Product & Service Introduction:
===============================
INET-CASH ist im Bereich des Online-Payments seit 1995 aktiv. Sie erhalten hier einen kompletten überblick über unser Angebot,
das die gesamte Abwicklung aller relevanten Online-Zahlarten, mit einfachster Anbindung an Ihr System, umfasst. Es bildet ein
lückenloses System von Lösungen für die Abrechnung von Memberbereichen über diverse Lösungen für die Abrechnung von Online-Shops
bis hin zu Individual-Lösungen, die keine Wünsche mehr offenlassen. Egal, für was Sie sich entscheiden, unsere Lösungen sind so
sicher, wie Sie es sich wünschen, denn wir entwickeln seit Jahren Sicherheitskonzepte, die nicht nur das Wort sicher im Namen
tragen, sondern es auch sind. Im Branchenschnitt unterdurchschnittliche Storno-Quoten geben uns Recht, diesen Weg kontinuierlich
beschritten zu haben. Dass Sie Ihre Transaktionen in Form von umfangreichen Statistiken abgebildet bekommen, ist zwar für uns eine
Selbstverständlichkeit, sei aber an dieser Stelle noch einmal explizit erwähnt. Ebenso tragen wir dem Umstand, dass im Internet
vielfach Kooperationen in Form von prozentualen Umsatzbeteiligungen eingegangen werden, dadurch Rechnung, dass sämtliche Systeme
von uns affiliate-fähig sind. Dies beinhaltet sowohl die Umsatzzuordnung inkl. der Abbildung der Umsätze in Statistiken als auch
die Abrechnung Ihrer Partner.
