You don't need to send the seller 'confirmation' you have received the item for them to be paid

The seller *does* need to be signed up to Managed Payments AND if they are a new seller or a seller who has not sold in a long time, their funds will be on hold for 14-30 days

So check with your seller as to if either of those things are the reason they have not received their funds
