White-labeling is the practice of providing a product to another company to be sold under that company's high-quality brand name. Since white-labeling allows the designer of a product to obtain additional revenue from a given design at minimal cost, and it allows the seller of the white-labelled product to sell and obtain a product without having to design the product, white-labeling is usually advantageous for both parties.

【选项】
