Integrations: your applications stay where they are

Integrations

Your applications stay
where they are

The most common worry in a first conversation is not the price, it is the migration. There is none. We do not replace software, we connect to it, as a rule read-only, and build around the routes that run by hand between applications today.

  • Property management

    casavi

    Portal, case handling and, since 2025, an AI phone assistant. What is still missing alongside it: matching at unit level, every channel in one basket, calculated deadlines.

  • Practices and offices

    DATEV

    Stays authoritative for master data and accounting. We read, through the file format, DATEVconnect or a gateway, and duplicate nothing.

    Microsoft 365

    Outlook, SharePoint and Teams are usually in place and paid for. We use them as what they are: the store the work already sits in.

    Take a look

These three are examples, not a list of what is possible. Among other things we have connected ERP systems, inspection software, maintenance archives kept as PDFs in folders, and an accounting package holding around 32,000 address rows. Where an interface exists, we use it. Where none does, we work from the files your application puts out anyway. Just ask about your own software.

Next step

Tell us what you run.
We will tell you what can be connected.

45 minutes, free of charge. We walk through one workflow and look at which of your applications are involved and how they can be reached. If it cannot be done sensibly, we say so before any quote exists.
