System Integration – references from ERP, CRM and interfaces
Here you'll find selected case studies on system integration: from API orchestration and multi-system platforms to interface development – built in East Frisia, Made in Germany.
What we integrate
Connect systems, keep data consistent
Grown IT landscapes consist of many isolated solutions. We connect ERP, CRM and shop via interfaces so that master data, documents and stock stay consistent without double entry.
ERP, CRM & shop connectivity
Connect existing systems so documents, master data and stock levels stay consistent without double entry.
To the serviceAPI & interface development
REST, webhook and batch interfaces with stable handovers, error handling and monitoring.
To the serviceProcess & data-flow automation
Automate data flows between channels and departments — with queues, rules and traceable logs.

Eight case studies from integration practice
From interface development and connecting automation workflows to integrating legacy systems — these projects show how systems work together reliably.
API orchestration for e-commerce & ERP
Central orchestration of interfaces between shop, ERP and logistics — orders, stock and status run through a reliable, monitored data flow.

Book a consultationWhy clean system integration decides project success
Short answer for decision-makers: When systems don't work together cleanly, you get double entry, duplicates and outdated stock. Our references show how ERP, CRM, shop and legacy systems can be connected via stable interfaces — developed in East Frisia, Made in Germany.
Typical starting points
We frequently see the same patterns: orders transferred manually between shop and ERP; leads from various channels without a unified CRM; or legacy systems that hold valuable data but lack a modern interface.
The consequences are more than extra work: rising error rates, duplicate records and latency until stock or status is current. A continuous data flow with clear handovers addresses exactly these media breaks.
Our approach
We separate connection, validation, handover and operations into traceable steps. Where APIs exist, we rely on clean interfaces; where they don't, we add RPA — see the RPA vs. API integration comparison.

Knowledge & answers
Frequently asked questions about system integration references
Approach & cost-effectiveness
What do these integration references say about how you work?
When is real integration worth more than manual export/import?
As soon as the same data is maintained in several systems, duplicates or media breaks occur, or processes rely on up-to-date stock and master data, real integration pays off. We often start with a clearly scoped data flow, measure error rate and effort, and only then expand — keeping the budget controllable.
How do I weigh API integration against RPA?
Technology & operations
Which systems do you typically connect?
We work vendor-neutrally via REST APIs, webhooks, batch files and — where needed — RPA. In the references we connected ERP, CRM and shop systems as well as Lexware, Clockify and Timebutler. Specific vendors are clarified under NDA; the goal is always a stable interface that respects your existing landscape.
How do you handle errors, retries and monitoring?
Integration needs operational logic: queues, retries for temporary failures, notifications to owners and dashboards or logs for IT operations. This lets you see whether records get stuck before the business notices — a core point of all reference descriptions.
