Tips for taking a percentage out of each transaction you can generate?

Hello Indie Hackers,

I've been setting up quite a lot of websites recently, each one processing payments through Stripe.

I would like to know which way would be the easiest for me to recover a commission out of each sales. Ideally, I should be able to take a percentage on each transaction processed by Stripe.

Is there a way of doing so?

Cheers
