Which ERP System Integrations Matter Today?

Why this matters

IBM positions iPaaS as the current gold standard for ERP integration, replacing point-to-point connections. NetSuite reports that Mittelstand ERPs typically connect to thirty or more applications via middleware. Without clean integration, data silos emerge and block every modernisation attempt.

A real-world example

A consumer goods manufacturer with 320 employees in Switzerland replaced fourteen nightly batch jobs with APIs and an iPaaS layer. Data freshness improved from twelve hours to ninety seconds, manual reconciliations almost disappeared.

The main integration patterns compared

Thinking from first principles, choose the integration pattern by data freshness and business impact: real-time needs go to APIs, bulk data to file or ETL, complex landscapes to iPaaS or ESB.

• REST API: real-time, structured, modular. Standard for cloud ERP and modern web applications.
• File interface (CSV, XML): simple to implement, ideal for bulk data and nightly transfers.
• iPaaS: central layer for routing, transformation and monitoring of complex landscapes.
• ESB or middleware: classic option for many heterogeneous systems in on-premise environments.
• EDI: standardised B2B exchange with suppliers, customers and logistics partners.

What is often forgotten

Every interface needs a named owner, an SLA and a decommissioning plan from day one. Interfaces without ownership accumulate as invisible technical debt that surfaces, expensively, at the next version upgrade.
