Why won't channel partners cooperate even when the price is low enough?

Low price does not equal profit for channel partners. Besides earning the buy-sell margin, channel partners must bear actual costs such as warehousing, logistics, customer service, and returns handling. If the manufacturer's factory price is too compressed, it may seem like a concession, but the gross margin left for channel partners is often insufficient to cover these expenses. Channel partners naturally lack motivation to actively promote the product and may instead push competing brands with better margins. What truly encourages channel partners to cooperate is a quotation structure that clearly accounts for their service costs and reasonable profit, so they can see at a glance that dealing with your brand is "worthwhile." Therefore, pricing design should be built on the actual needs of channel roles, not simply a factory cost plus a shipping price.
