Prezentacja
by Jan Kononowicz
Dzień dobry!
Czy mógłbym przedstawić rozwiązanie, które umożliwia monitoring każdego auta w czasie rzeczywistym w tym jego pozycję, zużycie paliwa i przebieg?
Dodatkowo nasze narzędzie minimalizuje koszty utrzymania samochodów, skraca czas przejazdów, a także tworzenie planu tras czy dostaw.
Z naszej wiedzy i doświadczenia korzysta już ponad 49 tys. Klientów. Monitorujemy 809 000 pojazdów na całym świecie, co jest naszą najlepszą wizytówką.
Bardzo proszę o e-maila zwrotnego, jeśli moglibyśmy wspólnie omówić potencjał wykorzystania takiego rozwiązania w Państwa firmie.
Pozdrawiam,
Jan Kononowicz
