Are Shipping Integrations working in United States

Greetings,

I’ve been reading about shipping integrations.

There are three platforms listed to integrate (PackLink, LetMeShip, and SendCloud).
If I go to any of the respective websites and try to use their web interface to ship
a package from USA to USA, all three systems say it’s not possible.

Are the shipping integrations only good for users with ERPNext outside of the USA?

I get an error like: No services available for the selected route and package combination

Link to Packlink quote.

Bump?

Does anyone know if any of the three integrations can be used from USA to USA shipments?

Thanks!

Does anyone have any input?

Please, we need community support in open-source projects like ERPNext.
