ISOXRent, also known as ISOX, is a cloud-based management platform designed for car rental businesses. It brings fleet, booking, customer and document management together in one system, helping operators replace spreadsheets and paper folders with a shared, organized workflow. The software supports businesses of different sizes, from small fleets to multiple branches.

Rental teams can record vehicle details, photos, categories, daily prices, mileage, registration dates and locations. Bookings are checked for conflicts for each car, preventing overlaps while allowing same-day returns and pickups. The platform also supports customer records, handovers, deliveries and vehicle location tracking across branches.

ISOXRent generates rental agreements and invoices as PDFs using customizable templates, including business logos, text, serial numbering and document language. Analytics help users review monthly revenue, popular vehicles, top earners and seasonal demand. Service tracking records maintenance such as oil changes, tire work, brake repairs and inspections, with mileage and costs; the dashboard can flag upcoming service needs. The interface is available in English, Macedonian, Albanian and Turkish.
