It looks like the cart is built to be extended on the payment processing side of things … is there a way to build shipping calculation modules (e.g., for UPS, USPS, FedEx, etc.) in the same manner?

Not really. There’s no clean way to provide a dynamic shipping price in SimpleCart currently. It’s possible to have a workaround where you use xPDO to create new shipping methods with the right price and apply that to the order, but that’s not great.

Commerce makes it a bit easier, with [custom shipping methods](https://docs.modmore.com/en/Commerce/v1/Developer/Custom_Shipping_Methods.html) baked in.

Ok, thanks for your response. My challenge is that I’m in search of a native modx cart for a job in the very near future. Commerce looks promising but it appears that a production version won’t be available for quite a while.

For future people looking at a SimpleCart way to do this. It is possible, but only if you have a custom payment processor to add “preHooks” to that adjust the custom delivery price before charging the order. You could also dynamically add/select shipping options to the methods database using hooks in your checkout form.
