<h2 style="color: #f5247d">Sell license keys for software</h2>
<p><strong>WooCommerce Software Add‑on</strong> gives you end‑to‑end licensing inside WooCommerce. Generate keys on purchase, manage activations and upgrades, and keep support simple by managing everything where you already fulfill orders.</p>
<h2 style="color: #f5247d">Sell licenses and upgrades</h2>
<p>Mark any product as software, set licensing rules, and let the add‑on handle the rest. Customers buy like any other product, and when the order is <strong>completed</strong> they automatically receive their license key, activation email, and activation limits in the order‑complete message.</p>

<p>If you introduce a paid upgrade, define eligible past keys and an upgrade price. During checkout, customers enter their existing license and receive upgrade pricing automatically.</p>
<h2 style="color: #f5247d">View purchased keys</h2>
<p>See exactly which key belongs to which order, including remaining activations, right on the WooCommerce Edit Order screen. Need to resend the license email? Use the built‑in “Send” action without leaving WooCommerce.</p>

<p>For a global view, go to <strong>WooCommerce → License Keys</strong> to search, filter, and bulk‑revoke keys when necessary.</p>
<h2 style="color: #f5247d">Track activations and view reports</h2>
<p>Understand usage at a glance. The <strong>WooCommerce → Reports → Software</strong> dashboard summarizes sales and activation activity so you can spot trends, enforce limits, and plan upgrades.</p>

<h2 style="color: #f5247d">Integrate with your app via API</h2>
<p>Validate licenses from your desktop app, plugin, or SaaS. The API supports generating keys, activating, de‑activating, resetting, and checking validity so you can enforce licensing where it matters: inside your software. See the documentation for endpoints and examples.</p>

<h3>Rule-Based Blocking</h3>
<p>Build your own defense with powerful, flexible rules. Target orders by email address, domain, phone number, IP address, country, city, postcode, billing or shipping address, customer name, payment method, or shipping method. Choose from exact match, contains, wildcard, or regex matching. Set rules to block, hold, or flag — and add expiration dates for temporary rules.</p>
</div>
<div class="">
<h3>Intelligent Risk Scoring</h3>
<p>Every order is automatically assessed against six configurable risk signals: disposable email detection, IP reputation tracking, billing/shipping country mismatch, suspicious address keywords, new account age, and high-value order thresholds. Each signal has an adjustable weight, and you set the thresholds that determine whether an order is blocked, held, or flagged.</p>
</div>
<div class="">
<h3>Real-Time Checkout Protection</h3>
<p>Shop Defender intercepts fraudulent orders at the earliest possible moment — before payment is processed. Full support for both the classic WooCommerce checkout and the newer WooCommerce Blocks checkout. When an order is blocked, draft orders are automatically cleaned up and the customer sees your customizable error message.</p>
</div>
<div class="">
<h3>Order Risk Assessment</h3>
<p>Every order gets a detailed risk assessment stored as metadata. A dedicated metabox on the order page shows a color-coded badge (blocked, on hold, flagged, or low risk), a visual risk score bar, and a breakdown of every risk factor that contributed to the score. Optionally display a fraud risk column directly on the orders list.</p>
</div>
</div>

<li><strong>Flag</strong> – The order completes normally but is marked with a warning. A note and risk score are attached for your review when fulfilling.</li>
</ul>
<p></p>
