B2B Storefronts Struggle to Convert Inquiries into Orders Due to Quote Disconnect

This breakdown prevents the sales team and warehouse from reliably executing the transaction. A proposed solution involves maintaining a connected workflow from the initial buyer request through the final quote, confirmed order, and fulfillment. This requires integrating the storefront, CRM, and ERP systems to preserve data continuity at each stage.
