Sell at the counter with POS Express
POS Express is the fast path: it exists because a counter queue cannot wait for a full order form. It is a way into the same order, not a separate ledger.
Point of Sale is the counter: a till application for selling face to face, with registers and cash drawers a named cashier is accountable for. What it sells lands in Orders and comes off Inventory exactly as any other sale does.
A counter application with its own tills, registers and cash drawers.

Terminals are managed and viewed separately from selling on them, so the person on the till does not also hold the keys to reconfigure it.
A register and its drawer belong to a person for a shift. That is the mechanism by which a shortfall has a name against it, so do not share a register between people to save setting up a second one.
