Multi-Stage Marketing, often referred to as Multi-Level Marketing (MLM), is a business model where individuals earn income not only from their own sales but also from the sales made by their recruits. This creates a tiered structure, allowing participants to build a network of distributors, which can lead to increased earnings as the network grows. In this system, participants typically pay an initial fee to join and may need to purchase products to sell. While some people find success in MLM, it is important to note that many participants do not earn significant income, and the model can sometimes resemble a pyramid scheme if not structured properly.
