How to Prepare for Investor Due Diligence (50-Point Checklist)

You've just received a term sheet from an investor. The excitement is real, but the hard part is only beginning. Between a signed term sheet and the actual wire transfer lies one of the most nerve-wracking stages of fundraising: due diligence. For Indian startups, this process can make or break a deal. And most founders underestimate the depth of scrutiny involved.

We've worked with dozens of early and growth-stage startups going through this, and one pattern is clear: the companies that close rounds fastest are the ones that are always investor-ready -- not just when a deal is on the table.

This 50-point checklist is organized by category so you know exactly what investors will ask for and how to prepare well in advance.

What Is Due Diligence and When Does It Happen?

Due diligence is the formal investigation an investor conducts after expressing intent to invest -- usually after a term sheet is signed. The goal is to verify every claim you've made about your business: legal standing, financial health, tax compliance, team, contracts, and intellectual property.

For seed-stage deals, due diligence might be relatively light -- incorporation documents and basic financials. For Series A and beyond? Expect a thorough, multi-week process involving the investor's legal counsel, chartered accountants, and sometimes domain specialists. It typically takes 30 to 60 days, but poor preparation can stretch it to 90+ days. Sometimes it kills the deal entirely.

The number one reason deals die after a term sheet isn't valuation disagreements. It's messy compliance and missing documents surfacing during due diligence.

1. Corporate and Legal Documents

This is the foundation. Investors need to confirm that your company is legally constituted, properly governed, and free of disputes.

1. Certificate of Incorporation issued by the Registrar of Companies (ROC)
2. Memorandum of Association (MOA) and Articles of Association (AOA), including all amendments
3. PAN and TAN registration certificates of the company
4. Board resolutions for all major decisions: allotment of shares, appointment of directors, opening bank accounts, borrowings
5. Minutes of Board Meetings and General Meetings for the past 3 years
6. Shareholder agreements (SHA) and any side letters
7. Share Subscription Agreements (SSA) from all previous rounds
8. List of all directors (current and former) with DIN numbers and appointment/resignation dates
9. Statutory registers: Register of Members, Register of Directors, Register of Charges
10. Pending or past litigation, including consumer complaints, arbitration proceedings, and regulatory notices

2. Financial Documents

Investors will dissect your financials to validate revenue claims, understand your burn rate, and assess financial discipline.

11. Audited financial statements for the past 3 financial years (Balance Sheet, P&L, Cash Flow)
12. Provisional or management financials for the current year-to-date
13. Monthly MIS reports for the last 12-18 months
14. Bank statements for all company accounts for the last 12 months
15. Cap table showing shareholding pattern with share class, number of shares, face value, and premium
16. Details of ESOPs: pool size, grants issued, vesting schedules, exercised options
17. Outstanding loans and borrowings with sanction letters and repayment schedules
18. Related-party transactions disclosure as per AS-18 or Ind AS 24
19. Revenue recognition policy and details of deferred revenue, if any
20. Accounts receivable and payable ageing reports

3. Tax Compliance

Tax compliance is a major area where Indian startups stumble. Late filings, missed TDS deposits, and unreconciled GST returns are extremely common, and investors view them as serious red flags.

21. Income tax returns filed for the past 3 assessment years along with computation of income
22. GST registration certificate and all GSTR-1, GSTR-3B, and annual returns (GSTR-9)
23. GST reconciliation between books, GSTR-1, GSTR-3B, and GSTR-2A/2B
24. TDS returns (Form 24Q, 26Q, 27Q) filed for the past 2 years
25. TDS certificates (Form 16, 16A, 16B) issued to employees and vendors
26. Any pending tax demands, notices, or assessments under the Income Tax Act or GST Act
27. Advance tax payment challans for the current year
28. Section 80IAC certification (if availing startup tax exemption under the Startup India scheme)

A single unresolved GST notice or a TDS shortfall can hold up a funding round by weeks. Investors will insist on resolution or indemnity clauses before closing.

4. Regulatory and Statutory Compliance

This covers your company's standing with the Ministry of Corporate Affairs, labour law compliance, and foreign exchange regulations. That last one is critical if you're raising from foreign VCs or have a foreign holding structure.

29. Annual ROC filings: AOC-4 (financial statements), MGT-7 (annual return) for the past 3 years
30. DIR-3 KYC compliance for all directors
31. PF (Provident Fund) registration and monthly remittance challans
32. ESI registration (if applicable) and compliance records
33. Professional Tax registration and payment receipts
34. Shops and Establishments Act registration
35. FEMA compliance: FC-GPR filings for every foreign investment received, FLA returns filed with RBI
36. DPIIT recognition certificate (for Startup India benefits)
37. Sector-specific licenses: RBI registration (if fintech/NBFC), IRDAI (if insurtech), FSSAI (if food-related), etc.

5. Intellectual Property and Contracts

For tech startups, IP ownership is a core part of the valuation story. Investors need to confirm that the company, not the founders or a third-party vendor, owns all critical IP.

38. Trademark registrations and applications (brand name, logo, product names)
39. Patent filings, if any, along with status and jurisdictions
40. Domain name ownership records
41. IP assignment agreements from founders and contractors to the company
42. Employment agreements with IP assignment and non-compete clauses for all key employees
43. Vendor and contractor agreements, especially for outsourced development work
44. Customer contracts: template agreements, top 10 customer contracts, SLAs
45. NDA and confidentiality agreements with partners, vendors, and employees

6. Operational and Team Documents

Investors also evaluate the people behind the company. They want to understand your organizational strength, key-person dependencies, and HR practices.

46. Organizational chart with reporting structure
47. Full employee list with designation, date of joining, CTC, and employment type (full-time, contract, freelance)
48. Founders' CVs and background verification summaries
49. Key management personnel (KMP) details and succession plan, if any
50. Employee stock option plan (ESOP) policy document and grant letters

Common Red Flags Investors Look For

Knowing what raises red flags is just as important as having the right documents. Here are the issues that most commonly slow down or kill a deal:

• Gaps in ROC filings: Missing annual returns or financial statement filings with the MCA signal poor governance.
• Unreconciled GST returns: Mismatches between GSTR-1, GSTR-3B, and books of accounts raise questions about revenue accuracy.
• Late or missing TDS deposits: Indicates cash flow stress and disregard for statutory obligations.
• Related-party transactions without board approval: Any transactions with founders, family members, or associated entities without proper disclosures will be flagged.
• IP not assigned to the company: If the core product IP sits with a founder personally or with a development agency, it is a deal-breaker.
• Cap table inconsistencies: Share numbers that do not reconcile between ROC records, shareholder agreements, and internal trackers.
• Pending litigation not disclosed: Undisclosed lawsuits or regulatory actions destroy trust instantly.
• No employment agreements: Especially for key engineers and CXOs, this creates legal risk around IP ownership and non-compete.

How to Organize Your Data Room

A well-organized virtual data room (VDR) communicates professionalism and accelerates the due diligence timeline. Here is how to structure it:

Recommended Folder Structure

1. Corporate and Legal (incorporation docs, board resolutions, shareholder agreements)
2. Financial (audited statements, MIS, bank statements, cap table)
3. Tax (IT returns, GST returns, TDS filings, tax certificates)
4. Regulatory (ROC filings, PF/ESI records, FEMA compliance, licenses)
5. IP and Contracts (trademarks, patents, customer and vendor agreements)
6. Team and Operations (org chart, employee list, ESOP documents)
7. Product and Business (pitch deck, product roadmap, key metrics dashboard)

Use a secure cloud-based platform with granular access controls. Name every file clearly with dates and version numbers. Maintain an index document at the root level mapping each checklist item to its corresponding file.

Best Practices

• Keep all documents in PDF format where possible for consistency.
• Update documents quarterly, not just before a fundraise.
• Assign a single owner (typically the CFO, Head of Finance, or a senior CA) responsible for data room maintenance.
• Run a mock due diligence internally at least once a year to identify gaps before investors do.
