Promo Effectiveness on Power BI, for finance
Ward reads straight from power BI REST API datasets, underlying SQL/Azure data, dataflow outputs from Microsoft Power BI, runs promos on it, and sends the finance read every morning.
How a CFO runs promos off Microsoft Power BI
Your P&L surprises are born on the store floor. Ward writes the finding at the altitude a CFO works at.
Promo Effectiveness is a card type Ward runs continuously. Ward measures true promotional lift net of cannibalization, pull-forward, and pantry loading.
What Ward does with that: Ward isolates incremental volume from baseline, measures cross-SKU cannibalization, estimates pull-forward effects, and calculates true ROI.
Setup: Ward connects to the same data sources Power BI uses. Or reads Power BI datasets via REST API. Your reports stay untouched.
Key capabilities
- Pull-forward detection
- Promo ROI scorecards
- Net lift measurement (not gross)
- Cannibalization quantification

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.

What Ward has eyes on.
Ward reads power BI REST API datasets, underlying SQL/Azure data, dataflow outputs from Microsoft Power BI on a read-only connection. Nothing is written back, and your BI configuration does not change. Power BI stays the system of record.
The promos model runs daily, not on a reporting calendar. It picks up the pattern, traces the cause, and attaches what to do about it before the number reaches a review deck.
Why this combination
is its own problem.
A CFO does not need the promos model explained. They need to know which stores moved, why, and what to do by end of day. Ward writes the finding at that altitude.
What the first 90 days
actually look like.
-
01
Week 1: read-only connection
Ward plugs into Microsoft Power BI with read-only credentials and begins ingesting power BI REST API datasets and underlying SQL/Azure data. No config changes on your side. First insight cards arrive in two days.
-
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 sends daily cards each day, each with what caused it and the next step. Volume settles at a level a single person can read over coffee. The measure of success is not how many findings arrive, it is how many get acted on.
