PIRATE SHIP WORKFLOW
Labels are prepared by export.
Pirate Ship doesn't provide an API for custom sites, so CMBTrades creates an order spreadsheet for you. Upload it to Pirate Ship, map the address/weight/dimension columns once, buy the labels there, then enter the tracking number back into Orders.
