It covers:

• Online retail stores (like Amazon, Meesho, Myntra)

• Service bookings (consultations, salons)

• Subscription models (Netflix, Spotify, beauty boxes)

If money is exchanged over the internet, it falls under E-commerce.

1. B2C (Business to Consumer)

The most common model.

Ex: You buy a dress from Myntra or a phone from Amazon.

3. C2C (Consumer to Consumer)

Individuals selling to individuals through platforms.
