Stitched together: how a well-tailored supply chain keeps omnichannel from unravelling

In fashion, siloed inventory is a quiet but damaging threat to margins – and a loud risk to reputation and market share.

Consumers now shop across stores, web shops, marketplaces, and social media as a matter of course. But many fashion brands have yet to build a fashion omnichannel fulfillment and omnichannel supply chain that can support that behaviour without leaking margin.

Omnichannel fulfillment maturity is decided upstream: in how inventory is integrated, how orders are orchestrated, how fulfilment nodes are chosen, and how returns are handled across the network. None of that sits at the customer interface. It sits in the operating model. And so does the solution.

Omnichannel has become a boardroom issue

For years, omnichannel was treated as a commercial or front-end retail initiative – a question of adding channels and faster delivery promises. That framing no longer holds. As Ronald Poort, Head of DSV’s Consumer vertical, puts it: “An omnichannel strategy should not be misunderstood as a commercial or front-end retail initiative, but rather as a supply chain transformation.” The reason is that the economics have hardened at exactly the moment customer expectations have risen. Three pressures are converging:

Ultra-fast marketplaces are going omnichannel

Cross-border players that built their names on weekly drops and near-24-hour delivery are now adding physical storefronts, resetting the market’s baseline for speed and availability.
Returns have moved from exception to baseline reality

High digital penetration has turned reverse flows into a margin issue and a brand-experience issue at once.
Trade and tariff volatility is compressing margins

The restructuring of international trade policy combined with more frequent geopolitical and climate disruptions have pushed landed costs up, leaving less room to absorb the cost of getting inventory in the wrong place.

The question for most brands is no longer whether the omnichannel supply chain matters – it is how to make their supply chain responsive, resilient, and controlled enough to keep up with what the market demands.

The real problem: unintegrated inventory, not missing channels

When omnichannel underperforms, the cause is rarely a missing channel – it’s that each channel runs its own inventory with its own KPIs. That fragmentation produces a predictable set of failures:

Stock in the wrong place

Duplicated safety stock, stockouts in one channel while another sits on ageing inventory, and the slow bleed of product toward markdown.
Channel cannibalisation

A campaign pulls demand into one channel and strands stock in another, so the brand discounts to clear what its own promotion left behind.
Sluggish connectivity

Integrating a new marketplace, carrier, or delivery platform can take weeks of specialised IT work. Brands still running dozens of disconnected warehouse systems get limited visibility and slow reaction times.
Blind spots at the handover

Losing sight of goods at physical handover and purchase-order stages means a brand cannot re-route inventory mid-transit when demand shifts or disruption hits.
Fragility under peaks

Networks designed for steady-state operations fracture under promotional spikes – Black Friday, Singles’ Day – or an unplanned viral surge.

Returns expose the fragmentation most sharply

Nothing tests a fragmented network like a return. And the return burden is not uniform – it varies dramatically by market, which is precisely why a regionally blind, channel-siloed inventory model struggles to cope. This overview of broad estimates illustrates the challenge:

Market	Approximate fashion return rate
Japan	~2–5%
APAC (broadly)	~5–15%
United States	~20–25%
United Kingdom	~30–40%
Germany	up to ~40%
Switzerland	up to ~60%

The spread is the point. A single global returns process cannot serve a network where Japan returns almost nothing, and Switzerland returns more than half of what it ships. Germany sits at the high end largely because of a deep-rooted catalogue-sales culture – what Sara Gerdner Kalle, DSV Chief Commercial Officer for Contract Logistics, describes as consumers who effectively “bring the dressing room home.” When a returned item then takes days to consolidate, grade, and refund, the brand pays twice: once in a slow refund that erodes loyalty, and again when a seasonal item misses its shelf-life window and drops to markdown.

The strategic shift: one integrated inventory

The structural answer is to stop bolting channels onto a legacy base and instead move to one integrated inventory that serves retail, web shops, social media, and marketplaces simultaneously – rather than separate inventories pursuing separate sets of targets.

An integrated setup unlocks the ability to delay allocation for as long as possible. At the point of production, no brand knows for certain where demand will peak – so the goal is to commit a product’s channel and destination as late as the flow allows. That is only achievable when one logistics partner oversees an integrated flow, keeping the brand’s options open until the market shows where the stock should go.

Four capabilities that make omnichannel work

Building a supply chain that can carry this model comes down to four capabilities working as one system:

1. Visibility – integrated inventory, monitored end to end

A brand’s full allocation is managed from one integrated warehouse infrastructure and tracked at PO and SKU level through a control tower and a single visibility platform. That live view is what allows stock to be re-allocated to the highest-performing market in real time, and what closes the handover blind spots.

In today’s world, strong fashion inventory visibility enables brands to synchronize stock across channels and reduce stockouts.

2. Connectivity – integration as a strategic capability

The easier it is to plug in a new channel, carrier or service, the less the network must be redesigned every time the market moves. Consolidating from dozens of warehouse systems toward one means a return dropped in Germany can flow into the same inventory as stock held in Spain.

That connectivity is also what lets a brand offer a genuine breadth of delivery and return options:

Buy-online-pickup-in-store
Ship-from-store
Locker and courier delivery

Plus, a return journey that mirrors the same flexibility in reverse.

For boutique and mall delivery specifically, it means e.g. time-slotted night deliveries, milk runs, and garment-on-hanger racks, so store staff can push stock straight onto the floor.

3. Scalability – scale as the source of flexibility

Volume in omnichannel is rarely linear. Multi-user mega-campuses – such as DSV’s roughly 200,000-square-metre facility in the Netherlands – let a brand flex labour and space by drawing on resources shared across many customers, something no isolated, dedicated site can match.

Automation compounds this: pre-invested systems let throughput scale by extending shift hours with only a handful of extra people, turning peaks from a threat into a routine adjustment. The goal isn’t automation for its own sake: automation, and increasingly AI-sharpened demand forecasting, are what let a network absorb a spike no one saw coming.

Few brands can justify building that capacity alone – which is the case for putting it in the hands of a large-scale logistics partner instead. That same scale applies in transit: a large ocean, truck, and air network means a shipment can switch modes when a market moves or a route is disrupted, without renegotiating capacity from scratch.

4. Circularity – reverse flows in the same inventory

Returns preserve margin only when they move fast and sit in the same inventory as forward stock. Grading at the point of return, reconditioning locally – quality control, steaming, re-ticketing, and increasingly repair – and feeding product back to saleable stock within days rather than weeks keeps value in the network instead of surrendering it to markdown.

Circularity also doesn’t end at resale: what can’t be resold still needs a responsible endpoint, handled in a way that protects both the brand and the environment.

What the payoff looks like

Consolidating to an integrated inventory is not an efficiency footnote. It changes the financial profile of the business:

Sales are no longer lost because the stock sat in the wrong channel:

A single view of inventory means a sale in one channel doesn’t fail because stock is sitting unsold in another.
Full-price margin is protected:

Hitting demand windows before the markdown cliff defends sell-through and lifts Gross Margin Return on Investment, the metric that ultimately decides whether a season paid off.
Working capital is released:

Removing duplicate safety-stock buffers across channels can cut inventory holding meaningfully – an internal benchmark points to a 20–30% reduction – lowering Days of Inventory Outstanding and freeing trapped cash.
Brand equity is protected:

Disciplined multi-modal routing secures on-time execution for drops, launches, and campaigns, so marketing milestones are not undercut by stock that arrives late.
The customer feels it – and comes back:

Fewer out-of-stock notices, faster refunds, and genuine consistency across every channel – that’s the experience that makes a shopper choose the same brand again.

The strategic takeaway

Bringing channels into an integrated inventory served by one logistics partner – and defending the full-price margin as a matter of design – reframes what “good” means. In Ronald Poort’s words:

“Omnichannel maturity is not measured by the number of sales channels that a brand operates. It is measured by how well the supply chain can connect these channels in a way that feels seamless to customers and sustainable for the business.”

Get that connection right, and omnichannel stops being a source of friction and margin leakage. It becomes a source of resilience – the ability to serve any channel, absorb any spike, and recover any return, all from one integrated inventory.

Ultimately, successful fashion omnichannel fulfillment relies on unified inventory management, end-to-end visibility and scalable omnichannel logistics.
