A “Brand” or "Product Line" is the umbrella term for a client's end product. It consists of two main elements:
Your fulfillment products (pouches, pamphlets, dispensers, shipping boxes, and stickers (if you have them)).
The Formulary of supplements you are offering to your end-consumer.
This distinction allows you to support a different design look and feel if, for example, you have one brand for women's health and another for men's health - each Brand could have a different set of supplements and a totally different name, look and feel, etc. Each Brand can also support unique supplement names, (noted as a “Client Display Name”), and may have different fulfillment and shipping fees as agreed upon in your MSA.
