacity and founder dependence

Realistic timeline

The timeline below reflects a reasonably organised seller with substantially complete documentation. Sellers with incomplete records, multiple locations, or pending regulatory matters will typically extend each phase.

Phase Typical Duration What Happens
LOI signed / exclusivity agreed Day 0 Starting gun for formal diligence. Exclusivity period typically 45–90 days.
Document request issued Days 1–3 Full document request list sent. Data room or shared folder set up.
Initial document review Weeks 1–2 Financial statements, tax returns, corporate documents reviewed. First issues log drafted.
Deep-dive analysis Weeks 3–6 Financial, tax, and legal DD running simultaneously. Management Q&A sessions.
Commercial / operational DD Weeks 4–7 Customer and supplier interviews, site visit, key employee assessments.
India-specific checks Weeks 3–6 MCA searches, CIBIL checks, GST portal verification, EPFO, sector licences.
DD reports issued Weeks 7–9 Each workstream delivers findings. Issues log consolidated.
Price / terms renegotiation Weeks 8–10 Findings translated into price adjustments, indemnities, conditions precedent.
SPA negotiation Weeks 9–14 Definitive agreement drafted and negotiated, informed by DD findings.

Getting organised — the steps that determine how well the rest of the process runs

Secure exclusivity first

Formal due diligence is expensive and time-consuming. Before engaging any advisor, ensure your LOI includes a defined exclusivity period — commonly 45 to 90 days in Indian SME transactions — during which the seller agrees not to engage other buyers. Without exclusivity, you bear the full cost of diligence while the seller runs a parallel process.

Assemble your team before Day 1

You will need, at minimum: a CA with M&A experience for financial and tax DD; a corporate lawyer for legal DD and SPA drafting; and a Company Secretary for ROC searches and compliance verification. For sector-specific businesses — pharma, food processing, manufacturing with environmental obligations, technology — also add a sector specialist.

📌 Important distinction

The CA leading due diligence is not your regular statutory auditor. You need someone who has conducted acquisition diligence before and understands normalised earnings analysis, quality-of-earnings reviews, and contingent liability assessment.

Set up structured document collection

Do not let documents arrive informally over email or WhatsApp. Agree on a document request list and a delivery mechanism — a virtual data room (VDR) or a well-organised shared folder with version control — before diligence begins. Agree a delivery schedule and track against it. Selective delays in document delivery are informative in themselves.

If you sourced this deal through MergerDomo, the platform's staged disclosure process already structures document delivery — financials and operational data are released only after mutual EOI approval and NDA signing, giving you a clean, documented starting point for formal diligence. For deals sourced elsewhere, replicate this discipline manually: agree the request list, the delivery channel, and the timeline before Day 1. Download the Due Diligence Checklist →

CCI merger control — check thresholds early

Most Indian SME acquisitions fall well below Competition Commission of India (CCI) notification thresholds. As of the time of writing, the thresholds require combined assets exceeding ₹2,000 crore or combined turnover exceeding ₹6,000 crore — a deal value threshold of ₹2,000 crore was also introduced in 2023 for transactions with significant Indian nexus. Always verify current thresholds with your legal advisor before any transaction.

Buyer Action

Do not start formal diligence until exclusivity is confirmed in writing. Confirm your CA, lawyer, and CS are briefed and available for the full diligence period before Day 1 — not after the document request goes out.

Verifying the real economic performance of the business — not just what the accounts say

Financial DD is not the same as reading the audited accounts. An auditor verifies that accounts present a true and fair view under accounting standards. Your job is different: to understand what the business will actually earn under your ownership.

Quality of earnings

Examine how much reported revenue and profit is recurring, reliable, and genuinely earned. Are revenues recognised at point of delivery or upfront? Are there related-party sales at above-market prices inflating the reported top line? Are there large one-off items — asset sales, insurance receipts — that boost profit in specific years only?

Normalised EBITDA — the real negotiating number

Most Indian SME valuations are based on a multiple of EBITDA. The seller will present a "normalised" figure with add-backs. Some are legitimate: a promoter drawing well above a market-rate salary is a real normalisation. A genuine one-off legal cost is a reasonable adjustment.

"The normalised EBITDA the seller presents and the figure your CA arrives at independently are frequently different. That gap is where a significant portion of price negotiation in Indian SME transactions actually occurs."

Watch for: add-backs described as "exceptional" that appear across multiple years; personal expenses run through the business; related-party costs at above-market rates being added back; and depreciation normalisation that substantially inflates the number. Every add-back should be individually justified with documentary evidence.

Working capital analysis

Sellers sometimes run down working capital ahead of a sale — collecting receivables aggressively, stretching payables, drawing down inventory — to maximise cash on the balance sheet at closing. If working capital at closing is below the normalised level, the buyer effectively overpays. Negotiate a working capital peg — a target level at closing with a price adjustment mechanism — before signing the SPA.

Debt and contingent liabilities

Map every liability: term loans, working capital facilities, equipment finance, deferred payment obligations, informal borrowings from family members or associates, and guarantees the company has given for third parties. In a share sale, the buyer inherits all of this. Cross-check the debt schedule against bank statements and the balance sheet.

Related-party transactions

Map every related-party transaction and assess whether pricing is commercial. Related-party revenues that will disappear on Day 1 are not part of the business you are buying — they must not be included in the normalised earnings base on which you are valuing the company.

Triangulation — the most important technique

Cross-check reported revenue and profit against independent data sources. Unexplained gaps between these sources are not bookkeeping errors until proven otherwise:

  • Reported revenue vs GSTR-1 filings
  • Tax paid vs reported profit (adjusted for timing)
  • Bank statement credits vs revenue figures
  • Payroll costs on P&L vs PF contribution records
  • Purchase volumes vs production output
  • Debtor ageing vs revenue recognition timing
Buyer Action

Do not accept the seller's normalised EBITDA figure without independent add-back verification. Triangulate revenue against GST returns and bank statements before forming any view on earnings quality.

Identifying what the business actually owes — including what hasn't crystallised yet

Tax DD is a distinct workstream from financial DD. Its purpose is to identify contingent tax liabilities — taxes that are owed, disputed, or potentially payable — not fully reflected in the audited accounts.

ITR reconciliation

Reconcile Income Tax Returns filed for the last three to five years against the audited financial statements. Material unexplained differences — reported profit significantly higher in the audited accounts than declared in the ITR, or vice versa — require full explanation before proceeding.

GST compliance

Review GSTR-1 (outward supply returns) and GSTR-3B (summary returns) for the last 24 to 36 months. Check whether GSTR-1 figures reconcile with reported revenue. Look for mismatches in Input Tax Credit claimed versus what counterparties have filed. Confirm the absence of outstanding notices, demand orders, or audit proceedings on the GST portal.

TDS compliance

Verify that Tax Deducted at Source has been correctly deducted on applicable payments — salary, contractor payments, rent, professional fees — and deposited within required timelines. Outstanding TDS defaults attract interest and penalties and constitute a contingent liability that transfers with the shares.

Pending assessments and demand notices

Review the company's tax correspondence and check the TRACES and ITD portals for outstanding demands. Any pending demand not fully provided for in the accounts should be quantified — and a specific indemnity negotiated in the SPA to cover any crystallised liability post-closing.

Labour codes compliance

India's four Labour Codes — consolidating 29 central labour laws — are in various stages of state-level notification. Verify compliance with applicable provisions around wages, social security (PF, ESIC, gratuity), occupational safety, and industrial relations. Gaps in historical compliance create contingent liabilities that transfer in a share sale. The specific obligations depend on sector, headcount, and states of operation; verify with a labour law specialist where material.

Transfer pricing

If the company has transactions with associated enterprises and those transactions exceed applicable thresholds under the Income Tax Act, verify that transfer pricing documentation has been maintained and that no adjustments are pending or under scrutiny.

Buyer Action

Request a complete list of all pending income tax assessments, GST notices, and TDS defaults from the seller's CA. Cross-check independently via the ITD portal, TRACES, and GST portal. Negotiate specific indemnities for every material identified exposure.

Verifying ownership, contracts, licences, litigation — and the legal risks you cannot see from a P&L

Title to shares and beneficial ownership

In a share purchase, verify that the seller owns the shares they are selling, free of encumbrances. Cross-check the shareholding against the Register of Members and the most recent ROC annual return. Check for pledged shares on the MCA charge register — any pledge must be released before closing. Also verify the Significant Beneficial Owner (SBO) register under the Companies Act 2013 is maintained and reconciles with the actual ownership structure. Undisclosed beneficial ownership layers can create post-closing governance complications.

Corporate records and MCA searches

Pull the company's filing history from MCA21. Review the MOA/AOA, board resolutions authorising material transactions, all filed annual returns, and the charge register. Look for unsatisfied charges on repaid loans, director disqualification history, and any show-cause notices or strike-off proceedings visible in the MCA history.

Material contracts — change-of-control clauses

Review all material customer, supplier, distribution, and licensing agreements for clauses that allow a counterparty to terminate or renegotiate on a change of ownership. These are particularly common in government contracts, franchise agreements, and technology licences. Where identified, assess materiality and whether consent should be obtained as a condition precedent to closing.

Employment, HR and labour compliance

Review employment agreements for key personnel — notice periods, non-compete clauses, garden leave provisions. Verify PF and ESIC compliance through the respective portals. Review any ESOP or bonus obligations the buyer will inherit. Assess key person risk: which employees are essential and what is their likelihood of staying post-acquisition?

Intellectual property

Identify all IP — trademarks, patents, domain names, software, trade secrets. For each, verify that it is registered in the company's name — not the promoter's name, not a related entity. Trademarks held personally by the Indian promoter are a common finding and need to be transferred before or at closing, with the tax and stamp duty implications of that transfer assessed in advance.

Litigation

Do not rely solely on the seller's disclosed list. Run independent searches through district court portals, the NCLT, the DRT where applicable, and consumer dispute redressal commission databases. Assess each proceeding for quantum of potential liability, likelihood of adverse outcome, and timeline to resolution.

Regulatory licences and approvals

List every licence, registration, and approval the business needs to operate. Verify each is current and in the company's name — not the promoter's. Common areas of concern:

  • Factory licences & pollution control consents
  • FSSAI registrations / licences
  • Drug manufacturing licences
  • Import/Export Code (IEC)
  • BIS certifications and quality approvals
  • Government tender qualification criteria
  • Environmental clearances
  • RBI / SEBI licences where applicable

Real estate and property

If the business occupies owned property: verify title deeds, obtain encumbrance certificates, confirm the property is in the company's name, and review all lease or rental agreements. Check municipal approvals and building plan sanctions. For leased premises, confirm the lease survives a change of ownership and assess renewal risk. Stamp duty on property transfer varies significantly by state — model this into total acquisition cost early.

Insurance

Review current coverage — property, product liability, professional indemnity, and key-person policies. Confirm policies survive a change of ownership and identify any material uninsured risks.

DPDP Act — data protection

For businesses with significant customer data — e-commerce, fintech, healthcare, consumer services — assess compliance with India's Digital Personal Data Protection Act, 2023. Verify consent mechanisms are in place and engage a lawyer with data protection experience for any business where personal data is a material asset or operational input.

Buyer Action

Run independent litigation searches — do not rely solely on the seller's disclosure. Verify every material licence is in the company's name and transferable. Check the SBO register is complete and reconciles with the actual cap table.

Testing whether the revenue is real, durable, and survivable without the founder

Customer analysis

Work through revenue by customer for the last three years. What percentage comes from the top five and top ten customers? Has concentration increased or decreased? Have significant customers been lost, and why? For the largest customers, is the relationship documented in a formal contract — or is it personal to the founder?

Supplier and operational dependency

Map the top ten suppliers by spend. For each: single-source risk, pricing stability, geographic concentration, and contractual arrangements. For businesses dependent on imported inputs, assess exchange rate and supply chain risk.

Key person and promoter dependency

This is the most consistently underestimated risk in Indian SME diligence. In many founder-led businesses, critical knowledge, relationships, and decision-making authority sit entirely with the founder. If this is the case, structure the deal accordingly — longer transition period with specific deliverables, retention packages for key employees, and contractual obligations on the founder to effect customer introductions.

"Revenue that is personal to the promoter is not business value — it is relationship value that evaporates on exit. The buyer's job is to quantify that risk before signing, not discover it after closing."

Team, HR, and culture

Review the org chart against reality. Who actually makes decisions? What are the notice periods for critical staff, and are they enforceable? Identify the highest-risk employees from a retention perspective: salespeople who own customer relationships, technical specialists with non-replicable skills, and operational managers who run day-to-day processes.

Operational processes, IT systems, and cybersecurity

Assess whether the business has documented processes for critical functions — or whether knowledge is entirely in the heads of individuals. Review accounting and ERP systems: are they standard commercially available platforms, or proprietary systems with limited portability? For businesses where customer or operational data is a material asset, also conduct basic cybersecurity diligence — assess whether data is adequately secured, whether there have been incidents, whether access controls are in place, and whether systems carry unpatched vulnerabilities that create post-acquisition exposure.

Buyer Action

Map every significant customer relationship to a specific individual. If that individual is the founder, build a specific transition plan into the deal structure before signing. Do not assume customer relationships will survive a change of ownership without active management.

The checks that experienced Indian acquirers run — and first-time buyers most commonly miss

These checks are specific to the Indian regulatory environment and are not covered in generic due diligence frameworks.

1
MCA21 portal searches

Run searches on the Ministry of Corporate Affairs portal (mca.gov.in) for: the charge register (verify all charges are satisfied for repaid loans); director history (check for disqualifications under Section 164 of the Companies Act 2013); filing history (gaps and delays signal compliance culture); and any show-cause notices or strike-off proceedings. Do not rely on the seller to surface these — run them independently.

2
CIBIL and credit checks

Obtain a CIBIL credit report for the company and — with the promoter's consent — for the promoter personally. This surfaces defaults, settlements, or adverse credit events that do not appear elsewhere. For businesses with significant borrowings, also review loan account statements to confirm regular repayment and no default classification.

3
GST portal verification

Confirm active GSTIN status. Cross-check e-way bill volumes against reported logistics activity for goods-heavy businesses. Verify HSN/SAC codes are consistent with the nature of the business. For multi-state businesses, verify each GST registration separately.

4
EPFO compliance check

Verify that the company's EPFO code is active and that employee count registered with EPFO is consistent with the payroll figure in financial statements. Gaps between payroll headcount and EPFO headcount are common in Indian SMEs and may indicate informal employment arrangements that carry their own legal risk.

5
Sector-specific licence transferability

Some licences are granted to a specific individual (typically the promoter) as a "qualified person" or "person in charge." In these cases, the licence does not automatically continue when shares change hands. This is particularly relevant in pharmaceutical manufacturing (drug licences), certain financial services businesses, and businesses holding specific government approvals. Verify the position with a specialist before assuming continuity.

6
Bank NOC and personal guarantee release

Personal guarantees given by the promoter on company borrowings do not automatically transfer in a share sale. Confirm as a condition of closing that the bank releases the promoter's guarantee (with the buyer providing replacement security), or that a clear arrangement exists. This is one of the most common sources of post-closing disputes in Indian SME transactions and must be resolved before — not after — signing.

Buyer Action

Run MCA, CIBIL, GST portal, and EPFO checks independently — do not rely on seller representations for any of these. Confirm bank NOC and guarantee release as a formal condition precedent to closing, not an informal understanding.

Most findings are not deal-killers — they are repricing or protection events

The skill of a well-advised buyer is translating DD findings into appropriate deal terms, not simply walking away from every imperfection.

Price adjustments

Financial DD findings that reduce normalised EBITDA flow through to a proportional reduction in the purchase price. Identified liabilities result in either a direct price deduction or the seller's commitment to resolve the liability before closing.

Specific indemnities

Where DD surfaces a specific identified risk that cannot be quantified with certainty — a pending assessment, a disputed contract — the appropriate protection is a specific indemnity in the SPA: a direct contractual obligation on the seller to reimburse the buyer for any loss arising from that specific matter. Specific indemnities are typically uncapped and more powerful than general warranty coverage.

Escrow and holdback

For residual risks that DD could not fully rule out, buyer protection comes through general representations and warranties backed by escrow or holdback. In some Indian SME transactions, a portion of the purchase consideration is held in escrow post-closing — commonly 12 to 24 months — to provide accessible recourse if a warranty claim arises. A seller confident in the accuracy of their disclosures should be willing to accept reasonable escrow terms. Strong resistance to any post-closing protection mechanism is itself a signal worth noting.

Conditions precedent

Material DD findings sometimes need to be resolved before closing — not just indemnified against. Common examples: obtaining consent from a key customer where a change-of-control provision has been identified; transferring IP from the promoter's name to the company; obtaining bank NOC for guarantee release; resolving a specific regulatory compliance gap.

Walk-away thresholds

Some findings justify exiting the transaction. These typically include: systematic financial misrepresentation that cannot be reconciled across sources; undisclosed material litigation that fundamentally changes the risk profile; licences or contracts essential to the business that cannot be transferred; or fraud or intentional concealment that destroys confidence in the seller's disclosures. The standard for walking away is not that problems exist — every business has problems — but that the problems are so material, or the seller's conduct so concerning, that the risk cannot be adequately priced or protected against.

Buyer Action

Before any findings discussion with the seller, consolidate all workstream issues into a single ranked issues log — categorised as price adjustment, specific indemnity, condition precedent, or walk-away. Negotiate the package, not individual issues in isolation.

Signals — across all workstreams — that warrant additional investigation or reconsideration of the transaction

Financial

  • Irreconcilable financials.Financials, GST returns, and bank statements cannot be reconciled. This is either very poor accounting or deliberate misrepresentation. Neither is acceptable.
  • A creative list of add-backs.Add-backs that together eliminate most of the reported cost base. If they cannot each be individually justified with documentary evidence, challenge the normalised figure entirely.
  • Revenue concentration in related-party sales.Revenue from entities controlled by the promoter that will not continue post-acquisition is not part of the business being sold.
  • Working capital below the operational norm.A business that appears to have been stripped of cash, receivables, or inventory immediately before diligence.

Tax

  • Material gaps between ITR and audited accounts.Unexplained differences across multiple years require full reconciliation before proceeding.
  • Multiple outstanding GST notices.A pattern of non-compliance, not a one-off issue.
  • TDS defaults across several years.Systematic non-compliance with deduction and deposit obligations indicates a company that does not take statutory dues seriously.

Legal

  • Key IP or licences held personally by the promoter.The business cannot operate post-acquisition until these are transferred — transfer takes time, has tax implications, and is not guaranteed to be straightforward.
  • Change-of-control clauses in material customer contracts.If exercised, these could remove a significant portion of revenue on Day 1 of your ownership.
  • Litigation surfaced through independent search that was not disclosed.Omission of a material legal proceeding from the seller's disclosure is not a clerical error.

Commercial and operational

  • All significant relationships owned personally by the founder.Revenue that is personal to the promoter is relationship value — not business value. It evaporates on exit.
  • Revenue growing on paper with no order book evidence.Reported pipeline that does not convert, with no historical conversion rate to validate it.
  • No documented processes for any core business function.A business that stops when the founder steps back transfers poorly.

Conduct during diligence

  • Selective document delivery delays.Some documents arrive promptly, others are repeatedly deferred. The pattern is more informative than the delay itself.
  • Inconsistency between what the founder says and what documents show.A single inconsistency is worth questioning. A pattern is a deal signal.
  • Strong resistance to any post-closing protection.A seller confident in their disclosures has nothing to fear from reasonable escrow or indemnity terms.

Common questions about due diligence for Indian acquisitions
Most SME due diligence takes 6 to 10 weeks from when documents start arriving. Simple deals with well-organised sellers can complete in 4 to 6 weeks. Complex businesses or incomplete records can extend to 12 weeks or more.
The buyer pays for their own diligence advisors — CA, lawyer, CS, and any sector specialists. Budget for these costs before starting, not after. They are a non-negotiable part of the acquisition cost.
An audit verifies that financial statements present a true and fair view under accounting standards. Due diligence is forward-looking — its purpose is to inform a buyer about the real economic performance and risk profile of a business they are about to acquire.
Some preliminary financial review happens before the LOI. Formal structured diligence with a full document request and advisors generally commences after the LOI is signed and exclusivity is in place. Starting full diligence before the LOI exposes the buyer to cost risk if the deal does not proceed.
Treat sustained refusal or delay as a serious signal. A seller reluctant to open their records fully either has something to conceal or has not prepared for a sale. Escalate through your M&A advisor, invoke delivery obligations in the LOI, and reassess whether to continue.
