BigQuery plus Ward: shrinkage for a VP Supply Chain
You find out about stockouts after customers do. Ward picks up shrinkage movement in your BigQuery data and attributes what caused it.
Shrinkage Detection on BigQuery, for supply chain
You find out about stockouts after customers do. Ward delivers findings scoped to supply chain decision-making.
What shrinkage detection does: Ward identifies abnormal inventory loss patterns and distinguishes between theft, damage, spoilage, and administrative error.
The mechanism. Ward compares expected inventory against actual counts, segments loss by cause category, and flags store-level anomalies against your estate baseline.
Getting the data in. Service account with BigQuery Data Viewer role. Ward runs read-only SQL queries on your schedule.
Capabilities
- Cause-level shrinkage attribution
- Store-vs-estate benchmarking
- Receiving dock anomaly detection
- Pattern recognition across time

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.

What Ward has eyes on.
The shrinkage model runs daily, not on a reporting calendar. It flags the pattern, accounts for the driver, and attaches a recommended action before the number reaches a review deck.
The connection to Google BigQuery is read-only and runs on your schedule. Ward reads straight from any BigQuery dataset, gA4 event exports, and the rest of the feed, then cross-references it with external context your Data Platform does not carry: weather, local events, competitor pricing.
Why this combination
is its own problem.
Shrinkage Detection needs any BigQuery dataset and gA4 event exports at minimum. Google BigQuery carries both, at the grain the model needs. That is the whole integration story: no middleware, no staging warehouse, no custom extract.
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: steady state
Ward delivers insight cards daily, each with the cause and a recommended action. Volume settles at a level a single person can read over coffee. The measure of success is not how many daily cards arrive, it is how many get acted on.
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.
