The fashion inventory nightmare
Three storefronts, one ERP, and zero tolerance for overselling
Fashion is inventory-intensive. Styles, colors, sizes, seasonal collections. Keep inventory hidden and you lose sales. Oversell and you anger customers. Let your ERP and eCommerce platform run independently and you choose chaos.
APC had three storefronts pulling from a single RLM ERP. When a customer bought a style in one color/size across all three channels, RLM needed to know. When warehouse inventory moved, the website needed visibility within minutes.
Add the complexity of contemporary fashion product taxonomy: every style in multiple colors, every color in multiple sizes. Manage this as individual SKUs and the product page becomes unusable. Configurable products are the only solution – but only if your system displays them correctly.
Architecture
Custom RLM connector with bidirectional sync
We built a custom RLM connector that pulled inventory and product attributes from the ERP every hour, updating Magento automatically. When orders were placed, they pushed back to RLM with customer info, fulfillment method, and stock location.
Eight store views handled regional pricing, currencies, and languages. Each regional brand felt independent while sharing the product catalog and infrastructure.
What we delivered
From RLM update to storefront in real time
Bidirectional RLM ERP connector
Inventory updates, product changes, and attributes sync every hour. Orders push back to RLM with fulfillment method and location. Operations never manually sync data.
Configurable products that display cleanly
Customers see a style with color and size options – not 47 individual SKUs. Color swatches work. Size limits prevent overselling. Variant management stays clean.
Omnichannel fulfillment routing
Customers choose standard shipping, express delivery, or in-store pickup at checkout. The system validates location availability and routes orders accordingly. Store associates see pending pickups.
Eight regional storefronts, one catalog
Regional pricing, currencies, languages. Each brand feels distinct. Shared infrastructure. Brand-specific emails, social links, and styling reinforce autonomy.
Campaign management without developers
Landing pages, seasonal collections, promotional popups managed through CMS. Product feeds for Google Shopping and Lengow sync automatically with inventory changes.
The bottom line
If you manage physical inventory, your eCommerce platform isn’t decorative – it’s operational infrastructure.
ERP-first architecture means fewer manual interventions, actual inventory accuracy, and customers who get what they want when they want it. Operations process orders faster without friction.
Frequently Asked Questions
Fashion is inventory-intensive – styles, colors, sizes, seasonal collections. Running ERP and eCommerce independently means manual syncing, overselling, and hidden stock. ERP-first architecture makes the ERP the source of truth with bidirectional sync to every storefront.
Instead of displaying 47 individual SKUs, customers see one product with color swatches and size options. The system manages variant inventory behind the scenes with quantity limits to prevent overselling. Clean display, accurate stock, no SKU explosion.
If your inventory system and eCommerce platform are still separate, we can fix that. Let’s talk about ERP-first architecture.
