Late payment is one of the biggest problems for Indian small businesses. You’ve delivered the goods or done the work, paid your staff and suppliers, and the customer still hasn’t paid. A few slow payers can leave a profitable business unable to pay its own bills.
The good news is that most late payments can be prevented with clear terms and good habits, and Indian law gives micro and small enterprises strong rights against buyers who pay late. This guide covers both.
Key points
Table of Contents
- Agree payment terms in writing before you start, and put them on every quote and invoice.
- Take advances for custom work and new customers, and use staged payments for large jobs.
- Make paying easy: UPI QR codes, payment links and bank details on every invoice.
- Follow up early and politely, on a fixed schedule.
- If you’re a registered micro or small enterprise, buyers must pay within the agreed period, which can’t exceed 45 days. Late payers owe compound interest at three times the bank rate, and you can file a case on MSME Samadhaan.
- Income tax rules also push business buyers to pay registered micro and small suppliers on time.
Prevention: set yourself up to be paid
Clear terms
Before you take an order, agree:
- the price, and whether it includes GST
- what’s included, and how extras are charged
- when payment is due: on delivery, within 7 days, within 30 days, or in stages
- how to pay, and any late payment interest
Write them on your quote, order confirmation and invoice. A short WhatsApp message confirming the terms is better than nothing.
Advances and staged payments
- New or unknown customers: ask for a full or part advance.
- Custom work (furniture, tailoring, interior projects, events, bulk orders): take an advance large enough to cover your materials.
- Large jobs: split payments into stages tied to milestones, such as an advance, a payment on design approval, a payment mid-way and the balance on completion.
Good invoices, sent on time
Send the invoice the day you deliver, not at the end of the month. Include your name, address and GSTIN if registered, the customer’s details, a unique invoice number and date, the items and amounts, the payment due date, and your UPI QR code or bank details. If you’re Udyam-registered, add your Udyam number so the buyer knows your rights. Make professional invoices free with Advanton’s GST invoice generator.
Make paying easy
Put a UPI QR code on the invoice, send UPI payment links on WhatsApp, and share your bank details for NEFT and IMPS. For recurring customers, use UPI AutoPay mandates. See UPI and digital payments for small businesses.
Credit with limits
If you sell on credit (udhaar), set a limit and a settlement date for each customer, record every credit sale, and stop new credit for anyone behind on payments.
Follow-up: a simple schedule
- A few days before the due date: a friendly reminder with the invoice and payment link.
- On the due date: "Your payment of ₹X for invoice no. Y is due today. Here’s the link to pay."
- One week late: a firmer message, and a phone call. Ask when payment will be made, and note the date.
- Two to three weeks late: a formal written reminder, mentioning interest under your terms or under the MSMED Act if you’re a registered micro or small enterprise.
- 30 days or more: stop further supplies on credit, and consider the formal remedies below.
Keep a list of who owes what and since when, and review it every week. See bookkeeping basics.
Reminder messages you can use
Polite, specific messages work best. Adapt these for WhatsApp or email:
Before the due date:
"Namaste [name], a quick reminder that invoice no. [number] for ₹[amount] is due on [date]. You can pay by UPI using this link: [link]. Thank you for your business."
On the due date:
"Hello [name], invoice no. [number] for ₹[amount] is due today. Here’s the UPI link and our bank details in case that’s easier: [details]. Please let me know once it’s done."
One week overdue:
"Hello [name], our records show invoice no. [number] for ₹[amount] is now a week overdue. Could you let me know when we can expect payment? If there’s a problem with the invoice, I’m happy to sort it out."
Three weeks overdue (to a business buyer, if you’re Udyam-registered):
"Dear [name], invoice no. [number] for ₹[amount], due on [date], remains unpaid. As a registered micro enterprise (Udyam no. [number]), we’re entitled to interest on delayed payments under the MSMED Act. We’d prefer to settle this simply. Please arrange payment by [date], or call me to discuss."
Always keep a record of reminders sent; it helps if you need to file on MSME Samadhaan later.
Your legal rights as a micro or small enterprise
The 45-day rule
Under the Micro, Small and Medium Enterprises Development (MSMED) Act, 2006, a buyer must pay a micro or small supplier:
- by the date agreed in writing, which can’t be more than 45 days from the day of acceptance of the goods or services, or
- within 15 days, if there’s no written agreement.
Interest on late payment
If the buyer pays late, they must pay compound interest with monthly rests at three times the bank rate notified by the Reserve Bank of India, from the due date. That’s a high rate, designed to discourage late payment. A buyer can’t claim this interest as a tax deduction.
These rights apply to micro and small enterprises, so register for Udyam, free. See our Udyam guide.
MSME Samadhaan and Facilitation Councils
If a buyer doesn’t pay, you can file an application on the government’s MSME Samadhaan portal. It’s sent to the Micro and Small Enterprises Facilitation Council (MSEFC) in your state, which first tries conciliation, and if that fails, arbitrates. Its award is binding. If the buyer challenges the award in court, they generally have to deposit 75% of the amount first. Filing is online and doesn’t need a lawyer, though one can help with larger claims.
The income tax rule that pushes buyers to pay
Since financial year 2023-24, a business buyer can claim a deduction for amounts owed to registered micro and small enterprises only in the year they actually pay, if they pay later than the time allowed under the MSMED Act. Under the Income-tax Act, 2025, this rule continues. In practice, many larger buyers now check their suppliers’ Udyam registration and pay registered micro and small suppliers within 45 days, especially before the financial year ends.
Other ways to get paid faster
TReDS
The Trade Receivables Discounting System (TReDS), regulated by the RBI, lets micro and small suppliers upload invoices accepted by large buyers and sell them to financiers at competitive rates, getting paid in days instead of waiting months. Large companies and public sector undertakings above set turnover limits must register on TReDS. Ask your large buyers whether they’re on a TReDS platform.
Cheque bounce
If a customer’s cheque bounces for insufficient funds, section 138 of the Negotiable Instruments Act gives you a remedy: send a legal notice within 30 days of learning about the bounce, give the drawer 15 days to pay, and if they don’t, you can file a complaint in court within the time limit. Many small businesses avoid cheques for this reason and prefer UPI or bank transfers.
Civil recovery
For large unpaid amounts, a lawyer can send a legal notice and, if needed, file a recovery suit. Commercial disputes above certain values go to commercial courts, which require an attempt at pre-institution mediation first in many cases. Courts take time, so prevention and MSME Samadhaan are usually better routes for small businesses.
When a customer can’t pay
Sometimes customers are genuinely struggling. Before going legal:
- agree a written payment plan with instalments
- take post-dated digital payment commitments, such as UPI AutoPay instalments
- stop further credit until the balance is cleared
- consider a modest discount for immediate payment of the full amount
A customer who pays in instalments is often better than a long legal fight.
Protect your cash flow
- Forecast your cash. Advanton’s cash and payroll planner shows unpaid invoices and when cash will run low.
- Don’t depend on one big customer. A late payment from a single large buyer can sink a small business.
- Keep a cash buffer of at least one to two months of fixed costs.
- Negotiate supplier terms that match your customers’ payment terms.
And keep new customers coming: list your business free in the India Business Directory.
Frequently asked questions
Does the 45-day rule apply to sales to consumers?
No. It applies to payments from buyers, which are businesses and organisations, to micro and small enterprise suppliers.
Do I need Udyam registration to use MSME Samadhaan?
Yes. Your rights under the MSMED Act depend on being a registered micro or small enterprise at the time of supply, so register early.
Can a buyer refuse to pay interest?
The interest is a legal right under the MSMED Act, and the Facilitation Council can award it.
What should I put on my invoice to help?
Your Udyam number, the payment due date, your UPI QR code and bank details, and a line stating that interest applies on late payment as per the MSMED Act.
