In short. Supply disputes are fights about goods. The buyer sends them back, knocks money off for quality or shortage, or just stops paying, and manufacturers, traders and distributors end up on both sides of that. Above Rs 3 lakh, it's a Commercial Court case, after mandatory mediation. A fought case takes one to three years. Many settle sooner. Your first move is to put your demand or objection in writing, then collect the purchase order, the delivery proof and every email you have about quality.
Is this your situation?
- The buyer ran half the consignment through his production line. Now he says the entire lot was defective.
- Payments do come in, but each one is short, with a debit note attached that you never agreed to.
- You sent a consignment back because the quality was poor, and the supplier wants the full price anyway.
- The goods came late, or short, or nothing like the sample. Your own customer cancelled because of it.
- The purchase order was cancelled after the goods had already been made to the buyer's drawing.
- Your ledger shows a balance. The buyer won't sign the confirmation.
- You're a registered micro or small supplier, and the 45 days ran out long ago.
What counts as a supply dispute
Any disagreement between businesses over goods sold. Did the right goods arrive? Were they good enough, and on time? And how much is still owed? The contract itself might be a signed supply agreement, a purchase order accepted by email, a rate contract, or nothing more than years of invoices and payments. Each of these is a contract for the sale of goods. Whatever the parties forgot to write down, the Sale of Goods Act, 1930 fills in.
Hardly any of these start as a legal argument. They start with a phone call from the buyer's stores saying the material failed inspection. Or a payment lands lighter than expected, with a debit note stapled to it. By the time the file reaches us, there are usually six months of emails, two versions of the ledger, and a heap of goods sitting in somebody's godown. The question underneath barely changes. Who carries the loss for these goods, and what paper proves it?
We act for both sides, so this page does too. Suppliers will find how to recover the price and handle quality objections that surface late. Buyers will find how to reject goods properly and claim damages. If it's just an unpaid bill and nobody's arguing about quality, go to our page on unpaid invoice recovery. It's the shorter road.
The Sale of Goods Act sections that decide most of these cases
Sections 12 and 13: condition or warranty
A condition is a term so basic that breaking it lets the buyer reject the goods. A warranty matters less. Breach of a warranty gets you damages, nothing more. Then Section 13 adds a sting: once the buyer has accepted goods under a contract that isn't severable, a breach of condition can only be treated as a breach of warranty. Put plainly, accept the goods and you've usually lost the right to send them back.
Sections 15, 16 and 17: description, quality and sample
Goods sold by description have to match it. If the buyer tells the seller the purpose and relies on the seller's skill, there's an implied condition that the goods are reasonably fit for that purpose. Buy by description from a seller who deals in those goods and they must be of merchantable quality. In a sale by sample, the bulk has to match the sample. The contract can cut these implied terms down, though. That's why the small print on the purchase order matters so much.
Section 37: wrong quantity
When the seller delivers short, the buyer may reject the whole lot or keep it and pay for what actually came. When it delivers too much, the buyer may keep the contracted quantity and refuse the excess, or refuse everything. Goods of a different description mixed in can be rejected on their own.
Sections 41, 42 and 43: examination, acceptance and rejection
The buyer gets a reasonable chance to examine the goods. Section 42 deems acceptance in three ways. He says he accepts. He does something inconsistent with the seller still owning them, like using, processing or reselling them. Or he keeps them past a reasonable time without telling the seller he's rejecting. Section 43 is kinder to buyers than most people think. A buyer who rightly rejects doesn't have to send the goods back. Telling the seller in writing that he refuses them is enough.
Sections 45 to 61: remedies
An unpaid seller has a lien on goods he still holds (Section 47), can stop goods in transit if the buyer becomes insolvent (Section 50), and can sometimes resell (Section 54). He can sue for the price (Section 55). Or for damages if the buyer won't accept delivery (Section 56). The buyer, for his part, can sue for damages for non-delivery (Section 57), and for breach of warranty can either set the loss off against the price or sue for it (Section 59). Section 61 keeps claims for interest and special damages alive.
Suppliers: the buyer won't pay and says the goods were bad
Acceptance is usually your best card. Maybe the buyer took delivery, signed the challan or goods receipt note, held the goods for weeks, used them in production or sold them on. Section 42 then treats the goods as accepted. A quality complaint that first appears after your legal notice, or months after delivery, counts for far less than one sent in writing a few days after the goods arrived.
Watch what the buyer did, not what he's saying now. Repeat orders after the supposed defect. Later invoices paid without a murmur. His own ledger, or a year-end balance confirmation, showing the whole amount as payable. Every one of these tells the court the goods were fine. Every one can go into the plaint, with the document attached.
A real defect is another matter. If the buyer complained in writing within the inspection period, set the goods aside and offered them back, he may well have rejected them properly. Then your claim depends on whether the goods actually met the specification. A joint inspection or an independent lab report, done early, is worth more than a year of arguing. When Advocate B.K. Singh picks up a supplier's file, he reads the buyer's first complaint before he looks at a single invoice. The date and wording of that complaint usually tell you which way the case will lean.
Buyers: how to reject goods and keep your rights
Reject clearly, quickly, and in writing. Write to the supplier the moment inspection turns up the problem. Name the consignment, the invoice and the fault. Say in so many words that you reject the goods and are holding them at the supplier's risk. Then leave them alone. Don't use them, process them or mix them with good stock. A buyer who complains about material while feeding it into the plant is often treated as having accepted it.
Lock down the evidence before anything changes. Dated photographs. Samples drawn in front of the transporter or the supplier's man. Your incoming inspection report. And, where the money justifies it, a report from an independent testing lab. If the contract names a test method or standard (a BIS standard, a drawing number, an approved sample), test against exactly that. Your own idea of quality doesn't come into it.
Found a hidden defect only after accepting the goods? You haven't lost everything. Section 59 lets you set the loss off against the unpaid price, or sue for damages. What you can't comfortably do is return goods you've been using for months. Claims for lost orders, or penalties you paid your own customer, are possible too. But you'll have to show the supplier knew, when the contract was made, that this kind of loss was likely. That's the Section 73 test under the Indian Contract Act, which our breach of contract page explains.
Patterns that keep turning up
- Debit notes nobody agreed to. The buyer pays the invoice less a cut for rate difference, late delivery or rejection, and raises a debit note the supplier never accepted. The supplier sues for the balance. It's for the buyer to prove the contract let him deduct.
- Rejection after use. The goods have been processed or sold, and the complaint shows up only when payment falls due. Section 42 tends to help the supplier here.
- Short supply and transit loss. Less material reached the buyer's gate than the invoice shows. The lorry receipt, the weighment slips and the e-way bill decide who takes the loss, and whether the transporter can be claimed against.
- Penalties for late delivery. There's a penalty clause in the PO and the buyer has deducted it. Under Section 74 of the Contract Act, courts allow only reasonable compensation up to the stated figure. And delay caused by the buyer sitting on approvals doesn't count against you.
- Cancelled orders. The buyer cancels after the goods have been made to its specification. The supplier can claim damages for non-acceptance under Section 56, less whatever it gets by selling the goods elsewhere.
- Running account fights. Years of supplies and part payments, two ledgers that refuse to agree, and a balance nobody accepts. Reconcile properly before anyone files.
MSME suppliers: extra protection you may already have
If you're registered as a micro or small enterprise under the MSMED Act, 2006, you're better placed than an ordinary supplier. Section 15 makes the buyer pay within the agreed period, which can't exceed 45 days from acceptance or deemed acceptance, or within 15 days if nothing was agreed. Pay late, and Section 16 adds compound interest with monthly rests at three times the bank rate notified by the RBI. Section 17 makes the buyer liable for the price and that interest both.
Section 18 lets you take the dispute to your state's Micro and Small Enterprises Facilitation Council. The council tries conciliation first, then arbitrates or sends the matter to arbitration. Delhi, Uttar Pradesh and Haryana each have their own, and claims are filed online on the MSME Samadhaan portal. Buyers dislike one part in particular. To challenge the council's award, they must first deposit 75 percent of it (Section 19). That cools a buyer's enthusiasm for delay.
Two cautions. One, the protection generally covers supplies made after you registered, not before. Check the date on your Udyam certificate against your invoice dates. Two, a large buyer that took GST input tax credit on your invoice has to reverse it if it doesn't pay you within 180 days, and income tax rules also tie the buyer's deduction to paying micro and small suppliers on time (check the current provision). Get these points right in a notice and a buyer's accounts team often moves faster than it would for a threat of litigation. Whether you go to the Facilitation Council or file a money recovery suit in the Commercial Court depends on the amount, your evidence, and how fast you need security over the buyer's assets.
From the first complaint to a decree
This is the usual path. Plenty of cases stop at step 3 or step 4.
Gather every paper now
Pull together the purchase order and every invoice, delivery challan, lorry receipt, goods receipt note, inspection report, debit note and payment advice. Export the email threads and WhatsApp chats with the dates intact. Match your ledger against the buyer's last balance confirmation. Do it before you write a word.
Put it in writing, properly
Each side has its own letter to send. A seller sends a demand for the price with the statement of account, a buyer a rejection or claim notice with the defect evidence. A well-drafted legal notice sets out the contract, the breach and the amount with interest. Keep it honest. Don't overstate anything you'll have to prove later.
Try to agree the numbers
Most of these fights are about a percentage, not all or nothing. A joint inspection, a fresh test at a neutral lab, or the two accounts teams sitting down together settles a lot of them. Write down any settlement, with a payment schedule.
Pre-institution mediation
Unless you need urgent interim relief, Section 12A of the Commercial Courts Act makes you apply for pre-institution mediation through the District or State Legal Services Authority. Three months is the limit, extendable by two months if both agree. If the buyer doesn't turn up, you get a non-starter report. Then you file.
File the commercial suit
Your plaint carries a statement of truth, every document in your power and a list of documents, as the amended Order XI requires. A seller with a written contract or invoices for a fixed sum can file a summary suit under Order XXXVII. A damages claim goes as a regular commercial suit.
Defence and documents
The defendant gets 30 days for its written statement, stretchable to an outside limit of 120 days from service of summons. In a summary suit it must appear within 10 days, and then seek leave to defend within 10 days of the summons for judgment. Admission and denial of documents comes next.
Case management, evidence, judgment
At the case management hearing the court frames issues and sets a timetable for evidence affidavits and cross-examination. If one side has no real case, the other can ask for summary judgment under Order XIIIA. Final arguments follow the evidence.
Execution
An unpaid decree is enforced under Order XXI by attaching bank accounts, receivables, stock or property. The Supreme Court's directions in Rahul S. Shah v. Jinendra Kumar Gandhi (2021) say execution should ordinarily be decided within six months.
Sometimes an insolvency petition comes up instead, where the buyer is a company owing Rs 1 crore or more and the debt isn't disputed. That's NCLT work. A genuine quality dispute that existed beforehand will usually sink it. So don't treat it as a replacement for a suit when quality is in issue.
What each stage costs and how long it takes (general guidance)
| Stage | Costs apart from lawyer's fees | Usual time |
|---|---|---|
| Notice and reconciliation | Courier and postage; a lab testing fee if you get a fresh test done | 2 to 6 weeks |
| Section 12A mediation | A one-time fee to the Legal Services Authority, split equally and fixed by claim-value slabs under the 2018 Rules; check the authority's current table | Up to 3 months, plus 2 months more if extended |
| MSME Facilitation Council (if you choose it) | No court fee; you file on the Samadhaan portal | The Act says 90 days for the award; it often takes longer |
| Filing the commercial suit | Ad valorem court fee on the claim under state law (Delhi, UP and Haryana each have their own schedule); check the current schedule before you file | 1 to 3 weeks to draft and file |
| Summary suit, up to leave to defend | Process fee and service costs | 3 to 9 months, depending on service and listing |
| Written statement and documents | Costs if the defendant is allowed to file late | 30 days, outer limit 120 days from service |
| Evidence and arguments | Lab or technical witness costs; costs imposed for adjournments | 1 to 2 years in most district commercial courts, varying from court to court |
| Appeal under Section 13 | Court fee on the memorandum of appeal, as state law fixes it | Must be filed within 60 days; hearing time varies |
| Execution | Process fees for attachment and sale | Meant to be decided within 6 months ordinarily; often longer in reality |
Which court hears it: value and place
Sale of goods is named outright. Section 2(1)(c)(xviii) of the Commercial Courts Act covers agreements for the sale of goods, and ordinary dealings between merchants and traders fall under Section 2(1)(c)(i), so at a specified value of Rs 3 lakh or more the suit goes to a Commercial Court. Watch the interest. For a money claim, Section 12 counts the principal plus interest up to the filing date, which means an invoice for Rs 2.6 lakh that's two years overdue can tip over the line.
In Delhi, commercial suits up to Rs 2 crore go to the District Judge (Commercial Court) at the district complexes: Saket, Tis Hazari, Karkardooma, Rohini, Dwarka or Patiala House, depending on the district. Bigger suits go to the Commercial Division of the Delhi High Court. A proposal to raise the district limit is under consideration. Check the current figure before you file. In Ghaziabad, Gautam Buddh Nagar, Gurugram and Faridabad, you file in the court designated as Commercial Court for the district, and appeals go to the Allahabad High Court or the Punjab and Haryana High Court. Our page on which commercial court hears your case has more.
Place depends on Section 20 of the Code of Civil Procedure. You can sue where the defendant carries on business, or wherever part of the cause of action arose, which might be where the order was accepted, where delivery was due or where payment was due. Lots of purchase orders carry an exclusive jurisdiction clause. Courts generally respect it if it picks one of the courts that already had jurisdiction and both sides agreed. A line printed at the foot of your own invoice is shakier ground than a clause in a PO the buyer signed.
Summary suit or regular suit for the price?
If you're suing for the price on signed invoices, an accepted purchase order or a written contract, Order XXXVII is often available. The buyer can't defend as of right. It has to apply for leave and show a real, triable defence. Under the Supreme Court's tests in IDBI Trusteeship Services v. Hubtown (2016), a defence that's plausible but doubtful may get leave only on terms, for example a deposit of part of the amount.
Quality defences are the commonest reason leave gets granted, and a buyer holding a dated rejection letter and a lab report will probably get it. If all the buyer holds is a debit note raised after your notice, leave may be refused. Or a deposit ordered. So the buyer's papers matter as much as yours when you choose the suit. Our guide on summary suit versus regular suit lays out the trade-off.
A buyer's claim for defective goods, lost profit or a penalty paid downstream isn't a liquidated sum. It goes as a regular commercial suit. So does a seller's damages claim over a cancelled order. Even inside a regular suit, Order XIIIA summary judgment is available where the other side's case has no real prospect. That's handy when the defence is thin but the claim isn't a fixed debt.

How long you have to file
Most claims for the price of goods have a three-year limit under the Limitation Act, 1963. When the three years start depends on how you dealt. Goods sold and delivered with no fixed credit period fall under Article 14, and time runs from delivery. With a fixed credit period, Article 15 starts the clock when that period ends. And where both sides kept a mutual, open and current account with reciprocal demands, Article 1 gives three years from the close of the year in which the last item was admitted or entered.
Two rules rescue a lot of older claims. The first is Section 18: a written acknowledgment of the debt, signed by the buyer before time runs out, starts a fresh three years, and a balance confirmation, a signed ledger or an email admitting the amount can all count. The second is Section 19. A part payment made before expiry, shown in writing, restarts time too. Timing matters. An acknowledgment that comes after limitation has expired won't revive the claim under Section 18, though it may support a fresh promise to pay under Section 25(3) of the Contract Act.
Buyers get three years too. A damages claim for defective goods usually runs from the breach, and whichever side you're on, the time spent in Section 12A mediation is left out of the count. Our guide on the time limit to recover unpaid dues has worked examples.
Interest on unpaid goods
Begin with the contract. If the PO or supply agreement fixes a rate for late payment, courts usually apply it, unless it's really a penalty. A rate printed only on the seller's invoice is less certain. It helps if the buyer took a long run of invoices on those terms and paid without protest. Don't bank on the full printed rate, though.
Where there's no agreed rate, Section 61 of the Sale of Goods Act keeps your right to interest alive, and Section 34 of the Code of Civil Procedure lets the court award interest from the date of the suit. In commercial matters the court can go above 6 percent a year, though ordinarily not beyond the contract rate or what nationalised banks charge on loans. Registered micro and small suppliers have the MSMED Act rate, three times the bank rate compounded monthly. That's usually far higher than anything else on offer.
Spell out the interest claim in the plaint. Rate, basis, period, and a calculation sheet attached. Ask vaguely for 'interest at a reasonable rate' and you'll tend to get a modest award, which is a poor return on a claim you've otherwise proved well. Our guide on interest on unpaid dues runs through the options.
Keeping the money, or the goods, safe while the case runs
A seller who's worried the buyer will empty its accounts or sell off stock before judgment can apply for attachment before judgment under Order XXXVIII Rule 5. The court will want evidence that the defendant is about to dispose of or remove property to defeat a decree. That it owes you money isn't enough. Recent transfers, a factory shutting down, a sudden change of business address. Facts like these help.
When the fight is about the goods themselves, Order XXXIX Rule 7 lets the court order them preserved or inspected, or samples taken. That's useful when rejected material is lying in the buyer's warehouse and might deteriorate. In bigger stock disputes, the court can appoint a receiver under Order XL to hold or sell the goods and keep the money in court. Urgent relief of this kind also lets you file without waiting for mediation. The urgency has to be real, and it has to show on the face of the plaint.
An unpaid seller still holding the goods can keep them under the Section 47 lien and needn't deliver until paid, unless credit was agreed. A buyer who paid an advance and fears the supplier won't deliver can ask the court to stop a sale of identified goods to third parties. Courts are wary, though, where damages would do the job.
Where things usually go wrong
Sellers most often go wrong by leaving debit notes unanswered. Two years on, every unchallenged debit note looks like a deduction you accepted. Answer each one in writing. One line is fine. The second mistake is suing for the gross invoice value when your own ledger shows part payments and credit notes. An overstated plaint hurts your credibility. It also makes leave to defend easier for the buyer.
Buyers usually go wrong with a vague complaint. 'Material not up to the mark', without the invoice number, the defect and a test result, isn't a rejection. The other trap is carrying on using the goods while disputing them. And buyers forget that a claim for lost orders needs proof they told the supplier about the end use when the order was placed.
By the time a supply case reaches Advocate B.K. Singh after talks have broken down, the documents that decide it are often tiny ones. A goods receipt note stamped with no remarks. An inspection report signed by the buyer's own staff. A WhatsApp message saying 'material received, ok'. Both sides should hunt for these before deciding how hard to fight.
Traders, manufacturers, MSMEs and large buyers: how it differs
Traders and distributors mostly work on running accounts with lots of small invoices. For them, the real work is reconciliation and limitation. Manufacturers who supply to specification get drawn into quality and drawing disputes, where technical evidence counts as much as the accounts. Registered micro and small enterprises have the MSMED Act route and its interest, which large suppliers don't. Startups and online brands buying from contract manufacturers are usually the buyer, with claims for defective batches, delayed launches and customer returns.
Big companies tend to run on vendor codes, portal-generated purchase orders and standard terms that lean their way. Long inspection windows. Their own jurisdiction clause. Caps on what a supplier can claim. Read those terms before you assume the Sale of Goods Act defaults apply. Many also include an arbitration clause, in which case the dispute may have to go to arbitration and not to a suit.
Geography counts too. A Ghaziabad manufacturer supplying a buyer in Gurugram may get to choose the forum, depending on where the order was accepted and where payment was due. UP and Haryana have separate court fee schedules and separate MSME Facilitation Councils, and the place you file can change both cost and time. Pick the forum on purpose. Not out of habit.
An invented example: the rejected batch
None of this happened. It's an illustration. A Noida packaging manufacturer supplies printed cartons worth Rs 18 lakh to a Delhi food company over four months. The buyer pays Rs 11 lakh. Then it sends a debit note for Rs 7 lakh, claiming one batch had printing defects. Its first written complaint comes two months after that batch was delivered, by which time the cartons had been filled and shipped to retailers.
The manufacturer disputes the debit note in writing, sends a legal notice with its ledger and the signed goods receipt notes, and applies for Section 12A mediation. At the mediation, the buyer produces photos of a few hundred faulty cartons. Not the whole batch. On those figures the defect touches a small part of one batch, and the deemed acceptance argument on everything else is strong. They settle close to the balance minus the value of the faulty cartons, payable in two instalments. The settlement is recorded under the 2018 Rules, so it can be enforced like an arbitral award. Had mediation failed, the manufacturer could have filed a summary suit for the balance and asked the court to make any leave conditional on a deposit.
What to do this week
If you're owed money, reconcile your ledger, find the buyer's last written acknowledgment and work out how much limitation you have left. Dispute any debit note in writing. If you're a registered micro or small supplier, put your Udyam date next to your invoice dates. If you're the one who rejected goods, send a clear written rejection today, stop using the material, and have it tested against the contract specification.
Whichever side you're on, don't rush to file. Check whether mediation is required, whether there's an arbitration clause, and which court has jurisdiction. Those checks head off most procedural trouble. If a suit or notice has landed on you instead, our page on defending a commercial suit sets out your deadlines.
You can send your purchase orders, ledger and quality correspondence to Advocate B.K. Singh's team through the contact page, and have them looked at before you decide anything.
Frequently asked questions
Can a buyer reject goods after using them?
Usually not. Section 42 of the Sale of Goods Act treats using, processing or reselling goods as acceptance. After that, the buyer can generally claim damages but can't reject. If a hidden defect turns up later, the loss can still be set off against the price under Section 59.
How long does a buyer get to reject defective goods?
A reasonable time after a fair chance to examine them, unless the contract fixes an inspection period. What's reasonable depends on the goods. Perishables need days; complex machinery may justify longer. A written rejection soon after inspection is much safer than a late complaint.
The buyer cut my payment with a debit note. Can I get that money back?
Yes, if the contract gave the buyer no right to deduct. Write back disputing the debit note, and put the balance into your demand and, later, into your suit, so the buyer is left having to prove the defect, delay or rate difference it's relying on.
Is a supply dispute a commercial dispute?
Yes. Section 2(1)(c)(xviii) of the Commercial Courts Act, 2015 lists agreements for the sale of goods. If your claim, with interest up to filing, is Rs 3 lakh or more, it goes to a Commercial Court, and you'll generally need Section 12A mediation first.
Can I file a summary suit for unpaid goods?
Often, if you have a written contract, an accepted purchase order or invoices for a fixed amount. The buyer then has to seek leave to defend. A buyer with dated quality complaints and test reports will probably get leave, sometimes on condition of a deposit.
What's the time limit to sue for the price of goods?
Usually three years. It runs from delivery if no credit period was fixed, from the end of the credit period if one was, and from the close of the year of the last entry for a mutual open account. A signed acknowledgment or a part payment before expiry restarts it.
Should an MSME supplier go to the Facilitation Council or to court?
It depends. The amount, your evidence and whether you need urgent security over the buyer's assets all matter. The council gives high statutory interest, and the buyer must deposit 75 percent before it can challenge the award, while a Commercial Court suit gets you attachment before judgment and other interim orders.
The rejected goods are still in the buyer's warehouse. What happens to them?
They stay put. A buyer who rightly rejects doesn't have to send them back, though he has to keep them reasonably and let the seller collect them. Either side can ask the court for preservation, inspection or sampling under Order XXXIX Rule 7, and in bigger disputes the court may appoint a receiver to hold or sell the stock.
