Software development

Software that fits the way your operation actually works.

We build new applications, rebuild the ones that no longer keep up, and migrate the ones that have to move — for finance, operations, manufacturing, and service teams. Always integrated with the systems you already run.

Three ways we take on software

New build, rebuild, or migration — each with its own rules.

The wrong approach is expensive in both directions: rebuilding what only needed a migration, or patching what really needed a rebuild. We say which one fits before we quote.

01

New build

When no standard product fits the process, or the process is your competitive edge.

What we do

  • Discovery with the people who will use it
  • Clickable prototype before real build
  • Backend, API, web and mobile front-ends
  • Integrations designed in from day one

What you get

  • A working first version in production early
  • Documentation and a maintainable codebase
  • A team that knows the process, not just the code
02

Rebuild & modernization

When an application still does the job, but nobody dares to change it anymore.

What we do

  • Map what the current system really does
  • Refactor, re-platform, or replace per module
  • New UI on a stable backend where that is enough
  • Parallel running and staged cut-over

What you get

  • Business continuity during the change
  • Clear rollback paths at every step
  • A platform you can keep improving
03

Migration

When data, workflows, or an interface have to move to another system or platform.

What we do

  • Data mapping, cleansing, and validation rules
  • Migration scripts with dry runs and reconciliation
  • Interface migration (file → API, on-prem → cloud)
  • Cut-over plan with go / no-go criteria

What you get

  • Reconciled data you can trust
  • A cut-over that was rehearsed, not improvised
  • Old and new running side by side until proven

Application domains

Applications for finance, operations, manufacturing, and service.

Most of what we build is a dashboard, an internal platform, or a workflow application that sits between people and the core systems — the place where the daily work actually happens.

Dashboards & reporting
Operational and management views on live data
Internal platforms
Planning, portfolio, request, and approval tools
Operator & mobile apps
Shop floor, field service, inspections, offline-capable
Portals & self-service

  • 01

    Finance

    • Approval and exception workflows
    • OCR + AI document intake
    • Savings and portfolio dashboards
  • 02

    Operations

    • Resource and machine planning
    • Request routing and follow-up
    • Product and fabrication finders
  • 03

    Manufacturing

    • MES-style execution support
    • Machine-connected operator apps
    • Traceability and batch records
  • 04

    Service

    • Installed-base monitoring
    • Inspection and maintenance flows
    • Assistant-style AI guidance

Integrations

Built to exchange data with SAP, Dynamics 365, ERP, CRM, and your APIs.

An application that does not talk to the core systems creates rekeying. We design the integration layer first: which system owns which data, how changes flow, and how failures are made visible.

  1. 01

    API integration

    REST / OData, authenticated, versioned, monitored

  2. 02

    Event & message based

    Queues and webhooks for near-real-time updates

  3. 03

    SAP IDoc / BAPI

    Documents and postings into ECC and S/4HANA

  4. 04

    Dynamics 365 Dataverse

    Finance, Supply Chain, Sales entities

  5. 05

    File & batch exchange

    Where it is still the pragmatic option — with reconciliation
