The Problem
A SaaS layer that builds a cryptographically verifiable, near‑real‑time “truth twin” of inventory across ERP, WMS, POS, 3PL, and e‑commerce channels. ITT continuously reconciles stock using probabilis

- Celigo Integrator.io
Must-Have Features for MVP
Streaming reconciliation across ERP, WMS, POS, 3PL, e‑commerce using CDC/webhooks
Bayesian identity resolution for SKUs/variants/pack sizes and serial/lot mapping
Root‑cause graph with financial impact scoring and recommended fixes
Atomic correction writer with ERP‑specific adapters and rollback
Confidence‑based guardrails (auto‑hold picks/ASN/PO until resolved)
Cycle count optimizer that targets highest expected variance
UoM and conversion anomaly detector (catch pack/each errors)
Audit‑proof ledger of corrections with cryptographic hash chaining
What‑if simulation to test corrections before posting
⚠️ Potential Challenges
- Dirty and inconsistent master data (SKUs, UoM, locations)
- ERP API rate limits and posting constraints
- Resistance to auto‑posting corrections
- Complex multi‑entity/3PL cutoffs and lead‑time drift
Risk Level: Moderate
🎯 Keys to Success
- >90% reduction in unresolved variances in 30 days
- <24‑hour reconciliation lag across all channels
- 50%+ reduction in inventory write‑offs quarter over quarter
- Measured stockout reduction and service level lift
- Audit acceptance with zero material weaknesses tied to inventory
