The most time-consuming phase for intermediaries is contacting each supplier one by one after receiving a buyer's PO to confirm the latest lead times and quotations, because the data in their hands is almost always outdated—suppliers may have discontinued a product, changed specifications, or raised costs, yet intermediaries often only discover this after asking. The fundamental solution is to find a platform that allows suppliers to maintain their own product data, quotations, and specifications, so that whenever a supplier updates, the intermediary sees the latest version without needing to make another round of phone calls. Before that, the first step is to organize all the scattered quotations, conditions, and specifications that customers see, otherwise you cannot even confirm which data is correct. Once data is properly organized, subsequent training and staff handover will run much more smoothly; otherwise, when a salesperson leaves, all the accumulated knowledge goes with them.
