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 pulls from Lightspeed rather than replacing it. Sales transactions, inventory counts, customer profiles come across on a read-only connection, get enriched with contextual data, and come back as findings. Your POS is untouched.
The promos model runs each day, not on a reporting calendar. It spots the pattern, explains root cause, and attaches a recommended action before the number reaches a review deck.
Why this combination
is its own problem.
Promo Effectiveness needs sales transactions and inventory counts at minimum. Lightspeed Retail carries both, at the grain the model needs. That is the whole integration story: no middleware, no staging warehouse, no custom extract.
What the first 90 days
actually look like.
-
01
Week 1: connect
Read-only credentials to Lightspeed Retail. Ward ingests sales transactions, inventory counts, customer profiles 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: steady state
Ward hands you daily cards daily, each with the driver and a recommended action. Volume settles at a level a single person can read over coffee. The measure of success is not how many cards arrive, it is how many get acted on.
