How can I set conditions of what shipping price to show my customer depending on dimensional shipping and the weight of the package?
something like what Table Rate Shipping for WooCommerce does, in which if the dimensional weight is bigger than the product weight the shipping price changes.
if it is not possible using default Shopify options, is there a plugin that covers that part (no matter if payment required)?
I have been looking and can not find anything for dimensional shipping. You would think a company the size of Shopify would have this as #1 on the list as all shippers have moved to dimensional weight shipping. If you find anything please let me know.
For others that might not know what dimensional shipping is.
We need to be able to enter the length, Width and height along with a weight for UPS, Fed X and others to correctly calculate the shipping amount. As an example there could be a product that sells for only $20 that is 3 pounds but the box size is 50*8*12. In this case the freight will be $43 via UPS ground. But if I feed the system only the weight of three pound box, shipping would be $8. No matter how many I sell I can't make up that loss in volume
You can calculate dimensional shipping rates using Smart Boxing. We built the app for the exact reason you need it - dimensional shipping is a reality of ecommerce shipping, and accuracy is key to success.
You can easily handle this with the Multi Carrier Shipping Label app. The app helps you calculate shipping based on the volumetric weight of the product. Within the app, there is an option to enable/disable the volumetric weight of the product. Once it is enabled, the actual product weight and the volumetric weight is compared and the higher value is used as the weight. This weight is used to calculate the shipping cost. You can check out this guide to get a better idea regarding the process.
