ERP vendors promise connectivity; reality is uneven data quality, batch windows, and undocumented edge cases. Expect discovery—not just development.
Integrate events and facts, not every screen the ERP can render.
Myth one: “We will sync everything nightly.” Near-real-time often matters only for stock and orders; finance may still be batch. Design per domain.
Myth two: “The middleware will fix bad master data.” Middleware moves bytes; governance fixes duplicates, units, and categories.
Use dead-letter queues and reconciliation reports. Integrations fail; your operations team needs tools to see and fix discrepancies without calling engineering daily.
