If you are looking for an easy way to ask for and collect pre-defined donations/tips in your WooCommerce checkout page, then you’re in luck! I just made a lightweight plugin that does exactly this.
The donations/tips box will be output in the checkout page, using the
woocommerce_review_order_before_payment hook. This is what it would look like:
There are 3 fields where you (the admin) can set some pre-define donation values, which will be displayed in the checkout page. You are also able to add your own title to the box.
Once a donation/tip amount is selected by the user (if any), it will automatically be calculated and added to the cart totals.
You can download the free plugin here.
