VP Supply Chain: grocery demand, read from Google BigQuery
See demand before it arrives. Ward runs it on BigQuery data over your grocery footprint, scoped to supply chain.
Demand Forecasting for Grocery on BigQuery, scoped to supply chain
Grocery & Supermarket changes the scale of the problem: 30,000+ SKUs, every one of your stores. Fresh availability, shrinkage, and promo effectiveness across hundreds of stores. Ward monitors perishable turn rates and flags waste before it happens.
You find out about stockouts after customers do. Ward hands back daily cards scoped to supply chain decision-making.
Demand Forecasting is a card type Ward runs continuously. Ward combines historical patterns, weather data, local events, and economic signals to forecast demand at the store-SKU-day level.
Under the hood. Ward builds store-level demand models incorporating seasonality, weather forecasts, promotional calendars, local events, and macroeconomic indicators.

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 Demand matters for Grocery retail
Perishable inventory creates an asymmetric cost function, over-ordering causes waste, under-ordering causes stockouts, both within a 48-72 hour window. Ward builds store-SKU-day models incorporating hyperlocal weather, community events, and holiday patterns to tighten the ordering window beyond what weekly aggregates can deliver.
What Ward has eyes on.
The demand model runs daily, not on a reporting calendar. It catches the pattern, traces the driver, and attaches a recommended move before the number reaches a review deck.
Every one of your stores gets its own baseline. Ward scans continuously 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.
Ward reads 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.
At the metric level. Precision depends on perishable turn-rate modeling, weather-demand correlation by category, promotional lift isolation, and event demand pattern libraries. Ward measures forecast accuracy at WMAPE by department and flags when accuracy degrades below threshold.
Why this combination
is its own problem.
A generic demand model applied to a grocery store base produces alerts nobody trusts. The thresholds are wrong, because grocery baselines are wrong for it. Ward learns the baseline from your own stores instead of importing one.
- 01 Holiday calendars are set at the chain level; floating holidays (Easter, Ramadan, Lunar New Year) shift demand by 20-40% in affected stores but barely move the chain forecast.
- 02 New-item launches use a category-average curve when in reality the lift profile differs by ethnic mix and pricing tier.
Benchmarks. Healthy grocery WMAPE runs 18-25% at the store-SKU-week grain and 28-40% at store-SKU-day. Fresh departments are noisier (35-55%). A 5-point WMAPE improvement on top-200 SKUs typically saves 0.5-1.2% of fresh COGS in shrink.
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 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: baselines
Ward needs roughly two weeks of history per store to separate a real deviation from normal variance. During this window the cards are directionally right and the thresholds are still moving.
-
03
Weeks 4 to 12: steady state
Ward returns insight cards each day, each with the driver and what to do about it. 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

You find out about stockouts after customers do.
- ×Demand forecasts are off by 15-25% and nobody catches it until the shelf is empty
- ×Supplier fill rate problems announce themselves at the receiving dock
- ×Safety stock levels get set once a year and left alone
- ×No early warning system for supply chain disruptions
- ×Replenishment exceptions require manual triage every morning
- ✓Stockout prediction cards arrive 24-72 hours before empty shelves
- ✓Supplier fill rate tracking with automatic escalation
- ✓Dynamic safety stock recommendations based on current demand signals
- ✓Weather, event, and macro-driven demand adjustments
- ✓Replenishment exceptions auto-prioritized by revenue impact
