Hi,

Please navigate to the Dashboard > WooCommerce > Settings > Shipping > Shipping Options section. On that page you’ll find the ‘Shipping destination’ setting, which allows you to control which checkout fields should be used.

Use the ‘Force shipping to the customer billing address’ option to remove the shipping fields completely and use the billing fields for both billing and shipping. Plus points for WooCommerce on this, they automatically change the heading to show ‘Billing & Shipping’ on the checkout.
