Box Sizes - Shopify DIY Real Time Shipping Quotes App

What Does the Box Sizes Feature Do?

The Box Sizes feature allows merchants to define the dimensions of the boxes they stock for shipping. Before requesting a parcel or postal quote, the packaging algorithm selects the correct box or combination of boxes for the items in the cart. The total weight and dimensions of the selected box(es) are then sent to the shipping carrier so that accurate shipping quotes are returned. Note: There is an incremental cost of $0.03 each time the packaging algorithm runs.

Alternatives to the Box Sizes Feature.

If you don't want to use the Box Sizes feature, other packaging options are included as part of your Real-time Shipping Quotes subscription at no additional cost. These options appear at the bottom of the Box Sizes page (click on "Box Sizes" in the app's navigation menu) in the Packaging method when standard box sizes is disabled section. Each option is listed below, along with its tendency to quote higher or lower than actual shipping costs.

• Quote each item as shipping as its own package.
  Each item in the Cart will be quoted as shipping as its own package. Unless orders are shipped this way, the shipping rate estimates using this method will tend to be high.
• Quote shipping as all items are in one box.
  All items in the Cart will be quoted as shipping in one box, and the shipping rate estimates will be based solely on weight. If the total weight of the Cart exceeds 150 pounds, it will be divided into multiple packages of equal weight. Shipping rate estimates using this method will tend to be low.
• Combine the weight of all items without dimensions and quote them as one package, while quoting each item with dimensions as shipping as its own package.
  A hybrid of the other two options. Shipping rate estimates may be higher or lower than the actual shipping charges, depending on the contents of the Cart.

4. Choose the Optimization mode. Two options are typically available: minimizing the number of packages, or minimizing the total package volume. Most merchants prefer the option to minimize the number of packages, as this generally results in the lowest shipping rate estimates.
5. Choose an option for the setting, Packaging method when standard box sizes is disabled. The Box Sizes feature will become disabled if the Enable checkbox is unchecked or the Capped amount is reached. When disabled, the fallback packaging method selected here will be used to generate shipping quotes.
6. Follow the instructions in the User's Guide to add boxes and complete the set up of the Box Sizes feature.
