Fill Rate Monitoring for Fashion on BigCommerce, built for merchandising
A fashion VP Merchandising on BigCommerce should not be hunting for fill rate problems. Ward raises them every morning.
How a fashion VP Merchandising runs fill rate on BigCommerce
What fill rate monitoring does: Ward monitors on-shelf availability across your entire estate and flags stores or categories dropping below threshold.
Fashion & Apparel changes the scale of the problem: 15,000+ SKUs, every one of your locations. Seasonal sell-through, size curve optimization, and markdown timing. Ward monitors style velocity and flags slow movers before the window closes.
Your category managers are drowning in spreadsheets. Ward filters to what a VP Merchandising can act on and drops the rest.
The mechanism. Ward tracks expected vs actual on-shelf availability at the store-category level and escalates when fill rate drops below configurable thresholds.
Setup: Ward connects via BigCommerce REST API with OAuth. Webhooks for real-time order and inventory events.
What it does
- Category-level drill-down
- Estate-wide fill rate dashboard
- Threshold-based alerting
- 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 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.
Coverage is store by store, category by category. Ward scans continuously sell-through rate, markdown %, return rate across 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.
Ward pulls from BigCommerce rather than replacing it. Orders, products & variants, customers come across on a read-only connection, get enriched with contextual data, and come back as findings. Your Commerce is untouched.
Every empty shelf is a lost sale. 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. 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.
A generic fill rate model applied to a fashion estate produces alerts nobody trusts. The thresholds are wrong, because fashion baselines are wrong for it. Ward learns the baseline from your own locations instead of importing one.
- 01 Inter-store transfer thresholds are set on freight cost rather than at-risk full-price revenue; the math usually justifies more transfers than ops authorizes.
- 02 Fill rate measured at the style level masks size brokenness, which is what the customer actually experiences in the fitting room.
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: read-only connection
Ward connects to BigCommerce with read-only credentials and begins ingesting orders and products & variants. No config changes on your side. First findings 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: steady state
Ward hands you findings on a daily cycle, each with root cause and what to do about it. Volume settles at a level a single person can read over coffee. The measure of success is not how many insight cards arrive, it is how many get acted on.
How Ward connects to BigCommerce
Ward connects to BigCommerce for omnichannel retailers running headless or traditional storefronts. Orders, catalog, and customer data drive insight cards.
Setup: Ward connects via BigCommerce REST API with OAuth. Webhooks for real-time order and inventory events.
