What I make for you.
From logo to web shop. My strongest suits: web shops, automating work with AI, and getting found in Google and ChatGPT.
-
Website
A fast site that turns visitors into customers.
-
Web shop
A web shop that sells. Custom or Shopify.
-
Automation
Repetitive work that does itself. You approve everything before it goes out.
-

Automation
Time back.
Typing up quotes, calling back voicemails, hunting for receipts. I connect the apps you already use so that happens by itself. You keep the final say.

Hi Marius, I need a web shop for my business. Can you do that?
Yes. Tomorrow you get one fixed price and one delivery date, in writing.
Agreed. When do we start?
Now. Live on the agreed date.
Marius Kerkvliet.

Questions.
Not listed? Ask via the form.
How do I know the price will not creep up?
Because it is not an estimate. You get one amount in writing before I start, and that is what the invoice says. I do not bill by the hour: overruns cost me time, not you money.
How do I know it will not drag on for months?
The delivery date is in the quote, so it is a promise. A website takes one to two weeks, a web shop two to three, an extension three to five, an app three to six. You see the work along the way.
What do you need from me to start?
A few lines about your business and what you want. That is all I need for a price and a date.
What happens after it goes live?
The site is yours. Domain and hosting are in your name, so you are never tied to me. Maintenance is a small fixed monthly amount, cancel any month. If you leave, I hand everything over for free.
When do I pay, and what if it goes wrong?
Half at the start, half at launch, with fourteen days per invoice. No subscription, nothing afterwards. If you stop halfway, you pay only for what is finished and keep what is already there.
Tell me what you need.
Within one working day you have a fixed price and a delivery date, in writing. No sales call.
Thank you.
You will hear from me within one working day, with a fixed price and a delivery date.
