Building the DMS dealerships actually deserve.
ARSIN is an AI-native Dealer Management System for the U.S. market — one connected platform across Sales, Service, Parts, and Accounting, with Nova as the intelligence inside the machine.
The problem we started with.
Most U.S. dealerships still run on legacy DMS platforms stitched together with integrations. Data gets re-keyed between Sales, Service, Parts, and Accounting; month-end becomes a reconstruction. We think dealers deserve software that works the way their store actually does.
Our mission
Replace the aging, disconnected stack most dealerships run on with one modern, AI-native platform — so every department works from the same real-time truth.
Our vision
An intent-first dealership: your team describes the outcome and Nova handles the work across any role — within permissions, fully audited. Classic UI stays as a fallback.
What breaks in a legacy DMS.
Data re-entry between departments
Deals, ROs, parts, and journal lines re-keyed between systems. Different numbers in different reports, every day.
Reports that lag reality
Front-end activity doesn't post until a nightly batch. Managers run the store on numbers hours or days behind the room.
Software you have to memorize
Every job lives at a specific menu path. New hires take months to be productive; experienced staff can't easily cover other roles.
Audit trails scattered across vendors
No one picture of "who did what, when" across Sales, Service, Parts, and Accounting — especially for AI-assisted actions.
Change is painful
Adding a department or a rooftop means another integration, more re-keying, and more month-end variance.
Service & Sales out of sync on trades
The desk often works with stale recon estimates — the real recon picture lives in a different system until it's finally posted.
