Demand chain business modelA demand chain is composed of the enterprises that sell a business's goods or services. For example, a demand chain may be composed of buyers who initiate the sales transaction, the resellers who sell the manufacturer's goods, and the manufacturer who creates the goods. Or a demand chain may be composed of the resellers who sell a manufacturer's goods, the manufacturer who makes the goods, and the distributors who supply the manufacturer's goods to the resellers.
