A pre-order is a real Shopify order the moment the customer pays. Bloom holds its fulfilment until stock arrives, so your shipping app won’t ship it early - for most apps there’s nothing to configure.

​
What Bloom does to every pre-order

  • Holds fulfilment. Held orders drop out of Shopify’s Unfulfilled list until you release them, so shipping apps don’t see them as ready to ship.
  • Tags the order. Pre-order, plus Pre-order: All items or Pre-order: Some items. While held it carries Pre-order: Hold; when it’s safe to fulfil the tag flips to Pre-order: Ship.
Holds require Bloom’s fulfilment permissions - grant them when prompted in the app.

Any other appVaries-Ask: does it respect Shopify’s On Hold status? Yes = nothing. No = hold orders tagged Pre-order, release on Pre-order: Ship
A mixed order (in-stock + pre-order items) shows up as one order in your shipping app. To dispatch the in-stock items separately, enable Split shipping in Bloom - see Split orders.
In ShipStation you can add a safety net: map Order Tags to a custom field under Edit Shopify Settings → Custom Field Mappings, then create an automation rule matching Pre-order with the action Hold Until.
