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 Stockout matters for Fashion retail
Fashion stockouts are invisible, they show up as "size not available," not "product missing," and the POS never records the lost sale. Ward monitors sell-through velocity by style-size-color-store and detects when popular size runs are depleting faster than replenishment can cover within the remaining selling window.
What Ward has eyes on.
Ward keeps a running read on 15,000+ SKUs across your locations, at the store-category level rather than the chain roll-up. The metrics under watch include sell-through rate, markdown %, return rate. A roll-up hides a single-store problem inside a healthy average, which is how markdown timing stays invisible for a quarter.
The stockout model runs every morning, not on a reporting calendar. It catches the pattern, accounts for the cause, and attaches a recommended move before the number reaches a review deck.
At the metric level. Requires style-size-color velocity tracking, sell-through benchmarking against plan, inter-store inventory visibility, and time-remaining-in-season context. Ward also flags recurring size curve inaccuracies as a planning problem distinct from replenishment.
Why this combination
is its own problem.
A generic stockout model applied to a fashion footprint produces alerts nobody trusts. The thresholds are wrong, because fashion baselines are wrong for it. Ward learns the baseline from your own locations instead of importing one.
- 01 E-commerce inventory pools are counted at the chain level but allocated by warehouse, so "in stock" online routinely cancels because the assigned DC ran dry.
- 02 Pre-season size curves are set from prior-year history and rarely re-run mid-season, locking in a misread on emerging size demand.
Benchmarks. Fashion full-price sell-through targets: 60-75% by week 6, 75-85% by week 10. Broken size runs (a key size missing while others remain) typically affect 15-25% of styles in week 4 and 30-40% by week 8 without active rebalancing.
What the first 90 days
actually look like.
-
01
Week 1: read-only connection
Ward ingests your existing systems on a read-only connection. Nothing is written back. 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
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.
