Simplest "Buy Now" popup

There are a few “cart” stack options for online payments, but I’m wondering if there’s something simple and cartless. I just want a “buy now” or “pay now” button that will popup a window for credit card payments (Stripe) followed by a notification that customer X has paid you.

I looked at the “Stripe Checkout” stack by Yuzool, but I see it was last updated in 2018 and isn’t even for sale anymore off their website. It seems to have been superseded by more complex “cart” featured stacks.

Does anyone know if “Stripe Checkout” still works? Or a better way to do this?

Take a look at Yabdab’s Paysnap.


Thanks. Does that have a cartless option by chance?
