Step 3: Prep & Boxem

In Step 3: Prep & Boxem, we'll assign the products in our shipment to boxes.

The name, destination, and number of units in the current shipment will be displayed at the top of the page. If Amazon split the products in the shipment between multiple destinations, you can click the arrow next to the current shipment name to select the other shipments.

An overview of the steps for creating boxes and assigning products to them can be found below to help get you started. For comprehensive guides to the different box content options available in Boxem, check out our other articles:

The left side of the page shows a list of the products. As you create boxes and assign products to them, they will be displayed on the right.


In the Products section, you'll see each product's image, title, ASIN, SKU, Condition, and quantity.

Next to each product are buttons to Assign, Bulk Assign, and Print FNSKU labels.

The number of units that need to be assigned will show and update as you add them to boxes.

Creating Boxes

To create your first box, you can click Create first box on the right side of the page to get started.

If you need additional boxes, enter the number of boxes and click the Create new box(es) button.

You can also create new boxes while assigning products, or create boxes in bulk by using the Bulk Assign or Dimensions & Weight buttons.

Assigning Products to Boxes

To assign a product to boxes individually, click Assign next to the product.

From here, you have the option to assign them manually or split them evenly between boxes.

The Bulk Assign function allows you to assign the product to boxes as you create them and enter their dimensions and weight, making it an excellent option for case-packed shipments.

Viewing/Editing Boxes

On the left side of the screen, you can view the contents of each box and make any needed changes.

The name, dimensions, and list of products assigned to each box will be displayed.

If dimensions and weight need to be entered for an individual box, click Set Dimensions and weight to enter them.

If you still need to enter dimensions and weight for multiple boxes, you can do this in bulk by clicking Dimensions & Weight at the top of the page.

To remove a product from a box, click the trashcan icon next to it.

Clicking the three vertical ellipses next to a box name will open a menu with the following options:

  • Edit Dimensions and weight
  • View Products
  • Duplicate
  • Delete Box

Note: Deleting boxes may cause your box names to be out of order. This can lead to issues when applying box labels, so we recommend changing your box assignments over deleting boxes when possible.

After you've assigned all of the products in your shipment to a box and entered the dimensions and weights for the boxes, click Continue to send Amazon the shipment details.

Once done, you'll move on to Step 4: Review & Ship.
