System integration
Integration of ERP, CRM, e-commerce, finance and legacy systems via APIs, events, files and middleware — with reconciliation and monitoring.
Make separate systems agree on the same facts.
6 deliverables, a 4-stage approach and 6 related technologies.
Overview
Integrations fail quietly: a record that did not sync, a duplicate that was created twice, a field that changed format. Reliable integration design assumes failures will happen and makes them visible.
We design integrations with clear system-of-record ownership, idempotent message handling, retries with dead-letter queues, reconciliation reports and alerts.
What we deliver
- Integration architecture and data ownership map
- Connectors and transformations
- Event or queue infrastructure
- Retry and dead-letter handling
- Reconciliation reports
