Grocery stockout from BigQuery, briefed to merchandising
A grocery VP Merchandising on BigQuery should not be hunting for stockout problems. Ward raises them daily.
The full picture: grocery stockout, BigQuery data, Merchandising decisions
Your category managers are drowning in spreadsheets. Ward delivers daily cards scoped to merchandising 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.
A Grocery & Supermarket operator is tracking 30,000+ SKUs over 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.
How the connection works. Service account with BigQuery Data Viewer role. Ward runs read-only SQL queries on your schedule.

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.
Ward tracks 30,000+ SKUs across your stores, at the store-category level rather than the chain roll-up. The metrics under watch include fill rate, shrinkage %, fresh waste %. A roll-up hides a single-store problem inside a healthy average, which is how fresh waste & spoilage stays invisible for a quarter.
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 findings. Your Data Platform is untouched.
The stockout model runs each day, not on a reporting calendar. It picks up the pattern, attributes root cause, and attaches a recommended action before the number reaches a review deck.
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.
The merchandising problem in grocery retail is not missing data. It is that fill rate, shrinkage %, fresh waste % live in different systems on different refresh schedules, and reconciling them is a person-week. Ward does the reconciliation and hands back the two-line version.
- 01 Holiday lift factors are set at the chain level when the actual lift varies 30-200% by ethnic mix and store cluster.
- 02 DSD vendors operate outside the WMS, so milk and bread stockouts never show up in the daily exception report.
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 reads any BigQuery dataset, gA4 event exports, ads data transfers and starts building baselines. First insight cards land inside 48 hours, before baselines are stable, so you can see the shape of the output early.
-
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
Daily 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.

Your category managers are drowning in spreadsheets.
- ×Promo planning still runs off last year's playbook
- ×Assortment reviews happen quarterly when they should happen daily
- ×Price changes chase the market a week behind it
- ×No visibility into true cannibalization across categories
- ×Vendor negotiations lack real-time sell-through evidence
- ✓Insight cards flag promo cannibalization the day it happens
- ✓Assortment gaps and whitespace opportunities surface automatically
- ✓Price elasticity shifts detected before margin erosion compounds
- ✓Category-level performance cards replace manual spreadsheet reviews
- ✓Vendor scorecards generated from actual fill rate and quality data
