01Approach

Technology that fits the way you work.

Every business runs differently. That is why we don’t start with a finished product, but with your processes, requirements and goals. From there, we build a solution that stays clear, reliable and easy to extend in day-to-day use.

  • Individually designed

    Features, interfaces and data models grow out of your workflows – not out of the limits of a construction kit.

  • Technically sound

    A clear architecture, clean interfaces and traceable decisions create a foundation that holds as requirements grow.

  • Supported long-term

    We stay on hand after launch – for operations, updates and the next stage of development.

Typical starting points – and what changes

  1. Data is entered several times: in the office, on site and again for invoicing.

    Information is captured once and passed on automatically.

  2. Systems only exchange data via exports, email or USB sticks.

    Interfaces ensure a validated, traceable flow of data.

  3. The standard software covers the essentials – everything else runs on spreadsheets and paper notes.

    Missing functions are added where needed instead of bending your processes.

  4. Teams in the field lack information the office has had for days.

    Jobs, history and documentation are available on the move.

  5. Legacy software is hard to change because structure and documentation are missing.

    A clear architecture makes step-by-step modernization possible.

02Services

From the first requirement to a running system.

Five service areas that can be commissioned individually – and that work together once separate tools become one integrated system.

All services at a glance

01Custom Software & App Development

Software that adapts to your business.

We build applications around your processes – from internal tools to complete industry-specific platforms.

Typical use case: workflows are spread across several tools, or employees on the move need the same information as the office.

  • Web applications
  • Mobile apps
  • Desktop software
  • Customer portals
  • Internal tools
  • Dashboards
  • Industry-specific applications
  • Offline-capable solutions
  • Role-based user areas

02IT Consulting & Technical Conception

Clarity first. Then development.

We translate operational requirements into a clear technical structure – a solid basis for development, budget and scheduling.

The result is a decision basis with clear priorities – useful even if you implement parts in-house or with other partners.

  • Analysis of existing processes
  • Technical architecture
  • Feasibility assessment
  • Technology selection
  • Requirements definition
  • Project planning
  • Modernization strategy
  • Technical documentation

Capture requirements

Workflows, stakeholders, existing systems and constraints are documented together.

ResultPrioritized list of requirements

Requirements → Architecture → Prototype → Implementation → Operations: every phase ends with a tangible result.

03Interface Development & Architecture

Systems that talk to each other.

We connect existing applications and create a reliable flow of data – without duplicate data entry, unnecessary exports or error-prone manual handovers.

Example: data exchange between several parties

A contractor records job and documentation data, an engineering firm reviews it, and the client needs documentation that can be traced. An interface turns this into structured files, for example in XML format, checks them for completeness and format before sending, transfers them to all parties and processes their responses – without anyone retyping data.

  • XML interfaces
  • REST APIs
  • GraphQL
  • Data imports
  • Data exports
  • ERP integration
  • CRM integration
  • Accounting systems
  • Synchronization
  • Data validation
  • Technical documentation
  • Automated handovers

04Workflow Digitalization

Digital workflows that work in everyday operations.

We build digital tools for real working days – easy to use in the office, reliable in the field and free of unnecessary duplicate work.

What matters: large controls, few steps and a solution that keeps working on a weak connection.

  • Digital job workflows
  • Mobile data capture
  • Scheduling
  • Documentation
  • Photo documentation
  • Digital forms
  • Customer portals
  • Signatures
  • Automatic handovers
  • Reports
  • Office and field

05Hosting: Domains, Email & Websites

Development and operations from a single source.

Beyond development, we can also take care of your domain, email, hosting, security, backups and reliable day-to-day operations.

You have one contact for application and infrastructure – no need to work out who is responsible when something goes wrong.

  • Domain registration
  • DNS configuration
  • Professional email addresses
  • Websites
  • Web hosting
  • SSL certificates
  • Backups
  • Monitoring
  • Technical maintenance
  • Updates
  • Post-launch support

03Projects

Custom software. Real challenges. Tailored solutions.

From digitalizing internal business processes to developing specialized applications for different industries: we design and build software that is shaped by our clients’ actual requirements.

All projects in detail

For reasons of confidentiality, we publish our project examples without naming the respective clients.

04Industries

Where custom solutions make the difference.

We work across a range of industries. What matters is not the industry, but that processes have specific requirements and data moves between several parties. Select an industry to see a typical example.

Example

A job is created in the office, completed on site, documented with photos and then handed over in a structured format to the client and to billing.

  1. Office
  2. Mobile
  3. Documentation
  4. Handover

Related services: Workflow digitalization, Software & apps

Example

Data from several contractors arrives in varying quality. An import pipeline validates and standardizes it and flags inconsistencies before the technical assessment begins.

  1. Intake
  2. Validation
  3. Standardization
  4. Assessment

Related services: Interfaces, IT consulting

Example

Information is scattered across ERP, spreadsheets and inboxes. An internal tool brings it together in one interface with clear roles, approvals and current data from connected systems.

  1. Data sources
  2. Consolidation
  3. Roles
  4. Approval

Related services: Software & apps, Interfaces

Example

An idea for a new digital service first becomes a prototype that is tested with real users. Only then does the platform grow step by step.

  2. Prototype
  3. Testing
  4. Platform

06Principles

What you can hold us to.

  • Custom-built, not off the shelf

    The solution is shaped by your requirements, not by a predefined construction kit.

  • Technical decisions you can follow

    We explain architecture, options and limitations so that every decision remains transparent.

  • Clean, maintainable development

    Software should not only work today – it should still be easy to extend and operate tomorrow.

  • Collaboration on equal terms

    Short lines of communication, clear agreements and visible progress keep everything transparent.
