Hi, I'm Marco.

I build profitkonsole.

For many years I have been building interfaces and platforms in e-commerce: EDI, REST‑APIs, marketplace integrations. The very pipes that orders, fees and returns flow through.

At some point I was looking at a catalogue with hundreds of variants per item and one simple question: what is actually left after commission, shipping, advertising and returns? For OTTO there was no clean answer. So I built one.

What has happened since

1. Autumn 2025

   The first line of code. The goal: the real contribution margin per item on OTTO.

2. March 2026

   profitkonsole launches for OTTO sellers.

3. July 2026

   Cortex, the AI assistant for your numbers. Plus advertising costs per item and automatic email reports.

4. October 2026

   The Shopify app is approved, and profitkonsole is listed in the Kaufland Technology Partner Network.

5. Today

   OTTO, Amazon, Kaufland, eBay, Shopify, bol.com and Temu in one multichannel dashboard.

Always in touch

More than 70 sellers have connected profitkonsole, and I am in direct contact with every one of them. No ticket system, no queue: you write, I read and reply, within 24 hours.

What sellers need goes on my list, and much of it shows up in the changelog soon after. That is how profitkonsole came about, and how it keeps growing.

What's next

• More integrations

  More marketplaces and ad platforms, each with its own billing logic, broken down cleanly to the contribution margin.

• profitkonsole on your phone

  Your numbers as an app, without a detour through the browser.

• What you ask for

  Sellers help write the list. If something is missing, email me.

Your data: profitkonsole connects through the marketplaces' official interfaces, and you can revoke access at the channel at any time. I don't sell data or pass it on for advertising.
