Enhances WooCommerce Flat Rate shipping by allowing per-product custom weight units, rule-based pricing, VAT, and smart calculation logic.

modulux

<p><strong>Modulux Shipping Helper for WooCommerce</strong> is a lightweight and modular WooCommerce plugin that allows merchants to define custom weight units and flexible shipping rules for each of your products.</p>
<p>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.</p>
<p>A built-in “Suggest Weight” tool can recommend weight values using SKU/category/tag similarity, making it even easier to manage large product catalogs.</p>
<h3>Key Features</h3>
<ul>
<li>Define custom weight units (Kg, Deci, Liter, Pound, etc.)</li>
<li>Configure flexible shipping rules for each unit</li>
<li>Choose between <strong>Total</strong> or <strong>Heaviest Item</strong> calculation modes</li>
<li>Add fallback pricing when no rules match</li>
<li>Built-in VAT and free shipping threshold management</li>
<li>Works only with WooCommerce’s Flat Rate shipping system</li>
<li>AJAX-powered “Suggest Weight” button to automatically fill in missing weights</li>
</ul>
<h3>Shipping Logic</h3>
<ul>
<li>Products are grouped by unit (kg, liter, etc.)</li>
<li>Weight is calculated per unit:
<ul>
<li><strong>Total</strong> mode: sum of all product weights</li>
<li><strong>Heaviest</strong> mode: highest weight in the group</li>
</ul>
</li>
<li>Rules are matched per unit (<code>maximum <span aria-hidden="true" class="wp-exclude-emoji">→</span> price</code>)</li>
<li>If no rule matches, a fallback is used</li>
<li>The final cost is the sum of all matching units</li>
<li>VAT is applied (if set)</li>
<li>Free shipping is applied if the cart total exceeds the threshold</li>
<li>Fallback is specified in the order management panel</li>
</ul>
