# BuyThis upgrade delta: wait BB then forward to owning sales

**Batch:** 81
**Order:** 200262129 / Tessa

Client paid difference for premium tubes; BuyThis held until amount reflected then forwarded to Tessa. Ephraim invented unrelated heat-exchanger ticket.

**Rule:** Upgrade POPs on BuyThis stay with store until BB clear, then owning AM sales; ignore Ephraim subject invent.
