The MSMED Act's delayed-payment machinery — the 45-day clock, compound interest at three times the bank rate, the Facilitation Council reference — belongs to micro and small enterprises. But enterprises grow. Investment crosses the ceiling, turnover has a good year, and the business that signed the contract as a small enterprise raises its final invoice as something larger. Whether that growth costs the enterprise its statutory protection, and from when, is a question the Udyam classification framework answers with more nuance than most buyers or suppliers assume.
How classification actually works
Since 1 July 2020, MSME classification runs through the Udyam portal on a composite criterion of investment in plant and machinery or equipment and turnover, computed from the enterprise's income-tax and GST filings and updated annually. The ceilings were revised upward with effect from 1 April 2025 — micro to ₹2.5 crore investment and ₹10 crore turnover, small to ₹25 crore and ₹100 crore, medium to ₹125 crore and ₹500 crore — a change that pulled a large band of growing businesses back inside, or further inside, the protected categories. An enterprise's category is therefore not a one-time badge but an annually recomputed status, and litigation increasingly turns on which status held good at which time.
The transition rules
Upward graduation
An enterprise whose figures cross a ceiling does not change category the same day. The framework allows it to continue in its existing (lower) category for a transition period before the higher category takes effect — a buffer designed so that a single good year does not abruptly strip working protections.
Downward movement
An enterprise whose figures fall takes its lower category from the following financial year — the benefit of the smaller category is not available mid-year on a self-declared dip.
The operative details sit in the Udyam notification framework administered by the Ministry of MSME, and the portal's annually updated certificate is the practical evidence of category for any given year.
Pending and future claims: the time-of-supply principle
For the delayed-payment chapter, the decisive question is the enterprise's status when the goods were supplied or services rendered. Three consequences follow. First, claims for supplies made while the enterprise was micro or small survive later growth — graduation does not forfeit accrued statutory interest or an existing Facilitation Council reference relating to those supplies. Second, supplies made after the enterprise became medium fall outside Sections 15 to 18, whatever the Udyam certificate said earlier in the relationship; a running account spanning the transition must be dissected invoice by invoice. Third, registration timing remains the companion rule: supplies made before Udyam registration do not attract the Act's payment protections, so the protected window is bounded on both ends — it opens with registration and closes with graduation beyond "small".
A worked pattern
| Period | Status | Delayed-payment protection |
|---|---|---|
| Supplies before Udyam registration | Unregistered | No MSMED Act claim; ordinary contractual remedies only |
| Supplies while registered micro/small | Protected supplier | Sections 15–18 apply; claim survives later graduation |
| Supplies after graduation to medium takes effect | Medium | No delayed-payment claim for these supplies; contract and general law govern |
Practical counsel
Suppliers: archive the Udyam certificate for every financial year, and map invoices to certificate years before filing a Samadhaan reference — the Council will.
Suppliers approaching a ceiling: plan the transition — long-duration contracts signed as a small enterprise should build the 45-day payment discipline into the contract itself, so that protection survives graduation as a contractual term even when the statute falls away.
Buyers: verify counterparty category year-wise, not once at onboarding; Section 43B(h) income-tax disallowance and the MSMED interest exposure both track the supplier's current category.
Both sides: raise or meet threshold objections before the Facilitation Council at the first opportunity — category and registration timing are jurisdictional gates, and are best fought before, not after, an award.

Frequently Asked Questions
What are the current MSME classification limits?
With effect from 1 April 2025, the ceilings were revised upward: a micro enterprise may have investment in plant and machinery or equipment up to ₹2.5 crore and turnover up to ₹10 crore; a small enterprise up to ₹25 crore investment and ₹100 crore turnover; and a medium enterprise up to ₹125 crore investment and ₹500 crore turnover. Classification is composite — crossing either ceiling moves the enterprise up.
Does crossing a threshold end MSME status immediately?
No. The Udyam framework provides transition periods. On upward graduation, the enterprise continues in its existing category for a defined period before the higher category takes effect; on downward movement, the change likewise operates from the following financial year rather than mid-stream. The Udyam portal recalculates category from ITR and GST data each year.
Which date matters for a delayed-payment claim — supply or filing?
The supplies. The judicially settled position is that MSMED Act protection attaches to supplies made while the enterprise answered the "supplier" definition — a micro or small enterprise with registration. An enterprise that was small at the time of the supplies does not lose its accrued claim merely because it has since grown; conversely, supplies made after graduation to medium do not attract the delayed-payment chapter.
What should contracts say about MSME status?
Both sides benefit from a status representation clause: the supplier declares its Udyam category at signing and undertakes to notify reclassification; the buyer's payment terms are then aligned to the 45-day discipline while the counterparty is micro or small. Invoice-wise records of category at supply save the threshold fight before the Facilitation Council years later.
