Shopify has three order statuses to note whether an order has shipped yet:
Unfulfilled
Fulfilled
Partially fulfilled
Pirate Ship imports only Unfulfilled orders by default
Unfulfilled Orders Only: Pirate Ship will only import Unfulfilled orders. If you want to import an order that is currently marked as Fulfilled or Partially fulfilled in Shopify, you'll need to manually change the order back to Unfulfilled in Shopify's dashboard and then refresh Pirate Ship's import page.
Here's how that looks:
Orders You Buy Labels For Get Marked as Fulfilled: When you buy a label for a Shopify order with Pirate Ship, the order is automatically marked as Fulfilled in Shopify.
To avoid accidental duplicate shipping, you must request a refund for the label in Pirate Ship before it will reappear in your Import grid, even if you manually mark the order as Unfulfilled in Shopify.
