Tips & Donations at WooCommerce Checkout

The plugin simply adds “Tips” field to your website’s WooCommerce Checkout Form.
It can add it as a native fee and via the Notice box as well.

Once the plugin is installed and activated, you will have a new field in the Checkout Form where your customers can add optional tip&donation.
