Demand Forecasting for Grocery on BigQuery, built for technology
See demand before it arrives. Ward runs it on BigQuery data across your grocery footprint, scoped to technology.
How a grocery Head of IT runs demand on Google BigQuery
Demand Forecasting, in one sentence. Ward combines historical patterns, weather data, local events, and economic signals to forecast demand at the store-SKU-day level.
In a Grocery & Supermarket estate the job is 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.
The business wants AI. You sign off on the architecture. Ward returns findings scoped to technology decision-making.
How it runs. 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.
Why this combination
is its own problem.
Demand Forecasting produces a lot of output that is technically correct and operationally useless to technology. Ward filters on whether the finding changes a decision a Head of IT can actually make.
- 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 Promo lift gets baked into baseline forecasts, so the next non-promo week is over-ordered and produces shrink.
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 Ward has eyes on.
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 cards. Your Data Platform is untouched.
The demand model runs each day, not on a reporting calendar. It detects the pattern, explains the driver, and attaches what to do about it before the number reaches a review deck.
Every one of your stores gets its own baseline. Ward monitors fill rate, shrinkage %, fresh waste % against it and brings up 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. 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.
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
Insight cards arrive daily 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.
