Extensions, plugins and software around JTL
JTL plugins and Wawi extensions, exactly the way you need them.
What JTL cannot do, I build on top.
JTL plugin development for shop plugins and Wawi extensions: when the standard reaches its limit, I build the missing function instead of bending your processes to the software. You keep your JTL but get what was missing.
Whether a plugin for JTL-Shop, an extension for JTL-Wawi or the software around it that connects your systems: all from one source, with code that is yours in the end.
Development, not support
I do not offer classic JTL support. For setup, daily use and questions about the standard, your JTL service partner is the right contact.
I start where the standard ends: extensions for JTL-Wawi, plugins for JTL-Shop and custom software around JTL that brings Wawi, shop and your other systems together cleanly.
I know the JTL ecosystem from daily work: JTL-Wawi integrations, automating production shipping and contributing to one of the larger German online shops in my industry. On top of that, NZ GEO Visibility is a plugin I develop and sell myself.

Plugins for JTL-Shop
If your shop should do something that does not exist yet, I build it as a custom plugin for JTL-Shop 5. Cleanly encapsulated, without touching the template and update-safe, instead of spreading changes all over the shop.
The data comes from the source you already maintain: your JTL-Wawi. So you never enter anything twice.
Pitfalls of JTL plugins
My own plugin
NZ GEO Visibility
My own plugin makes your shop fully visible to AI search engines such as ChatGPT, Perplexity, Claude, Gemini and Google AI Overviews. Every page gets its own .md and .json version with prices, stock and variants, one to one from the shop.
The plugin writes your robots.txt: you can allow or block AI bots individually and see in the statistics which bots visit your pages and when. Your own entries stay untouched.
First result: no citations in ChatGPT and co. before, then around 30,000 AI and bot requests in the first week.

AI revenue per assistant
Visibility alone is not enough, revenue is what counts. The AI revenue area in NZ GEO Visibility shows which AI brought customers to you and what they bought: revenue, orders, conversion and order value per AI assistant.
So you see in black and white whether AI visibility really pays off for your shop, instead of just counting requests.

JTL-Wawi extensions & workflows
When the Wawi does not cover a step your workflow needs, I build the extension for it. For example a module that puts quotes and orders straight from the shop into the Wawi, as if a real user had created them.
I automate recurring steps with JTL Workflows: sending invoices by email, forwarding orders, enriching data via SQL. Where plugins and workflows are not enough, I work cleanly directly on the JTL database (Microsoft SQL Server), for reports and processes the standard does not offer.

Connect systems
Software around JTL
Often the problem is not JTL itself but what lies in between: data moved by hand between Wawi, shop, marketplaces and your own systems. For that I build integrations and custom software that close the gap.
From practice: automating production shipping with a JTL-Wawi integration, so orders flow from the system into shipping without manual steps.

How your JTL extension comes together
-
Getting to know each other
Together we look at what your JTL cannot do today and where time is lost in your workflow.
-
Concept & fixed price
I clarify whether a plugin, a Wawi extension or custom software is the right way. You get a binding fixed-price quote.
-
Development & test
I develop and test before go-live, so your running shop and Wawi are not disrupted.
-
Handover & further development
You get code and documentation. On request I keep developing the solution as your workflow changes.
What does a JTL-Shop plugin or Wawi extension cost?
The price depends on scope, so there is no flat rate. After a short conversation you get a rough estimate, after the concept a binding fixed-price quote. Small integrations start in the low four figures, larger extensions well above that.
You get NZ GEO Visibility and NZ Greenwashing-Check in the JTL Extension Store (NZ GEO Visibility, NZ Greenwashing-Check), each with a 14-day free trial. For adjustments to your shop, just ask.
Request a projectFrequently asked questions
Do you offer JTL-Wawi support or setup?
No. I do not provide setup or user support. I develop: extensions for JTL-Wawi, plugins for JTL-Shop and software around JTL.
How much does a JTL plugin or Wawi extension cost?
It depends on the scope. After a short call you get a cost range, after the concept a binding fixed-price quote. I split large projects into deliverable stages.
Do you also set up JTL Workflows?
Yes. Typical workflows are sending invoices or delivery notes by email, flagging or routing orders by payment method or country, SQL queries to set fields, passing stock and prices to a shop or marketplace, internal notifications and triggering shipping and printing.
What does NZ GEO Visibility do?
NZ GEO Visibility is my own plugin for JTL-Shop 5. It makes your catalog readable for AI search engines such as ChatGPT, Perplexity, Claude, Gemini and Google AI Overviews, with Markdown and JSON versions per page, robots.txt control and statistics on AI bots.
What does NZ Greenwashing-Check do?
NZ Greenwashing-Check is my second plugin for JTL-Shop 5. It checks all shop texts against the 12 rules of the new German UWG and shows risky environmental claims such as "eco-friendly" or "climate neutral" with legal basis, reason and tip. Read-only, no AI, a tool, not legal advice.
What if a plugin is not enough?
Then I work directly on the JTL database (Microsoft SQL Server), cleanly and documented. That enables reports and processes the standard does not offer.
Will my extension keep working after JTL updates?
Yes, I take care of that: everything I have built myself is checked after JTL updates and adapted if needed. I do not maintain JTL-Wawi itself or software from other vendors.
