Small suppliers facing the cashflow terror, invoice-chasing and power imbalance of late or non-paying clients, and the personal-debt and mental-health toll that follows.
Late and non-payment is a systemic pattern, not a personal failing, and Indian law is genuinely protective: a buyer must pay a registered micro or small enterprise within 45 days (15 if there is no written agreement), late payment attracts compound interest at three times the RBI bank rate, and the free MSME Samadhaan portal lets you file against a buyer with no court fee. Since 1 April 2024, Section 43B(h) also means a buyer can deduct your invoice only in the year they actually pay it. Filing is not overreaction, it is self-respect backed by law.

A single large buyer holding back beyond 45 days can choke your working capital and push you into credit-card or family debt. That stress sits in the body, the night-time UPI-checking, the shame of explaining to staff and family. This page validates that, gives you practical get-paid tactics and escalation scripts, and humanises the formal remedies most suppliers never use.
Get-paid tactics before things go bad
Put scope and terms in writing and ask the client to reply 'Agreed' from an official email or issue a purchase order, this becomes the evidence if you ever escalate. Take a 30 to 50% advance (it is risk-management, not greed) and bill in milestones rather than everything at the end, with a clause that work pauses if a milestone is overdue beyond seven days. Use short, explicit due dates (7 to 14 days for small clients) and automate reminders, keeping every follow-up in writing.
The escalation sequence (lift these scripts)
Run a calm, documented ladder: a friendly reminder on the due date; a polite nudge at day 3 to 7 asking if any internal approval is pending; a firmer note at day 10 to 14 setting a specific pay-by date and stating work will pause; and a final pre-legal notice past 30 to 45 days that references the MSMED Act and your Udyam number. Email gives the best documentary value. Many buyers settle the moment a formal MSEFC notice lands in their inbox.
The MSME legal backbone, in plain language
Under Section 15 of the MSMED Act, a buyer must pay a registered micro or small enterprise by the agreed date (maximum 45 days from acceptance) or within 15 days where there is no written agreement. Beyond that, Section 16 makes the buyer liable for compound interest at three times the RBI bank rate, with monthly rests, mandatory and non-waivable. The MSME Samadhaan portal (samadhaan.msme.gov.in) lets a Udyam-registered micro or small enterprise file a delayed-payment case to the state Micro and Small Enterprises Facilitation Council, with no court fee; the council conciliates and then arbitrates, and its award is enforceable as a decree.
A registered micro/small enterprise must be paid within 45 days (15 without a written agreement); delay attracts mandatory compound interest at 3x the RBI bank rate, enforceable via the MSEFC through the free Samadhaan portal.(MSMED Act 2006 ss.15-16 + s.18 (MSEFC); MSME Samadhaan portal)
Section 43B(h): the tax rule that makes buyers pay
From 1 April 2024, Section 43B(h) means a buyer who owes a micro or small enterprise can claim the expense as a deduction only in the year they actually pay you, if payment is beyond the MSMED Section 15 timeline, and, unlike other 43B clauses, paying before filing the return does not help. So delay raises the buyer's taxable profit. You can mention this to a finance team without threatening: as an MSME supplier, delayed payment beyond the MSMED timelines may be disallowed under 43B(h), affecting your deduction, so timely processing helps us both.
A buyer gets the deduction for a micro/small-enterprise invoice only in the year of actual payment if paid beyond the MSMED timeline; the usual pay-before-filing relief does not apply.(Income-tax Act 1961 s.43B(h) (effective 1 April 2024; 2025 Act s.37 actual-payment clause))

Allowable expenses in context
Statutory interest you actually receive on a delayed payment is taxable income. Professional or legal fees incurred in recovering a debt, and the cost of accounting and invoicing software, are deductible business expenses. If a genuine trade debt becomes irrecoverable and was previously recognised as income, it may qualify as a bad-debt write-off, take advice on the conditions. This is general information; seek advice from a professional for your situation.
A large client owes Farah Rs 1,80,000, now 70 days past the agreed date, and has stopped replying. She has the PO and email confirmation, and is Udyam-registered.
Past 45 days, the buyer is liable under MSMED Section 16 for compound interest at three times the RBI bank rate with monthly rests, mandatory and non-waivable. Farah sends a final notice referencing the Act and her Udyam number, then files free on the MSME Samadhaan portal to the state MSEFC. Separately, under Section 43B(h) the buyer cannot deduct her invoice until they actually pay, raising their tax, which is often what prompts settlement. The PO and email confirmation are the evidence that makes the case strong.
Frequently asked questions
Will I lose the client if I use MSME Samadhaan?+
It is a common fear, but the council exists precisely to reduce that power imbalance, and filing is free with no court fee. Many buyers settle as soon as a formal MSEFC notice arrives. If a buyer has clearly crossed 45 days and is ignoring you, using Samadhaan is self-respect backed by law, not overreaction.
How much interest can I claim on a late payment?+
Under Section 16 of the MSMED Act, a buyer who pays a registered micro or small enterprise late owes compound interest at three times the RBI bank rate, with monthly rests. It is mandatory and non-waivable, a council or court is not supposed to award less. Accepting late payment quietly means giving the buyer free, high-interest credit.
What is Section 43B(h) and how does it help me get paid?+
From 1 April 2024, a buyer can deduct what they owe a micro or small enterprise only in the year they actually pay, if payment is beyond the MSMED timeline, and paying just before filing the return does not fix it. So delay raises the buyer's tax. You can mention this to a finance team factually as a reason to process your invoice on time.
Do I need to be registered to use these protections?+
Yes, the MSMED delayed-payment protections and Samadhaan filing apply to Udyam-registered micro and small enterprises (traders and medium enterprises are generally excluded). Udyam registration is free and online, so register before you need to escalate; it also brings the Section 43B(h) rule into play on your buyers.
