Custom Software Development for Mid-Sized Companies

When standard products don't map your specialist processes and Excel is filling gaps that software should close — we develop the solution that truly fits your operations. Well-planned, transparently implemented, supported long-term.

When does custom software pay off?

Custom software means: not off the shelf, but developed specifically for your workflows. Companies with unique processes that no standard product covers cleanly inevitably end up with workarounds — manual transfers, Excel as the backbone, systems that don't talk to each other. Custom software replaces those compromises with a solution that truly fits your operations.

Choosing custom software is always an investment decision — not an end in itself. We help you assess whether and for which processes the effort really makes sense before we make a proposal.

When you should talk to us

  • Existing software doesn't map your specialist processes
  • Systems need to be connected and synchronised
  • Workflows are still managed via Excel or email
  • Legacy software needs to be modernised or extended
  • A customer, service or partner portal is needed

How we work

Requirements & concept

We don't write code until we truly understand your processes.

Requirements, roles, interfaces and your existing systems are carefully captured. Result: a clear concept, a transparent effort estimate and a fixed budget framework.

Development in phases

No surprises at the end — we deliver early and iterate with you.

We develop in manageable steps, show you the current status regularly and adjust priorities together. Early interim states are usable — you don't wait for a big final release.

Handover & long-term operation

The source code belongs to you — and we maintain it as long as you need.

After go-live we take care of hosting, monitoring, updates and further development. Transparent maintenance contracts, dedicated contacts, no lock-in.

Not an agency. A technical partner.

Many software projects fail not because of the technology — but because requirements stay at the surface, costs grow opaquely or nobody is reachable after acceptance. We work differently: with a clear concept before the first line of code, transparent budgets and long-term accountability.

What makes our projects safer

  • Concept and effort estimate before development
  • Fixed-price phases for reliable budgeting
  • Source code belongs exclusively to you
  • Documentation and handover as a contractual requirement

How we develop

  • Proven technologies — no dependency on a single vendor
  • Integratable with ERP, CRM, DMS and third-party systems
  • Extendable with AI automation
  • In mid-sized companies since 2007 — proven track record

Frequently asked questions about custom software

Custom software pays off when your specialist processes are too specific for standard solutions, manual workarounds arise, or existing systems need to be selectively extended. You invest once in a solution that permanently fits your workflows — instead of paying permanently for compromises.

Manageable specialist applications are completed within 3 to 6 months. Larger systems are planned in phases — so usable interim states arise early and you don't have to wait for a big final release.

We maintain your software long-term: hosting, monitoring, updates and further development. You have a dedicated contact who has known your solution from the start — no anonymous ticket system.

Yes. System integration is a core part of our work. We connect ERP, CRM, DMS, ticketing systems, databases and external APIs — the new software integrates seamlessly into your existing system landscape.

Yes. We develop software with AI-readiness in mind from the start — and can extend existing systems with AI capabilities later. Our combined expertise in software development and AI integration means we cover both from a single source.

You do. We transfer the complete source code to you as part of the project. You can have it maintained by us or by another provider — no vendor lock-in.
