System integration for mid-sized businesses

Enter data once. Up to date everywhere.

System integration connects the systems you already use. We build integrations between your systems, business applications and automated workflows that fit the way you work. After go-live, we run and maintain them for you.

For mid-sized businesses with a few hundred to several thousand employees.

API integration, ERP integration and tailored business applications

Standard software covers a lot, but rarely everything. We build what your processes are missing and connect it to the systems you already use. Strategy, UI/UX design, development and operation come from one team.

Applications

Business applications

Software for processes that only exist in your organisation: applications for your staff, thoughtfully designed, easy to use and connected to your systems.

  • Strategy, UI/UX design and project management from one team
  • Browser-based applications, connected to your systems
  • Further development and maintenance after go-live

Apps for iOS and Android: Mobile apps

Integration

Integrations and automated workflows

We connect the systems you already use. Data is entered once and stays up to date everywhere, and recurring workflows run automatically to fixed rules.

  • API connection, file import and export, or database
  • Your staff keep working in the screens they know
  • ERP, online shop, specialist systems: enter data once
  • API development when a system has no interface yet

Industry experience: healthcare, retail, media and the public sector

We choose our industries deliberately and go deep. We know these requirements from our own projects.

  • Healthcare

    Electronic patient records for statutory health insurers

    We co-developed the electronic patient record (ePA), among others for Techniker Krankenkasse and Barmer, Germany's two largest health insurers. Health data under gematik specifications, FHIR, and strict data protection and security requirements were part of everyday work.

  • Retail and media

    Apps with many users

    For EDEKA we planned and built a shared platform for several apps, and for Mediengruppe RTL we developed apps including the wetter.de app.

  • Public sector

    Software for the public sector

    We have also built software for public authorities, among others on behalf of the City of Düsseldorf. We bring this experience to every new project.

Operation and maintenance of your integrations

After go-live we run and maintain your integrations for the long term: software maintenance by the team that built them, with services and contacts set out in a maintenance contract. Personal, customer and health data are protected by fixed rules.

  • 01

    Hosted in Germany or on your premises

    Cloud operation in a data centre in Germany, or on-premises on your own servers. We process data in line with the GDPR, and only as much as a workflow needs.

  • 02

    A complete log

    Every transfer is logged with time, source, target and result. The log stores IDs instead of personal data in plain text.

  • 03

    Monitoring with alerts

    Monitoring checks operation continuously. If something needs attention, we and your named contacts are notified at once.

  • 04

    Updates when an API changes

    When a connected system is updated, we adapt the integration. Your data keeps flowing as usual.

Frequently asked questions about system integration

More questions? Write to us.

Do we have to replace our existing systems?+
No. We connect and extend the systems you already have. Your staff keep working in the screens they know.
Standard software or custom software: which fits better?+
Standard software is available straight away; custom software fits your processes exactly. A mix often works best: you keep your standard software, and we add what your processes are missing.
Where is our data stored?+
In a data centre in Germany or on your own servers. You decide after the analysis workshop.
Do you look after the integration after go-live?+
Yes. We take over operation and maintenance: monitoring checks every transfer, we adapt the integration when a system is updated, and you have fixed contacts. The maintenance contract sets out what is included.
Which systems can you connect?+
Systems with an API, with file import and export, or with a database, for example ERP, online shop, HR and specialist systems. Whether and how a system can be connected is clarified in the analysis workshop.
How do we start, and what does it cost?+
It starts with an analysis workshop. Afterwards you know what we will build and what effort to expect.
