4barrel OS

4barrel OS

The operating system for a boutique, independent used-car lot

An independent lot does not run on a calendar. It runs on units — where the owner is the buyer, the recon manager, the salesperson and the title clerk before lunch, where every day a car sits is floor-plan interest nobody books, and where a deal delivered without the title in hand is the mistake most likely to cost you money this year. 4barrel OS is built for the twenty-to-sixty-unit lot, at your size, not a franchise DMS priced for a store fifty times bigger.

Days-on-lot is a bill, not a stat

Every unit carries its real basis — hammer, fees, transport, recon — and the floor-plan interest that grows every day it sits. The top number is the money tied up on the lot and what today's carry costs.

The recon gate

A unit cannot hit the line until recon reads Ready. Units in recon are counted on the home screen.

The titles and compliance gate

A deal cannot be delivered until the title is in hand, the FTC Buyers Guide is posted and the odometer is disclosed. The paperwork is treated like a gate because it is one.

The desk and the ups

Leads and ups to work, deals desked, and the one sold without the title in hand.

Finance and products

Back gross booked on every deal, and the store gross across the deals delivered this week.

Online sales

Online deals with a deposit down, from the listing to the delivery, in the same desk.

This is the real system running in your browser, not a slideshow — everything you type stays on your device and nothing is uploaded. It opens on a realistic sample lot; the ribbon at the top clears it so you can enter your own. 4barrel OS is a white-label build by Accelerated Experiences LLC. Nothing here is legal, tax or compliance advice; the FTC Buyers Guide is yours to post.
