Canceling orders in 3Dsellers helps you handle situations where an order cannot be fulfilled, such as customer cancellations, out-of-stock items, address issues, or payment problems. When canceling an order, you’ll also have the option to reallocate the canceled quantity back into your inventory, which helps keep stock levels accurate.
Accessing Order Cancellation
To cancel an order in 3Dsellers:
Log in to your 3Dsellers account
Go to Orders or Orders & Disputes
Locate the order you want to cancel. In Simple View, open Actions, then More Actions, instead of the lightning bolt. The Cancel order item is available for eBay (hidden once the order is Cancelled), Walmart, Shopify (greyed out when the order is Completed), TikTok, BigCommerce and manual orders. For WooCommerce use Set Order Status; Etsy and Amazon orders have no cancel item.
In Old View, open the action menu (lightning-bolt icon in the Actions column)
Select Cancel order
Understanding the Cancellation Modal
When you cancel an order, a Cancellation modal will appear. On eBay it first checks eligibility. If the order is not eligible it shows This Order is ineligible for cancellation: with the reasons in red, for example the time window for order cancellations has expired, a case or inquiry exists for a line item, the order has already been fully refunded, or the order or one of its line items has already been shipped. If the buyer already asked to cancel, the text reads Are you sure you want to accept this cancellation?, Cancel Order accepts it and a red Reject button appears; there is no second confirmation. The reasons are listed under Please choose your cancellation reason: and depend on the channel: eBay offers Buyer provided wrong or bad address, Buyer asked to cancel this order (the default), Buyer has not paid for the transaction and The item is defective or out of stock; Shopify offers Other, Customer, Declined, Fraud and Inventory; Walmart offers Customer requested, Price mismatch, Out of stock, Fraud stop shipment and Address not serviceable. The dialog includes:
The Order ID you are about to cancel
A Cancellation Reason dropdown
(Optional) Cancel Specific Transaction switch (Walmart orders only; it replaces the single reason with one reason per line item)
The Inventory Reallocation checkbox
A warning that the action is irreversible
Buttons for Cancel or Cancel Order
⚠️ Please note: Canceling an order cannot be undone.
Step-by-Step: Canceling an Order
Open the order and click Cancel order
Confirm the order details are correct
Select the appropriate cancellation reason
(Optional) Enable Cancel Specific Transaction (Walmart orders only) to give each line item its own reason
Choose whether to keep Inventory Reallocation enabled
Click Cancel Order to confirm
Once confirmed, the order status will update to Cancelled in your Order Manager.
Inventory Reallocation (Catalog Requirement)
When canceling an order, you may see this checkbox:
✅ Reallocate order quantity back to 3Dsellers product catalog warehouse
What it does
When enabled, 3Dsellers will attempt to return the canceled quantity back into your inventory so the item becomes available again for future orders.
Important: When reallocation works
Inventory reallocation will only work if you are managing inventory through the 3Dsellers Product Catalog, meaning:
The product exists in your Product Catalog
The order item is linked to that product (SKU match)
Your inventory is being tracked through the Product Catalog warehouse
When it won’t update inventory
Reallocation will not return stock if:
You don’t manage inventory through the 3Dsellers Product Catalog
The SKU is not connected to a catalog item
The product does not exist (or was deleted) from your catalog
✅ Best tip: If reallocation isn’t changing your inventory, the first thing to check is whether the item is properly set up in your Product Catalog and using the same SKU.
Automatic Refund Processing
When an order is canceled, 3Dsellers automatically sends a refund to the buyer if payment was received, using your preferred payment method.
If payment was received → refund is processed automatically
If payment was not received → no refund is needed
Refund timing depends on your payment provider and may take a few business days.
Best Practices for Order Cancellation
Before Canceling
Verify the order ID and items to make sure you’re canceling the correct order
Check the order status (some orders may require return handling instead of cancellation). To refund without cancelling, see Order Actions: Refund, Assign, Pick Status, Tax Details.
Confirm inventory availability before deciding whether to reallocate stock
Consider alternatives such as partial cancellation for multi-item orders
During Cancellation
Always select the correct cancellation reason
Leave Inventory Reallocation enabled if you manage inventory through the Product Catalog
Use Cancel Specific Transaction (Walmart orders only) to give each line item its own reason
Review the warning message carefully before confirming
After Canceling
Confirm the order status changed to Cancelled
If reallocation was enabled, verify inventory updated in your Product Catalog warehouse
Monitor refund activity if payment was received
Document common cancellation reasons to spot trends (ex: frequent out-of-stock issues)
