Professional Services Integrates Legacy ERP with AI Layer, Eliminates Data Silos

A London professional services firm integrated legacy ERP systems with custom AI automation layer, eliminating data silos and reducing technical debt.

The Challenge

The IT team in London manages 5 disconnected systems. Data lives in silos: SAP for finance, Salesforce for CRM, custom tools for project management. Each system requires separate maintenance—35 hours per week spent on integration patches, data reconciliation, and manual exports. Technical debt accumulates: €180K in integration costs, vendor lock-in risks, system complexity growing. The IT Director tracks the burden: 5 data silos, high integration complexity, €180K technical debt, 35 hours/week maintenance. System ownership is eroding.

How We Rebuild the Logic

Efficiency is not an accident; it is engineered. We do not patch your current workflow. We rebuild the logic that drives it.

01

Diagnose

CHF 10,000 forensic analysis: Map every system touchpoint, quantify integration complexity, identify modernization opportunities. We audit your current architecture—no assumptions.

02

Architect

Custom AI layer: Legacy ERP integration (REST APIs), data unification layer (ETL), automation orchestration (Python). We rebuild the logic that connects systems—not patch your current architecture.

03

Transfer

You own the system—not rent. Full code transfer, documentation, training. Technical debt eliminated: 8 months. System ownership restored.
