Meesho’s reselling model is much like assisted shopping. You, as a customer, buy directly from e-commerce sites like Flipkart or Amazon. But in a reseller model, there’s a third entity between the platform and the customer. The reseller will share a product within their network via WhatsApp or Instagram. If anyone wants to place an order, they will place it after adding their margin, and Meesho will deliver that product to the customer directly,
