India's Micro, Small and Medium Enterprises (MSME) Development Act, 2006 mandates that registered MSMEs receive payment for goods and services within 45 days of invoice; failure triggers automatic 1. 5% monthly interest. Yet most small suppliers—especially in manufacturing, textiles, and trading—either ignore this law or lack the confidence to enforce it. Working capital stress remains the single largest cash-flow killer for SMEs. This article explains how the 45-day rule works, when it applies, and how to operationalise it.
Advisory
Udyam registration crossed 3 crore cumulative registrations by mid-2026. Larger buyers now face reputational and ESG pressure to settle MSME invoices on time, making the 45-day rule easier to enforce than it was five years ago.
GST e-invoicing platforms and fintech tools now embed automated 45-day countdown alerts. MSMEs can now flag overdue invoices in real time and escalate recovery before cash-flow stress becomes acute.
Large corporates and listed companies are increasingly audited on supplier-payment timelines as part of ESG governance. Repeated breach of the 45-day rule can trigger buyer audits, forcing compliance.
Under India's MSME Development Act, 2006 (amended 2018), any buyer—corporate, government, or individual—making purchases above ₹1 crore annually from registered MSMEs is legally bound by the 45-day payment window and automatic interest accrual on defaults. Violations can be escalated to the District MSME Authority or pursued through arbitration. Vinayakam Consultants helps MSMEs formalise invoice-settlement processes, automate 45-day tracking, document breaches for legal recovery, and structure payment terms in supply contracts so the burden of proof shifts to the buyer. We also advise larger firms on MSME payment policies to avoid penalties and reputational damage.
Your action checklist
- Verify your buyer qualifies under the MSME Act (annual purchase value from MSMEs ≥ ₹1 crore). If yes, register your Udyam code on the buyer's procurement system and formally notify them of the 45-day rule in writing at contract outset.
- Embed a 45-day payment term into every supply or service contract; include the automatic 1.5% monthly interest clause and specify the calculation method (simple interest on unpaid invoice amount from day 46 onwards).
- Set up a payment-tracking spreadsheet (or fintech tool) that flags each invoice on day 35; prepare a written reminder by day 40 citing the MSME Act section 22; escalate to the buyer's CFO or procurement head by day 43 if no payment movement is visible.
- Document every late payment with invoice copies, payment proof dates, and correspondence; lodge a formal complaint with your District MSME Authority or file for interest recovery through arbitration if a single invoice remains unpaid beyond 60 days—persistence is more effective than informal pressure.
