BigQuery plus Ward: demand forecasting for home retail
See demand before it arrives. Ward runs it on BigQuery data over your home fleet, without a warehouse project first.
How Ward turns BigQuery data into home demand
Demand Forecasting. Ward combines historical patterns, weather data, local events, and economic signals to forecast demand at the store-SKU-day level.
A Home Improvement operator is watching 50,000+ SKUs over stores. Project-based purchasing, long-tail SKUs, and seasonal volatility. Ward manages the complexity of 50,000+ SKU environments with ease.
What Ward does with that: Ward builds store-level demand models incorporating seasonality, weather forecasts, promotional calendars, local events, and macroeconomic indicators.
Setup: Service account with BigQuery Data Viewer role. Ward runs read-only SQL queries on your schedule.
What it does
- Automatic reorder point recalculation
- Store-SKU-day level precision
- Weather-driven adjustment
- Event and holiday modeling

I pulled the spring pre-build against the last three seasons and the weather signal for the 22 Southeast stores.
| Signal | Finding |
|---|---|
seasonal_prebuild | Mulch on-hand hit 61% of plan the week temps broke 70°F |
dc_push | DC push started 9 days after the first-warm-week trigger, LY it was 2 |
attach.project | Soil and edging attach fell 18% at stores that gapped on mulch |
Recommend: tie the push trigger to the 10-day forecast instead of the calendar week, pre-position two truckloads at the 8 stores that gapped, and re-set the attach endcap.

Why Demand matters for Home retail
Home improvement demand is the most weather-dependent in retail, a warm spring can shift seasonal demand forward by weeks across a large chain. Ward integrates 10-day weather forecasts, historical correlations, and housing market indicators to predict demand at a granularity that static seasonal plans can't match.
Why this combination
is its own problem.
Demand Forecasting 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.
- 01 Seasonal calendars are set chain-wide but the actual project-season start varies 4-8 weeks across regions; Northeast deck season is meaningfully later than Southeast.
- 02 Housing market indicators (permits, sales) are leading signals for project demand but rarely make it into pharmacy or operational forecasting workflows.
Benchmarks. Home improvement seasonal forecast accuracy: 22-35% MAPE on weather-sensitive categories (paint, lawn/garden, outdoor power) is healthy. A 5-point accuracy gain typically reduces seasonal markdown by 20-30% and recovers 1-3% category revenue from better stock positioning.
What Ward has eyes on.
Ward reads any BigQuery dataset, gA4 event exports, ads data transfers from Google BigQuery on a read-only connection. Nothing is written back, and your Data Platform configuration does not change. BigQuery stays the system of record.
See demand before it arrives. Ward runs the model continuously rather than on a reporting cycle, which is why a finding lands the morning the pattern starts instead of at the end of the period.
Ward watches 50,000+ SKUs across your stores, at the store-category level rather than the chain roll-up. The metrics under watch include project basket value, seasonal accuracy, long-tail turn. A roll-up hides a single-store problem inside a healthy average, which is how project basket identification stays invisible for a quarter.
At the metric level. Ward integrates hyperlocal weather data, housing market indicators (home sales, building permits), seasonal project activation curves, and Pro customer pipeline data. Forecast accuracy is measured by department and weather-sensitivity tier.
What the first 90 days
actually look like.
-
01
Week 1: connect
Read-only credentials to Google BigQuery. Ward pulls from any BigQuery dataset, gA4 event exports, ads data transfers and starts building baselines. First findings 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 every morning 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.
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.

Frequently asked questions
Ward combines historical patterns, weather data, local events, and economic signals to forecast demand at the store-SKU-day level. For Home retail specifically, Ward monitors 50,000+ SKUs across your stores and delivers automated insight cards with root cause analysis and recommended actions.
Ward tracks Project basket value, Seasonal accuracy, Long-tail turn, Pro customer share, Attachment rate at the store-category level. Ward builds store-level demand models incorporating seasonality, weather forecasts, promotional calendars, local events, and macroeconomic indicators.
Service account with BigQuery Data Viewer role. Ward runs read-only SQL queries on your schedule. Data points include: Any BigQuery dataset, GA4 event exports, Ads data transfers, Custom ETL outputs.
Yes. Ward reads BigQuery data and combines it with contextual signals (weather, events, demographics) to generate Home-specific insight cards. No custom development required.
Ward integrates hyperlocal weather data, housing market indicators (home sales, building permits), seasonal project activation curves, and Pro customer pipeline data. Forecast accuracy is measured by department and weather-sensitivity tier.
February temperatures run well above normal across the Midwest. Ward detects early-spring project categories activating weeks ahead of plan while winter products decelerate faster than expected. Ward issues demand adjustment cards for Midwest stores: accelerate spring resets, cut winter closeout buys, and increase DC allocation of seasonal products. Stores that act capture early-season revenue that would have stocked out under the original plan.
First insight cards arrive within 48 hours of data connection. Ward needs approximately 2 weeks to establish stable baselines for your specific operation.
No. Ward sits on top of your existing stack. It is the proactive intelligence layer that watches your data continuously and delivers insight cards, so your team acts on findings instead of hunting for them.
