Aadhaar Authentication is a digital verification process that links your application to your Aadhaar card using an OTP. While it is highly recommended because it speeds up your approval process without requiring a physical verification of your shop, the department has made biometric and Aadhaar verification mandatory in phases for high-risk profiles to curb fake registrations.

It depends on your business compliance preferences:

• Regular Registration: Ideal for businesses scaling up. You can sell anywhere in India (inter-state), claim full Input Tax Credit (ITC), and issue proper tax invoices to buyers. Returns are filed monthly or quarterly.

• Composition Scheme: Designed for small traders/manufacturers with a turnover under ₹1.5 Crores. You pay a flat, lower tax rate (e.g., 1%) directly from your pocket, but you cannot claim ITC, cannot sell outside your state, and cannot issue regular tax invoices.
