Rechnungstool Campinghof - Rechnungen als PDF statt Excel-Vorlage
Desktop-Programm (Python/Tkinter): Kundendaten + Leistungen eingeben, druckfertige PDF-Rechnung im Briefkopf des Betriebs. Optionale Beherbergungssteuer wird eigen ausgewiesen und bekommt ein zweites Blatt fuers Amt. Firmendaten, Preise und Steuersaetze stehen in der config.json neben dem Programm (nicht im Repo) und werden im Menue "Einstellungen" gepflegt. Im Code stehen nur Platzhalter.
