You do not fill in those two lines yourself, and I do not change them afterwards. That is the whole difference with an hourly rate.

How it works

Three steps, and nothing starts until you say yes

You write to me

Tell me in a few lines what your business does and what you want people to be able to do.

You get a price and a date

Within one day you get one fixed price and one finish date, in writing. Nothing starts until you agree.

I build it and it goes live

I build it and show you the work as it grows. On the agreed date it goes live, and I show you how to use it.

What I make

What I make, and what it costs

No project manager, no subcontractor, nobody saying that is not my part. One person designs it, builds it and puts it live. The price and the finish date are agreed in writing before anything starts, and they do not move.

Where I have the most miles: web shops and e-commerce, automating work with AI, and being found — in Google, and in the AI assistants people now ask instead of searching.

Websites

1 to 2 weeks

Clear websites that people actually find on Google. For a business, a club, or yourself.

Web shops

2 to 3 weeks

An online shop where people can easily find and buy your products. I build new shops and improve slow or confusing ones.

Browser tools

3 to 5 weeks, Web Store approval included

Little programs that live inside the Chrome browser and help you while you work. Eight of mine are approved and live in the official Chrome Web Store.

Apps

3 to 6 weeks

Knyaw is my own app for learning to read a language. It works in ten languages, even without internet. I build every app with that same care.

There is no sales call, on this site, and there never will be. You write when it suits you, and within one day there is a fixed price.

Write today, and tomorrow you have a fixed price in writing.

My work

This is what I have made

My own app

Knyaw

A free app that teaches people to read their own language.

It works in ten languages and even without internet. I made everything myself: the design, the app, and the dictionary behind it.

Shop work

Web shop work

Building online shops, and making existing ones better.

The terms

Clear agreements, in black and white

Payment

Half when we start and half when it goes live, with fourteen days to pay each invoice.

Stopping

If you decide to stop halfway, you only pay for the part that is finished and you keep everything I made until then.

Ownership

You are and remain the owner of the website, the content and the data. Everything goes in your name.

Extra work

If you want something that is not in the quote, you get a separate quote for it first. I never carry on unasked.

Questions people ask me

Or simply send an email: hello@murmweb.dev

Do I have to sit through a sales call?

Never. There is no calendar link on this site and there never will be. You write down what you need whenever it suits you, and within one day a fixed price comes back. Everything stays in writing, so you can read it back calmly instead of deciding on the spot.

How do I know the price will not creep up?

Because it is not an estimate. You get one number, agreed in writing before I start, and that is the number on the invoice. I do not bill by the hour, so working longer costs me time, not you money. What it comes to depends on what you need, which is why I ask you to describe it first and then answer within one day.

When do I pay, and what if it goes wrong?

Half when we start, half when it goes live, and you have fourteen days for each invoice. There is no subscription and no hidden cost afterwards. If you decide to stop halfway, you pay only for the part that is finished and you keep everything I have made so far.

How do I know it will not drag on for months?

The finish date is in the same written quote as the price, so it is a promise and not a guess. One to two weeks for a website, two to three for a web shop, three to five for a browser tool, three to six for an app. You can see the work while it is being built, so you are never waiting in the dark.

Who actually does the work?

I do, all of it, from Leiden. There is no account manager between us and no freelancer you never meet. You write to one person and that same person builds the thing.

Can I see something you made first?

Yes. knyaw.app is live for anyone to try, and my eight browser tools are in the Chrome Web Store.

What happens after it goes live?

The site is yours: the domain and the hosting are in your name, so you are never tied to me. If you want me to keep the technical side safe and up to date, that costs a small fixed amount per month and you can stop any month. If you leave, I hand everything over free of charge.

I am not good with computers. Will I feel stupid?

No, and you will not be made to feel it either. You describe what you want in ordinary words, the way you would explain it to a friend. I handle every technical decision and I never send you a message full of jargon. When it is done I show you how it works, in the same plain language.

For agreement

My side is already signed

One person, one price, one date. The only signature still missing is yours, and you sign it only once the quote suits you.

Tell me what you need

Write a few sentences in your own words. I answer within one day with a fixed price, in writing. If you prefer email, that works just as well.

Optional. It helps me give you a fitting answer faster.
Describe your wish in normal words. That is all I need.

Not sure what to write?

You get a written answer within one day.

Half when we start, half when it goes live.
Fourteen days to pay. You are tied to nothing.
