It is the Netherlands’ post office
Hi there, is this a type of shipping software? If so, it might not be possible at the moment.
You can always contact our support team to confirm. 
Yes, it’s the Netherlands’ post office like USPS. I am based in Amsterdam and want to offer shipping locally and want to set it up through WIXStores.
@vlaude I understand now!
Currently we have a request to integrate more real time shipping carriers directly with us, you can vote for it here .
I did, however, do some research and found a possible solution. 
You can integrate Shippo with your Wix Store which is available in the Netherlands. Once integrated, you have the ability to add your own carrier account as mentioned in this Shippo article .
Hope this helps!
