If you receive multiple orders that ship to the same destination, you may want to combine them into a single order so you can ship them in a single shipment. In this case, ShipStation allows you to combine multiple orders into a single order.
ShipStation also provides Combine Order Alerts to let you know when orders import and can potentially be combined. These alerts appear in a red bubble on your profile icon in the top right of your ShipStation screen.
For a combine order alert to appear, two or more orders must have both a matching customer ID and Ship To address.
Conversely, you may receive a single order with multiple items that need to be shipped separately. Or one item on the order may be fulfilled by a third-party fulfillment service (like FBA) while the other item is shipped from your own warehouse. In this case, ShipStation allows you to split the order into multiple orders so you can create separate shipments for them.
Review the instructions below for combining and splitting orders in ShipStation.
Not all selling channels support the shipment update we send after an order has been combined or split.
At this time, orders combined or split in ShipStation for Amazon, OpenSky, SellerActive, or TradeGecko will not update correctly on the selling channel, and so we do not recommend combining or splitting orders from these selling channels in ShipStation. If you have done so, you will need to manually update the selling channel with your shipment information. See our Integrations Guide for more information.
If you need to ship multiple orders to the same location as a single shipment, ShipStation lets you combine the orders into a single order and create a single label for it.
Try ShipStation V3
ShipStation V3 lets you combine items from multiple orders into a single shipment without combining multiple order records into a single order in ShipStation. This lets the order records in ShipStation always match what you have in your selling channel and produces more accurate order and shipment reports.
Check out our Combine Shipments article for details on how this works in ShipStation V3.
Combine multiple orders into a single order by doing the following:
Select the orders to combine from the Order grid.
Click the Other Actions button and select Combine Orders.
Drag the order you want to be the surviving order to the top of the list.
Click Combine to complete the process.
ShipStation will combine all selected orders and their items into the single surviving order, and the other orders will disappear from your Orders grid. These orders cannot be restored, though you can split the order into multiple orders again if necessary (this will result in new orders).
If you need to ship only part of an order or ship the items in the order as separate shipments, ShipStation allows you to split an order into multiple orders so you can create separate labels for each shipment.
Try ShipStation V3
ShipStation V3 allows you to split an order's items into separate shipments within the order instead of splitting the order into multiple orders. This ensures the order records in ShipStation always match what you have in your selling channel and produces more accurate order and shipment reports.
Check out our Split Items Into Shipments article for details on how this works in ShipStation V3.
To split an order, do the following:
Select the order to split from the order grid.
Click the Other Actions menu and select Split Order.
In the pop-up window, there will be a new order number with a suffix (such as -1 or -2) and a list of products in the order.
Enter the quantity of each item you’d like in the new order into the New Order field.
Enter the Amount Paid, Shipping Paid, and Tax Paid you want reflected on the new order, if you would like to split the totals.
Whenever possible, split (or combine) orders directly in the selling channel before they import into ShipStation, rather in ShipStation directly.
You can also apply tags to the split order in the Split Order pop-up (for example, add a Backorder tag to the split order so the warehouse staff knows not to process the order yet).
Not all selling channels will accept a shipment notification for the split order. Those that do often require the order number to be exactly the same. In these cases, be sure to remove the -# suffix before confirming the split process.
The split action will be logged in the order's Order Activity section, but the activity prior to the split will not be copied to the new order.
We do not recommend attempting to recombine orders after a split. This can cause unexpected results when notifying the selling channel once the order has shipped.
Once you split an order, ShipStation will no longer import the marketplace status for that order. You will need to manually update the status of the ShipStation orders if the original order is shipped or cancelled on the marketplace side.
If you split or combine orders often, ShipStation V3 may be a better option for your workflow. See V3: Create Single Labels (V3) for more information.
