Get a project estimateWhat makes fashion commerce different
Every fashion product is really a grid of sizes and colours, each with its own stock. Collections change with the seasons, end-of-season sales clear what's left, and a large share of orders come back because of fit.
We build fashion commerce around that reality: variant-aware catalogues and stock, size guidance tied to garment measurements, exchange-first returns and fast image-led browsing on mobile. For brands with stores, the same inventory feeds counters, the website and marketplaces.
Challenges
Pain points in apparel operations
Fit-driven returns
Size confusion leads to exchanges and returns that cost two shipments.
Broken size runs
Popular sizes sell out while others linger, and online stock doesn't reflect store holdings.
Catalogue workload
Every drop needs photography, measurements and variant setup across channels.
Short product life
Collections must sell through before the season ends or be marked down.

How it works
How a fashion order handles fit and exchanges
Size-level stock and exchange-first rules stop a wrong size from becoming a lost sale.
- Shopper app
Step 1: Shopper checks the size guide
Garment measurements and fit notes for that style, plus a suggestion based on what they kept before, guide the choice.
- Inventory service
Step 2: Order reserves one exact variant
Stock is held by size and colour across the warehouse, stores and marketplaces, so the reserved piece is really available.
- Warehouse or store
Step 3: Shipped from wherever the size is
If the warehouse is out of that size, a store that holds it can fulfil the order.
- Customer
Step 4: Customer asks for another size
The replacement size is reserved immediately, so it can't sell out while the original travels back.
- Courier and QC staff
Step 5: Reverse pickup and quality check
Once the pickup is scanned and the item checked, the new size ships and the return reason is logged.
- Merchandising team
Step 6: Size charts get corrected
Styles with frequent fit returns are flagged, so the size chart or fit note can be fixed for the rest of the season.

Plain-English glossary
Fashion commerce terms, in plain English
- Variant matrix
- The grid of sizes and colours for one style, each with its own stock, images and barcode. Modelling it properly is what stops the site showing a size that has actually sold out.
- Size run
- The spread of sizes bought for a style, for example S to XXL in set ratios. Tracking how each size sells tells your buyers how to split the next purchase.
- Reverse pickup
- The courier collects a return or exchange from the customer's address. The pickup scan is the trigger to release the replacement size, so timing matters.
- End-of-season sale (EOSS)
- The markdown period that clears a collection before the next one arrives. Stock visibility by size and location decides what to discount, how deeply and where.
Product preview
Screens for shoppers and your merchandising team
Shopper app. Product pages show garment measurements and fit notes for each style, which answers the size question before it turns into a return. 
Shopper app. Customers swap sizes in a few taps, and the new size is held for them while the original is collected, so the exchange does not end in a refund. 
Merchandising panel. Merchandisers see return reasons by style and fix the few styles causing most fit returns, often with a corrected size chart rather than a new tool.

FAQ
Frequently asked questions
Can size recommendations reduce returns?
They can help, though no tool removes fit returns entirely. The most dependable approach is accurate garment measurements per style, clear fit notes such as runs small, and suggestions based on what a customer kept or exchanged before. We capture return reasons in a structured way, so you can spot styles with sizing problems and fix the size chart, which often helps more than a clever algorithm.
How do you handle exchanges without losing the sale?
When a customer requests a different size, the system reserves that variant immediately so it can't sell out while the original item travels back. The replacement ships once the reverse pickup is scanned, or straight away for trusted customers, depending on your rules. If the size isn't available, the customer is offered store credit or a refund, and every step updates stock across channels.
Can the same system run our stores and our website?
Yes. A shared inventory service can power store billing, the website, apps and marketplace listings, with stock held per location. Online orders can be fulfilled from a store when the warehouse is out, and customers can return online purchases in a store. Fashion brands often gain the most here, because size-level stock is spread thinly across locations.
