<h3>Why this plugin</h3>
<ul>
<li>WooCommerce-focused SKU automation with both single-product and bulk generation workflows.</li>
<li>Slug mode and multiple SKU formats (numbers, letters, alphanumeric) in one settings screen.</li>
<li>Variation-safe generation with configurable separator logic.</li>
<li>Batch processing controls for large catalogs and lower-risk runs on weak hosting.</li>

</ul>
<h3>Settings Reference</h3>
<p>Use these options in WooCommerce → Settings → Products → SKU Settings.</p>
<ul>
<li><strong>Characters</strong> – sets the random SKU length.</li>
<li><strong>Prefix SKU</strong> – adds text before generated SKU (example: <code>BN_</code>).</li>
<li><strong>SKU format</strong> – choose numbers, letters, alphanumeric, or product slug.</li>
<li><strong>Add product ID</strong> – appends product ID to generated SKU.</li>
<li><strong>Take previous product</strong> – builds next SKU from the last published product (+1 sequence).</li>
<li><strong>Duplicate SKUs</strong> – allows repeated SKU values when your workflow needs it.</li>
<li><strong>SKU suffix</strong> – adds text at the end of generated SKU.</li>
<li><strong>Additional number</strong> – appends incrementing number in bulk mode (example: <code>001</code>, <code>002</code>, <code>003</code>).</li>
<li><strong>Format for Additional number</strong> – controls increment style with leading zeros.</li>
<li><strong>Enable variant settings</strong> – enables variation controls.</li>
<li><strong>Variable Product</strong> – enables/disables variation SKU generation.</li>
<li><strong>Variation Separator</strong> – separator between parent SKU and variation index (<code>-</code>, <code>--</code>, <code>/</code>, etc.).</li>
</ul>
<h3>Required Plugin</h3>
<ul>
<li><a href="https://wordpress.org/plugins/woocommerce/" rel="ugc">WooCommerce</a></li>
</ul>
<p>This plugin works only with WooCommerce.</p>
<h3>How it works</h3>
<p>The plugin uses WooCommerce product meta (<code>_sku</code>) and applies your rules from SKU Settings.</p>
<p>You can use it in two modes:</p>
<ol>
<li><strong>Product editor mode</strong>: SKU is generated while creating or updating a product.</li>
<li><strong>Bulk mode</strong>: SKU is generated for all products or selected categories.</li>
</ol>
<p>When “Re-create existing SKUs” is disabled, only empty SKU values are generated.</p>
<h3>Bulk SKU Generation</h3>
<p>Bulk generator supports:</p>
<ul>
<li>Generate SKU for all products.</li>
<li>Generate SKU by category.</li>
<li>Optional recreation of existing SKU values.</li>
<li>Progress indicator during processing.</li>
</ul>
<p>Increasing batch size speeds up processing but increases server load.</p>
