Custom Checkout Page

Some changes can be made using remove_action() and add_action() calls. For bigger changes you would make your own checkout templates.

Copy:
plugins/woocommerce/templates/checkout/the-ones-you-need-to-change.php
to
themes/my-child-theme/woocommerce/checkout/the-ones-you-need-to-change.php
and edit the copies.

You may need to update your copies if WooCommerce updates the master, which they do occasionally, so you would be making an on-going burden for yourself.

Either way, PHP skills or a developer will be needed.

We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
