Your business in hand, even when you're away from the office.

We look at how work gets done at your company, connect the systems you already have and take the simple office tasks off your team's plate. You make the decisions.

From Saarbrücken, for businesses in Saarland and beyond.

Where does work get stuck?

Start with the problem. We find the right path: consulting, a product or a custom implementation.

Your systems need to work together.

Duplicate entry, Excel workarounds and handovers between tools? We develop suitable software, connect interfaces and simplify workflows.

Explore software & integration

Office work gets left behind.

Calls, emails and documents wait until evening? Griffi captures enquiries, organizes them in a case and prepares drafts for you to review.

What is already documented.

92% less time on receipt work

One pilot client compared their receipt work before and after: from around two hours to ten minutes. Self-reported, rounded and not independently measured.

You can try the e-invoice validator yourself.

Choose an XRechnung or ZUGFeRD file and see which mandatory details are missing. The check runs in your browser and the file never leaves your device.

“For ten years I built software for large companies. With n3tz I build it for businesses like the one my mum works in.”

My mum has worked in the office of a trade business for 30 years. Much of what piles up there is stuck between the phone, paper and programs. That is where we start: with a product like Griffi, an integration or an application of your own. You make the decisions and give the approvals.

How we help your business.

Three steps, one contact person. You see early what is being built and decide yourself what goes into your daily work.

  1. Tarik Ermis speaking into the microphone at the Startup Launchpad Demo Day 2026

    We look at how your work runs.

    On site or in a conversation: who does what, where work piles up, which systems you already have.

  2. Griffi Zentrale on a phone, German interface: an offer draft for Fischer Bäckerei GmbH, 4th branch, at 1,124.55 euros gross, with the buttons “Bearbeiten” (edit) and “Entwurf löschen” (delete draft)

    We build what is missing.

    An n3tz product like Griffi, a connection between your systems or an application of your own. The task decides.

  3. Griffi Zentrale on a phone, German interface: a call about adding a fourth branch to a maintenance contract, below it the next step (decide whether to accept the request) and the result “Anfrage aufgenommen” (request recorded), numbers masked

    You approve, we keep it running.

    Nothing goes out without your approval. A pilot with agreed measures shows what holds up, and we stay available for maintenance, knowledge transfer and the next step.

Decisions from real projects.

Read the n3tz blog

On the blog we write down how we made decisions in software and office projects and where the technology reaches its limits.

New tools for your office, now and then by email.

When we publish something that takes work off your hands, like the e-invoice validator, you get a short email. No fixed schedule, and we never share or sell your address.

Let’s talk about your business.

I’ll get back to you personally. Tarik Ermis, founder of n3tz
