Packaging Methods

  1. Individual Packing – Each item is packed separately. Total shipping cost is calculated by adding the shipping cost for each item.
  2. Pack into boxes with weight and dimensions – Allows you to set your custom box sizes. The best fit box is automatically chosen from the list by the plugin. In addition to this, you also need to select one of the parcel packaging algorithms:
    1. Volume-based packing: With this, the items are placed in the box based on the total volume of both items and the box they are packed into.
    2. Stack First Packing: With this, the items are stacked or pilled unto one another, based on either length, width or height of items as well as the box they are packed into. Read more…
  3. Weight-based shipping – In this method, you need to define the maximum total weight that the box can manage. Once the limit is reached, the remaining packages are added in a new box. Additionally, you can specify how the items have to be packed, that is, you can pack heavier items first, pack lighter items first, or pack based on weight.

Box measurement unit: Enable this setting if you are using the same weight and dimensions unit as you have defined in the WooCommerce settings.
