Hey @dexterandreasson,
Happy to clarify that!
You certainly can use more than one payment method on your site at the same time.
If you navigate to Donations > Settings > Payment Gateways, you’ll see all the payment gateways available for you, and then select the ones you need.
These payment gateways will be available for each donation form on your website.
You can find further information about payment gateways in our documentation, which you can find here: https://givewp.com/documentation/core/settings/payment-gateways/
Please let us know if you have further questions on this or need any additional assistance!
