When we talk about Marketplace, we mean a platform where various companies can sell their products. It does not depend on a single seller, there are several in the store. There are different types of shipments and payment methods that users can access.
In the case of online stores, they are platforms dedicated to a single business, selling their products exclusively. This allows for better control of customers and their behavior to improve sales/marketing strategies and promotes market segmentation.
Whatever your choice, it is important that a business has an e-commerce solution that allows it to continue marketing its products even when there are circumstances that we do not control that are affecting the market.
