Here is promo effectiveness in plain terms. Ward measures true promotional lift net of cannibalization, pull-forward, and pantry loading.
How it runs. Ward isolates incremental volume from baseline, measures cross-SKU cannibalization, estimates pull-forward effects, and calculates true ROI.
The connection itself. Ward connects via Snowflake SQL API with key-pair authentication. Read-only warehouse. Your data never leaves Snowflake.
Key capabilities
- Cannibalization quantification
- Pull-forward detection
- Promo ROI scorecards
- Net lift measurement (not gross)

I pulled the 6–9a daypart for the 14 Route 9 sites against the chain baseline. Two causes, one of them scheduling.
| Signal | Finding |
|---|---|
daypart_sales | 6–9a revenue −11% vs. chain, coffee units −18% |
labor_scheduling | Second associate clocks in at 7:30a, peak starts 6:40a at 9 of 14 sites |
foodservice.waste | Breakfast sandwich waste 14%, hold times past 4 hours at 6 sites |
Recommend: move the second open to 6:15a at those nine sites, cut the breakfast batch by one tray, and re-check attach in two weeks.

Why Promos matters for Convenience retail
Most c-store operators accept vendor-funded promotions without measuring whether they actually improve store economics. Multi-unit deals can cannibalize single-unit margin, and rebates often don't offset the erosion. Ward measures the true P&L impact of each program, giving operators evidence for vendor negotiations.
Why this combination
is its own problem.
Snowflake is the system of record for most convenience operators of your size, which means the indicators Ward needs are already there. The gap is not data collection. It is that nobody has time to read any table or view in your Snowflake account and cross-database joins every morning across every store.
- 01 Display labor and reset cost is left out of promo P&L; on tight-staffing nights, store-level cost can exceed vendor funding.
- 02 Multi-unit price points (2-for-$3) shift demand from higher-margin single-unit purchases without showing up in event-window reporting.
Benchmarks. C-store vendor promo programs typically show 15-50% gross unit lift and 3-15% net margin lift after cannibalization, funding, and labor. Most chains run 100-300 vendor events per year; the bottom quartile is usually negative-net.
What Ward has eyes on.
Every one of your locations gets its own baseline. Ward watches transactions/hour, attach rate, basket size against it and raises only the deviations that hold up. The two that show up most in convenience retail are daypart demand variation and planogram compliance, and both are baseline problems before they are P&L problems.
The connection to Snowflake is read-only and runs on your schedule. Ward ingests any table or view in your Snowflake account, cross-database joins, and the rest of the feed, then stitches together 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 tracks unit lift vs margin impact, single-to-multi-unit cannibalization, vendor funding offset accuracy, and post-promo demand suppression, including inventory holding, labor for reset, and displaced revenue from non-promoted items.
What the first 90 days
actually look like.
-
01
Week 1: read-only connection
Ward plugs into Snowflake with read-only credentials and begins ingesting any table or view in your Snowflake account and cross-database joins. No config changes on your side. First findings arrive within 48 hours.
-
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: steady state
Ward returns daily cards daily, each with root cause and a recommended move. 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.

Ward tracks Transactions/hour, Attach rate, Basket size, Planogram compliance, Daypart mix at the store-category level. Ward isolates incremental volume from baseline, measures cross-SKU cannibalization, estimates pull-forward effects, and calculates true ROI.
Ward connects via Snowflake SQL API with key-pair authentication. Read-only warehouse. Your data never leaves Snowflake. Data points include: Any table or view in your Snowflake account, Cross-database joins, Historical data at any depth.
Yes. Ward reads Snowflake data and combines it with contextual signals (weather, events, demographics) to generate Convenience-specific insight cards. No custom development required.
Ward tracks unit lift vs margin impact, single-to-multi-unit cannibalization, vendor funding offset accuracy, and post-promo demand suppression, including inventory holding, labor for reset, and displaced revenue from non-promoted items.
A top beverage vendor runs 26 promotional events per year across the chain. Ward reveals that fewer than half generate positive net margin after accounting for cannibalization and margin erosion. Ward provides per-event ROI scorecards the category manager uses to renegotiate: fewer but deeper promotions on high-ROI events, elimination of negative-margin ones, and better vendor funding terms.
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.
