Description
Modulux Shipping Helper for WooCommerce is a lightweight and modular WooCommerce plugin that allows merchants to define custom weight units and flexible shipping rules for each of your products.
Use it to handle shipping calculations when your products vary in volume, type, or measurement (e.g. Kg, Litre, Desi, Lbs). Choose between total or heaviest weight-based logic per unit and automatically apply fallback pricing, VAT, and free shipping thresholds.
A built-in “Suggest Weight” tool can recommend weight values using SKU/category/tag similarity, making it even easier to manage large product catalogs.
Key Features
- Define custom weight units (Kg, Deci, Liter, Pound, etc.)
- Configure flexible shipping rules for each unit
- Choose between Total or Heaviest Item calculation modes
- Add fallback pricing when no rules match
- Built-in VAT and free shipping threshold management
- Works only with WooCommerce’s Flat Rate shipping system
- AJAX-powered “Suggest Weight” button to automatically fill in missing weights
Shipping Logic
- Products are grouped by unit (kg, liter, etc.)
- Weight is calculated per unit:
- Total mode: sum of all product weights
- Heaviest mode: highest weight in the group
- Rules are matched per unit (
maximum price) - If no rule matches, a fallback is used
- The final cost is the sum of all matching units
- VAT is applied (if set)
- Free shipping is applied if the cart total exceeds the threshold
- Fallback is specified in the order management panel
