The lot as one system —
and the only one that knows what a unit costs you per day it sits.

4barrel OS is built for the 20–60 unit independent lot where the owner is the buyer, the recon manager, the salesperson, the title clerk and collections — often all before lunch. Inventory with running all-in cost, the recon gate, the desk, leads, online sales, and the paperwork that keeps you out of trouble. Not a franchise DMS priced for a store fifty times your size — the whole lot, in one place, at your size.

Days-on-lot is a bill, not a stat. Every unit carries its real basis — auction hammer, fees, transport, recon, and the floor-plan interest that grows every single day it sits. The Command Center's top number is the money tied up on your lot and what the carry is costing you today.

Two gates keep you honest. A unit can't hit the line until recon reads Ready. A deal can't be delivered until the title is in hand, the FTC Buyers Guide is posted, and the odometer is disclosed. The paperwork is the thing most likely to actually cost you money this year — so the OS treats it like a gate.

This is the real OS, not a slideshow. It runs entirely in your browser. Everything you type stays in this tab, nothing is uploaded, and the lot resets when you leave. Nothing here lists, delivers, spends or signs — anything that would is staged on the Approval Desk instead.
