What it does
Calculating shipping from raw weight and volume can get messy, and customers often dislike surprise fees at checkout. This extension takes a simpler route. You set up the boxes you actually ship in, assign each one a cost for a given shipping zone, and the plugin works out how many boxes an order needs. The result is a flat, box-based charge that stays consistent from order to order.
A packing algorithm fits products into your configured boxes using item dimensions and volume, then applies your rates. You can define multiple box sizes and multiple sets of boxes per zone, so local, regional and international orders can each use their own setup. Costs can be based on the box price, weight units, or a percentage of the value of the items inside. It requires WooCommerce and works within the standard checkout.
Best for
- WooCommerce stores wanting predictable flat shipping charges
- Shops shipping products in a few standard box sizes
- Stores selling regionally or internationally with zone-based rates
Features
Define multiple box dimensions for each shipping zone, so every destination can use the boxes and costs that make sense for it.
Set a flat shipping cost for each box, which keeps fees predictable for you and straightforward for customers at checkout.
A packing algorithm fits products into your configured boxes based on their size and volume, then calculates the rate from the boxes used.
Charge by box price, by weight unit, or as a percentage of the value of the items inside each box to match your pricing approach.
Set shipping costs for items too large to fit into any of your boxes, so those products still get a clear charge.
Use several box configurations within a zone to handle a catalog with varied product sizes and different order volumes.
Assign costs by destination so you can offer shipping to customers in other regions or countries with rates that fit each location.

Questions about Flat Rate Box Shipping
How does the plugin decide how many boxes an order needs?
It uses a packing algorithm that looks at each item's dimensions and volume and fits the products into the box sizes you have configured. Once the order is packed, it applies the rates you set for those boxes in the customer's shipping zone.
What happens if a product is too big for any of my boxes?
You can configure a separate shipping cost for items that cannot be packed into any box. That way oversized products still receive a defined charge at checkout instead of causing errors or confusion.
Can I charge something other than a flat amount per box?
Yes. Besides a fixed price per box, you can base costs on weight units or on a percentage of the value of the items inside the box, which lets you shape pricing around how your store operates.
Does it work with different shipping zones?
It does. Box sizes and rates are set per shipping zone, and you can use multiple sets of boxes within a zone. This lets you give local, regional and international orders their own rates.
