Shopify inventory sync route
Goal
Keep storefront availability aligned with real sellable stock across connected systems.
Use this route when
- Oversells or false “in stock” signals occur.
- ERP/3PL and Shopify counts diverge.
- Retries create duplicate or stale writes.
Readiness checklist
- [ ] One source-of-truth hierarchy is documented.
- [ ] SKU key normalization is complete.
- [ ] Idempotency key strategy exists for every stock write.
- [ ] High-risk SKUs are tagged for manual spot checks.
Execution sequence (5 steps)
- Schema lock: normalize SKU, location, quantity, and timestamp fields.
- Write contract: enforce idempotent updates with deterministic keys.
- Drift detector: compare Shopify vs source-of-truth counts at fixed intervals.
- Mismatch policy: auto-resync low-risk deltas, escalate high-risk deltas.
- Incident log: store mismatch class, root cause, and remediation action.
Verification
Track these for one week:
- mismatch rate by location
- oversell incidents
- auto-resync success rate
- manual intervention count
Pass condition: mismatch and oversell trend down with no hidden failure spikes.
Expected output
An inventory reliability packet: sync contract, escalation rulebook, and weekly KPI dashboard.
Decision handoff
- If mismatch mostly originates from queue delays: go to workflow orchestration.
- If mismatch originates from poor alerting: go to observability runbooks.
Monetization-fit tool path
- Deploy troubleshooting for sync-release incidents.
- Deploy verify for pre/post sync validation.
- Internal linking checklist to connect inventory SOP pages and runbooks.
