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.
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 estate is fine and knowing which seven locations are not.
Ward reads straight from orders, products & variants, customers from BigCommerce on a read-only connection. Nothing is written back, and your Commerce configuration does not change. BigCommerce stays the system of record.
The promos model runs every morning, not on a reporting calendar. It catches the pattern, attributes the cause, and attaches what to do about it before the number reaches a review deck.
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.
Promo Effectiveness produces a lot of output that is technically correct and operationally useless to technology. Ward filters on whether the finding changes a decision a Head of IT can actually make.
- 01 Promo ROI gets calculated on event-window revenue only, missing the pre-event demand drag and post-event pull-forward decline that erode net incrementality.
- 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 the first 90 days
actually look like.
-
01
Week 1: read-only connection
Ward reads from BigCommerce with read-only credentials and begins ingesting orders and products & variants. No config changes on your side. First findings arrive within 48 hours.
-
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
Findings 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.
