Two Divisions.
One Vision.

Hirschmann & Koxha works across two worlds united by the same standard: complex processes must remain precise, traceable and manageable – in automotive work as well as in legal tech.

Legacy Division

HK One

Every tool. One place.

Our Legacy division has spent years around Saabs, and every year of that ended up as scattered documents, catalogues, self-built tools and half-remembered tricks. HK One is where we put it back together: one dashboard, one interface, on one server.

Saab workshop data and parts catalogue, side by side.
Search by fault code, bulletin or part number, with exploded views and position markers.
Read, edit and flash CIM EEPROM dumps straight from the browser.
Built to grow. Further tools join the same dashboard over time.

HK One

The workshop platform

WIS, EPC and the CIM Tool under one roof, in your browser, on one server. Nothing to install, and it grows as we add tools.

HK LUMO

Light without the drama

Removes the halogen check from the Saab 9‑3II, so LED and xenon run without flicker and without SID warnings. One tool, one click.

A connection is either correct or it is not. A task was completed and documented – or it was not.

With TaxTronik, we apply this way of thinking to tax-firm processes: bring information together, expose risks and keep decisions traceable.

Do not guess. Do not hope. Trace it.

From matter to evidence

Software structures. People decide. The process remains traceable.

Connect

Information stays with the client record.

Structure

Tasks, deadlines and responsibilities work together.

Control

Risks and professional decisions become visible.

Trace

The Audit Chain keeps the process explainable.

Same DNA. Sharper focus.

One half has been doing this for more than half a decade. The other half is just getting started. Both carry the same Hirschmann & Koxha commitment to quality, transparency and long-term partnerships.
