In one sentence
To recover an unpaid business invoice in India you can use a collection agency, a demand notice, MSME Samadhaan, a Section 138 complaint, a commercial suit, arbitration or a Section 9 insolvency petition. Which one fits depends on the amount, the documents you hold, whether a cheque bounced, whether you are a registered micro or small supplier, and whether the debt is disputed.
Key takeaways
- Start with the least expensive route the evidence supports. A demand notice comes before almost every legal route, and many accounts settle at that point.
- MSME Samadhaan is open only to micro and small suppliers registered on Udyam at the time of supply. A buyer challenging the Council's award must first deposit 75% of it.
- Section 138 applies only where a cheque has bounced, and its deadlines are strict: notice within 30 days of the bank's return memo, 15 days for the drawer to pay, and the complaint within one month after that.
- IBC Section 9 is not a collection tool. It needs a default of ₹1 crore or more, fails on a genuine pre-existing dispute, and starts an insolvency process for every creditor.
- A commercial suit of ₹3 lakh or more must go through pre-institution mediation under Section 12A first, unless it seeks urgent interim relief.
