Bookingtime

What Bookingtime does

Bookingtime GmbH is a Hamburg-based, privately held German SaaS company founded in 2006 that provides online appointment scheduling and room booking software under a dual-tier model. Its Business Solution targets small businesses, solo practitioners, and SMEs through a product-led self-serve funnel with a quick 3-step setup, free trial, monthly subscription billing, and CMS plugins for WordPress, TYPO3, and Joomla; over 15,000 customers are cited. Its Enterprise Solution targets DAX-listed corporations, large enterprises, government agencies, and third-party integrators through direct sales with multi-year contracts, custom pricing, and dedicated consultation.

The core technology is a 100% API-based cloud platform that handles real-time appointment booking with automatic resource blocking, multi-channel notifications (email/SMS), bidirectional calendar synchronization with O365, Google Calendar, and iCal, video conferencing integration with Zoom, Google Meet, and MS Teams, event and course booking, analytics integration, and white-labeling. Enterprise-specific capabilities include SSO/OAuth authentication, role-based access control, dedicated developer documentation, reporting dashboards, GDPR consulting, and Follow-the-Sun global scalability.

The business model is subscription-based recurring revenue split across SMB and enterprise tiers. The company monetizes SMBs through monthly self-serve subscriptions and enterprises through multi-year custom contracts, supplemented by API/white-label OEM embedding for technical service providers. It operates ISO/IEC 27001-certified infrastructure hosted on AWS with servers located exclusively in Germany and Europe, GDPR/DSGVO and BDSG-new compliance, and EU-US Data Privacy Framework certification. The company was rebranded from onlinetermine to bookingtime in March 2024, with three Managing Directors (Lars Borggräfe, Oliver Fürstner, Dennis Kokot) and a designated data protection officer.
