If your Shopify orders are marked as shipped as soon as the order is placed, it is likely because your Shopify store is automatically marking all paid orders as "fulfilled".
This setting will prevent Duoplane from sending purchase orders to your vendors. The setting will also make order management more difficult, since it will be harder to determine which orders are actually fulfilled.
To turn off automatic order fulfillment in Shopify:
- In your Shopify admin, navigate to Settings > Checkout.
- In the Order processing section, look for the setting with the label "After an order has been paid".
- Select either "Automatically fulfill only the gift cards of the order." or "Do not automatically fulfill any of the order's line items."
