Custom software, integrations and moves to Azure, built on .NET

Inthouse builds custom apps and integrations on .NET and Azure for organizations that off-the-shelf products don't serve, and moves applications to Azure in planned steps. We've built custom software for TRUMPF, Nestlé, Howden and Mercedes-Benz Türk.

Does this sound familiar?

  • Off-the-shelf products and packaged software don't quite fit the way you work.

  • People copy data by hand between your CRM, ERP and Microsoft 365.

  • You want to move your on-premises applications to Azure but aren't sure where to start.

  • You need a custom app for a job that Microsoft 365's standard features can't handle.

What we do

  • Custom apps

    We build apps and services on .NET for work that off-the-shelf products don't cover. With Microsoft Entra ID, these apps can let people sign in with their existing Microsoft 365 accounts.

  • Integrations

    We build and run integration software that connects systems such as your CRM, ERP and Microsoft 365. Microsoft Graph gives programmatic access to Microsoft 365 data.

  • Apps for Microsoft 365

    We build apps that work with Microsoft 365 accounts and services, such as sending bulk email through company accounts. We also build our own Microsoft 365 products, including Admin Toolkit and Mailtiv, and offer them on Microsoft Marketplace.

  • Planned moves to Azure

    We assess your applications and data first, then move them to Azure step by step. Some apps move as they are, others are adapted or rebuilt.

How do you move an application to Azure?

Not every application takes the same route. Some move to Azure as they are, some are adapted for the cloud, and some are better rebuilt. That's why a move starts with a review of each application and its dependencies.

  1. Discover

    We review your applications, data and connected systems against your goal.

  2. Design

    We pin down the route for each app, the Azure architecture and the timeline.

  3. Deliver

    We carry out the move and any development it needs, step by step.

  4. Support

    After go-live, SLA-backed support keeps things running.

Frequently asked questions

Which technologies do you build with?

Mostly .NET and Azure. We also build apps that work with Microsoft 365, SharePoint and Dynamics.

Can you move one of our existing applications to Azure?

Yes. We review the application and its dependencies first. Then we decide with you whether to move it as is, adapt it or rebuild it.

Custom software or an off-the-shelf product?

It depends on the job. If Microsoft 365, Power Platform or an existing product does the work, we'll recommend that first; if not, custom software makes more sense.

Our data must stay on-premises. Is Azure still an option?

Yes, not everything has to move to the cloud. The application can stay on-premises while Azure handles integrations or new services. We decide together during discovery which data lives where.

Do you support the software after go-live?

Yes. After go-live, SLA-backed support keeps things running. Keeping the software we build up and running is part of that support.
