Depending on which theme you use, and we recommend always using a child-theme, you will need to add a couple files to the theme folder. All these are stored in woocommerce folder we include with the plugin.

These files are:

  1. woocommerce/cart/cart/php which will show taxes in the cart by line item.
  2. woocommerce/order/order-details-item.php and order-details.php
  3. woocommerce/pdf/ which holds files for use with the pdf invoices plugin.
