<p><strong>Auto SKU Generator</strong> takes the hassle out of creating SKUs for your WooCommerce products. Instead of manually typing a SKU for every product, this plugin automatically generates structured, unique SKUs based on your product’s category and ID.</p>
<h4>How It Works</h4>
<p>When you create or save a WooCommerce product without a SKU, Auto SKU Generator automatically assigns one using a consistent format:</p>
<p><strong>[Prefix][Product ID][Suffix]</strong></p>
<ul>
<li>The <strong>prefix</strong> is derived from the product’s category ID (zero-padded to 3 digits) or a custom prefix you define per category.</li>
<li>The <strong>product ID</strong> portion is zero-padded to fill the remaining SKU length.</li>
<li>A trailing digit is appended to ensure uniqueness in case of collisions.</li>
</ul>
<h4>Features</h4>
<ul>
<li><strong>Automatic SKU assignment</strong> — Products saved without a SKU get one automatically.</li>
<li><strong>Two prefix modes</strong> — Use the category ID as a prefix, or define your own custom prefix for each category.</li>
<li><strong>Configurable SKU length</strong> — Set your preferred total SKU length between 8 and 20 characters.</li>
<li><strong>Live SKU preview</strong> — A suggested SKU appears below the SKU field on the product edit screen, updating in real time as you change categories.</li>
<li><strong>Click-to-insert</strong> — Click the suggested SKU to instantly populate the SKU field.</li>
<li><strong>Collision handling</strong> — If a generated SKU already exists, the plugin automatically tries alternative suffixes.</li>
<li><strong>Settings page</strong> — Configure everything from Products > Auto SKU Generator in your WordPress admin.</li>
<li><strong>Clean uninstall</strong> — All plugin data is removed when you delete the plugin.</li>
</ul>
<h4>Use Cases</h4>
<ul>
<li>Online stores with large product catalogs that need consistent SKU formatting.</li>
<li>Shops where multiple team members add products and you want standardized SKUs.</li>
<li>Stores migrating from another platform that need to establish a new SKU system.</li>
<li>Any WooCommerce store that wants to save time on manual SKU entry.</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>WordPress 5.6 or higher</li>
<li>WooCommerce 5.0 or higher</li>
<li>PHP 7.4 or higher</li>
</ul>
