Schwarzbuch digital web application: research and information on tax waste in Germany, modern in-browser experience (React)

Schwarzbuch digital

We build the “Schwarzbuch digital” web application: a digital “black book” that presents researched cases of tax waste in Germany in a clear, analytical form. The goal is a fast, reliable, and easy-to-read browser experience for complex material—delivered as a modern React single-page application by Groenewold IT Solutions in Leer/East Frisia.

Web platform & research

The Challenge

Complex material, clear reading

Tax waste content is challenging: many facts, multiple levels (budget, processes, policy), and the expectation that citizens can orient themselves quickly. The task was to structure the material so research and analysis stay visible while the UI remains navigable—especially on mobile devices.

The application also needs a fast first load, smooth scrolling, and consistent navigation. Transparency work depends on trust, and trust depends on solid technical delivery—not decorative noise.

A web-native publication, not a static-PDF afterthought

A “Schwarzbuch” must stay current and discoverable. Rather than locking knowledge into static documents, we needed a web format where cases are accessible, comparable, and expandable over time—requiring solid information architecture, reusable UI building blocks, and a clean separation of content, layout, and delivery.

Our Solution

Web application as a React SPA

We implemented the platform as a React single-page application: clear routing, quick interactions without full page reloads, and a front end aligned with typical research and reading patterns. TypeScript and a disciplined component model help keep content and UI consistent as the topic set grows and copy evolves.

Delivery is optimised for lean assets and good load times so information is not held back by technical friction.

Engineering by Groenewold IT Solutions (Made in Germany)

Development, architecture, and evolution are led from our team in Leer (East Frisia): short communication loops, traceable quality, and a maintainability mindset—so custom software can remain operable, not just demo-ready.

Results

A public research and information resource on the web

At schwarzbuch.digital, the application presents documented cases in an accessible way and supports a traceable, journalistic perspective on tax waste in Germany—without sacrificing readability for depth.

Reference for research-driven web platforms

The project shows how we translate content with public and political relevance into a professional web application when off-the-shelf CMS or no-code approaches hit limits—prioritising clarity, accountability in delivery, and B2B-style engineering from Germany.
