A transaction fee is a percentage deducted from each payment processed through your community.
On all paid plans, GroupApp charges 0% transaction fees. Unlike other platforms, GroupApp does not take any share of your revenue, and there are no hidden charges: You keep everything you earn.
Stripe charges a standard credit card processing fee of 2.9% + 30 cents per transaction, which applies to all plans and is set by Stripe, not GroupApp.
