Overview

Product costing advisory is the computation of the true cost of a product — the material, the labour and the overheads allocated to each unit, the direct and the indirect costs, the absorption and the marginal costing, and the cost-plus and the contribution analysis that decide the price and the profitability. The costing is the foundation of the pricing, the margin and the product decisions — the products to push, the products to fix and the products to drop.

The product cost is the number that the pricing and the profitability decisions are built on, and it is the number most businesses get approximately. The material cost that moves with the input prices, the labour that the process consumes, the overheads that must be absorbed across the products — each is a component of the true cost, and the allocation method decides the margin each product actually earns. The product whose cost was never computed properly is the product whose price was never set properly.

The cost of a wrong costing is the wrong pricing: the product priced below its true cost and the margin eroded on every sale, the product priced above the market and the volume lost, the product mix optimised on the wrong margins. Each is a leak that the accurate costing would have closed.

This service is for manufacturers and product businesses. We build the product costing model — the material, the labour and the overhead allocation — compute the unit costs and the contribution, analyse the product margins and the mix, set the cost-plus and the pricing positions, and review the costs as the inputs and the processes change — so the pricing is built on the true cost of every product.

Frequently Asked Questions

Which companies in India are mandatorily required to maintain cost records and get them audited?
Under Section 148 of the Companies Act 2013 read with the Companies (Cost Records and Audit) Rules 2014 (as amended), companies engaged in regulated and non-regulated sectors with a net worth exceeding ₹500 crore, or with a turnover exceeding ₹35 crore (for some regulated sectors like electricity, petroleum, pharmaceuticals) are required to maintain cost records in the prescribed form. The specific sectors covered are listed in Tables A and B of Rule 3 of the Cost Records and Audit Rules 2014. Companies in Table A (regulated sectors including electricity, telecom, petroleum) meeting threshold criteria are also required to undergo mandatory cost audit, and the cost auditor must be a practising Cost and Management Accountant appointed by the Board with ROC intimation in Form CRA-2 within 30 days of appointment. The cost audit report must be filed in Form CRA-4 with the MCA within 180 days of the close of the financial year.
What is the difference between cost records under Companies Act and cost accounting standards issued by ICAI?
Cost records under Rule 5 of the Companies (Cost Records and Audit) Rules 2014 are the minimum statutory record-keeping requirements — including records of cost of material, labour, utilities, depreciation, overheads, and cost of production per unit — and are mandatory for prescribed companies. Cost Accounting Standards (CAS) issued by the Institute of Cost Accountants of India (ICAI-CMA) — CAS 1 through CAS 24 — are professional standards that provide detailed guidance on how cost elements should be computed, classified, and allocated, and are referenced in the Cost Audit Report format under Form CRA-3. While CAS compliance is not independently legislated, the MCA's General Circular 67/2011 clarified that cost records maintained under the Rules must be consistent with the applicable CAS where relevant. For product costing advisory engagements, alignment with CAS 4 (Cost of Production for Captive Consumption) and CAS 6 (Material Cost) is particularly important for transfer pricing and excise duty (now GST) benchmarking.
How does product costing interact with GST valuation when goods are transferred between related parties or branches?
Where goods are transferred between related persons or between distinct persons (e.g., branch to branch within a GST registration) under Section 7 read with Schedule I of the CGST Act 2017, the transaction is deemed a supply even without consideration. The value of such deemed supply is determined under Section 15(4) read with Rules 28 to 31 of the CGST Rules 2017 — for related party transactions where the recipient is not entitled to full ITC, the value must not be less than the cost of production (determined using product costing methodology) plus a 10% markup. If the recipient is entitled to full ITC, the invoice value may be accepted even if below cost. Proper product costing records (material cost, conversion cost, overhead absorption) are therefore essential documentation to defend the GST valuation adopted in branch transfer invoices during a GST audit or scrutiny under Section 61 or 65 of the CGST Act 2017.
Can product costing data be used to support transfer pricing documentation for intragroup transactions?
Yes. For intragroup transactions involving goods manufactured by one group entity and supplied to an associated enterprise, the Comparable Uncontrolled Price (CUP) method or the Cost Plus method under Section 92C of the Income Tax Act 1961 read with Rule 10B(1)(b) and (c) of the Income Tax Rules 1962 relies on accurately computed cost of production. The Cost Plus method adds an arm's length gross profit markup to the direct and indirect costs of production to arrive at an arm's length price. The Transfer Pricing documentation required under Section 92D and Rule 10D must include the cost computation methodology, the CAS-aligned cost sheet, and the source of comparable gross margin data. Weaknesses in product costing — such as arbitrary overhead absorption rates or inconsistent treatment of by-products — are frequently targeted by the Transfer Pricing Officers during assessments under Section 92CA, and robust CAS-aligned cost records significantly strengthen the taxpayer's position.
How should joint product and by-product costs be allocated for accurate product costing under Indian standards?
Joint product and by-product cost allocation is addressed in CAS 17 (Joint Cost) issued by the Institute of Cost Accountants of India. Under CAS 17, joint costs (costs incurred up to the split-off point) must be apportioned among joint products on the basis of physical output, relative sales value at split-off point, or net realisable value (NRV) at the split-off point — the NRV method is generally preferred for its economic meaningfulness. By-products, being outputs of relatively minor economic value, may be credited against the joint cost at their NRV without being treated as a separate cost centre. For GST purposes, the methodology for allocating joint costs to individual products affects the cost base used for valuing branch transfers and captive supplies under Rule 28 of CGST Rules 2017. For mandatory cost record maintenance companies, the cost statement in Form CRA-1 requires separate product-wise cost sheets, necessitating a defensible and documented joint cost allocation policy.
