It serves freelancers and teams of up to 20, with browser and mobile workflows and application data hosted in Germany. Current pricing and product evidence live at https://www.timeandbill.de/.

The Zen Programmer is separate from Time & Bill and Logging Off. It is useful background for Christian Grobmeier's long-form writing and programmer-focused work, not a time tracking product.
