paypal account versus paypal giving fund account for a charity

[Sunrise-Bakoteh]

We set up an account with PayPal for our charity and receive donations through it -through the logo button on all our webpages.

The online donation site we were also using has now closed so we were looking at new sites

Givey says it works through PayPal giving fund.

What is the difference between the account we have and the PayPal giving fund account?
