Knowledge & Answers

Common Questions About Our Services

Collaboration & Getting Started

How do we best get started – even without a finished specification?

We usually start with a short discovery workshop (goals, users, processes, risks) and define a clear approach with priorities, effort, and next steps. No specification needed – we work together to determine what's really needed.

Which service is right for my project?

For new products or custom applications: Software Development. For existing system landscapes: Integration/Interfaces. For data quality or reporting issues: Database Solutions and Analytics. Unsure? We'll quickly clarify that in an initial consultation.

Do you also work with existing teams?

Yes, we often act as a co-creation partner: pairing with your developers, code reviews, architecture consulting, and enablement. Or we take over complete sub-projects while your team handles other areas.

Unsure what you need?

In 30 minutes, we clarify scope, priorities, and next steps.

Project Process & Results

How quickly will we see first results?

Often within a few weeks: quick wins in performance, stability, or integrations. Larger projects deliver iteratively – not just at the end. You see regular progress and can give early feedback.

How does the collaboration actually work?

Transparent and pragmatic: clear goals, measurable KPIs, regular check-ins (usually weekly or bi-weekly). Clean definition of done incl. tests, security, and operations documentation. You always have insight into progress.

Can you also support ongoing operations?

Yes, we take over stabilization, maintenance, and further development of existing systems. Also third-party code after audit. Many clients we've supported for over 10 years – long-term partnerships are our model.

Costs & Budget

How much does a service typically cost?

Depends on scope and complexity. Workshops from €3,000, MVPs from €20,000, complex projects €50,000-200,000+. After the initial meeting, you'll receive a transparent effort estimate with clear milestones.

Fixed price or time & materials?

Both possible. Fixed price for clearly defined scope. Time & Materials for agile projects with evolving requirements. Hybrid models (fixed price for base features, T&M for extensions) are often ideal.

Budget planning for your project?

Technology & Quality

What technologies do you use?

The right one for the use case: React/Next.js, Laravel, .NET, Delphi, Flutter, Python, Node.js, and many more. We're not dogmatic – we choose technology based on requirements, not hype.

How do you ensure quality?

Code reviews, automated tests (unit, integration, E2E), CI/CD pipelines, security checks, and documentation. Quality is part of every sprint, not an afterthought.

Do you only develop in Germany?

Yes, exclusively. Our team is based in Leer (East Frisia). No offshoring, no timezone issues. This guarantees data protection, short communication paths, and the highest quality standards.

Why Custom Software?

Off-the-shelf software covers many use cases – but as soon as your processes, industry, or scaling needs differ from the norm, a one-size-fits-all solution hits its limits. Custom software is built exactly for your requirements: you pay only for the features you need, and the architecture grows with your business. No overpriced licence bundles for unused modules, no rigid workflows that your staff have to work around, and no dependence on a vendor who sets roadmap and pricing unilaterally.

On this page you will find our services organised by topic: from mobile and web development to AI integration and knowledge bases, ERP systems, APIs, and legacy modernization. Each service is delivered by experienced developers and architects based in Germany, supporting you from the first idea to production. We focus on clean technology, documented interfaces, and a handover process that ensures you are not dependent on us in the end – although many clients retain us long-term for maintenance and extensions.

Whether you need a single service such as an app or an AI knowledge base, or are planning a broader digitalization project with several building blocks: we will advise you without obligation and show which steps make sense, in what order, and with what effort. Use the links below to dive into the details of each service, or schedule a free initial call to outline your project.
