What is interface consulting?

Schiller & Partners helps companies connect their systems intelligently — CRM, ERP, accounting, project management. So data flows automatically instead of being transferred manually.

Data silos lead to duplicate work, errors, and poor decisions. A simple API connection can be set up in days, more complex integrations take 4–12 weeks.

Our Approach

How we create the foundation for your AI strategy together

Breaking Down Data Silos

We connect isolated systems through customized connectors and create a central, structured data layer – the essential foundation for any successful AI deployment, without replacing existing systems.

Connecting Legacy Systems

With special adapter technologies, we seamlessly integrate your proven legacy systems into modern AI-capable infrastructures – for maximum ROI of your future AI investments with minimal conversion costs.

Introducing Automation

We replace manual data entries with intelligent automation processes and APIs that ensure consistent, AI-suitable data quality and provide your team with valuable time for strategic tasks.

Typical Hurdles of Digital Transformation

Without structured, networked data, no meaningful AI deployment

Unstructured Data Silos

Valuable company data remains trapped in isolated systems and cannot be used for AI-based analyses and data-driven decisions.

Legacy System Isolation

Proven legacy systems cannot easily be connected with modern cloud services, AI platforms, and SaaS solutions, leaving valuable data unused.

Manual Data Transfer

Time-consuming and error-prone manual data entry leads to inconsistent data – an unusable foundation for any AI application and real-time analytics.

Our expertise helps you overcome these obstacles – whether for your own company or as a valuable addition to the digital solutions you offer your customers.
