Here’s a simple PHP snippet to add a fee to the checkout for every payment or for a specific payment gateway.
Please do remember that for certain payment gateways such as PayPal, adding checkout fees is currently against their Terms of Service so make sure to check this first.
As usual, this needs to be copied and pasted in your child theme’s functions.php file. Enjoy!
