For an early-stage founder, tracking unit economics before you seek funding is essential not only for understanding your business performance but also for meeting Indian legal and regulatory requirements. Investors today expect founders to present credible numbers supported by clean accounting, statutory compliance, and robust documentation. In India, this means integrating the Companies Act, 2013, Goods and Services Tax (GST) laws, RBI payment regulations, Consumer Protection Rules, Income-tax Act provisions, Cost Audit Rules, and the Digital Personal Data Protection Act, 2023 into your financial tracking process.

In this article, CA Manish Mishra talks about How to Track Unit Economics Before You’re Investor-Ready.

Maintain Accurate Books Under the Companies Act

Under Section 128 of the Companies Act, 2013, every company must maintain proper books of account on an accrual basis using the double-entry system. This is the foundation of accurate unit economics because CAC (Customer Acquisition Cost), LTV (Lifetime Value), contribution margin, and payback calculations are only as reliable as the financial data feeding them. If you are using a cloud-based accounting platform, the Act requires you to disclose the location and service provider details when filing financial statements. Early adoption of a structured chart of accounts, proper cost categorization, and reconciliation processes will make your unit-level metrics verifiable during investor due diligence.

Link Unit Revenue to GST-Compliant Invoicing

Per-unit revenue figures must be consistent with your GST-compliant invoicing records. Under the Central Goods and Services Tax Act, 2017 and associated rules, you must issue tax invoices for taxable supplies and ensure they match your GST returns. If you cross the e-invoicing threshold, the law mandates generating Invoice Reference Numbers (IRNs) for B2B transactions via the Invoice Registration Portal (IRP). From April 1, 2025, a new rule requires invoices to be reported to the IRP within 30 days of issuance. Failure to comply can delay collections, distort Days Sales Outstanding (DSO), and skew cash flow assumptions in your unit economics model.

Capture All Variable Costs and Ensure RBI Payment Compliance

Variable costs like payment gateway charges, packaging, and logistics must be recorded accurately to calculate contribution margin. If you rely on recurring payments, the RBI’s e-mandate framework requires additional authentication for transactions above ₹5,000, impacting churn and renewal rates. Under RBI rules, payment aggregators (PAs) must be authorized, and only such licensed entities can handle settlements for merchants. If your payment partner faces authorization delays or regulatory action, settlement timelines can change, directly affecting your unit-level cash flow analysis. These payment compliance details must be factored into your financial model.

Factor in Consumer Protection and Refund Costs

If your business falls under the Consumer Protection (E-Commerce) Rules, 2020, you must comply with refund timelines, transparent return policies, and disclosure norms. Delays in refunds can lead to penalties and customer dissatisfaction, both of which influence churn rates and, ultimately, LTV. Since reverse logistics and refunds are variable costs, failure to track them accurately in compliance with these rules will result in misleading unit economics data.

Adjust for TDS/TCS and Direct Tax Impacts

When calculating unit economics, you cannot simply take gross invoice amounts as “revenue earned.” The Income-tax Act, 1961 contains specific provisions that require tax deductions at source (TDS) or tax collection at source (TCS) before payments are made. These deductions reduce the actual amount credited to your account, which in turn affects your per-unit revenue, contribution margin, and payback period calculations.

Key Provisions Impacting Net Revenue:

Section 194O – TDS by E-Commerce Operators:

• Applicable when sales are facilitated through an e-commerce platform (like Amazon, Flipkart, Zomato, Swiggy, etc.).

• The operator must deduct 1% TDS on the gross sales amount at the time of payment or credit to the seller, whichever is earlier.

• This deduction reduces the net receipts for the seller.

• Example: If the invoice value is ₹1,00,000, the e-commerce operator deducts ₹1,000 as TDS and remits ₹99,000 to you.

• Impact on Unit Economics: If you track per-unit revenue without adjusting for this deduction, your numbers will be inflated compared to the actual cash inflows.

Section 194Q – TDS by Buyers on Purchases:

• Applicable when a buyer’s turnover exceeds ₹10 crore in the preceding financial year.

• If such a buyer purchases goods worth more than ₹50 lakh from a single seller in a financial year, they must deduct 0.1% TDS on the purchase value exceeding ₹50 lakh.

• This affects businesses supplying to large corporate buyers or wholesalers.

• Impact on Unit Economics: The deduction may not seem significant (only 0.1%), but over multiple transactions, it changes realized revenue and the timing of cash flows.

Section 206C(1H) – TCS on Sale of Goods:

• Currently, sellers with turnover above ₹10 crore must collect 0.1% TCS from buyers (when sale value exceeds ₹50 lakh) and deposit it with the government.

• The Finance Bill 2025 proposes removing this TCS provision from April 1, 2025, to avoid duplication where Section 194Q already applies.

• This change will simplify compliance but requires ERP and invoicing system updates to stop charging TCS where it’s no longer applicable.

Why Adjust in Unit Economics:

• Overstated Revenue Risk: If you record only the invoice value and ignore these deductions, your revenue per unit appears higher than actual.

• Cash Flow Misalignment: TDS/TCS deducted amounts can only be claimed back as tax credits when filing returns, so they don’t immediately contribute to working capital.

• Payback Period Errors: Without adjustment, you may underestimate the time needed to recover acquisition and operational costs.

Best Practice for Compliance and Accuracy:

• Integrate your accounting/ERP with GST returns, bank statements, and TDS/TCS registers to track actual post-tax receipts.

• Automate Section 194O and 194Q deduction calculations to avoid manual errors.

• Update ERP for Finance Bill 2025 changes before April 1, 2025, to avoid mischarging customers.

Build Cost Accounting Discipline

The Companies (Cost Records and Audit) Rules, 2014 require companies in certain sectors to maintain detailed cost records and, in some cases, undergo a cost audit. Even if you are not yet mandated to do so, implementing cost accounting practices at the SKU or service level improves your understanding of per-unit profitability. This approach helps ensure that all direct and indirect costs are captured, leading to more accurate contribution margin calculations and making your business more investor-ready.

Include Data Protection Compliance Costs

If your LTV calculations depend on customer data for targeted marketing or retention strategies, you must comply with the Digital Personal Data Protection Act, 2023 and forthcoming rules. This includes obtaining valid consent, implementing secure storage, following data minimization principles, and enabling user rights such as deletion and portability. Non-compliance can lead to fines, forced operational changes, and even reduced marketing effectiveness all of which can negatively impact your projected LTV and unit economics.

Design a Compliance-Aware Unit Economics Model

To make your unit economics legally defensible, define your “unit” precisely whether it’s a transaction, subscription, or active customer. Compute revenue net of GST, refunds, platform commissions, and TDS/TCS deductions. Record costs after including merchant discount rates, logistics expenses, chargebacks, and support costs. Attribute marketing expenses honestly to CAC, and prepare both accrual and cash-based analyses to give a complete view of runway and profitability. Tie each assumption, such as settlement periods or refund SLAs, to the corresponding legal or contractual requirement.

Prepare for Investor Due Diligence

This point emphasizes that investor due diligence goes beyond just reviewing your revenue or profit numbers they also want to see the process behind those numbers.

You should:

• Reconcile IRP e-invoices, GST returns, and bank statements monthly to prove your revenue figures are accurate and tax-compliant.

• Maintain TDS/TCS registers linked to statutory challans so all tax deductions and collections are traceable.

• Keep settlement reports from payment partners to ensure that the amounts credited match your books and revenue recognition policy.

• Document refunds in line with Consumer Protection Act timelines, showing customer disputes are handled legally.

• Preserve DPDP Act compliant consent logs and deletion records to demonstrate you manage user data lawfully.

Following these practices ensures your unit economics are both financially credible and legally compliant, reducing investor concerns during funding evaluations.

Conclusion

Tracking unit economics in India before becoming investor-ready is as much about compliance as it is about financial acumen. By embedding the requirements of the Companies Act, GST laws, RBI payment rules, Consumer Protection Rules, Income-tax provisions, Cost Audit Rules, and Data Protection Act into your metric tracking, you create a model that is credible, transparent, and audit-ready. This not only improves your operational decision-making but also strengthens your position when you eventually face investor scrutiny, helping you raise capital confidently and sustainably.
