It would a nice benefit if you could discount the credit card processing fees during the repayment period.
E.g. You charge a 10% upfront fee for the loan, and repay at a 10% rate, from the perspective of the company they’re actually paying 12.9% to Stripe during repayment.
If you could pay just the 10% or even if you just got a .5% reduction to 12.4% overall going to Stripe during the repayment period, it becomes more of a win-win and a nice customer loyalty type bonus.
