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 Fill Rate matters for Fashion retail
Fashion fill rate must be measured at the style-size-color level. A store can hold 200 units of a dress and zero in the most popular size, technically "in stock," functionally a stockout. Ward surfaces broken assortments where key sizes are missing from otherwise healthy inventory positions.
What Ward has eyes on.
The connection to Shopify / Shopify Plus is read-only and runs on your schedule. Ward pulls from orders & line items, product catalog, and the rest of the feed, then joins it with external context your Commerce does not carry: weather, local events, competitor pricing.
The fill rate model runs every morning, not on a reporting calendar. It detects the pattern, explains the cause, and attaches a recommended action before the number reaches a review deck.
Coverage is store by store, category by category. Ward scans continuously sell-through rate, markdown %, return rate over 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.
At the metric level. Ward tracks style-size-color availability, broken assortment rates, size-level sell-through velocity, and transfer opportunity value. It distinguishes supply-driven stockouts from allocation-driven gaps where inventory exists but sits in the wrong stores.
Why this combination
is its own problem.
Fill Rate Monitoring behaves differently in fashion retail than it does anywhere else. The store base shape, the SKU count, and the speed of the category all change what counts as a real data point and what is noise. Ward is tuned to the fashion version.
- 01 Fill rate measured at the style level masks size brokenness, which is what the customer actually experiences in the fitting room.
- 02 OMS shows "in stock" when size XL is the only thing left; conversion craters but the dashboard reports availability.
Benchmarks. Healthy fashion size-level availability runs 85-92% on top styles by week 6 and 70-80% by week 10. Operators with active size rebalancing typically maintain 5-10 percentage points higher size-level availability and recover 2-4 points of full-price sell-through.
What the first 90 days
actually look like.
-
01
Week 1: connect
Read-only credentials to Shopify / Shopify Plus. Ward ingests orders & line items, product catalog, inventory levels and starts building baselines. First cards 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 daily cards are directionally right and the thresholds are still moving.
-
03
Weeks 4 to 12: steady state
Ward returns cards each day, each with the cause and a recommended action. 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.
