Udyam vs Udyog Aadhaar

Udyam and Udyog Aadhaar are two generations of the same idea — registering as an MSME. Udyam is the current system; Udyog Aadhaar was the earlier one it replaced. The shift was more than a rename.

What changed

Udyog Aadhaar was the earlier, largely self-declared MSME registration. Udyam replaced it with a system tied more closely to official data, linking the registration to the enterprise's PAN and other records rather than relying on declaration alone.

The move was aimed at making MSME registration more reliable and harder to misstate, so the register reflects genuine enterprises.

Why registering on the current system matters

The protections that matter — including the delayed-payment machinery for micro and small suppliers — run off being properly registered as an MSME. Relying on an old registration where the current system expects Udyam can leave a business unable to use those protections when it needs them.

The specifics of migration and current requirements are set by the rules, so a business should confirm its registration is current rather than assume an old one still counts.

How Lekha uses registered status

Lekha's 45-day clock is meaningful where a supplier is a registered micro or small enterprise, so current MSME registration is what makes the overdue signal relevant.

Lekha records what your documents say and tracks the money on both sides — what you owe and what you are owed. It records and tracks; it does not replace your accountant.
