YiThemes - YITH WooCommerce Checkout Manager v1.2.1
You miss only one step to sell your products online. You configured everything, but when you test the first purchase you notice some essential and unnecessary data are missing on your checkout page. Unfortunately, WooCommerce doesn't allow you to change or add checkout fields, therefore if you need, for example, to insert VAT or tax code, you have no possibility to do it.
