Hello,
Navigate to WooCommerce > Settings > Advanced and unset the Cart page.
Then, add the following custom css code in Theme Settings > Custom CSS:
.woocommerce-mini-cart__buttons .btn-cart {
display: none;
}
Make sure the Cart Sidebar is enabled from Theme Settings > Shop > Action after adding to cart.
This way, customers can add products normally, view their cart in the sidebar, and proceed directly to checkout without using the cart page.
Best Regards,
