Configuring the Flexible Shipping cost calculation rules for shipping boxes

Flexible Shipping Box Packing WooCommerce plugin adds two new shipping cost calculation conditions to the standard ones available in the Flexible Shipping free and Flexible Shipping PRO version:

  • Box type – allows to configure the shipping cost to be based on the type of the boxes used to pack the ordered products for shipping,
  • Number of boxes – allows to make the shipping cost dependent on the number of boxes used for shipping the products.

Both of them can be selected the standard way on the Flexible Shipping shipping method’s configuration screen from the When-conditions dropdown list:

Usage examples

Additional cost per each one shipping box

With the Flexible Shipping Box Packing plugin on you can use the Additional Cost feature to charge your customers with an extra fee per each one shipping box used respectively:

Configuring the shipping cost calculation rule the way above will result in charging your customers $5 per each 1 box used to pack and ship the products, e.g. $5 if 1 box was used, $10 if 2 boxes were used, $25 if 5 boxes were used, etc.

Fallback for no matching shipping boxes

If the products the customers order cannot be matched and packed into the shipping boxes you have defined, you can configure the Box type: No matching boxes rule to have such exception covered and use a specific cost value as a fallback:

In such case, according to the shipping cost calculation rules visible in the screenshot above, the $50 fallback shipping cost will be applied if all of the ordered products cannot be matched to the configured shipping boxes.

FS PRO Hiding the shipping method once there are no matching shipping boxes to pack the products

Flexible Shipping Box Packing’s Box type: No matching boxes option when combined with the Flexible Shipping PRO’s Special action: Hide can be used to hide the specific shipping method if the products which customer wants to order cannot be packed into the defined shipping boxes.

If you add the following rule at the very top of the FS shipping cost calculation rules table:

this particular Flexible Shipping shipping method will be hidden, when the products the customer wants to order cannot be matched and packed into the defined shipping boxes.Please mind that if the rule above has been configured for the only one available FS shipping method in your shop, it will result in hiding it when the condition is met and then, in turn, preventing the order from being placed.

FS PRO Hiding the shipping method once the specific number of boxes is reached

Combining the Flexible Shipping PRO’s Special action: Hide with the Flexible Shipping Box Packing’s Number of boxes condition gives you also the possibility to hide the specific FS shipping method when the certain number of boxes used to pack the products is reached.

If you add the following rule at the very top of the FS shipping cost calculation rules table:

this particular Flexible Shipping shipping method will be hidden, when the number of shipping boxes used to pack the ordered products is 10 or more.
