Interfaces that constantly cause problems?
We bring order to the chaos.

Interfaces that constantly cause problems are the invisible nervous system of a company gone wrong. 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.
