<h3 class="whitespace-normal break-words"><strong>Automatic Country Code Addition</strong></h3>
<p class="whitespace-normal break-words"><strong>Let customers enter phone numbers their way.</strong> 99% of shoppers skip the country code when typing their number—and that’s perfectly fine. The plugin intelligently matches their phone to their selected country and adds the correct dial code behind the scenes. If customers want, they can simply type in the dial code themselves.</p>
<p class="whitespace-normal break-words"><strong>You get properly formatted international numbers. They get a frictionless checkout.</strong> Compatible with all WooCommerce checkout types.</p>

<h3 class="whitespace-normal break-words"><strong>Instant Error Detection & Prevention</strong></h3>
<p class="whitespace-normal break-words"><strong>Stop bad phone data at the source.</strong> Real-time validation blocks invalid numbers during checkout while clear, contextual error messages help customers self-correct instantly. See problem orders flagged in your admin dashboard before they ship.</p>
<p class="whitespace-normal break-words"><strong>Reduce delivery failures.</strong> When every phone number is validated before order completion, your carriers reach customers on the first attempt. Fewer returns, lower support costs, and happier customers who actually receive their delivery notifications.</p>

<h2>Give your customers the options they want</h2>
<p>Product Add-Ons is one of the most popular extensions available for WooCommerce. It gives you and your customers even more options, including (but definitely not limited to):</p>
<h3>Image-based selections</h3>
<p><img class="alignnone size-large wp-image-18734005148756" src="https://woocommerce.com/wp-content/uploads/2013/05/woocommerce_product-addons_single-product-images.png?w=980" alt="WooCommerce Product Add-ons, image-based product add-on selection." width="980" height="741" /></p>
<p>A picture is worth a thousand words, so why describe a customer’s personalization options when you can show them? With image-based selections, customers can see what they’re getting before they buy.</p>
<h3>Flat fees</h3>
<p><img class="aligncenter size-large wp-image-18734005148960" src="https://woocommerce.com/wp-content/uploads/2013/05/woocommerce-product-addons_example-gift-options-configured-1.png?w=980" alt="" width="980" height="536" /></p>
<p>Charge customers a flat fee regardless of how many products they ordered. Perfect for a one-time set-up charge or a rush fee.</p>
<h3>Percentage fees</h3>
<p>Charge a fee for the add-on based on a percent of the total price—this is especially useful for service-based add-ons that can be tougher to boil down to a flat fee.</p>
<h3>Text input</h3>
<p>Let your customers enter custom text to create a custom t-shirt, add a monogram or personalize a card.</p>
<h3>Dropdown</h3>
<p>Customer can choose between a few pre-defined options with a drop-down field for your add-on.</p>
<p><b>Checkboxes</b></p>
<p><img class="aligncenter size-large wp-image-18734005148765" src="https://woocommerce.com/wp-content/uploads/2013/05/woocommerce_product-addons_single-product-gift-options.png?w=980" alt="An example of checkbox-based options for Product Add-ons." width="980" height="749" /></p>
<p>Make customization as simple and satisfying as checking a checkbox. Great for add-on services, like gift wrapping or express shipping.</p>
<h3>Custom price</h3>
<p>Let your customers name their price, perfect for tips, donations, and gratuities!</p>
<p>Add-ons can be named, described, reordered, and (optionally) given prices.</p>
<p>The extension also works with:</p>
<ul class="wccom-tick-list">
<li><a href="https://woocommerce.com/products/woocommerce-subscriptions/">WooCommerce Subscriptions</a> – add additional options to subscription products.</li>
<li><a href="https://woocommerce.com/products/woocommerce-bookings/">WooCommerce Bookings</a> – offer upgrades like an oil treatment for a massage, priority seats for their tour or a rush fee for their rental.</li>
