Set Shipping Based on Quantity Per Product or Cart Total

Flexible Shipping Rules for WooCommerce is a plugin that allows per-product shipping rules with quantity-based pricing and free shipping thresholds.

Flexible Shipping Rules gives you complete control over shipping costs on a per-product basis. Set up quantity-based shipping rules, fixed shipping prices, and free shipping thresholds for individual products.

Frequently Asked Questions

= How does the priority system work? =

Free shipping quantity takes priority over all other settings. If the quantity threshold is met, only free shipping will be shown.

= Can I have different rules for different products? =

Yes, each product can have its own custom shipping settings that override global settings.

= What happens if I set both fixed price and per-unit pricing? =

Fixed shipping price takes priority over per-unit pricing.

= How do I set up global free shipping? =

Go to WooCommerce > Settings > Shipping and configure:

1. Check “Enable Global Free Shipping”
2. Choose “Free Shipping Type” (Cart Value or Cart Quantity)
3. Set the appropriate minimum value or quantity

= What’s the difference between cart value and cart quantity free shipping? =

Cart Value: Free shipping when the total cart value reaches a certain amount (e.g., free shipping on orders over £50).

Cart Quantity: Free shipping when the total number of items in the cart reaches a certain amount (e.g., free shipping on orders with 10+ items).

= Do global settings override product-specific settings? =

No, product-specific shipping rules take priority over global settings. If a product has custom shipping enabled, those rules will apply instead of the global settings.

= How does flat rate shipping work with free shipping? =

Flat rate shipping applies when the cart doesn’t qualify for free shipping. The priority order is:

1. Product-specific shipping rules
2. Global free shipping (if qualified)
3. Global flat rate shipping (if qualified)
4. Default WooCommerce shipping methods

= Can I set different flat rates for different cart ranges? =

Currently, the plugin supports one flat rate amount. For complex tiered pricing, you would need to use product-specific shipping rules or WooCommerce’s built-in shipping zones.

= Why do I only see one shipping method? =

The plugin is designed to show only the most appropriate shipping method to avoid customer confusion.
