I pulled fall denim against last season’s curve at the same selling week. Two causes, both still fixable this week.
| Signal | Finding |
|---|---|
sell_through | Week 6 sell-through 38% vs. 52% plan, concentrated in 3 of 9 door clusters |
size_curve | Waist 30–32 sold out in 41 doors while 36–38 sits at 71% on hand |
markdown.ladder | First markdown is 3 weeks later than LY, weeks-of-supply now 11.4 |
Recommend: transfer 30–32 out of the 12 overstocked doors, hold the ladder on core indigo, and take the first markdown on light wash now while it still clears at 20%.

Why Promos matters for Fashion retail
Blanket promotions drive traffic but train customers to wait for sales. Ward measures the full cycle, demand suppression before the event, lift during, and pull-forward decline after, to reveal which promotions build revenue and which merely shift it around the calendar.
What Ward has eyes on.
The promos model runs on a daily cycle, not on a reporting calendar. It flags the pattern, traces the driver, and attaches the next step before the number reaches a review deck.
Coverage is store by store, category by category. Ward scans continuously sell-through rate, markdown %, return rate over 15,000+ SKUs and compares each store against its own baseline, not against the chain. That is the difference between knowing the footprint is fine and knowing which seven locations 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 stitches together it with external context your Data Platform does not carry: weather, local events, competitor pricing.
At the metric level. Ward measures the full promo cycle: pre-event suppression, event lift, post-event decline, new vs returning customer mix, and margin-per-unit impact. It also calculates customer-level promo dependency scores to flag at-risk segments.
Why this combination
is its own problem.
A Head of IT rarely logs into Snowflake. They read what someone else pulled out of it, two days later. Ward removes the two days and the someone else.
- 01 Margin-per-unit erosion compounds when stack-on offers (employee discount + cart promo + free shipping) trigger together, typical promo P&L doesn't track stacked effective discount.
- 02 Customer-level promo dependency is invisible at the cohort level; the top 20% of "loyalists" can be 80% promo-dependent without the chain noticing.
Benchmarks. Fashion promo events show 40-100% gross weekend lift but typically 5-25% net incrementality after pre-event suppression and pull-forward. Operators that convert blanket events to targeted-acquisition offers usually recover 200-600 bps of gross margin.
What the first 90 days
actually look like.
-
01
Week 1: connect
Read-only credentials to Snowflake. Ward pulls from any table or view in your Snowflake account, cross-database joins, historical data at any depth 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: baselines
Ward needs roughly two weeks of history per store to separate a real deviation from normal variance. During this window the daily cards are directionally right and the thresholds are still moving.
-
03
Weeks 4 to 12: steady state
Ward returns findings each day, each with the 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 findings arrive, it is how many get acted on.
