In short. Which route gets your unpaid invoices paid depends on four things. Is the claim still inside the three-year limit? Are you registered as a micro or small enterprise? How good is your paperwork? And can the buyer actually pay? In most files we start with a legal notice, then go either to the MSME Facilitation Council (if you qualify) or to Section 12A mediation followed by a commercial suit. This guide is for suppliers and service firms trying to pick a route. Make the call within two to three weeks of an invoice going badly overdue.
Is this your situation?
- Three invoices are now 60, 90 and 180 days past due. Your reminders get read, going by the blue ticks, and ignored.
- Someone said send a notice, your CA said try the MSME Council, a friend said go straight to court. You don't know which.
- You're on Udyam, or could have registered and never got round to it, and you want to know if that changes anything.
- The buyer is a big listed company. Or a government department. Or a small trader in Sadar Bazar. You suspect it matters which.
- A couple of the oldest invoices are coming up on three years.
- The post-dated cheques bounced, or the quality complaints only started after you billed.
- You'd like to spend in proportion to what's at stake, and not a rupee more.
Which way of recovering unpaid invoices actually works?
For most suppliers and service firms there isn't one step. There's an order of steps. First the legal notice, then the forum that suits your facts. Micro and small enterprises registered on Udyam before the order was placed usually do better at the MSME Facilitation Council. The interest there is statutory, at three times the bank rate, and a buyer can't challenge the award without first depositing 75 percent of it. Everyone else, and anyone facing a buyer ready to contest the facts for years, goes the Section 12A mediation route and then files a commercial suit. Where the papers are good enough, make it a summary suit.
No single answer fits every file. Anyone who gives you one without seeing your papers is guessing. The right route turns on four things, and we take them one by one below. Time first. Is the claim still alive? Then status, which is whether you qualify as an MSME at all, and paper, meaning how well you can actually prove the debt. Last, the buyer. Who is it, and can it pay? Cheque bounce complaints and insolvency are separate tools that sit alongside these four, and we cover them briefly.
This page compares routes for invoice claims. If your contract has an arbitration clause, or you're weighing arbitration more generally, read our guide on picking between a commercial suit, arbitration and the MSME Council instead.
Check one: is the claim still in time?
Advocate B.K. Singh opens every unpaid invoice file the same way. He looks for two dates: the oldest unpaid invoice, and the last time the buyer admitted the debt in writing. Those two tell you how long you've got. Sometimes they tell you which routes are already closed. For goods sold and delivered with no fixed credit period, the Limitation Act, 1963 gives three years from delivery (Article 14). Where a credit period was agreed, the three years start when it ends (Article 15). Services run three years from when the work was done, under Article 18. And a running account may be governed by Article 1.
Two sections can rescue an old invoice. Section 18 gives you a fresh period from a signed written acknowledgment made before time ran out. That could be a balance confirmation, an email from the buyer admitting the dues, or sometimes a reply to your notice that admits part of the amount. Section 19 does the same for a part payment, provided the payment appears in writing from the payer. A ledger entry for money received from the buyer, matched with the buyer's bank entry, is often enough.
And yes, the Limitation Act applies before the MSME Council too. The Supreme Court said so in Silpi Industries v. Kerala State Road Transport Corporation (2021). The Council won't revive a dead invoice. There's more on this in our guide on the time limit for recovering unpaid dues.
Route 1: the legal notice, and its limits
A legal notice is a formal demand from an advocate. It sets out the invoices, the amount due, the interest claimed and a deadline, usually fifteen days. You don't legally need one before a private recovery suit. Send one anyway. It's cheap and quick, and it often works, especially on buyers who've been ignoring your accounts team but sit up when a lawyer writes. It also pins your claim down on paper, starts the interest argument and draws out the buyer's defence.
But a notice can't force anyone to pay. It doesn't stop limitation running either. And a vague notice that threatens everything at once (police, insolvency, blacklisting) with no real plan behind it just teaches the buyer you aren't ready to act. The notices that work are specific and calm. The next step follows quickly once the deadline passes.
Suing the government is different. A notice under Section 80 of the Code of Civil Procedure, 1908 (CPC) is compulsory, and you have to wait two months after it's delivered unless the court lets you file urgently. What goes into a notice, and how it's served, is on our page about the legal notice for recovering business dues.
Route 2: a commercial suit, summary or regular
If the claim is Rs 3 lakh or more and comes out of an ordinary business deal, it's a commercial dispute under the Commercial Courts Act, 2015. Before you file, you have to apply for pre-institution mediation under Section 12A, unless the suit genuinely seeks urgent interim relief. Mediation can take up to three months, with two more if both sides agree. If the buyer doesn't come, or nothing settles, you file the suit with every document disclosed under Order XI CPC. The buyer then has 120 days at the outside to file its written statement. Miss that and the right is gone.
Faster is the summary suit under Order XXXVII CPC. It's meant for a debt or liquidated demand arising on a written contract, a cheque or something similar. The buyer gets ten days to enter appearance. Once the summons for judgment is served, it has another ten days to ask for leave to defend. If the defence is a sham, leave is refused and you get your decree. If it raises a real issue, the court can still attach conditions, a deposit for instance. Invoices supported by a purchase order and signed goods receipts often qualify. Bare invoices are a closer call.
Go for a regular suit where the buyer has a genuine quarrel about quality, quantity or rates, or where you're also claiming damages that need proving. It's slower. It can still be cut short by summary judgment under Order XIII-A if the defence has no real prospect. Our page on recovering unpaid business dues through court explains the suit itself. For choosing between the two, see the guide on summary versus regular suits.
Route 3: the MSME Facilitation Council
Micro and small suppliers, of goods or of services, get their own route under the Micro, Small and Medium Enterprises Development Act, 2006 (MSMED Act). Start with Section 15. The buyer has to pay within whatever period was agreed in writing, capped at 45 days from acceptance or deemed acceptance, and if no period was agreed it's 15 days. Section 16 then charges a buyer who pays late compound interest, with monthly rests, at three times the bank rate the Reserve Bank of India notifies. You can't contract out of that. Section 18 lets the supplier take the dispute to the MSME Facilitation Council of the supplier's own state. Most people file online through the MSME Samadhaan portal.
The Council tries conciliation first. If that fails, it arbitrates itself or sends the case to an institution. The Act expects an award within 90 days of the reference. Many Councils take longer. In Gujarat State Civil Supplies Corporation v. Mahakali Foods (2022), the Supreme Court held that the Section 18 procedure overrides a private arbitration clause in the contract. And under Section 19, a buyer who wants to challenge the award in court has to deposit 75 percent of it first. That deposit rule is often what gets a large buyer to settle.
It isn't open to everyone. Medium enterprises can't use the delayed payment provisions. Traders run into eligibility questions. If you registered on Udyam only after the purchase order, expect the buyer to object, and since the law on that point isn't fully settled, check the current position before you rely on it. The arbitrationlawyer.in guide on MSME Council or commercial court goes further into the choice.
Notice, suit or MSME Council, compared
| Question | Legal notice | Commercial suit (regular or summary) | MSME Facilitation Council |
|---|---|---|---|
| Who can use it | Any creditor at all | Any creditor. It goes to a commercial court if the claim is Rs 3 lakh or more | Micro and small suppliers registered on Udyam |
| What has to come first | Nothing | Section 12A mediation, unless you're seeking urgent interim relief | Nothing. Conciliation is part of the process |
| Interest | You can claim it in the demand | Contract rate, or whatever the court allows under Section 34 CPC | Compound, with monthly rests, at three times the RBI bank rate |
| If there's an arbitration clause | Makes no difference | The buyer can ask for the dispute to go to arbitration under Section 8 of the Arbitration Act | Section 18 overrides the clause (Mahakali Foods, 2022) |
| How the buyer challenges it | Doesn't arise | Appeal under Section 13 within 60 days | Section 34 petition, only after depositing 75 percent of the award |
| Where it's filed | It's just sent to the buyer | Where the buyer is, or where the cause of action arose (Section 20 CPC) | Before the Council of the supplier's own state |
| Enforcement | Can't be enforced | Decree executed under Order XXI CPC | Award enforced like a decree under Section 36 of the Arbitration Act |
Where cheque bounce and insolvency come in
If the buyer's cheques bounced, you also have a criminal remedy under Section 138 of the Negotiable Instruments Act, 1881, on top of your civil claim. The notice has to go within 30 days of the bank's return memo. The buyer then has 15 days to pay, and the complaint must be filed within a month after that. The criminal case can run side by side with a civil suit or a Council reference. They do different jobs. Our page on running a cheque bounce case with civil recovery explains how they fit.
Insolvency is another animal. For a Section 9 application under the Insolvency and Bankruptcy Code, 2016 you need an operational debt of Rs 1 crore or more, and the buyer mustn't have raised a real dispute before your demand notice. Admission puts the company into a collective process under a resolution professional. You become one creditor in a crowd. Against a solvent company stonewalling an undisputed bill, it can work well. Against one already going under? Rarely. Our guide on when insolvency is better than a recovery suit lays out the tests.
Your paperwork changes the answer
A strong file has a signed purchase order or contract and invoices that match it. It has proof of delivery signed and stamped by the buyer (or work sign-offs), a ledger that ties to the bank statements and, ideally, a balance confirmation. With that, a summary suit is realistic and the MSME Council will move quickly. Even a notice will probably work. The buyer's own lawyer will tell it the defence is thin.
Then there's the in-between file. Invoices and delivery challans exist, but nobody signed a purchase order. Or there's an order, and the only acknowledgment of delivery is a guard's scrawl at the factory gate. Files like that do win. Expect a fight, though, which is why we'd lean towards a regular suit or a well-supported Council reference over a summary suit. Lean on GST records. Your e-way bill, the IRN on the e-invoice, and the buyer's own claim of input tax credit on your invoice all prove that the goods or services actually moved.
A weak file rests on WhatsApp messages and bank transfers. Usually the invoice went out months after an informal order and the buyer never formally received it. An unpaid invoice in that situation is still a debt if you can show the supply. The file isn't hopeless, and claims like this do get recovered. But you'll need to piece the deal together carefully before you pick a forum. Spending money on a weak file before filling its gaps is the commonest way we see businesses lose money on recovery.
So does the buyer
Big companies usually have the money. They also care what their records look like. If you're an eligible MSME supplier, a Council reference with a polite reminder about the 75 percent deposit often settles it. There's more pressure on them, too. Any company holding dues to micro and small suppliers for longer than 45 days must disclose them to the Registrar of Companies in a half-yearly return (Form MSME-1). Separately, its tax deduction for late payments to micro and small enterprises gets pushed back, under the rule introduced as Section 43B(h) of the Income-tax Act, 1961. Your chartered accountant can tell you what the current provision says. Either way, large buyers have reasons of their own to clear MSME dues.
Government departments and public sector undertakings pay slowly. They generally do pay when ordered. Expect a Section 80 CPC notice before any suit against the government, and a long wait for approvals. Our guide on recovering dues from a government department or PSU has more. A small trader or proprietor is a different problem altogether. Will there be anything left by the time you hold a decree? That's the real question, so asset checks and early settlement matter more than the choice of forum.
With a buyer who's clearly in trouble, Advocate B.K. Singh prefers to spend a little on asset checks before spending a lot on proceedings. That means company master data and registered charges on the MCA portal, GST registration status, property records where they're available, and any other recovery cases already pending against the buyer.
Matching the route to your situation
- You're a registered micro or small supplier, the buyer's a solvent company, and the papers are clean. Legal notice, then the MSME Council. The statutory interest and the deposit rule are on your side.
- You're not an MSME, but there's a written contract or signed purchase order and no real dispute. Legal notice, Section 12A mediation, then a summary suit under Order XXXVII.
- Not an MSME, and the buyer is already arguing about quality or quantity. Notice, mediation, then a regular commercial suit. Get ready for evidence.
- There's an arbitration clause and you're not an MSME. Notice, then arbitration. Sue anyway and the buyer can apply under Section 8 of the Arbitration and Conciliation Act, 1996 to have the suit referred to arbitration.
- The buyer's cheques bounced. A Section 138 notice within 30 days of the return memo, plus a civil claim or Council reference for the full dues.
- It's under Rs 3 lakh. Notice, then an ordinary civil suit (a summary suit if it qualifies), or the MSME Council if you're eligible. The Commercial Courts Act doesn't apply at this size.
- A company is refusing an undisputed debt of Rs 1 crore or more. Think about a Section 8 demand notice under the Insolvency and Bankruptcy Code. Keep the suit or the Council as your fallback.
Can you run two routes at once?
Some pairs work. Some don't. A legal notice followed by anything else is standard. A cheque bounce complaint and a civil claim for the same dues run together all the time. What you shouldn't do is file a commercial suit and an MSME Council reference for the same invoices. The buyer will object that you're pursuing one claim twice, and you'll end up defending your choice of forum instead of arguing the debt.
If a buyer owes you on several unrelated contracts, different routes for different contracts can make sense. A Council reference for supplies made after your Udyam registration, say, and a suit for the earlier ones. That needs careful drafting. Neither forum should be asked to decide what the other is deciding.
When a client has already started down one route before coming to us, Advocate B.K. Singh first asks whether switching would be cleaner than carrying on. A half-pursued mediation application, or a reference filed without the Udyam certificate, can sometimes be withdrawn and refiled properly at little cost.
What to do over the next 30 days
Days 1 to 3: make the invoice table
List every unpaid invoice with its date, purchase order, delivery or work proof, GST details and payments received. Mark the oldest one. Mark the last acknowledgment.
Days 3 to 5: check your status, and the buyer's
Dig out your Udyam certificate and note its date. Look up the buyer's legal name, registered office and GST status. For a company, pull its master data and charges from the MCA portal.
Days 5 to 10: send the legal notice
An advocate sends it by speed post and email, claiming principal and interest with a 15-day deadline. If cheques bounced, the Section 138 notice goes within its own 30-day window. Don't let the two get mixed up.
Days 10 to 25: wait, but prepare
While the notice period runs, gather what the chosen forum will need. Export the email and chat threads. Get the Section 63 certificate for electronic records ready.
Day 25 onwards: start the route
File the MSME Samadhaan reference if you're eligible. If not, file the Section 12A mediation application before the District Legal Services Authority. Watch the limitation dates the whole way.
If the buyer answers your notice with a detailed dispute, stop for a few days and think again. A strong reply can push you from a summary suit to a regular one. Or it can make settling look a lot better.
What each route takes in time and money
| Route | Usual time | Main government costs (lawyer's fee not included) |
|---|---|---|
| Legal notice | 2 to 4 weeks | Just postage |
| Section 12A mediation | Up to 3 months, and 2 months more if extended | Rs 1,000 application fee, plus a one-time mediation fee by claim slab that the parties share. It starts at Rs 15,000 for claims of Rs 3 to 10 lakh. Check the current schedule |
| Summary suit | Roughly 6 to 18 months to decree where leave is refused or made conditional | Ad valorem court fee under the state schedule, plus process fee |
| Regular commercial suit | Roughly 18 months to 3 years, often more | Court fee as above, plus evidence costs and certified copies |
| MSME Council | The statute expects an award within 90 days. In practice it's often 6 months to over a year | Usually nothing, or a nominal fee. Check with your state Council |
| Executing the decree or award | Months, sometimes a year or more | Process, attachment and sale expenses |
Papers you'll need, whichever route you pick
- Purchase orders, the contract or the accepted quotation, with the payment terms
- Invoices with GST details, plus e-invoice registration numbers and e-way bills where they apply
- Delivery challans, lorry receipts, signed goods receipt notes, or sign-offs for completed work
- Your ledger for the buyer's account, and bank statements showing what's been paid
- Debit notes, credit notes, TDS certificates, and anything on rate or quantity disputes
- Balance confirmations, emails admitting the dues, and any record of part payment
- Your reminders, the legal notice, proof it was served, and whatever the buyer replied
- The Udyam certificate with its date, if you're claiming under the MSMED Act
- Bounced cheques and their return memos, if there are any
- Your own registration papers, and a board resolution or authority letter for whoever signs
Where each route gets filed
The notice is easy. It goes to the buyer's registered office, and to whichever address you actually did business with. For a commercial suit, Section 20 CPC gives you a choice: the place where the buyer resides or carries on business, or anywhere the cause of action arose wholly or in part, which often means where the goods were delivered or where the money was payable. Delhi splits by value. Up to Rs 2 crore, you file before the District Judge (Commercial Court) of the district that has territorial jurisdiction. Above that, it's the Commercial Division of the Delhi High Court. A revision of that limit has been proposed, so check where it stands on the day you file. Across the border in Noida, Ghaziabad, Gurugram and Faridabad, each district has a designated Commercial Court for these suits.
The MSME Council works differently. You file before the Council of the state where you, the supplier, are located (Section 18(4)), not where the buyer is. Delhi, Uttar Pradesh and Haryana each have their own Council arrangements, and some states run regional Councils, so find out which one covers your district. This rule is a real practical advantage. A Faridabad supplier can claim against a buyer in Pune before a Council in Haryana.
A cheque bounce complaint is filed where the payee's bank branch is, under Section 142(2) of the Negotiable Instruments Act. How all of this fits together in Delhi NCR is on our unpaid invoice recovery page.
An invented example: one supplier, three buyers, three routes
Everything here is invented. Picture a Faridabad auto-parts maker, on Udyam as a small enterprise since 2019, with three accounts gone sour. The first is a vehicle maker in Manesar. It owes Rs 42 lakh, 120 days overdue, and every invoice is supported by a purchase order and a signed goods receipt. The second is a Lucknow distributor who owes Rs 9.5 lakh, most of it billed over two years back, and who has lately begun grumbling about rejected parts. The third is a Bawana proprietor. Rs 3.8 lakh. Two cheques, both bounced last week.
Manesar first. The supplier sends a legal notice. The buyer replies asking only for time, so the supplier files a reference before the Haryana Council. Faced with the statutory interest calculation, and knowing any challenge needs a 75 percent deposit, the buyer's procurement head comes to the conciliation meeting with a payment plan.
Lucknow is about time. The oldest bills are 34 months old, which is close. But eight months ago the distributor sent Rs 1 lakh by bank transfer against the account, and the covering email mentioned the outstanding balance. The supplier replies to each rejection complaint with its inspection reports, then sends a notice and moves quickly with a Council reference. A summary suit in Lucknow, fought over every rejected part, felt like the bigger gamble.
Bawana is simpler. The supplier sends the Section 138 notice within 30 days of the return memo and, separately, a demand for the full Rs 3.8 lakh. To avoid prosecution, the proprietor pays the cheque amounts inside the notice period and agrees in writing to clear the rest in two months. Three buyers. Three routes. Each one picked for a reason.
What to do this week
Make the invoice table. Find your Udyam certificate. Check the buyer's details. Look for the last acknowledgment or part payment, and if any invoice is within six months of the three-year limit, deal with that one first. Send the legal notice once your documents are in order, and settle on a forum before the notice period ends, so you can move the day the deadline passes. If the buyer has simply stopped answering, our page on unpaid invoice recovery explains what comes next.
If you'd rather have the route chosen on your actual papers than on general rules, send your invoices, ledger and correspondence to Advocate B.K. Singh's team through the contact page.
Frequently asked questions
Is a legal notice compulsory before I file a recovery suit for unpaid invoices?
Not against a private buyer, unless your contract says so. Against the government, yes, under Section 80 CPC. In practice we send one almost every time. It often brings payment, and it puts your claim and interest on record.
Can a medium enterprise use the MSME Facilitation Council for unpaid invoices?
No. The delayed payment provisions in Sections 15 to 18 of the MSMED Act protect only micro and small enterprises. A medium enterprise has to go through a legal notice, mediation and a commercial suit, or arbitration if the contract provides for it.
What interest can I claim on unpaid invoices?
The rate agreed in the contract, or printed on invoices the buyer accepted. A registered micro or small supplier can claim compound interest with monthly rests at three times the RBI bank rate under the MSMED Act. In a suit, it's for the court to decide under Section 34 CPC.
How long does the MSME Council take on an unpaid invoice claim?
The Act expects an award within 90 days of the reference. Many Councils take longer, often six months to over a year, depending on the state and the Council's workload. Conciliation comes first, and plenty of cases settle there.
Can I file a summary suit just on invoices?
Sometimes. Courts want a written contract or an acknowledged liquidated debt. Invoices backed by a purchase order, signed delivery receipts or a written acknowledgment of the amount stand a much better chance than bare invoices. If the buyer has disputed quality in writing, a regular suit may be safer.
What if my invoices are nearly three years old?
Look for a signed acknowledgment, or a part payment in writing. Either one restarts limitation. If there's nothing, file the Section 12A mediation application or the MSME Council reference fast, because the clock runs until you do. Don't sit waiting for a reply to your notice if the limit is close.
The buyer's contract has an arbitration clause. Can I still go to the MSME Council?
If you're a registered micro or small supplier, yes. The Supreme Court held in Mahakali Foods (2022) that Section 18 of the MSMED Act overrides a private arbitration clause. If you aren't an eligible MSME, the clause will usually govern.
Is a small invoice under Rs 3 lakh worth chasing?
Often it is, but the route changes. A legal notice is cheap and frequently does the trick. Beyond that, claims below Rs 3 lakh go to the ordinary civil court, not the commercial court, and an eligible MSME can still use the Council. Weigh the cost of proceedings against the amount and the buyer's ability to pay.
