Because authorize.net is a payment gateway, not a processor. You'd still need a processor and the one your bank works with will have similar requirements.
Honestly, those rates are better than I expected. I think OnlyFans has a 20% rate and the one real experience I have had with processors that handle adult industry was nearing 30%. They had legitimate fraud problems though.
- $25.00 - Monthly fee for the merchant account.
- $19.95 - Monthly fee for the Authorize.net payment gateway (API Connection to your website)
- 3.95% - Keyed rate
- $0.25 - per transaction fee
- $1,450 - HIGH-RISK fee
- 10% Rolling reserve
It just seems unfair, as these fees are for "adult content" sites (i.e. nudity, etc.), which is not what I built.
