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.
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.
Ward monitors 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 connection to Shopify / Shopify Plus is read-only and runs on your schedule. Ward ingests orders & line items, product catalog, and the rest of the feed, then stitches together it with external context your Commerce does not carry: weather, local events, competitor pricing.
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.
Shopify / Shopify Plus was built for transactions, not for store operations decisions. The data is right there and it is in the wrong shape. Ward pulls from orders & line items and product catalog and rewrites them as a decision.
- 01 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.
- 02 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.
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 sits on top of Shopify / Shopify Plus with read-only credentials and begins ingesting orders & line items and product catalog. No config changes on your side. First daily cards arrive in two days.
-
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 insight cards are directionally right and the thresholds are still moving.
-
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.
