By default Bloom puts all items on hold
When an order contains a pre-order item, Bloom holds the entire order so in-stock items don’t ship before the pre-order stock arrives. Release a hold from the order page in Shopify admin.
To enable split shipping
- In Shopify admin, open Apps → Bloom.
- Go to Pre-order → Settings.
- Under Orders, open Order splitting.
- Tick Split orders with pre-order and non-pre-order items.
- Click Save.
Splitting relies on Shopify’s pre-order purchase option. If you turn off Enable purchase option at checkout in Pre-order settings, Shopify can’t split - Bloom holds just the shipments containing pre-order items.

Turn split shipping on or off in Shopify
- In Shopify admin, go to Settings → Shipping and delivery.
- In the Shipping section, click split shipping (or Manage if you don’t have fulfillable inventory settings enabled).
- In the modal, tick or untick Show split shipping in checkout.
- Click Save.


- On - a mixed cart shows separate shipments at checkout. In-stock items ship now, pre-order items ship later. The customer picks a shipping method for each shipment.
- Off - the whole order ships together once every item is ready.
How Bloom explains it
Bloom communicates your delivery approach across every surface, so the customer knows what to expect:- Cart - the pre-order message on each cart line.
- Checkout - the pre-order banner (Shopify Plus only).
- Thank you page - a pre-order notice straight after the order.
- Order status page - a per-line ship date and a pre-order notice. See the quick start to add the block.
