30 minutes · free · you talk to the architect who builds

TYPICAL STARTING POINTS

Three situations mid-sized companies bring to us.

request_quote

A proposal for 60,000 € and six months is on the table – for a problem that fits on one page.

We read it with you and tell you the scope and the price the problem actually needs.

design_services

The new software is meant to be used every day in the warehouse and in the field.

We build along your process: the people who will use the software see running increments before it is delivered.

account_tree

The development team is good, and the architecture needs an owner.

An architecture review gives the team the decisions it can orient itself by – documented and prioritised.

Our job in the first call: after 30 minutes you can place the technical proposal on your desk – with a clear assessment of scope and price.

WHAT YOU CAN HIRE US FOR

Two services. One architect. Direct contact.

FIXED PRICE 9,500 €

MVP Sprint: your software in eight weeks

Web frontend, Android app, backend and database – designed by a senior architect, delivered as a running system in your environment. Scope fixed in writing, hand-over documented.

PROJECT-BASED OR DAY RATE

Architecture advisory: review, roadmap, second opinion

An independent review of your architecture, a plan for replacing legacy systems, or an honest assessment of the proposal sitting on your desk right now.

HOW IT WORKS

From the first call to a running system.

  1. 01

    30-minute architecture call

    You describe the bottleneck. We tell you what of it fits into the sprint – and what follows as a build-out afterwards.

  2. 02

    Scope in writing, price fixed

    What gets built is on paper before you pay anything. Everything beyond it is quoted separately – also in writing.

  3. 03

    Eight weeks of engineering

    Architecture and data model in weeks 1 and 2, development in weeks 3 to 6, delivery and validation in weeks 7 and 8. Running increments in every phase.

  4. 04

    Then you decide

    Trial with real users, then milestone-based build-out, monthly development – or hand-over to your own team.

WHY YOU CAN BELIEVE US

We operate what we build.

We show you software we run in production ourselves – with every consequence that brings. Every statement here you can check yourself.

What the MVP Sprint is built for

  • You have a concrete operational bottleneck: order intake, field documentation, customer-specific catalogues, hand-off into the ERP.
  • You have a proposal on the table and want an independent assessment of whether it is fair.
  • You have developers and want to put the architecture into responsible hands.
  • You want a system at the end that your own team or another provider can continue – documented, on a widely used stack.
  • You want scope and price fixed in writing before the start.

Whatever goes beyond the sprint we offer separately – in writing, before we start.

Frequently asked questions about custom software from Cloudwerks

What does custom software cost at Cloudwerks?

The MVP Sprint costs a fixed 9,500 € for web frontend, Android app, backend, database and deployment in eight weeks. The price is agreed in writing before work starts and covers the entire agreed scope. Architecture advisory is offered project-based or at a day rate. For reference (market ranges, as of 2026): agencies in the DACH region charge 25,000 to 75,000 € for comparable scope over three to six months; a senior freelancer charges 800 to 1,200 € per day, i.e. 32,000 to 48,000 € for eight weeks.

Are eight weeks realistic for a running system?

Yes, for an MVP scope bounded in writing. Authentication, synchronisation, catalogue management and ERP hand-off exist as proven modules from our own products. We build what is different about your case. Whatever goes beyond the sprint we plan as a build-out in the first call – in writing, before the invoice.

How is the source code handled?

Usage and ownership rights to the source code are agreed in the contract, matched to your project – we discuss this in the architecture call. Regardless of that, the code is always fully documented and built on a conventional stack (Angular, Kotlin, Spring Boot, SQL, Android) that any competent development team can continue.

What happens after the eight weeks?

First a trial phase with real users in your operation. Then either milestone-based build-out, monthly development on a retainer – or hand-over to your own team. You decide how to continue after the trial, not before.

How does Cloudwerks, as a small company, ensure continuity?

Through documented architecture, a widely used stack and code any competent team can take over. We build for hand-over from day one. In addition, the person in the first call is the person who designs and builds – decisions and knowledge sit in one place and are written down.

Does Cloudwerks work across Germany?

Yes. Cloudwerks is based in Gelsenkirchen and works across Germany; enquiries from Austria, Switzerland and the Netherlands are equally welcome, in German or English. Architecture calls take place via video; on-site meetings in the Ruhr area and North Rhine-Westphalia are possible at short notice.
