Stockout Prediction for Grocery on BigQuery, built for supply chain
A grocery VP Supply Chain on BigQuery should not be hunting for stockout problems. Ward brings up them daily.
How a grocery VP Supply Chain runs stockout on Google BigQuery
You find out about stockouts after customers do. Ward hands you daily cards scoped to supply chain decision-making.
Stockout Prediction is a card type Ward runs continuously. Ward detects SKUs trending toward zero-on-hand and alerts your team with replenishment recommendations before customers notice.
Applied to Grocery & Supermarket, the surface area is 30,000+ SKUs across stores. Fresh availability, shrinkage, and promo effectiveness across hundreds of stores. Ward monitors perishable turn rates and flags waste before it happens.
How it runs. Ward analyzes sell-through velocity, current inventory levels, lead times, and supplier reliability to predict stockouts 24-72 hours before they occur.
The connection itself. Service account with BigQuery Data Viewer role. Ward runs read-only SQL queries on your schedule.
The short list
- Automated replenishment recommendations
- Supplier-aware lead time modeling
- Priority ranking by revenue impact
- Reduce lost sales by catching gaps early

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 Stockout matters for Grocery retail
Grocery stockouts train customers to switch stores, not brands, and perishable supply chains leave almost no margin for error. Ward models sell-through velocity at the store-SKU-hour level, factoring in day-of-week seasonality, weather, and supplier lead-time variability to flag gaps before they materialize.
What Ward has eyes on.
The connection to Google BigQuery is read-only and runs on your schedule. Ward ingests any BigQuery dataset, gA4 event exports, and the rest of the feed, then joins it with external context your Data Platform does not carry: weather, local events, competitor pricing.
The stockout model runs daily, not on a reporting calendar. It picks up the pattern, explains root cause, and attaches a recommended action before the number reaches a review deck.
Every one of your stores gets its own baseline. Ward keeps a running read on fill rate, shrinkage %, fresh waste % against it and raises only the deviations that hold up. The two that show up most in grocery retail are fresh waste & spoilage and on-shelf availability gaps, and both are baseline problems before they are P&L problems.
At the metric level. Critical metrics: sell-through velocity by daypart, DC-to-store lead time variance, supplier OTIF rates, and substitution elasticity. Ward tracks all four because a replenishment overreaction creates waste that compounds the original stockout cost.
Why this combination
is its own problem.
A VP Supply Chain in grocery retail owns numbers that move faster than the reporting cycle that covers them. Fill rate, shrinkage %, fresh waste % shift store by store, every morning. A monthly pack cannot represent that. You find out about stockouts after customers do.
- 01 Holiday lift factors are set at the chain level when the actual lift varies 30-200% by ethnic mix and store cluster.
- 02 Flat case-pack sizing across stores ignores 5x velocity differences between urban flagships and suburban locations.
Benchmarks. Healthy grocery on-shelf availability runs 95-98% by department, with fresh dipping to 88-92% in the closing daypart. A single percentage point drop on top-50 SKUs typically maps to 0.3-0.5% revenue erosion; the same drop on milk or eggs is closer to 0.8% because basket abandonment compounds.
What the first 90 days
actually look like.

01
Week 1: connect
Read-only credentials to Google BigQuery. Ward ingests any BigQuery dataset, gA4 event exports, ads data transfers and starts building baselines. First cards land inside 48 hours, before baselines are stable, so you can see the shape of the output early.

02
Weeks 2 to 3: baselines
Ward needs roughly two weeks of history per store to separate a real deviation from normal variance. During this window the insight cards are directionally right and the thresholds are still moving.
-
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.
