Financial model review services in India give a lender, an investor, a board or a valuer an independent view on a model before they rely on it. The review tests whether the arithmetic holds, whether the logic follows the signed documents, and whether Indian tax, Foreign Exchange Management Act, 1999 (FEMA) and sector rules sit correctly inside the numbers. Two changes have reset what a model must reflect: the Reserve Bank of India (RBI) Project Finance Directions, 2025, effective 01/10/2025, and the Income-tax Rules, 2026, effective 01/04/2026. This guide covers tiers, standards, report contents, timelines and provider selection.

### What does a financial model review service include?

A financial model review service is an independent examination of a financial model by someone who did not build it. It tests formula integrity and arithmetic, checks that assumptions are applied consistently, reconciles outputs to source documents and to tax or regulatory rules, and ends in an issue log and a written conclusion. Scope runs from a quick technical scan to a full cell-by-cell audit.

## Who commissions financial model review services in India?

Six parties commission a financial model review: lenders, investors, boards, acquirers, fund managers and valuers, and companies pricing shares for non-resident investors. Each needs a different conclusion from the same spreadsheet. The party carrying the risk usually pays for the review and sets the scope, so scope follows the buyer rather than the model.

Most provider pages speak to one generic investor. In practice the question changes with the commissioning party. A lender wants to know whether debt service holds under stress. An investor wants the projection to tie to the cap table and the latest management accounts. A valuer wants the discount rate, terminal value and fully diluted share count to survive challenge. Name the audience in the brief and the reviewer can scope to it.

**Table 1: Who commissions a model review and what each needs confirmed**

The party whose money or reputation depends on the numbers being right usually commissions the review, and that holds in India. If the company itself is the buyer and the goal is a clean model before diligence starts, the narrower fix list sits in our guide on [what to fix in a financial model before investors see it](https://treelife.in/finance/financial-model-validation-before-a-data-room/).

## How do a financial model review, audit and validation differ?

The labels overlap, so the engagement letter matters more than the title. A review tests structure and common errors. An audit inspects every formula and reconciles outputs. Validation, the term used for pre-diligence clean-up, tests fitness for a stated purpose. Ask which tests will run, on what evidence, and who signs the conclusion.

Search results for financial model audit India and for financial model review mix the two because providers use them interchangeably. The practical split is by depth. Published tier structures from global providers show the pattern.

**Table 2: Review tiers, depth and typical use**

TierWhat it testsTypical useTypical turnaround (estimate)Quick technical scanFormula consistency, error values, hardcoded inputs, broken linksTriage before deciding on deeper work1 to 2 daysComfort reviewKey logic, structure, selected reconciliations, scenario behaviourInvestor or board comfortAbout 1 weekFull auditCell-by-cell inspection, often with independent replicationLender condition precedent, bid or financial close2 to 3 weeksAssurance opinionSigned opinion letter, defined scope and limitations, named parties who may rely on itFinancial close, regulated reportingAgreed in the engagement letter

The turnaround ranges are estimates drawn from provider-published offers in 2026 and move with model size. Read them as relative effort, not a quote.

Method matters as much as tier. Reading formulas cell by cell finds the errors you thought to look for, while rebuilding the model independently from its inputs finds the ones you did not. A full audit that skips independent replication tests less than its label suggests.

Four facts decide the tier you need:

- The audience, and whether they asked for a signed letter

- The amount at stake relative to the complexity of the model

- The time left before the deadline

- Whether the model will be reissued after every investor comment

A scan bought when a lender needs a full audit wastes the fee. A full audit bought for an internal board paper wastes the quarter.

### Why does a second reviewer find what the builder missed?

The builder checks what they meant to build, and a reviewer checks what is on the sheet. Published spreadsheet research is older and global, but consistent. An industry review of client models, reported at the 2001 European Spreadsheet Risks Interest Group (EuSpRIG) conference, found major errors in 95% of them and poor design in 59% ([EuSpRIG, 2001](https://arxiv.org/pdf/0801.1514.pdf)). Raymond Panko’s summary of field audits counted 49 of 54 spreadsheets with significant errors, and all 30 project financing spreadsheets in a later exercise had at least one mistake ([The Register, 2006](https://www.theregister.com/2006/05/03/buggy_spreadsheet)). None of this is Indian data.

Reviewers who expect errors test more and catch more of the material ones ([Society of Actuaries, 2008](https://www.soa.org/4936a1/globalassets/assets/library/newsletters/compact/2008/january/com-2008-iss26-campbell.pdf)). That is the practical case for independence: the point is a different mindset, not a better modeller.

### How does the right depth change with funding stage?

Depth should follow the audience’s likely first question. A reasonable default:

- **Seed and angel:** a scan or short comfort review focused on runway, burn, the hiring plan and a three-statement flow that balances.

- **Series A:** a comfort review as the floor, with reconciliation to actuals and the cap table, since investors test unit economics and dilution first.

- **Series B and growth equity:** a full audit when the lead investor or a lender asks, plus statutory treatment review where non-resident money is involved.

- **Lender or buyout:** a full audit, and an assurance opinion where the lender requires one.

### When should a model be rebuilt instead of reviewed?

There are three routes: review, retrofit and rebuild. A review fixes a sound structure and logs the issues. A retrofit restructures a model whose logic is right but whose layout is hard to audit, keeping its history. If the structure itself is unsound, fixing it costs more than starting again, and a rebuild is usually the better recommendation. Four signs point to a rebuild:

- Inputs, calculations and outputs sit on the same sheets

- No integrity checks exist, and scenarios need manual edits

- Circular references or macros that nobody can explain

- Findings so dense that each fix creates two more

If one firm rebuilds the model, a different team should review it. Independence is the point of the exercise.

## Which standards should a financial model audit follow?

No Indian statute prescribes how to review a financial model, so the standard is a matter of contract. Reviewers use FAST for model structure, the ICAEW Financial Modelling Code for build principles, and, where a chartered accountant signs a report on projections, ICAI SAE 3400. Name the standard in the engagement letter.

- **FAST (Flexible, Appropriate, Structured, Transparent):** a structuring standard for spreadsheet models, maintained by the FAST Standard Organisation ([ACT wiki](https://wiki.treasurers.org/wiki/FAST_Modelling_Standard)). It tells a reviewer whether a model is built to be inspected.

- **ICAEW Financial Modelling Code (first published 12/11/2018):** twenty principles for good spreadsheet practice. ICAEW states the Code is not meant for tick-box compliance ([ICAEW](https://www.icaew.com/technical/business/financial-management/financial-modelling-and-forecasting/getting-your-financial-models-right)).

- **ICAI SAE 3400, The Examination of Prospective Financial Information:** the standard for a chartered accountant’s engagement to examine and report on projections, effective for reports issued on or after 01/04/2007, with management remaining responsible for the projections ([ICAI](https://kb.icai.org/pdfs/PDFFile5b443eed9ae701.45264656.pdf)).

- **IPEV Guidelines:** endorsed by SEBI’s Master Circular for AIFs, dated 03/06/2026, for valuing unlisted securities held by AIFs.

A spreadsheet review is not an SAE 3400 engagement. If a lender or regulator asks for an assurance report on projections, confirm in writing that the engagement is structured and signed as one. If an investor only wants comfort that the model works, a lighter advisory review is the right product and costs less.

## What does a reviewer actually test in a financial model?

A reviewer runs ten tests, usually with a tool-assisted scan first and independent replication second: structure, formula consistency, hardcodes, integrity checks, time and flag logic, units and signs, circularity and macros, debt, tax and working capital schedules, the valuation layer, and scenario behaviour. Each test has a failure signature and a severity.

**Table 3: The ten tests, their method and what failure looks like**

Test areaHow it is testedWhat failure looks likeTypical severityStructure and flowTrace inputs to outputs; confirm inputs, calculations and outputs sit apartAn input typed on a calculation sheet, or stored in two placesMajorFormula consistency across the time axisCompare each row’s formula across every period using a tool that flags breaksA formula that changes mid-row after a manual overwriteCritical or majorHardcoded valuesScan for constants inside formulas and values pasted over formulasA growth rate typed inside a revenue formulaMajorIntegrity checksConfirm the balance sheet balances and cash ties in every period; try to make the checks failA balance check forced to show zeroCriticalTime and flag logicTest dates, start and end switches, timing flags and period lengthsThe funding or commissioning date moves but interest or depreciation does notMajorUnits, signs and currencyCheck units (₹ lakh, ₹ crore, thousands), sign conventions and conversion datesA crore figure read as lakh in a downstream sheetCriticalCircularity and macrosLocate circular references and macro code; run the model with them on and offInterest on average balance with unstable iteration; an undocumented macroMajorDebt, tax and working capital schedulesRe-perform interest, repayment, tax and working capital days independentlyInterest on closing balance where the loan agreement says averageMajorValuation layerRecompute the discount rate build-up, terminal value, equity bridge and share countNet debt or the diluted share count left out of the equity bridgeCriticalScenario and stress behaviourRun base, downside and boundary cases; confirm every output movesA scenario switch that changes revenue but not costMajor

Severity here reflects reviewer judgment, not a regulatory grade. The tool-assisted scan comes first. Scanners find unreferenced cells, hardcoded constants and inconsistent formulae and track every change between iterations, and some providers use a formula assessment report to estimate scope and price. Independent replication follows: the reviewer rebuilds the outputs from the inputs and treats any gap as a finding. Ask any provider which tool it uses and whether it tracks changes between versions. The founder-side fix list for the same ground is in our guide on [what to fix before investors see the model](https://treelife.in/finance/financial-model-validation-before-a-data-room/).

### How do review checks change by model type?

Standard tests apply to every model. The extra checks depend on what the model is for.

**Table 4: Extra checks by model type**

Model typeExtra checksRule or standard hookSubscription or SaaSDeferred revenue and revenue recognition, cohort and churn mechanics, ESOP expenseInd AS 115 and Ind AS 102NBFC or lending platformLoan book roll-forward, credit loss provisioning, capital adequacy, regulatory sensitivityInd AS 109 credit loss framework; RBI norms for the entityInfrastructure and project financeDebt sculpting, reserve accounts such as DSRA, DCCO and tenorRBI (Project Finance) Directions, 2025Capital-intensive manufacturingCapex timing, capacity ramp, working capital cycle, asset lifeAccounting policy for depreciation and useful lifeHolding company or groupConsolidation, intercompany eliminations, cross-holdings, related-party flowsGroup accounting policyAIF or fundDistribution waterfall, carry and clawback, NAV roll-forwardSEBI (AIF) Regulations, 2012, Regulation 23

The sector emphasis follows how these models are built and financed in practice. A reviewer who has not worked in your model type will run the ten tests and miss these.

## Which Indian rules must a financial model review reflect?

Four rule sets sit inside most Indian models: share valuation under Rule 57 of the Income-tax Rules, 2026, FEMA pricing under Rule 21 of the Non-debt Instruments Rules, 2019, SEBI’s valuation framework for AIFs under Regulation 23, and the RBI Project Finance Directions, 2025 for lender cases. A reviewer without Indian tax and regulatory depth tests none of them.

**Table 5: Indian rule sets a model review should reconcile**

### Which tax valuation rule does the model cite?

The Income-tax Act, 2025 came into force on 01/04/2026 and the Income-tax Rules, 2026 replaced the 1962 Rules. The fair market value rule formerly numbered 11UA now sits in Rule 57, with definitions in Rule 56 ([Income Tax Department](https://www.incometaxindia.gov.in/w/rule-57-4)). Models and valuation reports drafted before that date still cite Rule 11UA and sections of the 1961 Act.

Some Indian provider pages still list Rule 11UA as their compliance basis for modelling work, so a scope that cites it is a sign the provider has not updated. A reviewer checks three things: the purpose stated on the cover sheet maps to a provision in force, older section references are remapped, and the valuation method used suits that provision. The valuation rules themselves are covered in our guide on [how startup valuation works in India](https://treelife.in/startups/how-startup-valuation-works-in-india/).

### How does FEMA pricing change what the model must show?

Rule 21 of the FEM (Non-debt Instruments) Rules, 2019 sets a pricing floor for issue to a non-resident and a ceiling for transfer to a resident. Fair value follows any internationally accepted pricing methodology on an arm’s length basis, certified by a chartered accountant, a SEBI-registered merchant banker or a practising cost accountant ([ICSI, 2024](https://www.icsi.edu/media/filer_public/29/9f/299fe2b9-4729-4ff7-9b73-f5a796c557ad/presentation_on_fdi-_17th_august_2024.pdf)). The pricing rule itself is covered in our guide on [how startup valuation works in India](https://treelife.in/startups/how-startup-valuation-works-in-india/). The 2026 amendments to the NDI Rules (First to Fourth Amendment Rules, 2026, the latest notified on 02/09/2026) and the reporting regulations amended on 13/06/2026 left the Rule 21 pricing rule as it was. RBI’s draft Foreign Exchange Management (Foreign Investment) Rules, 2026, released on 21/07/2026, would replace the NDI Rules and carry the pricing framework over with little change. The NDI Rules stay operative until final rules are notified, so check the rules in force on the transaction date. The review question is narrower: do the model’s numbers support the certificate?

DCF is one acceptable method, not a mandatory one. Where a DCF supports the certificate, the reviewer tests:

- The discount rate build-up and the terminal value assumption

- The fully diluted share count, including CCPS conversion and unexercised options

- The valuation date against the planned allotment date, since authorised dealer banks commonly expect the report to be no more than 90 days old at allotment

- Currency and unit consistency between the valuation sheet and the pricing sheet

The reviewer is not the certifier. The certificate remains with the chartered accountant, merchant banker or cost accountant who signs it.

### What does SEBI require of an AIF valuation model?

Category I and Category II AIFs must value investments at least once every six months through an independent valuer (Regulation 23(2), SEBI (AIF) Regulations, 2012), and Category III AIFs must keep NAV calculation independent of the fund management function (Regulation 23(3)) ([SEBI circular dated 06/02/2026](https://nsdl.com/nsdl/2026-05/04_SEBI_Circular_dated_6_February_2026.pdf)). The standardised framework from SEBI’s circular of 21/06/2023 now sits in the [Master Circular for AIFs dated 03/06/2026](https://www.sebi.gov.in/legal/master-circulars/jun-2026/master-circular-for-alternative-investment-funds-aifs-_101817.html), last updated 16/06/2026, which supersedes the 07/05/2024 version.

A fund model review tests the distribution waterfall, carry and clawback logic against the LPA, and the valuation inputs against that framework. For the valuation mechanics themselves, see our note on [AIF valuation in India](https://treelife.in/finance/aif-valuation-in-india/).

### What do the RBI Project Finance Directions mean for a lender’s model review?

The RBI (Project Finance) Directions, 2025 (RBI/2025-26/59, dated 19/06/2025) took effect on 01/10/2025. They cover project finance exposures of commercial banks, NBFCs, primary urban co-operative banks and all-India financial institutions, and exclude projects that reached financial closure before that date unless a fresh credit event or material change follows ([RBI press release, 19/06/2025](https://www.rbi.org.in/scripts/BS_PressReleaseDisplay.aspx?prid=60678)).

Three conditions touch the model directly: the original DCCO and the disbursement schedule are documented before any disbursement, the repayment tenor, including any moratorium, cannot exceed 85% of the project’s economic life, and disbursements track completion certified by the lenders’ independent engineer ([RBI (Project Finance) Directions, 2025](https://www.rbi.org.in/scripts/NotificationUser.aspx?Id=12873&Mode=0)). DCCO deferment keeps an account standard only within limits, which are three years for infrastructure projects and two years for non-infrastructure projects. The independent engineer certifies physical progress, not the spreadsheet. The model reviewer tests the repayment profile against the 85% limit, the DCCO extension case and the way cost overruns are funded.

## What does a financial model review report contain?

A financial model review report has five parts: a scope and limitations statement, a red-flag summary of show-stopping issues, an issue log with severity ratings, reconciliation and stress-test results, and a closing letter or conclusion. Findings move through iterations until the builder closes them or the reviewer records them as residual risk. Most engagements end with a walkthrough session with the model owner, so the findings are explained and the fixes agreed.

The issue log is the working document. A usable one reads like this:

**Table 6: Illustrative issue log extract**

IDLocationFindingSeverityEffect on outputs07Revenue sheet, row 42, month 14 onwardFormula overwritten with a typed valueCriticalRevenue overstated in all later periods; flows to EBITDA and DCF12Debt schedule, interest lineInterest on closing balance; sanction letter specifies average balanceMajorInterest understated; DSCR overstated in construction years19Cap table sheetFully diluted count omits the pool top-upMajorValue per share overstated23DashboardChart axis labelled ₹ crore, data held in ₹ lakhPresentationalNone on outputs; misleading display

Whatever the layout, a usable log carries:

- An issue number and the sheet and cell range affected

- A plain description of what is wrong and why it matters

- A severity grade: critical, major, minor or presentational

- The effect on headline outputs such as valuation, IRR or DSCR

- The recommended fix and its status after each iteration

The expectation gap sits in what a standard review does not cover. Standard scopes exclude the commercial merits and the reliability of input data, which is why those layers need separate scope.

**Table 7: What a standard review confirms and what needs separate scope**

LayerQuestion it answersIn a standard reviewNeeds separate scopeArithmetic and formula integrityDo the numbers calculate as designed?YesNoLogic against documentsDoes the model reflect the term sheet, SHA or loan terms?Yes, for documents suppliedDocuments not suppliedStatutory treatmentAre tax, FEMA and SEBI rules applied correctly?Only if agreed in scopeSpecialist tax or valuation reviewAssumption reasonablenessAre growth, churn and margin inputs credible?Internal consistency onlyMarket benchmarking exerciseCommercial feasibilityWill the plan work?NoBusiness or technical due diligence

Buyers most often misread rows three and four. They expect the review to say whether the projections are believable. A standard review says whether the projections are internally consistent and faithful to the paper. Those are different products, priced differently.

## How long does a financial model review take, and what does it cost?

Duration depends on model size, circular references, macros, the number of scenarios and how many iterations the builder needs. Published ranges from providers run from one to two days for a scan to about two weeks for a first full report. We have not published a rupee rate card, because fees move with scope.

Reference points drawn from provider-published offers in 2026 (estimates, not quotes):

- Scans are typically delivered in days, comfort reviews in about a week and full audits in two to three weeks.

- A red-flag report on show-stopper issues within about a week, a first full report in about two weeks and later iterations in a few working days each is a common structure.

- Fixed fees with an agreed number of iterations in a defined window, and capped hourly rates beyond it, are the common fee structure.

- Reviewers commonly advise completing the review two to four weeks before you start pitching.

Cost moves with these drivers:

- Number of sheets, rows of formulas and presence of macros or circularity

- Number of scenarios and sensitivities to be re-run

- Number of source documents to reconcile against

- Depth of the tier and whether Indian tax or FEMA review is in scope

- Number of iterations included and the turnaround required

To get a quote that compares like with like, send the model file with its version history, the assumptions book, the term sheet or loan documents, the latest audited financials and management accounts, the cap table, and a one-line statement of who will read the conclusion and by when. Ask two providers to quote the same scope. A fixed fee with a named iteration count is easier to compare than an hourly estimate.

## How do you choose among financial model audit firms in India?

Choose financial model review services in India on independence, method, Indian regulatory depth and written scope, in that order. A provider that built your model cannot review it. One that cannot name its test method, show a sample issue log or state its liability position in the engagement letter has not yet defined the product it is selling.

**Table 8: Provider types compared**

These are general patterns, not rankings.

Put seven questions to any provider before signing:

- Did anyone on your team build or advise on this model?

- Which test method will you run: formula inspection, independent replication or both?

- Can I see an anonymised issue log?

- Who reviews Indian tax, FEMA and SEBI treatment, and is it in scope?

- Is the engagement an advisory review or an assurance engagement under SAE 3400?

- How many iterations does the fee cover, and what happens beyond them?

- What are the liability cap and reliance terms, and who may rely on the letter?

## Common mistakes that cost founders time and money

Five mistakes account for most wasted reviews. Each has a cheaper route.

- **Commissioning the review after the model is locked.** Teams book the reviewer in the week of close, so structural faults cost days they do not have. Problems found before the model is locked cost days, while the same problems found in the week of close cost the timetable. Book the review when the model is stable and the documents are signed in draft.

- **Leaving the purpose off the brief.** A review without a stated audience defaults to arithmetic. A lender, an investor and a valuer each need a different conclusion. Write the audience and the decision on the first page of the brief.

- **Buying a valuation report for the wrong provision.** Rule 11UA became Rule 57 on 01/04/2026, and the angel tax provision in Section 56(2)(viib) of the Income Tax Act, 1961 stood omitted from AY 2025-26 under the Finance Act, 2024. A report ordered from an old template can satisfy no provision in force, while the Companies Act or FEMA report actually needed goes missing. A FEMA pricing contravention can attract a penalty of up to three times the sum involved where the amount is quantifiable (Section 13(1), FEMA 1999). Map each report to a provision in force before commissioning it.

- **Reviewing the spreadsheet but not the paper.** A model that calculates correctly can still contradict the SHA on liquidation preference or the sanction letter on repayment start. Send the signed or near-final documents with the model so the reviewer can reconcile logic to paper.

- **Changing the model mid-review without a change log.** Each unlogged edit restarts part of the work and inflates iterations. Freeze a version, log every change, and release revised files in one batch per iteration.

## Treelife practitioner note

In the financial model review engagements we have run at Treelife, formula errors are rarely what moves a decision. The break that matters most is a model that no longer agrees with its own paper. A cap table updated after an ESOP grant, a CCPS conversion ratio changed in the amended SHA, or a sanction letter that moved the repayment start date, none of which reached the spreadsheet. Each one shifts value per share or debt service cover by more than a stray formula would.

Two checks catch most of it. First, build the fully diluted share count from the cap table and the ESOP register, then compare it with the count the model uses on its valuation and returns sheets. Where the model feeds a pricing certificate under Rule 21 of the FEM (Non-debt Instruments) Rules, 2019, the valuation date and the transaction date should also sit inside the 90-day window that authorised dealer banks commonly expect, or the certificate supporting the Form FC-GPR filing may have to be refreshed. Second, tie the first twelve months of the forecast to the latest MIS, not to the last audited year. Investors and lenders test the near term first, and a base month that does not reconcile loses the room before the long-term case is read.

A review works best when the builder joins the walkthrough. Ask the model owner to name the three assumptions they trust least. The issue log usually starts there.

## Where to start with a financial model review

The best financial model review services India offers share three traits: independence from the model builder, a named test method, and a scope that covers the Indian rules your audience will check. Before you request a quote, do four things.

- Write one page stating who will read the conclusion, what decision it supports and the date it is needed.

- Freeze a version of the model and assemble the assumptions book and the signed or near-final documents.

- List every report the model feeds, and map each one to a live provision: Rule 57, FEMA Rule 21, SEBI Regulation 23 or the RBI Project Finance Directions.

- Ask two providers to quote the same tier, with the same iteration count, and send them the seven questions above.

For model builds rather than reviews, our [financial modelling guide](https://treelife.in/finance/financial-modeling-for-startups/) covers workbook structure and KPIs. For cash planning that sits alongside the model, see [cash flow forecasting](https://treelife.in/finance/cash-flow-forecasting-for-startups/).

## FAQs on financial model review services in India

**Q: Does Rule 57 change how I value shares in my model?** 
A: It changes the rule number and the Act the rule sits under. Rule 57 of the Income-tax Rules, 2026 now holds the fair market value rule formerly numbered 11UA. The reviewer confirms that each valuation in the model names the provision it serves and that the method suits it. For the valuation rules, see our guide on [how startup valuation works in India](https://treelife.in/startups/how-startup-valuation-works-in-india/).

**Q: Do older section references in my model still work after 01/04/2026?** 
A: No. The Income-tax Act, 2025 replaced the 1961 Act from 01/04/2026, so section references and timelines written for the old Act need remapping. A reviewer flags every tax line that cites a 1961 section and confirms the treatment against the current text on the Income Tax Department portal.

**Q: How much do financial model review services cost in India?** 
A: Fees depend on the tier, model complexity, documents to reconcile and iterations included. Published global providers quote fixed fees per tier, and some list entry prices in US dollars. Ask two Indian providers to quote the same scope and compare iteration counts before comparing totals.

**Q: Is the fee fixed or hourly?** 
A: A fixed fee with a named number of iterations is the market norm among published providers, with capped hourly rates once the agreed window or iteration count is exceeded. Confirm the cap and the definition of an iteration in the engagement letter.

**Q: How long does a model review take end to end?** 
A: A scan takes 1 to 2 days and a full audit two to three weeks on typical market offers (estimate, 2026). Add time for iterations. Book the review when the model and documents are stable, ideally two to four weeks before you start pitching, not in the week of close.

**Q: What should I send with the model?** 
A: Send the model file with version history, the assumptions book, the term sheet, SHA or loan documents, the latest audited financials and MIS, the cap table and ESOP register, any existing valuation report, and a one-line note on audience and deadline. Missing documents are the most common cause of delay.

**Q: Why pay for an external review when we already have a CFO?** 
A: Because independence is the product. The builder tests what they meant to build, and lenders and investors want a reader who did not build it. Published research found major errors in most models reviewed (industry review reported at EuSpRIG 2001), including in models built by experienced teams.

**Q: Does a model review cover FEMA pricing?** 
A: Only if it is scoped in. The reviewer tests the DCF inputs, share count and valuation date behind a pricing certificate under Rule 21 of the FEM (Non-debt Instruments) Rules, 2019. The certificate itself comes from a chartered accountant, a SEBI-registered merchant banker or a practising cost accountant.

**Q: How does a reviewer treat a holding company or promoter group structure?** 
A: The reviewer tests consolidation, intercompany eliminations and related-party flows, and checks that loans and cost allocations between entities net out correctly. Where co-founders hold through different vehicles, the reviewer also confirms that vesting and equity splits flow into the cap table used for valuation.

**Q: What if my model assumes a tax benefit for a DPIIT-recognised startup?** 
A: The reviewer checks eligibility against the current text on the [Startup India](https://www.startupindia.gov.in) and [Income Tax Department](https://www.incometaxindia.gov.in) portals. The startup deduction sat in Section 80-IAC of the 1961 Act and moves to Section 140 of the Income-tax Act, 2025 from tax year 2026-27. It needs a separate Inter-Ministerial Board certificate and applies only to companies and LLPs incorporated before 01/04/2030, and the DPIIT definition limits were revised in 2026. Do not carry the benefit into the base case until eligibility is documented.

**Q: What happens if the review finds a critical error after a term sheet is signed?** 
A: Disclose it early and correct it before definitive documents are signed. A corrected model with a change log costs a conversation. An error the investor finds after signing can reopen price. Record the error, its effect on headline outputs and the fix in the issue log.

**Q: Can an investor commission a review of my model?** 
A: Yes, and it is common before closing. Agree scope, access to the file, who owns the report and who may rely on it before the work starts. A reliance letter should name the parties. Company-side review before the investor’s own makes their issue log shorter.

**Q: How does a reviewer test ESOP dilution?** 
A: The reviewer reconciles the pool size, granted, vested and exercised options and any CCPS conversion to the cap table and the ESOP plan, then confirms the fully diluted count used on the valuation and returns sheets. For the valuation inputs themselves, see our note on [ESOP valuation services](https://treelife.in/legal/esop-valuation-services-in-india/).

**Q: Does an NRI founder or foreign investor change the review?** 
A: Yes. Funds from abroad and share transfers between residents and non-residents fall under the pricing rules in Rule 21 of the Non-debt Instruments Rules, 2019. The model must show the floor or ceiling price that applies, the currency conversion date and the valuation date used. The 2026 amendments revised the treatment of investors with beneficial ownership linked to land-border countries, so the cap table should carry ultimate beneficial owners.

**Q: Can an AI-built or AI-assisted model be reviewed the same way?** 
A: Yes, with the same tests. Add attention to hardcoded values pasted over formulas, unexplained assumptions and formulas nobody on the team can describe. The reviewer needs a log of where each input came from, since the builder may not be able to explain what the tool produced.
