At what point does Snipcart take the 2% cut?

Just for the moment being, if there is an order being placed for 100$ when in the process of the order does snipcart decide that they will get the 2$. I want to use Pay Later for now and i’m wondering if a troll orders for 10000$, even if it’s not paid, and will never be produced. Will snipcart take 200$?

Maybe someone has some insights on this.
