Correctly Calculate Shipping
Per my detailed support ticket (#97099) with your staff this week, your system returns incorrect rates from Fedex, DHL and UPS because it does not send across package dimensions to these carriers. Hence, multiple quantities of a package where the total shipped package size exceeds the 5,184 cubic inch dimensional weight limit is being undercharged which means that we either need to ask the customer for more money or eat the shipping charge.
Please refer to the support ticket for the background and full explanation. This problem potentially affects every 1SC client and our customers.
