In short
- An unpaid invoice is usually a claim for money due under a contract, written or not. The general time limit to sue is three years.
- If you are a micro or small enterprise supplying goods or services, the MSMED Act, 2006 limits payment terms to 45 days and lets you claim compound interest at three times the RBI bank rate for late payment.
- Micro and small suppliers can take payment disputes to the MSE Facilitation Council, now filed online through the MSME ODR portal.
- For commercial disputes worth ₹3 lakh or more, a suit usually can't be filed until pre-institution mediation has been tried, unless urgent interim relief is needed.

02What the law says
If you supplied goods or services and weren't paid, you can recover the money through a civil claim based on the contract, purchase order, invoices and correspondence.
Under the MSMED Act, 2006, a buyer must pay a micro or small enterprise supplier on or before the agreed date. The agreed period can't be more than 45 days from the day the buyer accepted, or is deemed to have accepted, the goods or services. Where there's no agreement, payment is due within 15 days (Section 15). If the buyer pays late, it must pay compound interest with monthly rests at three times the bank rate notified by the RBI (Section 16). Either party can refer the dispute to the Micro and Small Enterprises Facilitation Council (Section 18). The Council first tries to settle it, then decides it by arbitration or refers it to arbitration. The Supreme Court has held that the Limitation Act doesn't apply to the settlement stage but does apply to arbitration. Whether you count as a "supplier" can depend on your registration status. Courts have ruled on this in different ways.
The MSMED (Amendment) Act, 2026 adds timelines for the Council: mediation within 90 days, arbitration referral within 30 days after a failed mediation, and an award within 90 days of pleadings. It also lets awards be recovered as arrears of land revenue and requires a buyer who challenges an award to deposit 75% of it. These provisions take effect only from dates the central government notifies, so whether they apply yet can be checked in the Gazette. Separately, income-tax law limits when a business buyer can claim a tax deduction for amounts owed to a micro or small enterprise that it pays late.
For commercial disputes of ₹3 lakh or more, Section 12A of the Commercial Courts Act, 2015 requires pre-institution mediation before a suit, unless the suit asks for urgent interim relief. The Supreme Court has held this is mandatory.
03Where you can go
- The client, in writing. A reminder with the invoice, the due date and the amount creates a record.
- Legal notice. A formal demand, usually sent through an advocate.
- MSE Facilitation Council, through the MSME ODR portal (odr.msme.gov.in (opens in new tab)), for micro and small enterprises.
- Pre-institution mediation through the Legal Services Authority, for commercial disputes of ₹3 lakh or more.
- Commercial court or civil court. A recovery suit, or a summary suit under Order XXXVII of the Code of Civil Procedure where the claim is based on a written contract.
- Arbitration, if the contract has an arbitration clause and the MSMED route isn't being used.
04How it usually works
- 01
Suppliers usually put together the purchase order or contract, invoices, delivery proof, acceptance emails and the ledger.
- 02
A written reminder is sent, then a legal notice if needed.
- 03
A micro or small supplier can file on the MSME ODR portal. The Council tries to settle the dispute, then arbitrates if needed.
- 04
Otherwise, for a commercial claim of ₹3 lakh or more, pre-institution mediation is tried first. If it fails, a suit is filed.
- 05
The court or Council decides, and the order or award can then be enforced.
05Time limits
- 45 days: maximum agreed payment period for buyers of goods or services from micro and small enterprises. 15 days where nothing was agreed.
- Three years: the general time limit for a suit to recover the price of goods or work done, usually from when payment fell due.
- Three months: for pre-institution mediation under the Commercial Courts Act, extendable by two months with consent. This time doesn't count towards the limitation period.
06Documents to gather
- Contract, purchase order or email agreeing the work and price
- Invoices, and GST invoices or e-way bills where relevant
- Delivery challans, proof of delivery, or completion and acceptance emails
- Account statement or ledger showing what's outstanding
- Udyam registration certificate, if you're a micro or small enterprise
- Reminders, replies and any message where the client admits the dues
07Common questions
08Questions to ask an advocate
If you speak to an advocate, these questions can help make the conversation useful.
- Do I qualify as a micro or small "supplier" for this contract?
- Should I use the Facilitation Council, arbitration under my contract, or a court?
- Is my claim within time, and has anything restarted it?
- Is my dispute a "commercial dispute", and does pre-institution mediation apply?
