The payment processing fees are levied by Stripe, the payment processing service.
Stripe charges 1.75% + $0.30 per transaction. This includes Visa, Mastercard, and American Express.

Stripe will deposit funds directly into your account.
NOTE: as part of your raffle set up, you can apply a Payment Processing Fee, which means you can pass on the Stripe fees to your customers. Most clients pass on the Stripe fees to their customers.
IMPORTANT: Stripe may reject your application if you are not registered with the Australian Charities and Not-for-Profits Commission or cannot demonstrate your not-for-profit status.
