Many times, the quantity of an item needs to be changed after you have already begun the listing process. You may have found an extra one in your pile, or discovered one was damaged and need to remove it. If you are using InventoryLab to provide Box Content information to send to Amazon, making this quantity edit is easy!
For both Live (after you click Review Batch) and Private (after you create all of your shipments) modes, once you are on the Box Content screen, simply click directly on the Quantity for the item and it becomes and editable field.
To Remove all quantities of an item, edit the Quantity to 0 and you will be asked if you want to delete the item from your shipment.
Simply type in the correct quantity and hit Enter. You will notice that the quantity has now changed in the quantity box, near the Assign dropdown, and in your Working Shipment on Seller Central.
If you already have the items assigned to Multiple Boxes, you will need to adjust the quantities in your box assignments first to create the edit. This is because the system is unsure which box to remove the quantities from automatically.
For example, if I tried to adjust my quantity to 23, while all 24 items were assigned to 2 boxes, an error will appear.
However, if I unassign 1 of the items from the box I removed it from and then made the edit, there would not be an issue.
If you have already sent your Box Content information once and you need to still edit quantities, you can do this same capability through your Working Shipment!
First, on the List page of InventoryLab, click the 3 horizontal lines to the right of the Working Shipment that your item is in and select Box Content Information
You will see your shipment information open up on the right hand side where you can complete the original steps to edit your item(s)
Finally, click the Transmit Updated Boxes button in the lower right hand corner of the screen so Amazon can update the data for your box content details
That's it! You're all set to finish your shipment in Seller Central!
