Interfaces that constantly cause problems?
We bring order to the chaos.
Sometimes data is missing, sometimes inventory is wrong, sometimes jobs run twice – interfaces cause problems. We bring order and systematically resolve the typical root causes.

Typical Symptoms
Does this sound familiar?
Spaghetti Connections
Point-to-point without standards or documentation
Errors Without Cause
Data is missing or wrong – nobody knows why
Partner Onboarding Takes Ages
New integrations take weeks instead of days
Manual Workarounds
Excel exports and manual corrections in daily operations
No Visibility
Problems only noticed when customers complain
Sporadic Outages
Jobs run twice, queues overflow

How We Stabilize Your Interfaces
| Your Problem | Our Approach | Your Result |
|---|---|---|
| Unclear data formats | API contracts (OpenAPI/AsyncAPI) | Clear contracts, fewer errors |
| Problems detected too late | Observability + alerting | Proactive detection before customer impact |
| Data gets lost | Retry strategies + dead-letter queues | Robust processing without data loss |
| Long onboarding times | Self-service APIs + documentation | Partner integration in days |
| Security concerns | IAM, secrets handling, rate limits | Secure and controlled access |
Proven Methods
Best Practices That Work Immediately
API Contract & Versioning
OpenAPI/AsyncAPI, breaking change rules, deprecation policy. This keeps changes manageable.
Observability
Tracing, SLIs/SLOs, alerting, and dashboards. Problems become visible before customers notice.
Robust Processing
Idempotency, retry policies, dead-letter queues. Minor issues no longer lead to data loss.
Security by Design
IAM, secrets handling, rate limits, and audit logs. Secure yet user-friendly.

Frequently Asked Questions
FAQ on Interfaces & Integration
REST or eventing – which is better?
Both – depending on the use case. REST is good for queries and control, events for decoupling and real-time updates. We design both consistently with contracts and monitoring.
Do we need middleware/iPaaS?
When multiple systems and partners are involved, a platform often makes sense. What matters isn't the tool, but standards, ownership, and tests.
How quickly will we see improvements?
Usually fast: observability, contract tests, and robust retry strategies often reduce incidents significantly within a few weeks.
What does an integration analysis cost?
An initial integration landscape map with prioritization starts at approx. €3,000. Implementation depends on scope – always with clear milestones.

Book ConsultationStabilizing Interfaces: From Point-to-Point to Strategic Integration
Interfaces are the invisible nervous system of a company. They connect ERP with shop, CRM with email system, warehouse management with shipping provider, and accounting with payment provider. When these connections work reliably, nobody notices. When they fail, the entire company feels it: orders get lost, inventory doesn't match, invoices are sent twice, and customer service spends hours searching for root causes.
The fundamental problem in most companies has grown historically. Every new application, every new partner, and every new tool was connected via point-to-point integration – often under time pressure and without overarching architecture. The result is a web of dozens or hundreds of individual connections using different protocols, exchanging different data formats, and understood by nobody as a whole. Finding errors in this network is like searching for a needle in a haystack.
Our approach to stabilizing interfaces begins with transparency. In the first step, we create a complete integration landscape map: which systems communicate with each other? Via which protocols and formats? How frequently? What happens when errors occur? This inventory alone often yields valuable insights because it reveals dependencies that were previously only implicitly known.
Based on this analysis, we define an integration strategy that fits your system landscape and growth plans. We rely on proven architectural principles: API-first design with clear contracts (contract testing), event-driven architecture for loose coupling and real-time updates, centralized monitoring with alerting for proactive error detection, and standardized error handling with retry mechanisms and dead-letter queues. These building blocks systematically reduce complexity and make your integration landscape manageable.
Particularly important is the introduction of contract testing. A formal contract is defined for each interface, specifying which data in which format is expected. Changes to an interface are automatically checked against this contract before going to production. This prevents the most common source of errors: unannounced changes on one side of an integration that cause outages on the other side.
Another focus of our work is the introduction of observability. We implement structured logging, distributed tracing, and metrics for all critical data flows. This lets you see in real-time which integrations are running, where errors occur, and how latencies develop. Problems are detected before customers notice them, and troubleshooting is reduced from hours to minutes.
The results speak for themselves: our clients typically report a reduction of integration-related incidents by 70 to 90 percent within the first months. At the same time, the time for onboarding new partners or systems drops drastically because standardized interfaces and clear documentation accelerate integration. What used to take weeks can be done in days with the right architecture.
