Anybody else getting invoiced orders?

Maybe it’s been like this for a while and I have just never seen it, but I just got an order placed by a business account with invoice terms. So even though my item was fulfilled immediately (FBA), I don’t get paid for up to 37 days. From what research I did I found the accounts are supposed to pay anytime within 30 days, but Amazon will step in and find the seller 7 days past that. You can get paid immediately for a 1.5% fee.
