Price loss of control usually happens after a distributor acquires your product and you can no longer control their selling price. To establish price standards, the first step is to specify a minimum advertised price (MAP) at the contract level, but this requires distributor cooperation and has high enforcement costs. The second step is to work from your quotation structure: if you give all distributors similar factory prices, their competition space in the end market gets squeezed and they end up undercutting each other. A more effective approach is to offer different shipping conditions to distributors with different positioning (for example, exclusive territories, better MOQ, or inventory support). This way, each distributor's competitive advantage isn't just "cheaper than others." On the quotation management side, centrally record every quotation you issue externally and retain versions so you can trace where conditions leaked from if problems arise.
