Shopify plus Ward: stockout prediction for fashion retail
Your Shopify data already carries the stockout data point. Ward reads straight from it, traces what caused it, and attaches a recommended move.
How Ward turns Shopify data into fashion stockout
Stockout Prediction is a card type Ward runs continuously. Ward detects SKUs trending toward zero-on-hand and alerts your team with replenishment recommendations before customers notice.
In a Fashion & Apparel estate the job is 15,000+ SKUs throughout locations. Seasonal sell-through, size curve optimization, and markdown timing. Ward monitors style velocity and flags slow movers before the window closes.
How Ward hands back Stockout cards: Ward analyzes sell-through velocity, current inventory levels, lead times, and supplier reliability to predict stockouts 24-72 hours before they occur.
How the connection works. OAuth-based connection. Ward reads via Shopify Admin GraphQL API. Real-time webhooks for order and inventory events.

- Automated replenishment recommendations
- Supplier-aware lead time modeling

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.
Every one of your locations gets its own baseline. Ward watches sell-through rate, markdown %, return rate against it and raises 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.
Ward reads straight from Shopify rather than replacing it. Orders & line items, product catalog, inventory levels come across on a read-only connection, get enriched with contextual data, and come back as findings. Your Commerce is untouched.
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.
Running Ward on Shopify in a fashion estate skips the usual first step. There is no ingestion project, because Shopify / Shopify Plus already holds orders & line items, product catalog, inventory levels. Ward reads straight from what is there.
- 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 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 plugs into Shopify / Shopify Plus with read-only credentials and begins ingesting orders & line items and product catalog. No config changes on your side. First cards arrive inside the first 48 hours.
-
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 hands back insight cards daily, each with the cause and the next step. Volume settles at a level a single person can read over coffee. The measure of success is not how many daily cards arrive, it is how many get acted on.
