This plugin is best fitted for not so precise people. When products are sold mostly with one piece per order, it is easy to overlook multi-quantity orders. This plugin will highlight the background of the quantity cell if the quantity is over one.

Highlight Multiple Quantities In Order

Works great

Highlight Multiple Quantities In Order makes important highlight on order if customer have ordered over one quantity of a single product.

WooCommerce uses number inputs for the cart quantities by default, as most browsers now support <code><input type="number" /></code>.
However, you may want to have JavaScript powered inputs if you want greater control over appearance. Simply install and activate this plugin to do so.
It optionally includes a <a href="https://github.com/jonstipe/number-polyfill" rel="nofollow ugc">Number Polyfill</a>, which is a polyfill for implementing the HTML5 <code><input type="number"></code> element in browsers that do not currently support it.
To include this, add the following code to your theme’s <code>functions.php</code> file:
<pre><code>add_action( 'wp_enqueue_scripts', 'wcqi_enqueue_polyfill' );
function wcqi_enqueue_polyfill() {
 wp_enqueue_script( 'wcqi-number-polyfill' );
}
</code></pre>
