Promo Effectiveness on Power BI, for e-commerce
Ward pulls from power BI REST API datasets, underlying SQL/Azure data, dataflow outputs from Microsoft Power BI, runs promos on it, and delivers the e-commerce read every morning.
Promo Effectiveness on Power BI, for e-commerce
Here is promo effectiveness in plain terms. Ward measures true promotional lift net of cannibalization, pull-forward, and pantry loading.
Your online and offline data live in different worlds. Ward returns insight cards scoped to e-commerce decision-making.
Under the hood. Ward isolates incremental volume from baseline, measures cross-SKU cannibalization, estimates pull-forward effects, and calculates true ROI.
The connection itself. Ward connects to the same data sources Power BI uses. Or reads Power BI datasets via REST API. Your reports stay untouched.
Key capabilities
- Cannibalization quantification
- Pull-forward detection
- Promo ROI scorecards
- Net lift measurement (not gross)

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 this combination
is its own problem.
Promo Effectiveness needs power BI REST API datasets and underlying SQL/Azure data at minimum. Microsoft Power BI carries both, at the grain the model needs. That is the whole integration story: no middleware, no staging warehouse, no custom extract.
What Ward has eyes on.
The promos model runs each day, not on a reporting calendar. It catches the pattern, accounts for the driver, and attaches a recommended action before the number reaches a review deck.
The connection to Microsoft Power BI is read-only and runs on your schedule. Ward pulls from power BI REST API datasets, underlying SQL/Azure data, and the rest of the feed, then joins it with external context your BI does not carry: weather, local events, competitor pricing.
What the first 90 days
actually look like.
-
01
Week 1: connect
Read-only credentials to Microsoft Power BI. Ward reads straight from power BI REST API datasets, underlying SQL/Azure data, dataflow outputs and starts building baselines. First 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 each day 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.
