A complete Shopify Plus ERP or CRM solution is not a list of endpoint names. It defines the source of truth for products, stock, orders, customers, marketing consent, and finance. A cross-border store must also handle currency, duties, multiple locations, refunds, privacy permissions, and recovery. A data dictionary and sync contract are more useful than a “seamless” claim.
Assign object and field ownership
Create a table for object, field, source, destination, version, update time, conflict rule, and owner. Inventory needs reservations, cancellation, and partial fulfilment; orders need declines, refunds, splits, and returns; customers need consent, access, and deletion.
Set event and batch boundaries
Choose webhook, API, batch, or approval by freshness and risk. Add unique keys, retries, dead-letter logs, alerts, and a human queue, and replay ordering, duplicates, timeouts, partial success, and permission changes.
Accept through reconciliation and recovery
Define latency, failure, reconciliation variance, manual work, and recovery time. Prepare small-batch data, monitoring, rollback, and contacts before launch. Without evidence, do not claim zero latency or a fixed efficiency lift.
FAQ
How should ERP, CRM, and Shopify share responsibility?
Assign one source of truth per object and field to prevent overwrites.
What fails most often in integrations?
Duplicate events, ordering, stock drift, unsynchronised refunds, broad permissions, and missing hand-off.
Must all data sync in real time?
No. Choose method by risk, freshness, and approval needs.
What should cross-border integration test?
Products, stock, orders, refunds, currency, duties, warehouses, and customer permissions.
How should “efficient” be evidenced?
Define objects, period, error, monitoring, recovery, and permission instead of a vague efficiency number.
