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.
Why this combination
is its own problem.
Shopify / Shopify Plus is the system of record for most fashion operators of your size, which means the inputs Ward needs are already there. The gap is not data collection. It is that nobody has time to read orders & line items and product catalog every morning across every store.
- 01 Customer-level promo dependency is invisible at the cohort level; the top 20% of "loyalists" can be 80% promo-dependent without the chain noticing.
- 02 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.
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 Ward has eyes on.
Ward ingests orders & line items, product catalog, inventory levels from Shopify / Shopify Plus on a read-only connection. Nothing is written back, and your Commerce configuration does not change. Shopify stays the system of record.
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.
Coverage is store by store, category by category. Ward keeps a running read on sell-through rate, markdown %, return rate throughout 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.
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.
What the first 90 days
actually look like.
-
01
Week 1: read-only connection
Ward reads from Shopify / Shopify Plus with read-only credentials and begins ingesting orders & line items and product catalog. No config changes on your side. First findings arrive within 48 hours.
-
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: operating rhythm
Insight cards arrive on a daily cycle 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.
