Software that moves
your business forward.

Software engineering in Dübendorf, just outside Zürich. We start with your business model, not with the design: custom made, never from a website builder, at a fair fixed price. Projects in four countries, from the website around the corner to the tenant management system of the largest property management company in Serbia, with more than 600 buildings.

// What we do

Everything your business
needs online.

From what your customers see to the software running behind it: we build both. First we work out how your business creates value for your customers, then we build the software around that. Clean code, a modern stack, all of it in-house. Modular, so it grows with you: add a shop, add a customer portal. We use AI where it takes work off your desk, and nowhere else.

01

Websites

Company sites that turn visitors into enquiries rather than just looking good. We work out with you who the site has to convince, and build it so a shop, a booking flow or a customer portal can be added later.

  • Design, structure and copy
  • Multilingual, optimised for phone, tablet and desktop
  • An AI assistant that answers questions and collects enquiries
02

Online shops

Selling to consumers or to other businesses. We look first at your order units, your margins and your workflows. We have built both: from configurators for made-to-measure products to B2B portals with tier pricing.

  • Payment handling, including subscriptions and recurring payments
  • Physical and digital products, invoices written automatically
  • AI product search and newsletter integration
03

Mobile apps

Apps for your customers or for your staff: on a phone and on a tablet, in the shop, in the warehouse or out on the road. We pick the technology to fit what you are building, not what we are used to.

  • Runs on all the common operating systems
  • App Store and Play Store submission, works offline
  • Connected to your internal systems
04

Business software

The systems your team works in every day: administration, customer portal, order handling, case management. We look first at how the work actually gets done at your place, then build. No dependence on someone else’s licences and expensive subscriptions.

  • Booking and CRM systems, customer portals
  • Workflows from first enquiry to sign-off, with reporting
  • Integrations with your systems, receipts filed by AI
05

Getting found

We set your online presence up so that search engines and AI put you forward. For busko1828.pl our client now ranks first in Google and in ChatGPT for water from the region.

  • Technical SEO audit and the fixes that follow
  • Google Business Profile, Google Maps, local SEO
  • Findable where customers now ask an AI instead of searching
06

Hosting & support

The site is live, and now what? We host, update and monitor what we build, so that in three years it still runs as fast and as reliably as it did on day one. And we stay personally reachable throughout.

  • Hosting in Switzerland or the EU, domain and email
  • Updates, security patches, backups, monitoring
  • One named contact, usually an answer the same day
// What we build with

Modern tools, proven in production.

Proven, modern tools: the same ones the projects in our case studies are built with and run on today.

  • Next.js
  • React
  • Stripe
  • Google Maps Platform
  • App Store
  • Google Play
  • WhatsApp
  • Instagram
  • + more

Plus the systems you already run: ERP, accounting, CRM, calendars or your warehouse, wired in through their APIs. If it has an API, we connect it.

// About us

We build every project
the way we would build it for our own business.

  1. The beginning

    A handful of side projects

    Bluewall did not start as a company. It started as a handful of side projects. We studied together, and afterwards kept building in the evenings alongside our day jobs for people who needed someone they could trust with their website or their system. At some point there were too many projects for “evenings”.

  2. Today

    Bluewall Tech GmbH, Dübendorf

    Today we are Bluewall Tech GmbH, based in Dübendorf just outside Zürich. Since then we have worked in Switzerland, Serbia, Italy and Poland: from a website for a studio around the corner to the management system for the largest property management company in Serbia, with more than 600 buildings. Our years in startups taught us what an offer needs online before it gets found and bought.

  3. What stays

    The same people at the table

    Whoever sits at the table in the first meeting is also the one who writes the code later. We keep asking until we understand how your business works, and we say so when something you asked for will not do anything for you. Pragmatic, but no compromise on quality. And whatever we do not do ourselves, we tell you and bring someone in from our network.

At home in Zürich, working across Europe.

Meet the team
// What that means for you
Short paths, fast answers

One named contact, reached directly by email with no account manager in between. Usually you get an answer the same working day. And because we are based in Zürich ourselves, we are glad to come by for a conversation.

Custom built, not off the shelf

No website builder, no bought template with your logo dropped in. You get something that fits your business and that belongs to you.

We think with you, not just build to spec

Before we build, we want to know where your money comes from and what is getting in the way today. Sometimes the answer is a smaller thing than the one you asked for.

// Work

What we have worked on.

Three projects from three countries: from the website around the corner to the system an entire company works in every day.

A redesign in a galactic look, matched to the interior of the practice.

A local business in Dübendorf came to us about its website. Website and email migrated off the old provider, appointment booking and WhatsApp wired straight into the page, and Instagram posts running along automatically. Plus SEO for Google Search and Google Maps.

Outcome
More online bookings from launch, as reported by the client

PROPERTY MANAGEMENT · BELGRADE
Mobile appManagement systemCase handling

A tenant portal, a flat management system and complaint handling for the largest property management company in Serbia, with more than 600 buildings.

Tenants see announcements and the status of their own reports in the app. The office keeps addresses, flats and responsibilities in one system, and every complaint runs from filing to sign-off through the same traceable workflow.

Outcome
600+ buildings and 5,000+ flats in one system

Talk to us about your project
// Frequently asked

What business owners
ask us most often.

Why bother with a new website at all?

What our clients report after launch: more enquiries and more sales, because the site actually leads visitors towards contacting them. On top of that they are easier to find, because we build SEO in from the start, in Google Search and on Google Maps, which is where local customers look first. And then the obvious things that are so often missing: it works on a phone, it loads fast, and it looks like a professional business you can trust.

How does a project run with you?

First a conversation in which we ask more than we talk: where your money comes from, who buys from you, what is getting in the way today. Out of that we write down what we would build, in what order, and what it costs. We start only once that is settled. After that you follow the progress on the running site rather than in a status report. And if something you asked for will not do anything for you as far as we can see, we say so before you pay for it.

How long does a new website take?

A company website: roughly three to five weeks. An online shop: six to ten. An app or a custom system depends on the scope, which we agree with you beforehand. The most common cause of delay is not us, it is content: copy, photos, product data. We tell you on day one what we need from you, and we will write the copy with you if you want.

What does it cost, and how do you bill?

A fixed price. After a conversation and a short scoping pass, you get a written quote: one price, and a list of what is included. No billing by the hour, no add-on invoices for small things. In most cases you have the cost in writing before we start, so there are no surprises. If the scope changes materially along the way, we tell you before we do it, not afterwards on the invoice. Work you did not ask for never appears on a bill from us.

Can you host in Switzerland?

Yes. Our default is a Swiss data centre, including domain, certificates and email. EU hosting, or running on your own infrastructure, is equally possible. We set it up so that you can comply with the Swiss FADP and the GDPR, and we tell you which data sits where. If you ever want to move: the code and the data are yours, no argument.

Do we need AI, and where does our data end up?

Sometimes yes, often not yet. AI earns its place where it measurably takes work away: an assistant on your site that answers customer questions from your own content and hands over when it does not know. A product search that understands what was meant. Receipts and emails that file themselves instead of being re-keyed. Where it does not pay off for you, we do not build it in. Your data sits in Switzerland, in the EU, or entirely on your own infrastructure; we set that boundary with you before anything is connected.

What does support look like once the site is live?

Your site going live is not the finish line. A monthly maintenance agreement covers hosting, updates, security patches, backups and monitoring, plus smaller changes as you go. You get one named contact you reach by email, no ticket system and no queue. If something breaks, you hear from us the same working day. And if you do not want the maintenance, it will not be pushed on you.

Can we still have things changed after launch?

Yes, at any time, including months after sign-off and payment. There are several hosting packages, and in most of them smaller changes are already covered by the monthly fee: new opening hours, another team member, an extra service on the page. Anything beyond that comes with a price before we start. You write to us with what should change, and you hear back what it costs and when it will be done. And if the website should later become a shop or a customer portal, we build on what is already there instead of starting over.

Do you work with WordPress or a website builder?

No, we build custom. That is why our sites are fast, do not carry twenty plugins that break each other on update, and have no licence that creeps up every year. You pay once, for something you own. If an existing platform genuinely is the more sensible choice for your case, we will tell you that too, rather than selling you something.

We already have a website. Would you take it over?

Yes. First we look at it: speed, findability, security, how current the technology is. Then we tell you whether a rework is worth it or whether rebuilding is cheaper than repairing. Often the rework is enough. And if you are happy with the site itself, we are glad to take over only hosting and maintenance.

Do you work outside the Zürich area?

Our focus is Switzerland, and we are open to projects abroad as well: we have worked in Serbia, Italy and Poland, largely remotely, with time on site where the work called for it. Distance changes nothing for you: the same contact, the same short paths, contract and invoice from Switzerland. We work in German and in English.

Still wondering about something? Write and tell us what you want to know. You will hear from us within 24 hours.
