Shippo — compare carrier rates and buy shipping labels without leaving SKU.io
If you ship orders from your own warehouse, buying the label has always meant leaving SKU.io: copy the address into another shipping tool, guess at the weight, pick a carrier, then paste the tracking number back. It's slow, it invites typos, and the shipping cost never makes it onto the order. Shippo fixes that. Connect your Shippo account and you compare live rates from every carrier on it, buy the label and print it, all from the fulfillment order. SKU.io records the shipment with its tracking and cost, and sends the tracking to your sales channel.
