Shipping workflow - managing shipping labels outside of orders
In eBay marketplace the shipping part is handled after the sale in my workflow. Moving to Magento I'd like to do something similar. If I want all my shipping to be "free" but I still want to be able to print labels for USPS or FedEx can this be done in Admin?
I have the shipping configured with USPS and FedEx correctly but I don't want to the customer to be able to select them and I would like to be able to price compare USPS and FedEx based on weight and shipping dimensions and then print the label. Is this possible in vanilla Magento 2.3.x or is there an extension or simlar that would work?
What is everyone else doing out there without having to have a FedEx and USPS window open to ship and compare prices?
