Frequently asked questions

Everything you need to know - answered transparently and in detail.

How much does a website cost?

From 3,600 € net for the custom-built website, payable either all at once or in twelve monthly instalments of 300 € net - both ways cost the same. From go-live the care contract is added: 49 € net per month for hosting and technical maintenance. Paying in instalments, you therefore pay 300 € net per month until go-live and 349 € afterwards; after twelve months the website is paid off and only the care contract remains. Later changes are billed one by one, by effort.

How long does a project take?

The standard package goes live in two to three weeks, counted from content approval. Larger projects take two to eight weeks depending on scope. We define the exact timeline together during the planning phase.

Is the first call really free?

Yes, absolutely. The 30-minute first call is free and non-binding. We'll discuss your project, give you an honest assessment, and you can decide at your own pace whether you'd like to move forward.

How is my website found in ChatGPT, Perplexity, and Google AI Overviews?

Three levers: first, structured data (Schema.org) for Organization, Service, FAQ, and Reviews - industry data shows 65-71% of AI citations contain structured data. Second, a clean semantic HTML hierarchy with real Q&A formats - FAQ schema has the highest citation rate (around 67%). Third, a clean robots.txt with explicit allow directives for the important AI crawlers (OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended). We build all three levers into every website - it's standard for us, not an upsell.

What does the collaboration process look like?

After the first call we agree the scope, the fixed price and the timeline together, and the price does not change after that. During development, you'll receive regular updates and milestone reviews so you're always in the loop. The project ends with your acceptance and the go-live.

What happens after launch?

With go-live the care contract starts as a separate agreement: 49 € net per month for hosting and technical maintenance. When you pay in instalments it is a fixed part for as long as the instalments run; after that it can be cancelled with four weeks' notice to the end of a month. With the one-off payment it is optional and can be cancelled on that notice from the start. Changes to text, images or structure are billed one by one, by effort; anything above two hours gets a quote of its own first.

What if I don't like the result?

Through regular check-ins and milestone reviews, we make sure the direction is right. Feedback is incorporated at every stage.

Why Heistermann Solutions instead of a large company?

You work directly with the developer - no middlemen, no overhead costs. Every project gets our full attention.

Which technologies do you use?

Our core stack is Next.js, React, TypeScript, and Tailwind CSS for the frontend, with Node.js, Python, PostgreSQL, and Supabase for backend tasks. That's just a snapshot - depending on your needs, we also work with other tools and frameworks. You can find a broader overview on our Tech Stack page, and we'll discuss the specific choices for your project in the first call.

How do we communicate during the project?

Video calls for milestone reviews and kickoffs, asynchronous communication (email, Slack, or your preferred tool) for daily updates. We typically respond within 24 hours on business days.

What about data protection and GDPR?

Every project is built GDPR-compliant. This includes cookie consent banners per German Federal Court standards, privacy-first forms, privacy by design, and a legally compliant privacy policy. Servers are preferably located in the EU.

Do I own the code after the project?

Yes. With the one-off price, you receive an exclusive, perpetual and transferable right of use in the website - source code, design and content - on final payment, including the right to modify it and have it modified by third parties, plus the complete source code, the documentation and all access details. With instalments, a simple usage right for operating your website applies from go-live; the full transfer of rights and the source code follow with the last instalment. In practice, either way: once it's paid off, you can carry on freely, with other developers too. The only exceptions are our cross-project building blocks and open-source libraries, which stay under their own licences.

Can you migrate my existing website (e.g. WordPress)?

Yes, in most cases. Whether a 1:1 migration, a relaunch on your existing domain, or a complete rebuild is the better path depends on the state of your current site. We'll evaluate that together in the first call - and you'll get an honest recommendation on which way makes most sense for you.

What if I need larger changes a few years down the road?

Once the website is fully paid off - with the final payment or the last monthly instalment - all usage rights and the complete source code are yours, along with the documentation and the domain in your name. For larger changes you can either continue working with us (depending on capacity) or with another developer familiar with the modern tech stack. That's exactly why we build on established technologies like Next.js and React: so your site remains maintainable and extensible years later.

What happens if you're unavailable during the project?

A fair question when working with a single developer. In practice, every project has milestone commits and documentation, so the current state is always transparent. If we are unavailable for longer, you can either wait for us or seamlessly continue with another developer - once the website is fully paid off, the usage rights and the source code are yours.

Will you make sure my website gets found on Google?

Technical SEO is included in every project: clean structure, fast loading times, mobile-first, structured data, and sitemaps. That's the foundation so Google can properly rank your site. A long-term content and keyword strategy is a separate topic - if you need support there, we can discuss it in the first call.

Who writes the copy for my website?

The content is created together. You give us the input, since nobody knows your business better than you, and we bring the copy into shape: clearly structured, easy to follow and written to be found and to bring in enquiries.

Next.js, React, WordPress - which technology is right for my website?

It depends on use case, content workflow, and long-term extension needs. WordPress is cheap to start with but maintenance-heavy long-term due to plugin updates and security patches. Modern frameworks like Next.js and React offer better performance through pre-rendering, higher security with no plugin attack surface, and cleaner structured data for SEO and AI findability. Which stack fits your project best is something we'll work out together in the free first call.

Why pay in monthly instalments instead of a one-off invoice?

The monthly instalment lowers the entry barrier significantly compared with one large invoice, and you pay exactly the same price as with a one-off payment - no surcharge, no discount. After the twelfth instalment the website is fully paid off, and you receive the exclusive, perpetual right of use and the complete source code. What remains is the care contract, not a payment plan that just quietly continues.

What happens after the twelve monthly instalments?

With the final instalment the website is paid off. You receive the full, exclusive usage right and the complete source code. All that remains is the care contract: 49 € net per month for hosting and technical maintenance - from now on cancellable with four weeks' notice to the end of a month. If you do not want the care contract, simply give notice and take the website, the domain and the source code with you.

Can I pay once instead?

Yes, and both ways cost the same. The fixed build price from 3,600 € net is due either all at once or in twelve monthly instalments of 300 € net - no discount and no surcharge. With a one-off payment you receive all usage rights and the source code on final payment; with instalments, on the last one. The care contract at 49 € net per month is optional with the one-off payment; with instalments it is a fixed part for as long as they run.

Are the prices net or gross?

All prices shown are net, plus 19% VAT.

What do changes cost after go-live?

Changes are billed one by one, by effort; there is no package you have to keep booked for them. Small adjustments are implemented and the actual time is invoiced. Anything beyond two hours gets a quote of its own first - you know the price before we start. If you have changes on a regular basis, ongoing support can be arranged with us on request.

What's not included in the price?

Everything your website needs to launch is included - from development to the technical SEO foundation. Later content changes are billed one by one, by effort. Separate services such as ongoing SEO, GEO, content marketing, or automation build on top of that and are quoted individually, tailored to your project.
