Then Patreon came up with the same $0.50 / transaction number. However, since their average transaction amount is so much lower, they have to charge a higher number in order to make their target.
To illustrate how bad it can get - in EU VAT, if your yearly sales are over 30,000 Euros (it may even be 10k, I don't know the latest limit), you have to charge your customers/patrons the appropriate tax rate of the country that they are in. And if you don't, you may end up having to deal with the tax authority of that particular country.
People take this lightly, but as many are finding out, its serious business.
...
And - fraud is not handled by Paypal. Any chargeback, fraud, refund is your responsibility. You can even get your Paypal suspended for those reasons.
And no payment processor or retailer deals with fraud. They all suspend your accounts for chargebacks. The fee is the built in fee to cover _losses due to fraud_, not for "handling" it.
I think there's a reasonable case to view Patreon as a platform, not a pure payment processor.
Patreon is much more exposed to competition than the app stores, which are "protected" by the device duopoly.
I replaced it with a simple Ko-fi shop where you can just upload anything up to your 200GB quota (if you're a Gold member): https://ko-fi.com/s/7e9f22c63b
So either Patreon has an order of magnitude more fraud going on or is massively wasteful in its business operations. Probably both.
