Luxury and unified commerce: what an OMS like Fluent Commerce changes in the boutique

A client walks into a boutique on Geneva's rue du Rhône, asks for a model she saw the day before on the maison's website, and the sales associate cannot tell her whether it is in stock in Zurich, in Paris or at the warehouse. In luxury, where every piece counts and the in-store experience is the heart of the brand, that moment is expensive. It is exactly the problem an order management system, an OMS, is meant to solve. Here is what it really changes, and why luxury is a special case.

A market that is stabilising and must do better with fewer clients

The Bain-Altagamma study published on 20 November 2025 paints an unforgiving picture. The personal luxury goods market reached 358 billion euros in 2025, down from 364 billion in 2024 and 369 in 2023, a slight contraction at current exchange rates. The client base fell from 400 million in 2022 to around 340 million in 2025, and new client acquisition dropped 5% in a year. "Big spenders" now account for 46 to 47% of the market.

Bain also notes that online channels are holding steady, that monobrand stores are slightly slipping, and that maisons cut 25,000 square metres of retail space in six months, with a clear recommendation: fewer stores, but larger flagships. The sector's EBIT margin, which peaked at 23% in 2012, is expected at 15 to 16% in 2025.

In operational terms: every existing client is worth more, every stock-out costs more, and every boutique must also serve online sales. Inventory can no longer be thought of by channel.

What an OMS actually does

An OMS orchestrates the life cycle of an order across all channels: it consolidates available inventory in real time (warehouses, boutiques, in transit), decides where to ship from, promises a reliable delivery date as early as browsing, and runs store operations (picking, collection, returns). Fluent Commerce, an Australian vendor founded in the mid-2010s and named a Leader in the Forrester Wave for Order Management Systems in Q1 2025, structures its offer in modules: order orchestration, distributed inventory, order promising, store operations and analytics.

The company raised 46 million Australian dollars from Bain Capital on 17 February 2026 to accelerate its AI investments and international expansion. Its references speak to the sector: Prada Group, LVMH, L'Oréal, Balmain, Breitling, as well as JD Sports and Kingfisher. In April 2026, Fnac Darty selected Fluent Order Management as part of the modernisation of its information systems, to gain a consolidated real-time view of inventory and orders across e-commerce, stores and marketplaces.

The Breitling case is the most telling for watchmaking. The maison, with more than 200 boutiques worldwide and e-commerce at around 8% of sales, deployed Fluent in Switzerland in under four months, SAP integration included, then in the United States and Canada. The result announced by the vendor: around 20% more online sales within three months, ship-from-store, click and collect and a choice of delivery date. These figures come from the vendor and should be read as such, but the order of magnitude matches what we observe.

Why luxury is not retail like any other

Applying grocery-style OMS rules to luxury is a classic mistake. Three differences shape the whole configuration.

• Scarcity is intentional. A standard OMS tries to sell inventory as fast as possible from the cheapest location. A luxury maison sometimes wants to reserve pieces for a boutique, a client or an event. Allocation rules must be able to say no to an online order to protect an in-store sale.

• The boutique is the master channel. The sales associate must be able to see network-wide stock, reserve a piece, have it transferred from another boutique, offer home delivery from the store, all without going through customer service. The OMS is first an assisted-selling tool, and only then a logistics tool.

• After-sales and returns are an experience. Returning a watch or a handbag is not a locker drop-off. The OMS must orchestrate authentication, quality control and restocking with piece-level traceability, often down to the serial number.

On top of these constraints comes integration. The ERP (often SAP), the e-commerce platform, the clienteling CRM, the point-of-sale systems and the logistics providers all need to talk to the OMS. Fluent Commerce estimates that integration accounts for half of an OMS project, which matches our experience: configuration takes weeks, integration takes months.

What AI adds, and what it does not replace

Next-generation OMS platforms embed AI layers. Fluent launched an MCP server in late 2025 so that conversational agents can query order status, then in early 2026 a data-driven sourcing logic with A/B testing, to choose the shipping location based on measured results rather than assumptions. For a luxury maison the benefit is real: fewer needless transfers between boutiques, fewer cancellations, a more reliable delivery promise.

But AI does not compensate for wrong stock data. If boutique inventory is not reliable at piece level, no sourcing algorithm will produce a promise you can keep. The first workstream is almost always inventory quality and store operations discipline.

What we take away

In luxury, the OMS is not a logistics project, it is an assisted-selling and scarcity-protection project that is won or lost in the boutique. The maisons that succeed define their allocation rules with retail teams before configuring the tool, treat integration as the real heart of the project, and make their inventory reliable before talking about AI. At 39 Advisory, we work on this kind of unified commerce programme alongside major luxury players, with teams who know both the OMS and the constraints of the brand.
