ITFLEX SHIPPING is a specialized application designed for B2B distributors and eCommerce websites, streamlining the shipping process for businesses that prefer to utilize their own shipping accounts. This app caters to the prevalent need among many B2B customers who choose to handle shipping costs through their pre-existing shipper accounts. Through a straightforward process, customers can select the "Collect Option: Apply shipping to my shipper account" and input their account number and chosen service level, which then becomes visible to the administrators. If this option is not selected, it remains hidden, ensuring a clean user interface. The application allows customers to input their shipper details directly into their orders, with these details subsequently reviewed by administrators. This enables administrators to apply shipping charges directly to the customer's shipper account, offering flexibility and control over shipping expenses.
