System integration & interfaces · Consulting

System integration that holds.

We connect ERP, CRM, shop and bespoke systems so that data flows reliably between them — through modern APIs, events and established standards. Cleanly built, fully observable and introduced during live operation, not in a risky big-bang switch.

Why it matters

Isolated systems quietly cost you money.

Most companies do not run a single application — they run a landscape that has grown over years. Where those systems do not talk to each other, the gaps are filled by hand.

An order arrives in the shop, is re-keyed into the ERP, copied into the warehouse system and reconciled against accounting at month-end. Every manual hop introduces delay, transcription errors and a dependence on individual people. Master data drifts apart, customers receive contradictory information, and reporting rests on figures nobody fully trusts. As the business grows, this friction grows with it — until a launch, a migration or an audit makes the cracks impossible to ignore.

Sound integration removes that friction at the source. When systems exchange data automatically, reliably and traceably, your people stop being a copy-and-paste layer between applications and your figures finally agree. That is the difference between an IT landscape that slows the business down and one that quietly carries it.

What we do

Interfaces, end to end — built to last.

We do not bolt on a quick connector and walk away. We design the data flow, build it cleanly, monitor it and hand it over documented.

— 01 / Connectivity

APIs & interface development

We build and consume interfaces across system and vendor boundaries — robust, versioned and secured. Where no API exists, we create one rather than papering over the gap.

  • REST & GraphQL APIs
  • SAP via IDOC, BAPI & RFC
  • EDI, IDOC & AS2 standards
— 02 / Architecture

Enterprise application integration

We connect ERP, CRM, shop and bespoke systems into one coherent landscape — with clear responsibilities, message and event flows, and a single version of the truth for shared data.

  • Event- & message-driven flows
  • Master-data & process integration
  • Synchronous & batch interfaces
— 03 / Reliability

Monitoring & operability

An interface is only as good as your ability to trust it. We make every flow observable, recoverable and documented, so your team can operate and extend it with confidence.

  • Monitoring & alerting
  • Idempotency, retry & replay
  • Documentation & handover

How we work

A measured path to a landscape that talks.

No big-bang risk. We move in clear stages, prove each one against real data, and switch over only when it is safe.

— Step 1

Understand the landscape

We map your systems, data and processes, find the painful manual hops and agree where integration creates the most value first. You get a clear picture before a single line is written.

— Step 2

Design the data flow

We define interfaces, formats, error handling and the real-time-versus-batch split deliberately — driven by the business case, with operability and future change designed in from the start.

— Step 3

Build & run in parallel

We implement incrementally and run the new interfaces alongside the existing setup, validating against live data. Nothing is switched off until the replacement has proven itself.

— Step 4

Hand over & support

You receive monitoring, documentation and a clean handover. We stay available for evolution and support — but you are never locked into us to keep the lights on.

Track record

Two decades of mission-critical interfaces.

Integration is our home discipline. Our roots reach back to classic enterprise integration (including BizTalk), and we have owned interface platforms in landscapes that simply cannot stop — for clients whose names you know.

Whoever has kept interfaces, data flows and stability running at that level for years can build the modern with confidence: clean APIs, event-driven flows, containerised .NET services and data platforms that hold under load. We bring senior attention to every project — no junior ballast, no hand-off to a team you never met.

Frequently asked

Good to know.

Which systems do you connect?
Practically every business-relevant system: ERP platforms such as SAP and Dynamics 365, CRM systems, online shops and marketplaces, warehouse and logistics software, document and payment platforms, as well as grown bespoke applications. We connect them through modern REST and GraphQL APIs, message and event streams, and established standards such as EDI, IDOC and AS2 — so data flows reliably between them rather than being keyed in twice.
Can you integrate SAP?
Yes. SAP connectivity is a core discipline for us. We work with IDOC and BAPI interfaces, RFC, OData services and file-based exchange, and we wrap them in clean, monitored interfaces towards the rest of your landscape — including S/4HANA. The aim is a stable, documented connection that your team can operate and extend without depending on us.
Real-time or batch?
Both — and the choice is driven by the business case, not by fashion. Order confirmations or stock figures that users see immediately call for event-driven, near-real-time interfaces; large reconciliations, invoicing runs or nightly master-data syncs are often better and cheaper as scheduled batch jobs. We frequently combine the two in a single landscape and make each interface observable so you always know what ran and what is pending.
Can this run during live operation?
Yes. Most of our integration work happens in landscapes that must not stop. We introduce new interfaces incrementally, run them in parallel with the existing setup, validate against real data and switch over only once everything is proven. Idempotent processing, replay and clear monitoring mean a single failed message never brings the whole exchange down.
