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.
Every one of your locations gets its own baseline. Ward keeps a running read on sell-through rate, markdown %, return rate against it and brings up only the deviations that hold up. The two that show up most in fashion retail are markdown timing and size curve misallocation, and both are baseline problems before they are P&L problems.
The connection to Snowflake is read-only and runs on your schedule. Ward reads straight from any table or view in your Snowflake account, cross-database joins, and the rest of the feed, then cross-references it with external context your Data Platform does not carry: weather, local events, competitor pricing.
Know before the shelf empties. 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.
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.
Stockout Prediction produces a lot of output that is technically correct and operationally useless to finance. Ward filters on whether the finding changes a decision a CFO can actually make.
- 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 A style at 82% chain sell-through can be 100% out on size M while size XL sits at 40%, chain averages hide the broken assortment that defines a customer's in-store experience.
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: connect
Read-only credentials to Snowflake. Ward reads any table or view in your Snowflake account, cross-database joins, historical data at any depth and starts building baselines. First findings 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 cards are directionally right and the thresholds are still moving.
-
03
Weeks 4 to 12: steady state
Ward sends findings on a daily cycle, each with what caused it and the next step. 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.
