Development & Engineering

Custom apps, extensions and interfaces — clean AL code to Microsoft standards. Engineering from Germany for SaaS and on-premises, from the small tweak to the AppSource app.

Where the standard ends, our work begins. We build extensions that are upgrade-safe and feel like they were always part of Business Central — no hacks that break with the next release. And if you're still on classic NAV: we know C/AL just as well.

What we deliver

Custom extensions (AL)

Tailored functionality as clean extensions — upgrade-safe, tested, documented.

AppSource apps

We build and publish market-ready apps including AppSource validation and test toolkit.

Interfaces & integration

EDI, e-invoicing (XRechnung/ZUGFeRD), DATEV, Graph API, FTP/REST — we connect Business Central to your landscape.

Reports & documents

RDLC and Word layouts that not only calculate correctly but also look and print well.

AI integrations

Useful AI right in the document flow — classification, suggestions, automation instead of gimmicks.

Legacy & modernisation

C/AL work on existing NAV installations and the path toward AL/cloud.

Typical engagements

Feature development

A clearly scoped extension with requirement, build, test and acceptance.

Interface project

Connecting suppliers, authorities or third-party systems (EDI, e-invoicing, DATEV).

Report package

A document set designed in your CI — from order confirmation to invoice.

App hardening

Making an existing extension upgrade-safe and AppSource-compliant.

A good fit if …

  • The standard does 90 % and the missing 10 % hurts.
  • You need an interface that runs truly reliably.
  • You want to publish your own idea as an AppSource app.
  • You're stuck on NAV and want a clean modernisation.
