Auto555

Auto555 is a web CRM for car rental businesses. We build it at Levitsky Concept to help rental teams keep their fleet, customers and bookings in one workspace. This is a car rental product: availability and booking periods are central to the workflow. The free plan supports up to five cars and one user. The application interface is in Russian. A public demo lets visitors explore fictional fleet and booking data before registering. That demo is read-only; it does not expose a real rental company's customers or change live bookings. We have also published a free browser calculator for rental utilization. It separates calendar days from days when a car is available, so maintenance or preparation time is not silently treated as rental capacity. Users can compare booked days, daily rates and entered costs, then export the calculation as CSV. Inputs are processed locally in the browser; the calculator does not connect to the CRM. It is a planning aid, not accounting software or a promise of profit. Another public resource is a spreadsheet for organizing rental records. The website includes a practical guide to overlapping bookings and preparation time between rentals. These resources can be tried independently of creating an Auto555 account. Our marketing site and application use Next.js. The useful design question for us is how to keep a small rental team's first steps straightforward while making the meaning of availability clear. Explore the demo or the free resources from the product website. We welcome specific feedback about the rental workflow.
