<h2>Custom Order Numbers for WooCommerce</h2>
<p>The <strong>WooCommerce Sequential Order Numbers Pro</strong> plugin allows your store to have sequential, rather than random, order numbers. Additionally you can customize your order numbers by setting a starting number, order number length, and custom prefixes and suffixes. Instead of your order numbers looking like 15, 16, 37, and so on, they could now be WT-01000-UK, WT-01001-UK, or whatever format you prefer!</p>

<h3>Tame your WooCommerce order numbers!</h3>
<p>This plugin works equally well for new and established stores: if your WooCommerce site already has orders placed, the sequential order numbers will pick up from the last order number, or begin with the starting number you configure. It’s your choice!</p>
