How to Make Some Required Fields Optional on WooCommerce Checkout Page

Do you use test/staging sites? Visit qSandbox for more info.

WooCommerce allows you to quickly start an e-commerce store.

At some point you may need to customize some of the checkout fields to fit your project requirements.

WooCommerce like other well written plugins uses hooks extensively. Those are actions and filters which allow you or your developer to customize the WooCommerce functionality without hacking the code. Another benefit of using hooks is that those customizations will survive any WooCommerce updates.
