Mobile scanning happens at the edge; the ERP remains the financial and inventory system of record.
Edge vs core responsibilities
Middleware should validate, sequence, and batch edge events instead of forwarding every scan directly to the ERP API.
Offline queue design
Production warehouses lose connectivity routinely. Design for durable local storage, ordered replay, and visible queue health.
Idempotent ERP posting
Use idempotency keys or document-level deduplication so retries after offline sync do not double-post receipts or adjustments.
Validation before write-back
Block invalid combinations early: unknown SKU, wrong location, quantity over tolerance, serial already consumed.
