Resellers and Retailers are two companies that purchase and store products, then sell them with a view to earning the purpose of earning a profit. They may be online as well as in brick and mortar stores, or both. They buy from wholesalers and distributors and then resell to businesses or consumers. There are a variety of resellers, but there are two main types which are Dropshipping and Private labeling. Private labeling is where the reseller rebrands a manufacturer’s product by adding their own logo, name and packaging. This kind of reselling practice is common in the technology industry where a computer maker might offer their own hardware, as well as third-party software and accessories.
Another form of reselling is bundling. Bundling occurs when a seller mixes similar products from different companies to make a package that is attractive. A reseller, for example might buy digital cameras, memory cards and Photoshop Lightroom software made by various manufacturers to create a kit to help new photographers begin their journey into digital photography.
Retailers typically buy in bulk from wholesalers or distributors, and then sell the items at a higher price to consumers. They also sell through marketplaces on the Internet like eBay or Amazon. Retailers offer a variety of added value services, such as customization and technical support. They can also add additional charges, like shipping and handling charges. For example, Home Depot might charge more than Walmart for barbecue grills since it has a physical store and can handle logistics such as storage and distribution.
