Due Diligence Checklist for Buying a Business in India

Due diligence is the process of verifying everything the seller has told you—and discovering what they haven't. Skip it at your peril.

Why Due Diligence Matters in India

The Indian SMB market has unique characteristics that make thorough due diligence essential:

• Cash-based transactions may not appear in official records
• Family businesses often have informal arrangements
• Compliance gaps are common and can become your liability
• Property titles can be complex

Three Checklist Items That Deserve Special Attention

Most of the checklist above is mechanical — request the document, verify it exists. These three items require judgment, not just verification, and are where Indian SMB deals most often go wrong.

GST compliance. Don't just confirm returns were filed — check the GST portal directly for the business's compliance status and any pending notices or demands. Request GSTR-1 and GSTR-3B for at least 24 months and compare GSTR-1 (outward supplies) against actual sales records, not just the summary numbers. Check input tax credit claims against purchase invoices. Also verify that major vendors and customers are themselves GST-compliant — their non-compliance can affect the business you're buying. Any GST litigation or pending demand should be resolved or escrowed before closing, not waved through on a promise.

Undocumented cash transactions. Many Indian small businesses have a cash component that doesn't show in official records — this is common enough that you need a plan for it rather than treating it as disqualifying. Sellers will often share "real" numbers verbally; verify what you can through physical footfall, inventory turnover, utility bills, and staff conversations, then discount the rest heavily. If a seller claims ₹50 lakh in unverifiable cash revenue, value it at ₹25-30 lakh at most — you can't confirm it and won't have recourse later if it doesn't materialize. Structuring part of the price as an earnout tied to actual post-acquisition performance is often the cleanest way to handle this rather than paying full value upfront for numbers you can't check.

Customer concentration. If one customer represents more than 20-25% of revenue, you are buying a dependency, not a business. Get a customer-wise revenue breakdown for 3 years, identify the top 10 accounts, and understand contract terms and renewal history for each. High concentration isn't automatically a dealbreaker, but it should materially affect valuation and deal structure — talk to the major customers directly before closing where possible, and consider earnouts tied to retention rather than paying full price for revenue that could walk out the door with the seller.

Red Flags to Watch For

🚩 Financial Red Flags

• Revenue that doesn't match GST returns
• Unusual related-party transactions
• Sudden improvement in recent financials
• Missing or inconsistent records

🚩 Legal Red Flags

• Pending litigation not disclosed
• Unclear property titles
• Missing regulatory approvals
• Restrictive contract clauses

🚩 Operational Red Flags

• Key employees planning to leave
• Customer concentration >30% in one account
• Supplier dependencies
• Deferred maintenance

Creating Your Due Diligence Team

For acquisitions above ₹50 lakhs, consider:

Timeline and Process

Week 1-2: Document collection and preliminary review
Week 3-4: Detailed analysis and site visits
Week 5-6: Expert consultations and issue resolution
Week 7-8: Final report and negotiation of findings

After Due Diligence

Your findings will typically result in one of three outcomes:

1. Proceed as planned (clean diligence)
2. Renegotiate terms (manageable issues)
3. Walk away (deal-breaker issues)

Never feel pressured to proceed if due diligence reveals serious concerns. Walking away is better than buying problems.
