Marketplace orders carry no approval stage of their own: recording, posting and reversing are governed by their own permissions (§1.12), and a draft posts only by a hand holding the post permission. The approval discipline enters at the payout — a Payment to a seller runs Procurement's course, approvals and auto-post included, exactly like a payment to any supplier (§4.8).
Where work hands from one person to the next — orders recorded by the marketplace team, payouts released by the accountant — the hand-off surfaces through the notification bell and the activity record, as everywhere in the application (§1.7). The working chase list is the sellers' payables themselves: AP aging (Chapter 4) shows what is owed to every seller, marketplace obligations standing in the open beside every other payable.
