Shrinkage Detection for Fashion on Snowflake, built for technology
Find the leak before it drains you. Ward runs it on Snowflake data throughout your fashion fleet, scoped to technology.
How a fashion Head of IT runs shrinkage on Snowflake
What shrinkage detection does: Ward identifies abnormal inventory loss patterns and distinguishes between theft, damage, spoilage, and administrative error.
A Fashion & Apparel operator is monitoring 15,000+ SKUs across locations. Seasonal sell-through, size curve optimization, and markdown timing. Ward monitors style velocity and flags slow movers before the window closes.
The business wants AI. You sign off on the architecture. Ward brings up the signals that change a technology decision.
What Ward does with that: Ward compares expected inventory against actual counts, segments loss by cause category, and flags store-level anomalies against your estate baseline.
The connection itself. Ward connects via Snowflake SQL API with key-pair authentication. Read-only warehouse. Your data never leaves Snowflake.
What it does
- Receiving dock anomaly detection
- Pattern recognition across time
- Cause-level shrinkage attribution
- Store-vs-estate benchmarking

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 Shrinkage matters for Fashion retail
The biggest hidden source of fashion shrinkage isn't theft, it's administrative error in transfer-heavy operations where every handoff between stores, e-commerce, and returns is a reconciliation risk. Ward tracks inventory movements across all channels and distinguishes transfer discrepancies from return fraud and genuine theft.
Why this combination
is its own problem.
Snowflake was built for transactions, not for technology decisions. The data is right there and it is in the wrong shape. Ward reads any table or view in your Snowflake account and cross-database joins and rewrites them as a decision.
- 01 Return fraud and wardrobing get logged as legitimate returns because store associates lack the data to challenge them in real time.
- 02 Inter-store transfers get scanned as "received" without case opening, so vendor short-shipments only surface at the next physical inventory.
Benchmarks. Fashion shrink runs 1.4-2.5% of sales, with returns/wardrobing in premium tiers contributing 0.4-0.8% of that. High-value categories (handbags, outerwear, premium denim) account for 40-60% of total dollar shrink despite being 10-20% of unit volume.
What Ward has eyes on.
Ward pulls from any table or view in your Snowflake account, cross-database joins, historical data at any depth from Snowflake on a read-only connection. Nothing is written back, and your Data Platform configuration does not change. Snowflake stays the system of record.
The shrinkage model runs every morning, not on a reporting calendar. It flags the pattern, accounts for the cause, and attaches the next step before the number reaches a review deck.
Every one of your locations gets its own baseline. Ward keeps a running read on sell-through rate, markdown %, return rate against it and surfaces 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.
At the metric level. Ward tracks transfer accuracy rates, return-to-sale ratios, inter-store reconciliation gaps, and high-value item movement patterns. Separating operational shrinkage from intentional loss is essential because the interventions are completely different.
What the first 90 days
actually look like.
-
01
Week 1: read-only connection
Ward plugs into Snowflake with read-only credentials and begins ingesting any table or view in your Snowflake account and cross-database joins. No config changes on your side. First daily cards arrive inside the first 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
Findings arrive daily 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.

Yes. Ward reads Snowflake data and combines it with contextual signals (weather, events, demographics) to generate Fashion-specific insight cards. No custom development required.
The business wants AI. You sign off on the architecture. Ward solves this with automated insight cards: Federated query: data stays in your warehouse. No copies, no shadow lake. Read-only credentials. Cedar policies enforce least-privilege per agent. LLM-agnostic. Anthropic, OpenAI, Gemini, Ollama. Bring your own keys.
Ward delivers daily insight cards covering Sell-through rate, Markdown %, Return rate, tailored for Technology decision-making. Each card includes what changed, why it matters, and what to do next.
Ward tracks transfer accuracy rates, return-to-sale ratios, inter-store reconciliation gaps, and high-value item movement patterns. Separating operational shrinkage from intentional loss is essential because the interventions are completely different.
Ward flags a cluster of stores where high-value item returns run well above estate average, most without original tags, with the same payment cards appearing across multiple locations. The pattern matches a wardrobing ring. LP adjusts the return policy for flagged categories and sees a significant drop in high-value returns within weeks.
First insight cards arrive within 48 hours of data connection. Ward needs approximately 2 weeks to establish stable baselines for your specific operation.
No. Ward sits on top of your existing stack. It is the proactive intelligence layer that watches your data continuously and delivers insight cards, so your team acts on findings instead of hunting for them.
