Hi @backwardsla
I understand that you want to offer users the provision to donate when they checkout.
The Donation For WooCommerce plugin is designed to serve this purpose.
You can watch a live demo of it here: https://demo.donationwoo.com/
Please go through the plugin’s documentation to get familiar with the features and options available: https://woocommerce.com/document/donation-product-for-woocommerce/
For any questions related to this plugin, you can create a ticket here. From there, click on the tab “I have a question about a specific extension or theme I’d like to purchase.”
Just so you know, in the WooCommerce.com marketplace we offer a 30-day refund policy so you can test the extension and make sure it works for you.
You can also explore other plugins that may meet your requirement, by searching here: https://www.google.com/search?q=donation+plugin+WooCommerce
