Amazon is not a pure B2B e-commerce platform, but a mixture of B2C and B2B models.

Amazon mainly provides various goods and services to end consumers (B2C). Users can directly purchase various products on Amazon.

This is the most important and typical model of Amazon, and Amazon earns its main income through this B2C model.

At the same time, Amazon also provides B2B models:

1. Seller model: for corporate sellers and brands, allowing them to open stores and sell products on Amazon.

2. Logistics services: provide logistics information services, warehousing logistics and other B2B services to enterprises.

3. Cloud services: provide cloud computing, intelligent voice and other ICT B2B services to enterprises.

In summary, Amazon mainly operates the B2C model, but also provides some B2B models for enterprises. The two models complement each other and constitute Amazon's overall business.

The B2C model earns the main revenue, while the B2B model plays a supplementary role.

Therefore, Amazon should be more accurately described as a hybrid e-commerce platform with B2C as the main model and B2B as the auxiliary model, rather than a pure B2B platform.

I hope the above explanation can answer your question "Is Amazon a B2B?" If you still have questions, please continue to ask questions.
