System Integration for ERP, CRM, DMS and Business Processes

Data transfers by hand, information stuck in isolated systems, no connection between ERP, CRM and DMS — we eliminate these system breaks and connect your existing software into seamless digital process chains.

System breaks cost time and cause errors

Many mid-sized companies work with several specialised systems that have grown over years — often each chosen for good reason. The problem: they don't talk to each other. Data is transferred by hand, documents end up in the wrong places and errors arise in the transitions. System integration eliminates these breaks without requiring you to replace existing software.

Typical system breaks

  • ERP and CRM without connection
  • Documents not linked to records
  • Ticketing system isolated from other systems
  • Manual data transfers between applications
  • Separate data silos for the same business objects

What we connect

  • ERP systems (SAP, Microsoft Dynamics, etc.)
  • CRM systems (Salesforce, HubSpot, etc.)
  • Document management systems (DMS)
  • Helpdesk and ticketing systems
  • Industry-specific specialised software
  • External APIs and web services

How we integrate your systems

Analysis & architecture

We first capture your system landscape and identify the integration points.

Which systems need to exchange data? Which processes run across system boundaries? Which interfaces already exist? The result is a clear integration architecture with transparent effort estimates.

Development & connection

We develop interfaces, middleware and integration layers for your systems.

REST APIs, webhooks, file-based exchanges, database connections — we choose the right technology for each connection. GDPR-compliant, with role-based access controls and complete logging.

Operation & further development

We monitor your integrations and keep them running reliably.

System changes, API updates, new requirements — we react quickly and adapt integrations. Long-term responsibility from a single source.

Integration as the foundation for AI automation

System integration is not just about eliminating data silos — it is the prerequisite for AI automation. Only when your systems are connected can AI reliably process data, pass on results and trigger downstream processes. We therefore combine integration and AI automation from a single source.

Integration enables automation

  • AI reads data from ERP, CRM and DMS
  • Automated records are written directly to the target system
  • Processed documents are assigned to the correct process
  • Results trigger downstream workflows

Our combined services

Frequently asked questions about system integration

No. System integration means connecting existing systems, not replacing them. We develop interfaces and middleware that enable your systems to exchange data — without touching the existing systems themselves.

In principle, any system that provides an interface — REST API, SOAP, file-based exchange or database access. We have experience with SAP, Microsoft Dynamics, Salesforce, HubSpot, various DMS, ticketing systems and numerous industry-specific applications.

We implement all integrations with role-based access controls, encrypted data transfer and complete logging. GDPR compliance is part of the standard architecture, not an add-on.

We monitor the integrations and proactively adapt them to API changes. You are not on your own when systems update — we react quickly and ensure continuous operation.

Yes. System integration is the foundation for AI automation. Once your systems are connected, AI can reliably process data, pass on results and trigger downstream processes. We combine both from a single source.
