Services · fixed prices
Four ways to work with us, each at a fixed price.
We keep each project deliberately small, so we can keep the price fixed. Before anything starts, you know the price, the timeline, and exactly what you’re getting.

How the steps fit together
You can start at any step, and stop after any of them.
- Step 1
Diagnose
We review what you have right now and rank every finding by risk, so you know what to fix first.
- Step 2
Prove
We build and test the flow you're least sure about, before you commit to the full build.
- Step 3
Build
The same team designs and builds the product, at a fixed price for the scope we agree on.
- Step 4
Keep
We stay on after launch, so new features get the same checks as the first release.
Scope and payment
We fix the scope before any work starts.
How do you keep the price fixed?
We keep each project deliberately small: one flow, one file, or one set of journeys. We fix the scope before work starts. If you need more, we scope the extra work separately, so the original price and timeline don't change.
How do payments work?
Projects under €5,000 are paid in full before work starts. For projects at €5,000 and above, you pay 50% at kickoff and 50% on delivery. Once we've agreed on the scope, the price is fixed.
Do we have to have calls every week?
No. We work asynchronously in the files and repository you already use, with agreed review points and a written update every week. If you want a call, you can always book one.
Can we sign an NDA first?
Yes. If you need one before sharing files, send it with your first email.
What if our project doesn't fit any of these?
Tell us what you need. If it doesn't fit one of these, we'll say so, or we'll scope it separately.
