Hello,

Thank you for your question.

You can try to do the following:

1. Enable the option Redirect to the cart page after successful addition in WooCommerce -> Settings -> Products -> Display.

2. Disable Enable AJAX add to cart buttons on archives at the same place.

3. Set your cart page to be your checkout page in Woocommerce -> Settings -> Checkout.

Hope this will help you.

Kind Regards
