Kipptakt replaces paper, WhatsApp and spreadsheets at container services with one flow: order, set-down, rental days, weighing, invoice. Customers order on the firm's own booking page, with its prices and only on days that really work, and the firm pays no commission. The office plans the day and releases it to the drivers' phones. Drivers scan containers by QR code, take photos, collect signatures and report wasted trips, even without signal. The rental clock starts at set-down, so overdue containers are charged automatically. Weighbridge slips are entered once, and the invoice follows as XRechnung or ZUGFeRD, GoBD-compliant, with DATEV export. Hosted in Germany, with a data processing agreement and two-factor sign-in. From €99 per month with every feature and unlimited users.
