Thanks Keith. From what Margot told you, I believe the process can still be improved.
From the time the buyer pays (when a "sold" banner is placed on the name in your account) to the time you are notified via mail takes 3 days. Then one more day to receive transfer instructions from the buyer. Going by what Margot told you, by the time you are being asked to transfer the name, the fund need only 1 more day to clear bank. However, BB starts counting a fresh 5 days from this day for its escrow to close, even when the buyer has received the name on the date you were asked to transfer it.
On the plus side, it appears the payment portal has been integrated with their payment processors. I was paid immediately after requesting. This is a great improvement over what used to be.
