Hello Dr. Burk,
This type of payment transfers are possible when you have integrated a payment gateway which offers “Split Payments” on your website. Some of the popular payments gateways which offer split payments are PayPal and Stripe.
Incase, you are looking for an experienced company which can help you create a charity website- which supports split payment, we will be happy to serve you.
You can share your requirements with us via https://www.yo-kart.com/contact-us.html or email us at sales@fatbit.com
Have a great day.
Warm Regards,
Yo!Kart Team
