Sound familiar?
Good work deserves a website that keeps up.
Many businesses around Lake Zurich are excellent at what they do. Online and in the back office, they still lose time and money.
- Your website is showing its age. New clients come in almost only through word of mouth.
- Quotes, invoices and appointments run through Excel, e-mail and the phone. Hours slip away every week.
- Agencies talk in jargon, and the price keeps growing while the project runs.
- That is exactly what I fix. In plain words, at a fixed price.

What your customers never see saves you the most time.
Behind a good website run tasks that someone often still does by hand. I connect the software you already use, so that this work runs by itself.

Work
Built, live and used by real people.
Two of my own products from the Netherlands. Both show what is possible for your business too.
How I work
Clear agreements. No surprises.
Before we start, you know what you get, what it costs and when it will be ready.
01
Call
30 minutes, free
You tell me what you need. By video, and from March 2027 also in person in Höfe and March.
02
Quote
within 48 hours
In writing, with a fixed price, the scope and a binding date.

Every week you see where we stand. One contact, no back-and-forth.
04
Live
on the agreed day
Handover with a short walkthrough. Code, data and domain belong to you.
Fixed price
The price in the quote is the price. No surprises.
Fixed date
A binding date. If I miss it, you get 5% back for each week or part of a week I'm late, up to 20%.
One contact
You always talk to me, never to a call centre.
You own it all
Website, code and domain. No subscription you can't get out of.
Pricing
Published prices. As it should be.
At most agencies in the region you won't find a single price. Here you see my prices before we even talk. As of October 2026, excl. Swiss VAT.
Your contact
I'm Sven Zanstra.
Dutch directness, Swiss precision. I tell you honestly what is worth doing and what isn't.
I build websites and web apps, from the first draft to running them day to day. There are no project managers and no hand-offs: you talk to the person who builds your website, in English or German. “SZ” stands for Sven Zanstra, and it happens to be the abbreviation for the canton of Schwyz too.
Common questions
What clients ask me before we start.
How much does a website cost?
A website with up to 5 pages starts at CHF 3'900.–. A larger website, with the copy written for you and a connection to your software, starts at CHF 6'900.–. After our first call you get a quote with a fixed price. That price stands, unless you ask for extra work later on.
How quickly will my website be online?
Website Start is online in 15 working days, Website Business online in 25 working days. The date is written in the quote. If I deliver late, you get 5% of the price back for each week or part of a week of delay, up to 20%.
Do I have to write the text myself?
No. With Website Business I write the copy for you, after a conversation of about 90 minutes. With Website Start you can supply the text, or I rework your existing copy.
Can I change the website myself later?
Yes. You change text, images, opening hours and news yourself, no coding needed. For bigger changes there is website care from CHF 79.– per month, or you simply ask when you need something.
Do I own the website?
Yes. The code, the content and the domain belong to you. You can move to another provider at any time, with no notice period and no subscription you can't get out of.
What does automation mean in practice?
Work that someone does by hand today runs by itself afterwards. For example: an enquiry on your website automatically becomes a quote in bexio, the Swiss accounting software, or your customers get an appointment reminder the day before. A first workflow starts at CHF 2'900.– and is running after 10 working days.
Can we work in English?
Yes. The call, the quote and the whole project can run in English. Your website can be in German, English or both: a second language adds CHF 1'200.– to Website Start or Business and is included in Website Pro (from CHF 12'900.–).
Do you only work around Lake Zurich?
My focus is businesses in Zurich, Zug, Höfe, March and Rapperswil-Jona. Until my move to the Schwyz side of Lake Zurich on 1 March 2027 we meet by video; after that I'm also happy to come to you. Web apps and automation I build for businesses across German-speaking Switzerland, by video.
Next available start: February 2027
Tell me in two sentences what you have in mind.
You get a reply within 24 hours on working days, and a fixed-price quote with a delivery date within 48 hours of our call.
