I am using CubeCart for my client. The software does not have a module for FedEx. The developers of CubeCart say that they can't develop a module because it is impossible for them to get a test account set-up through FedEx. I know other shopping cart program developers have incorporated FedEx shipping into their carts so I know this can be done.
CubeCart Version 4
It is required that this module is installed and working on the website.
Must be experienced with programming CubeCart modules.
