International distribution channel functions perform many important roles: 1. They provide information to manufacturers about market developments like changes in customer demographics or new competitors. 2. They help maintain price stability in the market by absorbing price increases or keeping their own overheads low. 3. Middlemen promote products in their territory through sales programs to build customer traffic. 4. Additional functions include financing manufacturers' operations, taking title to goods to diffuse risk, helping with production, matching supply and demand, standardizing transactions, and matching buyers and sellers. Effective management of relationships between channel members benefits all parties.
