The full answer
Most organisations already run an ERP and cannot replace it just to launch a mobile app, a customer portal or a new sales tool. Integration lets the new product use the ERP as its system of record while giving users a modern, focused experience the ERP itself cannot provide.
Creuto's approach starts with mapping the data and events that need to flow in each direction, who owns each field, and how conflicts are resolved. The team then chooses the integration method the ERP supports: REST or SOAP APIs, scheduled file exports, direct database access through views, or an integration layer that sits between systems.
Reliability matters more than speed. Integrations are built with retries, queues, idempotent updates and logging, so a network failure or a change in the ERP does not silently lose an order. Every sync is visible in an admin view, and alerts fire when something is stuck.
Creuto also builds custom ERP systems where an off-the-shelf product does not fit, as in its case study of a cloud ERP for large-scale industrial operations that unified HR, CRM, inventory and finance. Whether you integrate or replace is a discovery conversation, not a sales decision.
