Promo Effectiveness: Home retail, Snowflake data, Supply Chain decisions
You find out about stockouts after customers do. Ward catches home promos movement in your Snowflake data while it is still fixable, with root cause and the next step attached.
Promo Effectiveness for Home on Snowflake, scoped to supply chain
You find out about stockouts after customers do. Ward filters to what a VP Supply Chain can act on and drops the rest.
Promo Effectiveness. Ward measures true promotional lift net of cannibalization, pull-forward, and pantry loading.
Home Improvement changes the scale of the problem: 50,000+ SKUs, every one of your 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 isolates incremental volume from baseline, measures cross-SKU cannibalization, estimates pull-forward effects, and calculates true ROI.
Getting the data in. Ward connects via Snowflake SQL API with key-pair authentication. Read-only warehouse. Your data never leaves Snowflake.
What it does
- Pull-forward detection
- Promo ROI scorecards
- Net lift measurement (not gross)
- Cannibalization quantification

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 Promos matters for Home retail
Home improvement promos drive traffic spikes, but most promotional purchases would have happened at full price within 30 days, the customer was already planning the project. True incrementality comes from triggering project starts, not discounting items already in someone's plan.
Why this combination
is its own problem.
The supply chain problem in home retail is not missing data. It is that project basket value, seasonal accuracy, long-tail turn live in different systems on different refresh schedules, and reconciling them is a person-week. Ward does the reconciliation and hands you the two-line version.
- 01 Project-starter bundles typically generate 2-4x the basket size of equivalent single-item discounts but get treated equivalently in promo planning.
- 02 Major holiday events get evaluated on weekend revenue lift, missing 30-day pull-forward and post-event demand drag that erode net incrementality.
Benchmarks. Home improvement holiday promo events show 40-90% gross weekend lift but typically 5-25% net incrementality after pull-forward and post-event drag. Project-starter bundles usually deliver 2-4x the incremental basket value of single-item percentage-off promos.
What Ward has eyes on.
Coverage is store by store, category by category. Ward tracks project basket value, seasonal accuracy, long-tail turn across 50,000+ SKUs and compares each store against its own baseline, not against the chain. That is the difference between knowing the store base is fine and knowing which seven stores are not.
The connection to Snowflake is read-only and runs on your schedule. Ward reads any table or view in your Snowflake account, cross-database joins, and the rest of the feed, then joins it with external context your Data Platform does not carry: weather, local events, competitor pricing.
Know which promos actually work. 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.
At the metric level. Ward measures project-start incrementality, pull-forward rates by category, Pro vs DIY promotional response differences, and project basket value vs single-item sales. A 30-day pre/post window captures the full demand-shifting effect.
What the first 90 days
actually look like.
-
01
Week 1: connect
Read-only credentials to Snowflake. Ward ingests any table or view in your Snowflake account, cross-database joins, historical data at any depth and starts building baselines. First daily 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.

You find out about stockouts after customers do. Ward solves this with automated insight cards: 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.
Ward delivers daily insight cards covering Project basket value, Seasonal accuracy, Long-tail turn, tailored for Supply Chain decision-making. Each card includes what changed, why it matters, and what to do next.
Ward measures project-start incrementality, pull-forward rates by category, Pro vs DIY promotional response differences, and project basket value vs single-item sales. A 30-day pre/post window captures the full demand-shifting effect.
The Memorial Day event shows strong weekend revenue lift, but Ward's analysis reveals most of it was pull-forward from purchases that would have happened within 30 days, plus deal-seekers with below-average basket sizes. The highest-incrementality performers were project-starter bundles that triggered new project purchases. Ward recommends shifting future event strategy from broad discounts to project-starter bundles.
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.
