The India Manufacturing Business Case: How to Build One That Survives Review

An India manufacturing business case is not a labour-cost comparison. It is a landed-cost, capital and risk case — and it is usually won or lost on ramp assumptions and incentive treatment rather than on the unit cost that opens the deck.

This page sets out how the case is constructed and what an investment committee will attack. The pillar hub covers whether India is the right country at all; this page covers whether the numbers hold once you have decided to look seriously.

Direct answer

How do you build a business case for manufacturing in India?

Build the case on fully landed cost to the customer, not on factory-gate or labour cost. Model four blocks separately: the capital required to reach production, the run-state cost structure at realistic yield and utilisation, the incentives that are actually realisable under the conditions attached to them, and the risk value of diversifying supply away from a concentrated source. Then test the case against the ramp curve rather than the steady state — most India manufacturing cases that fail in review fail because they assume design capacity from month one, treat incentive quantum as certain, or omit the working capital that a longer inbound supply chain requires.

Why India manufacturing cases fail in review

The typical first-draft case compares an Indian unit cost with an incumbent unit cost, applies a saving to current volume and presents a payback. It rarely survives contact with a capital committee, because none of the three numbers being compared are the numbers that decide the outcome.

Unit cost at the factory gate is not what the business pays. What it pays is landed cost: material and conversion, plus inbound logistics on components that may still be imported, plus duty, plus outbound freight to the markets served, plus the cost of quality escapes during ramp, plus the working capital tied up in a longer pipeline. A conversion-cost advantage can be entirely consumed by an import-heavy bill of materials, and frequently is in the first two years.

The second failure is treating incentives as revenue. Central and state incentives in India are real and material, but they are conditional — on investment thresholds, on committed employment, on domestic value addition, on timelines and on claim discipline. A case that books incentive quantum at full value on schedule is not a business case, it is a best case.

The third failure is the ramp. Yield, scrap, line rate, supervisor capability and supplier reliability all mature over quarters, not weeks. A case built on design capacity understates cost in exactly the period when cash is tightest and the programme is most exposed to reversal.

The four blocks of a defensible case

Model these separately and keep them separately auditable. Blending them into a single cost-per-unit is what makes a case impossible to challenge — and therefore impossible to approve with confidence.

NirjiX India Manufacturing Business Case Framework

  1. 01

    Capital to production

    Land or built-to-suit lease, building and utilities, plant and equipment, tooling, IT and OT systems, certification, and the pre-operative cost of the entity, approvals and team. Include the cost of the parallel run with the incumbent source, which is routinely omitted.

  2. 02

    Run-state cost structure

    Landed cost at realistic yield and utilisation: bill of materials with the actual localisation mix, conversion cost, logistics inbound and outbound, duty, quality cost and overhead. Model it at ramp-year utilisation and at steady state, and show both.

  3. 03

    Realisable incentive value

    Central schemes and the applicable state package, each carried at the value you can defend under its conditions and disbursement reality — not at the headline. Treat capital subsidies, duty benefits and output-linked incentives as three different cash profiles, because they are.

  4. 04

    Risk and option value

    The value of reducing single-source concentration, tariff exposure and lead-time risk, plus the option to serve India and adjacent markets from inside the tariff wall. This is the block most often left out entirely, and often the one that decides a marginal case.

The four blocks answer four different committee questions: how much do we commit, what does it cost to run, how much comes back and why is it worth the risk. A case that cannot answer them independently will be sent back regardless of its headline return.

The assumptions that actually move the answer

In NirjiX engagements, sensitivity is concentrated in a small number of variables. These are the ones worth arguing about; the rest are rounding.

Sensitivity ranking reflects NirjiX engagement experience across manufacturing feasibility studies. Ranges are engagement-specific and are not published as benchmarks.
AssumptionWhy it dominatesHow to test it
Localisation of the bill of materialsDetermines how much of the conversion advantage survives inbound logistics and duty. An import-heavy BOM can neutralise the case entirely.Build the BOM line by line with a localisation year for each item, and run the case at the year-one mix, not the target mix.
Ramp curve to stable yieldGoverns cost and cash in the period of maximum exposure, and sets when incentive conditions can realistically be met.Model quarterly yield and utilisation with a named owner for each milestone; compare against a comparable plant's actual ramp, not a plan.
Incentive realisationChanges both the return and the cash profile. Conditions, timelines and claim discipline decide what is actually received.Carry a base case at conditions you can meet without heroics, and show the case standing without incentives at all.
Working capitalLonger inbound pipelines and buffer stock during ramp absorb cash that unit-cost models never show.Model days of inventory across the ramp explicitly and fund it in the capital ask.
Labour productivity, not labour rateRate advantages are widely known and already priced in; output per person at your quality standard is what varies between operators.Benchmark against comparable plants in the same state and sector, with the same automation level.
Duty and tariff structure on your specific tariff linesComponent duty, export benefits and destination tariffs vary by line and change with policy.Confirm each tariff line as part of feasibility, and re-confirm before capital release.

Does the case justify going further?

Four sequential questions. A no at any point does not necessarily kill the programme — it changes what must be resolved before capital is committed.

  1. Question 01

    Does the case hold on landed cost with a year-one bill of materials, before any incentive?

    Yes

    The economics are structural. Incentives improve returns rather than create them, which is the strongest position for a capital committee.

    No

    Test whether localisation or an operating-model change (contract manufacturing first, own plant later) closes the gap before assuming incentives will.

  2. Question 02

    Can you meet the conditions attached to the incentives you are counting on?

    Yes

    Carry them at a defensible value with the disbursement profile modelled, and state the conditions on the same page as the number.

    No

    Remove them from the base case. An incentive you cannot condition-comply with is a risk, not a return.

  3. Question 03

    Is the ramp funded — capital, working capital and the parallel run with the incumbent source?

    Yes

    Proceed to location and operating-model design, where the assumptions become site-specific.

    No

    Re-scope phase one. Under-funding the ramp is the most common cause of an India programme stalling after approval.

  4. Question 04

    Does the risk block stand on its own — concentration, tariff exposure, lead time, market access?

    Yes

    You have a case that survives a cost-only challenge, because the value is not purely cost.

    No

    The programme is a pure cost play and will be judged only on cost. Make sure the cost advantage is large enough to justify the execution risk.

The purpose of the sequence is to separate the questions that require analysis from the questions that require a decision. Most stalled programmes have conflated the two.

What the investment committee will ask

  • What does the case look like with zero incentive realisation, and are we still willing to proceed?
  • Who owns this programme end to end, and what happens to it if they leave?
  • What is our exit if the ramp misses by two quarters — do we have a contract-manufacturing bridge?
  • How much of the saving is structural and how much is a one-off from current freight or currency conditions?
  • Which customers or approvals require plant qualification, and how long does that take after commissioning?
  • What is the plan for the incumbent source during and after transition, including the cost of running both?

Prepare these answers before the paper goes in. Each of them has ended a review that the numbers alone would have passed.

NirjiX view

The NirjiX view

The strongest India manufacturing cases we see are the ones that would proceed without incentives. Incentives then convert a good return into an unusually good one, and the programme is not hostage to a claim process it does not control.

The weakest are the ones that lead with unit cost. They are the easiest to write, the easiest to challenge, and the ones most likely to be approved on a number the business later cannot reproduce.

Our practical test: if the case cannot be stated in four numbers — capital committed, landed cost at ramp-year utilisation, incentive value at conditions you can meet, and the risk reduction being bought — it is not ready for a committee.

Frequently asked executive questions

How long does it take to build a credible India manufacturing business case?
A defensible case typically takes six to twelve weeks, because the inputs that decide the answer — bill-of-materials localisation, tariff lines, state incentive terms and a realistic ramp curve — have to be sourced rather than assumed. A directional feasibility view can be produced faster, but it should not be used to release capital.
Should incentives be included in the base case?
Include only the value you can defend under the conditions attached to the scheme, with the disbursement timing modelled. Always show the case without incentives as well. An investment committee that sees both will trust the number that includes them; one that sees only the incentive-loaded case usually will not.
What payback period is normal for an India manufacturing investment?
There is no universal figure, and any published one should be treated with suspicion. Payback depends on sector, capital intensity, localisation, incentive package and the ramp curve. What matters is that the payback is calculated on landed cost at realistic utilisation and includes working capital, not on steady-state factory-gate cost.
Is labour cost still the main reason to manufacture in India?
Rarely. Labour is a component, but the decision cases we see are driven by market access inside a large and growing domestic market, supply-chain diversification away from concentrated sourcing, an engineering and supplier ecosystem that supports localisation over time, and the incentive environment. Companies that go for labour cost alone are usually disappointed by productivity in year one.
How should China+1 risk be valued in the case?
Value it as avoided exposure rather than as a saving: the cost of a disruption at your concentrated source, multiplied by a probability you are willing to defend, plus the tariff differential you currently carry. Stating it explicitly is better than folding it into an optimistic cost assumption, because it survives scrutiny.
What is the most common error in first-draft cases?
Assuming the target localisation mix in year one. It is the single assumption that most often turns a positive case negative when corrected, because it changes both the bill of materials and the duty exposure.
