B2C is easy since you are offering directly to end users or consumers. Since consumers tend to find what they want themselves, this kind of business becomes easy to operate and run compared to B2B where you have to offer to other businesses.
Each model has its challenges and benefits. B2C requires creativity to attract a large number of customers, while B2B requires long-term relationships with other businesses. B2C is easy to start, but competition is fierce. B2B brings in high revenue per deal, but the sales process is long. Choose according to your capabilities and goals.
