A set of audited financial statements tells an investor what the business reported. It does not tell the investor whether those profits will recur, whether the cash is really there, or which obligations sit outside the balance sheet. Financial due diligence (FDD) is the exercise that closes that gap before capital is committed, whether in an acquisition, a private equity investment, a joint venture or a lender's credit decision.
This article sets out what a financial due diligence covers, how the process runs in practice in India, the areas where issues most often surface, and, through a worked example, how the findings travel from the report into the price and the share purchase agreement. It is written for promoters preparing for a transaction, investors and finance teams working on either side of a deal.
Key points at a glance
- Financial due diligence is an analysis of the business behind the numbers, not a re-audit of the financial statements.
- Its core workstreams are quality of earnings, net debt and debt-like items, net working capital, cash flow and contingent liabilities.
- Most findings end up in one of four places: the price, a debt-like deduction, the working capital mechanism or contractual protection (indemnity, escrow, conditions precedent).
- A buy-side review works for the investor; a vendor due diligence is commissioned by the seller to prepare for the sale.
- The usual review period is two to three financial years plus the latest interim period, analysed month by month where possible.
What is financial due diligence?
Financial due diligence is an independent review of a target's historical financial information, carried out to help a buyer or investor understand the sustainable earnings, cash generation and financial position of the business. The output is a report of findings, typically with quantified adjustments, rather than an opinion on whether the accounts are true and fair.
The difference from a statutory audit is one of purpose. An audit under the Companies Act, 2013 tests whether the financial statements comply with the applicable accounting framework. FDD asks different questions: what profit is repeatable, how much cash the business needs to run, and which liabilities a buyer would effectively be paying for. A company can have a clean audit report and still produce significant due diligence adjustments.
Types of due diligence and where financial DD fits
| Type | Main question | Typical output |
|---|---|---|
| Financial | What are the sustainable earnings, net debt and working capital? | Adjusted EBITDA, net debt schedule, working capital peg |
| Tax | What tax exposures (income tax, GST, TDS, transfer pricing) come with the entity? | Quantified exposures, indemnity items |
| Legal | Are title, contracts, licences and litigation in order? | Red-flag report, conditions precedent |
| Commercial | Is the market and business plan credible? | Market view, forecast challenge |
| Operational / IT / HR | Can the business run and scale after closing? | Integration and separation issues |
FDD sits at the centre because tax, legal and commercial findings usually need to be quantified, and that quantification is done in the financial model.
What a financial due diligence covers
Quality of earnings
Reported EBITDA is adjusted for non-recurring items, related party terms, accounting policy changes and provisioning, to arrive at a normalised figure on which valuation multiples are applied.
Net debt and debt-like items
Beyond bank borrowings, the review identifies items a buyer treats as debt: statutory dues in arrears, unpaid gratuity and leave encashment obligations, deferred consideration from past acquisitions, customer advances not backed by delivery capacity, overdue creditors, and lease liabilities where the valuation basis requires it.
Net working capital
Receivables, inventory and payables are analysed month by month to set a normal level of working capital (the "peg") that the business should be delivered with.
Cash flow and cash conversion
Profit is reconciled to operating cash flow and to bank statements to confirm that earnings convert into cash.
Contingent liabilities and compliance
Pending tax demands, GST mismatches, guarantees given, litigation and regulatory non-compliance are identified and, where possible, quantified.
How the due diligence process runs in practice
- Scoping: agree the review period, materiality, entities in scope and the specific concerns of the investor.
- Information request: a detailed list covering trial balances, ledgers, ageing reports, contracts, tax returns, board minutes and management accounts.
- Data room review and analysis: monthly trend analysis, reconciliations between management accounts, audited accounts, GST returns and bank statements.
- Management discussions: structured sessions with the finance team and business heads to understand the drivers behind each trend.
- Draft findings: quantified adjustments, red flags and open points shared with the investor and its legal and valuation advisers.
- Final report and SPA input: findings are translated into price adjustments, definitions of net debt and working capital, specific indemnities and conditions precedent.
Practical point: The quality of the information request response often sets the timeline. Where monthly management accounts do not reconcile to the audited trial balance, a significant part of the review is spent rebuilding that bridge before any real analysis can begin.
How findings change the price: a worked example
Consider an investor negotiating to acquire 100% of a manufacturing company at 8 times EBITDA. Management presents EBITDA of ₹25 crore for the last financial year. The due diligence produces the following findings:
- A one-time insurance claim of ₹2 crore was credited to other operating income.
- Rent for the factory owned by the promoter is paid at ₹0.5 crore a year against a market rent of ₹1.5 crore.
- Bank borrowings are ₹30 crore and cash is ₹6 crore.
- Provident fund and GST dues of ₹1.5 crore are overdue, and an unfunded gratuity liability of ₹2 crore is identified.
- Working capital at closing is expected to be ₹3 crore below the normal level.
| Step | Before DD (₹ crore) | After DD (₹ crore) |
|---|---|---|
| EBITDA | 25.0 | 25.0 − 2.0 − 1.0 = 22.0 |
| Enterprise value at 8x | 200.0 | 176.0 |
| Less: net debt (30 − 6) | (24.0) | (24.0) |
| Less: debt-like items (1.5 + 2.0) | – | (3.5) |
| Less: working capital shortfall | – | (3.0) |
| Equity value | 176.0 | 145.5 |
Adjustments of ₹3 crore to EBITDA, ₹3.5 crore of debt-like items and ₹3 crore of working capital reduce the equity value by ₹30.5 crore. The EBITDA adjustments carry the largest weight because they are multiplied by the valuation multiple; every ₹1 crore of unsustainable EBITDA removes ₹8 crore of value in this example.
Buy-side versus vendor due diligence
In a buy-side review the adviser works for the investor and focuses on risks to the investor. In a vendor due diligence, the seller commissions the review before going to market, identifies issues early, fixes what can be fixed and presents a consistent set of adjusted numbers to bidders. Buyers usually still perform a confirmatory review, but a good vendor report shortens the timeline and reduces late-stage price renegotiation.
Common red flags in Indian transactions
- Revenue in books not reconciling with GST returns (GSTR-1 and GSTR-3B) or with bank receipts.
- Large year-end sales followed by credit notes or returns in the first months of the next year.
- Unexplained cash credits, loans from unrelated parties or share capital from entities with limited means.
- Delayed payments to MSME suppliers, with tax consequences under Section 43B(h) of the Income-tax Act, 1961 (Section 37 of the Income-tax Act, 2025).
- Qualifications or adverse remarks in the auditor's report or CARO 2020 reporting that are not addressed.
- Promoter expenses and related party transactions that are not at market terms.
Frequently Asked Questions on Financial Due Diligence
What is financial due diligence?
It is a review of a target company's historical financial information to assess its sustainable earnings, net debt, working capital requirement and financial risks before an acquisition or investment.
How is financial due diligence different from a statutory audit?
An audit gives an opinion on whether the financial statements comply with the accounting framework. Financial due diligence analyses what the numbers mean for a transaction, such as how much profit is repeatable and which liabilities should reduce the price.
How long does a financial due diligence take?
For a mid-sized Indian company, the fieldwork typically takes three to six weeks, depending on scope, the number of entities and how quickly information is provided.
What period does financial due diligence cover?
Usually the last two or three financial years and the latest interim period, with monthly analysis of revenue, margins and working capital where data is available.
What are debt-like items in due diligence?
They are obligations that are not classified as borrowings but will require cash after closing, such as overdue statutory dues, unfunded employee benefits, deferred consideration and overdue creditors. They are usually deducted from enterprise value to arrive at equity value.
What is vendor due diligence?
It is a due diligence commissioned by the seller before a sale process, so that issues are identified and addressed early and bidders receive a consistent view of the business.
Conclusion
Financial due diligence is most useful when it is linked directly to the transaction documents. Each finding should end up somewhere: in the adjusted EBITDA, in the net debt definition, in the working capital mechanism or in a specific protection in the agreement. Findings that are only described in a report, and not reflected in price or terms, provide little protection after closing.
For sellers, the same logic suggests preparing early. Reconciling books with tax returns and bank records, formalising related party terms and clearing statutory arrears before a process begins reduces both the adjustments and the time spent defending them.
