Reisebereitschaft
Verfügbar in den Ländern
Deutschland, Österreich und Schweiz
Reisebereitschaft / Remotearbeit
Prinzipiell arbeite ich gerne remote und besuche den Kunden wenn die Arbeit dies erfordert für Meetings und Abstimmungen, wenn dies nicht über Telephon-/Videokonferenzen möglich ist. Hierzu benötige ich lediglich ein stabiles VPN zum Kunden. Glasfaser im SOHO vorhanden. Ich bevorzuge Wien und Umgebung.
Sollte volle vor Ort Tätigkeit notwendig sein so kann ich dies maximal zu 40 Stunden an 4 Tagen die Woche anbieten. Sollte das Projekt länger als 2-3 Monate andauern, so benötige ich 1-2 Remote-Arbeitstage die Woche insbesondere bei längeren Distanzen.
Generell ist weltweiter Einsatz möglich.
Zahlungsmodalitäten
Mein Zahlungsziel auf Rechnungen per Ultimo des Monats ist prompt (best effort), gerne schlage ich 5% auf die Rechnung auf und biete einen entsprechenden Skonto für die schnelle Überweisung, falls dies buchhalterisch notwendig ist.
Im erste Monat biete ich freiwillig eine "Geld-Zurück-Garantie" an: falls der Kunde nach dem ersten Monat nicht vollends zufrieden mit meiner Arbeit/meinem Know-How ist, und danach nicht mehr weiter zusammen arbeiten will, so lege ich keine Rechnung und der Montag war "gratis".
Verfügbarkeit
Generell bin ich sowohl für Volzeit als auch Teilzeit-Projekte Verfügbar. On-demand Dienstleistungeverträge/Bereitschaften sind auch machbar.
