YITH WooCommerce Checkout Manager (Premium Plugin):
WooCommerce checkout page is fixed and you do not have control over it. But we have seen few extensions earlier which let you change the way it gets displayed. For example, we have seen a checkout page for digital goods which only shows relevant fields to the customer. Another one was a multi-step check out which breaks the checkout process into multiple sections and shows them one by one. And here is yet another one which gives you complete control over checkout fields.
YITH WooCommerce Checkout Manager Premium allows you to modify checkout page completely by adding fields or removing fields. Many times you will feel that you need to have more information about your customer and for that, you can always add one or more fields to the checkout page and make it compulsory. Sometimes you may feel that few fields are unnecessary and this extension will let you remove them from the checkout page.
Designing the checkout page will be just a few clicks away as well. You can modify the looks and behavior of the checkout page. You can add some colors to input fields that can change colors if the data provided is not valid or missing. Even if you do not want to do anything the checkout page, leave all field as it is and nothing will change. So keeping it in the backend will never hurt your site.
