Subdued: E-Commerce Expansion Across Asia
Subdued: Powering Asian E-Commerce Expansion Across Hong Kong & South Korea
Client: Subdued
Industry: Fashion & Lifestyle Retail (DTC / E-Commerce)
Services Provided: Shopify development, Custom API integration, PIM & OMS implementation, 3PL & warehouse integration, Multi-market e-commerce strategy
Project Objective: Launch and operationalise localised Shopify storefronts for Hong Kong and South Korea, fully integrated with regional 3PL providers, a centralised product information system, and a custom order management interface - enabling Subdued to scale into Asia without losing operational control.
The Challenge
Subdued is a fashion brand with a strong identity and an established presence in Europe. Breaking into Asian markets - particularly Hong Kong and South Korea - presented a different kind of complexity.
This wasn't simply a matter of translating a website. Each market came with its own challenge:
Fulfillment infrastructure — different warehouse partners, different last-mile logistics providers, and incompatible data formats across each 3PL
Product data requirements — localised sizing, language variants, region-specific SKUs, and catalogue management needs that the existing system couldn't handle at scale
Order flow complexity — a single customer journey touching multiple systems: storefront, OMS, warehouse, and payment gateway, all of which had to work seamlessly across two markets simultaneously
No existing Asian tech stack — Subdued's European infrastructure wasn't designed with APAC in mind, meaning the build required both greenfield development and careful integration with what already existed
The risk was real: a rushed build could mean overselling, fulfilment failures, or a customer experience that undermined the brand before it had a chance to establish itself in the region.
Our Strategic Approach
Foundcoo designed a multi-layer infrastructure to support Subdued's Asia expansion — built for reliability, scalability, and operational clarity.
Localized Shopify Storefronts
We built two distinct storefronts — hk.subdued.com and kr.subdued.com — each tailored to its market. This included localised languages, regional currency and payment methods, market-specific navigation and content, and compliance with local e-commerce standards. Both storefronts were built on Shopify with performance and conversion in mind, maintaining Subdued's brand aesthetic while adapting the experience for local audiences.
Custom API Layer
Rather than forcing incompatible systems to talk to each other with off-the-shelf connectors, we built a custom API integration layer that served as the operational backbone of the entire setup. This layer:
Managed real-time data exchange between the Shopify storefronts, the OMS, and each regional 3PL
Handled order routing logic — ensuring each order was directed to the right warehouse, in the right format, at the right time
Normalised data structures across systems with different schemas, preventing errors caused by format mismatches
Enabled bi-directional sync for inventory, order status updates, and fulfilment confirmations
Custom PIM Interface
Product information management was a significant operational pain point. We built a customised PIM interface that allowed Subdued's team to manage product data centrally — including localised descriptions, regional SKU variants, image assets, sizing guides, and catalogue rules — and push updates across both storefronts from a single source of truth.
With 1,200 SKUs per store, each carrying multiple size and colour variants, manual management was never an option. Updates made in the PIM triggered automatic propagation to Shopify via metaobject creation and sync, keeping product data accurate and consistent across both markets without any manual intervention. This removed duplication overhead and dramatically reduced the risk of catalogue inconsistencies at scale.
Custom OMS Interface
We developed a tailored Order Management System interface designed for how Subdued's operations team actually works. This gave them full visibility across both markets — order status, fulfilment progress, exceptions and escalations — without needing to log into multiple platforms or reconcile data manually. The OMS acted as the central command layer for all post-purchase activity across HK and KR.
3PL & Warehouse Integration
Each market used a different logistics partner. We integrated both 3PLs into the unified tech stack — handling authentication, data formatting, dispatch triggers, tracking updates, and exception management specific to each provider. This meant Subdued's operations team managed everything from one place, regardless of which warehouse was fulfilling the order.
Technical Capabilities Demonstrated
This project required a full-stack approach across several disciplines working in parallel:
Shopify custom development — multi-market storefront architecture, theme customisation, localisation
API engineering — custom middleware, webhook management, real-time sync between heterogeneous systems
PIM build — centralised product data management with multi-market publish logic
OMS customisation — operational dashboard, order routing rules, exception handling workflows
3PL integration — multi-provider logistics connectivity with format normalisation and status sync
Data architecture — canonical data models to prevent conflicts between systems with different schemas
Results & Impact
The dual-market launch went live on schedule, with full operational integration from day one.
600+ orders processed in month one — both storefronts live and transacting from launch day, with all orders routed, fulfilled, and confirmed without manual intervention
Two markets live simultaneously — Hong Kong and South Korea storefronts launched with localised experiences and full backend connectivity
Zero fulfillment system failures at launch — the custom API layer handled order routing reliably from the first transaction
Single operational view — Subdued's team managed both markets through a unified OMS, eliminating the need to juggle multiple platforms
2,400 SKUs managed across both stores — 1,200 per market, each with multiple size and colour variants, all maintained through the centralised PIM and automatically synced to Shopify metaobjects without manual duplication
3PL parity — despite using different logistics partners per market, the operational experience was identical from the brand's side
Brand integrity maintained — both storefronts reflected Subdued's aesthetic and positioning, localised without dilution
Why It Worked
Expanding into Asia isn't just a marketing problem — it's an infrastructure problem. Most fashion brands underestimate the operational complexity of multi-market e-commerce until they're already in it: mismatched data formats, broken order flows, and fulfillment failures that damage the brand before it's had the chance to build trust locally.
We approached this as an engineering and operations challenge first, not a website build. The custom API layer, unified OMS, and centralized PIM were designed to give Subdued operational control from day one — so the brand could focus on growth, not firefighting.
Takeaway for Your Brand
If you're a fashion or lifestyle brand planning to expand into Asian markets, the technical complexity is real — but it's manageable with the right architecture. The key is building systems that scale, not workarounds that create technical debt.
Foundcoo specializes in exactly this: multi-market Shopify builds with the integrations, custom interfaces, and operational infrastructure that make expansion actually work.
