Where does an alternate purchase point Bill To?

Happy Monday, all!
We recently created a new purchase point on a supplier. When it comes time to generate an invoice that we owe, is it going to have us pay the purchase point or the main supplier? Is there a way to control this? I’m pretty green on the SRM / AP side of things. I would’ve thought it would behave similar to a customer with alternate ship-to and a sales order.

Pays the Supplier. POs go to the Purchase Point. If there are different pay points, then we just set up different suppliers.

Nice! Thanks
