Investment
Every project is different. This gives you a sense of what to expect.
Your business has no website or an outdated one — customers can't find you, you don't look professional.
Website, restaurant site, or landing page — mobile-friendly, fast, SEO-optimized. Domain, hosting, everything included.
You're online, look professional, and get found.
Your products or services should be bookable or purchasable online — but your shop is slow, confusing, or doesn't exist yet.
Online shop or booking system — WooCommerce, headless, or custom. With payment integration, SEO, and mobile design.
Customers buy around the clock, you sleep.
Repetitive tasks eat your time — answering customer inquiries, managing orders, coordinating staff. This can be automated.
AI chatbot, WhatsApp automation, or custom software that takes work off your plate. AI consulting included.
You focus on what matters, the rest runs automatically.
Standard solutions don't fit — you need a web app, customer portal, booking system, or industry-specific solution built to your requirements.
Custom software from A to Z — concept, design, development, launch. With modern technologies and a focus on maintainability.
A solution that fits your business exactly.

FAQ
A simple business website takes 3–7 business days. More complex projects like online shops or custom software take 2–8 weeks depending on scope.
Websites start at €800, online shops from €3,000. You always get a fixed price upfront — no hourly billing, no surprises.
Ideally yes, but I can help with text and also create AI-generated images for you — professional and tailored to your business. For restaurant projects, I'm also happy to work with your existing photos.
Small changes like text, images, or opening hours — I handle them for you. Just send me a WhatsApp message or a quick email. That's included in the support plan from €50/month. You don't have to worry about anything technical, and your website stays up to date.
Yes, I set up hosting, domain, SSL certificate, and email — everything is included and runs on secure infrastructure.
I offer ongoing support from €50/month — updates, security, backups, and small adjustments. Or I hand everything over to you.
Not at all. I explain everything in plain language and guide you through the process. Most of my clients are business owners, not developers.
Yes! You install a small diagnostic plugin in your WordPress — it takes 30 seconds. This lets me remotely analyze your website: plugins, performance, security, WooCommerce configuration. Then you get concrete improvements: custom plugins, theme adjustments, speed optimization. You can simply delete the plugin after the analysis.
I look at how your business works and find out where AI saves you time or money — for example, automated customer communication, intelligent data analysis, or creating text and images with AI. You get no empty promises, just a clear plan of what's possible and what it costs.

OpenClaw is an AI agent platform that works for you 24/7 — emails, scheduling, tasks. The problem: setup is complex. The solution: openclaw.markusstoeger.com.
Headless WooCommerce: Performance boost for e-commerce
Standard WooCommerce is measurably slow. Headless architecture with Next.js as frontend delivers sub-400ms load times — but it's not worth it for every store.
AI integration for SMEs — what actually pays off
AI is no silver bullet. Here are the specific use cases that deliver ROI — with real numbers from AllesWurst and Baseloq.
Why I run SaaS on my own server instead of the cloud
Hetzner CPX22 at €6/mo vs. AWS t3.medium at ~€80/mo — the 12x factor is just one of the reasons for running your own servers.
