What's the ballpark figure for the payments for this side project? $200 seems extreme unless your side project is charging $10,000~ per payment.
Fee $310.80
> Application fees: $180.00
> Stripe processing fees:$130.80
Some on this forum may even say it's great that the APIs provided enable someone to build this additional payment app on top of Stripe that makes it easier for you to take payment in exchange for a 180 / 4500 = 4% cut. However maybe you should look into lower cost payment methods if possible.
