WooCommerce Flat Rate Box Shipping is an advanced logistics plugin that allows you to calculate shipping costs based on boxes (packages) instead of just individual items or total weight. It is the ideal solution for stores that use fixed-size boxes (such as postal service or carrier packaging) and need to optimize packing.

How the Algorithm Works

Unlike WooCommerce’s standard “Flat Rate” method, this plugin uses a smarter packing logic:

• Box Definition: You configure the dimensions (length, width, height) and maximum weight.

• Automatic Calculation: When a customer adds products to the cart, the plugin attempts to fit them into the available boxes.

• Cost per Box: If the order fits into a small box, the customer pays a predefined rate (X).

Key Features

• Multiple Rates by Zone: Set different costs for the same boxes depending on the destination.

• Handling Fees: Add a fixed or percentage-based fee per box.

• Packing Priority: Define which boxes should be tested first to ensure the lowest possible shipping cost.

• Support for Individual Items: Configure products that cannot be grouped and must always be shipped in their own boxes.

Benefits for Retailers

• Accurate Shipping Costs: Prevents losses from bulky shipments that standard weight-based calculations may not detect.

• Transparency: Customers pay the exact cost of shipping for their order.

• Logistics Efficiency: You’ll know in advance which type of box is needed for each order
