Prices: open, fixed, without a timesheet#
No hourly billing. The price is fixed before we start — in the written scope sheet, with acceptance criteria. What that means for you: you budget beforehand, not afterwards.

What every price includes#
Clickable prototype (€1,200): discovery call, wireframes (≤ 12 screens), clickable prototype, recorded walkthrough, one revision round, written recommendation. Not included: software, backend, real data.
Prototype sprint (€4,800): scope sheet with exclusion list, Flutter app or Jaspr web application, Serverpod backend with schema and API docs, authentication with roles, deployment with TLS/backups/monitoring, repository, README, dev docs, CI, handover workshop (2 h), 30 days of bug fixing, one design feedback round per screen. Not included: anything not on the scope sheet, store submissions, support beyond 30 days, third-party licences, production guarantee.
Sprint Plus (€9,600): the same method across eight weeks — two workflows, one admin role, one data migration, one release. The advantage over two sprints: one scoping, one architecture, one handover.
Production development (fixed price per scope): a production application out of the sprint or directly from a scoping workshop. Fixed price from a written scope, weekly delivery, written acceptance, handover.
Build-out (€480/day): blocks of 5–10 days after a sprint, agreed change backlog, monthly summary. Only after a sprint — without one it would be unpaid specification work.
AI module (€1,200–2,400): one concrete process, data-flow documentation, fallback path, accuracy statement, AI Act note.
What changes the price#
Only the written change order: if you want to change something during the project, the order states what changes, what it costs and what moves. There are no discounts — the only exceptions are a smaller scope at list price and a documented entry price of at most −10%, once per client.
Payment plan for the sprint#
| Milestone | Share |
|---|---|
| Kickoff (order placed) | 40% |
| Live demo in week 3 | 40% |
| Handover/acceptance | 20% |
Payment terms 14 days, then default interest under § 288 BGB. On early termination the delivered work is invoiced (at least 40%); delays caused by you move dates in writing.
Maintenance & operations#
After a sprint, I can take over operation and maintenance on request:
- hosting and TLS renewal
- dependency and security updates
- monitoring and backup verification
- up to 4 hours of small changes per month
- a written monthly status
€240/month, cancellable monthly. Larger changes run through the build-out or a new fixed price. No obligation: many clients run their software with their own IT — the code is yours, and the documentation is written for exactly that.
Comparison with the market#
A Munich agency typically quotes a considerably higher budget and four to six months of planning for the same functionality. The reason for my price is not a discount but structure: one developer instead of a team, fixed scope instead of an open end, an established stack instead of experiments.
For context: MVP specialists on the market quote €10,000–30,000 fixed for comparable work. The prototype sprint sits below that at €4,800 because it concentrates on one core process and the handover moment is fixed at four weeks.
To be honest#
The sprint is not a subscription and not the entry into a support relationship you can't leave. After the handover you decide in your own time: build-out, maintenance, your own operation — or done. The first call is free and ends with an honest yes or no.
