The main difference between an SME IPO and a Mainboard IPO is the size and eligibility of the companies going public. SME IPOs are designed for small and medium enterprises with lower capital requirements, while Mainboard IPOs are meant for larger companies that meet stricter financial, regulatory, and listing criteria.

SME IPOs provide smaller businesses with access to public funding, whereas Mainboard IPOs allow large corporations to raise significant capital from public markets.

What Is an SME IPO?

An SME IPO (Small and Medium Enterprise Initial Public Offering) allows small and growing companies to raise capital by offering shares to the public through SME stock exchange platforms.

In India, SME IPOs are typically listed on:

• NSE SME platform

• BSE SME platform

These platforms were created to help smaller businesses access capital markets without meeting the stricter requirements of mainboard listings.

Many high-growth companies use SME IPOs as a stepping stone toward larger public listings.

Advisory firms such as Lorvet help businesses prepare for SME IPOs by developing fundraising strategies and guiding them through regulatory processes.

Mainboard IPOs typically involve:

• larger capital raises
