When do I get paid?

Not on delivery, and not on a weekly cycle. The carrier's first scan is what releases it. Hand the package over and the payout moves the same day the scan lands.

What releases is the lot price less the 5% fee. If the buyer paid shipping, that covers your label. You only pay the part a label costs above what they paid. If shipping was free or the lot had no box on it, the label is yours and shows on the sale as a shipping adjustment.

From there it is Stripe's deposit schedule, not ours.

Payouts are held, never lost, until Stripe onboarding is finished and a backup card is on file. Complete both and everything held releases at once.
