BigQuery plus Ward: shrinkage for a Head of IT
Find the leak before it drains you. Ward runs it off BigQuery, scoped to what a Head of IT owns.
Shrinkage Detection on BigQuery, for technology
What shrinkage detection does: Ward identifies abnormal inventory loss patterns and distinguishes between theft, damage, spoilage, and administrative error.
The business wants AI. You sign off on the architecture. Ward pulls forward the indicators that change a technology decision.
How Ward hands you Shrinkage daily cards: Ward compares expected inventory against actual counts, segments loss by cause category, and flags store-level anomalies against your estate baseline.
How the connection works. Service account with BigQuery Data Viewer role. Ward runs read-only SQL queries on your schedule.
Capabilities
- Receiving dock anomaly detection
- Pattern recognition across time
- Cause-level shrinkage attribution
- Store-vs-estate benchmarking

Ask anything. Ward routes to the right agent and returns cited answers.
I pulled Store 37’s last 28 days against the chain baseline. Two root causes, both compounding.
| Signal | Finding |
|---|---|
labor_efficiency | Rev/labor-hour −22% vs. cluster, staffing mismatch at 11a–1p peak |
inventory.fresh | Fresh fill 83%, backroom replenishment lag at 2–4p |
promo.lift | BOGO crackers cannibalized Brand Y by 28%, net category +6% |
Recommend: re-baseline Store 37 schedule against true peak, raise replen window to 1p, and review the BOGO before next cycle.

Why this combination
is its own problem.
A Head of IT rarely logs into BigQuery. They read what someone else pulled out of it, two days later. Ward removes the two days and the someone else.
What Ward has eyes on.
The shrinkage model runs every morning, not on a reporting calendar. It spots the pattern, accounts for root cause, and attaches the next step before the number reaches a review deck.
Ward reads straight from BigQuery rather than replacing it. Any BigQuery dataset, gA4 event exports, ads data transfers come across on a read-only connection, get enriched with contextual data, and come back as insight cards. Your Data Platform is untouched.
What the first 90 days
actually look like.
-
01
Week 1: read-only connection
Ward sits on top of Google BigQuery with read-only credentials and begins ingesting any BigQuery dataset and gA4 event exports. No config changes on your side. First daily cards arrive within 48 hours.
-
02
Weeks 2 to 3: calibration
Baselines stabilize per store and per category. Ward stops flagging normal variance and starts flagging exceptions. This is the window where the false positive rate drops sharply.
-
03
Weeks 4 to 12: operating rhythm
Cards arrive on a daily cycle and get triaged like any other queue. Most teams find the volume settles into something one person clears in ten minutes. What matters is the action rate, not the alert count.
How Ward connects to Google BigQuery
Ward queries BigQuery using your existing datasets. GA4 exports, POS data, CRM exports. Ward reads it where it lives.
Setup: Service account with BigQuery Data Viewer role. Ward runs read-only SQL queries on your schedule.
