Duty-free retail runs on a paradox: it depends on impulse and convenience, but it operates through some of the most fragmented, high-pressure retail environments in travel. This client is a global travel retail operator running duty-free shop floors across airports and ports in India, Latin America, Europe, and the Middle East, selling exclusively to international travelers who move between multiple currencies, multiple jurisdictions, and a boarding pass with a hard deadline attached.
For this client, that fragmentation had stopped being a background inefficiency and started limiting how the business could grow. Leadership needed more than a better checkout screen at a single counter. They needed visibility across every shop floor location, in every currency; a way to actually understand who their customers were; and a shopping experience that could compete with the convenience travelers expect everywhere else in their journey, all while protecting some of the most sensitive personal and payment data a retail business handles.
The operator's growth was constrained by a broken foundation, not one isolated gap. The existing e-commerce platform was failing outright: inventory and pricing could not be uploaded or changed in real time, and offers could not be updated across locations without a manual, location-by-location process. Every duty-free shop floor set its own pricing, and because duty-free sales serve international travelers only, every one of those prices had to resolve correctly and consistently into multiple currencies.
Beyond the platform itself, four connected gaps compounded the problem. No real-time sales and inventory movement data existed across shop floors at different airports and ports, so leadership had no way to see performance in real time. There was no mechanism to issue promotional coupons to drive incremental buying. There was no centralized customer data to derive buying intent and patterns that could boost sales and guide inventory. And there was no structured stock data to forecast demand during peak hours or to calculate how quickly inventory could move from the nearest allocated warehouse to the shop floor that needed it.
Layered across all of it was a non-negotiable requirement for information security. Duty-free transactions carry highly sensitive personal and payment data across multiple countries and regulatory regimes, and protecting that data had to be engineered into the platform from the start, not added afterward.
Sundew was engaged to design, develop, and deliver a unified platform and connected e-commerce solution for the operator, managing more than 20,000 SKUs and real-time promotional offers by category, by SKU, and by bundle, across every shop floor the business serves. Sundew worked as the digital technology partner within the client's multi-vendor delivery ecosystem, building the platform on Microsoft Azure, a LAMP stack (Linux, Apache, MySQL, PHP), Power BI, and React Native, to bring sales, pricing, inventory, promotions, and customer data under one system rather than many disconnected ones.
Sales, revenue, and inventory data from every shop floor, across airports and ports in India, Latin America, Europe, and the Middle East, were synced into a single, centralized application and connected to the client's ERP and other core enterprise systems. This gave leadership one consolidated, near-real-time view of sales performance and inventory movement across the entire network, replacing a platform that could not even update its own pricing in real time.
The platform gave the business one consistent place to manage pricing, promotions, and stock across every outlet and locality, with real-time offers configurable by category, by SKU, and by bundle. Because duty-free sales serve international travelers exclusively, pricing and checkout were engineered to resolve correctly across multiple currencies at every shop floor, replacing the ad hoc, location-by-location approach that had previously created an inconsistent customer experience.
Customer behavior data by gender, locality, and age group, alongside flight routes and purchase history, was captured and structured within the platform, with Power BI serving as the analytics layer that turned this data into a factual basis for personalization and demand planning rather than assumptions. A personalized recommendation engine used this same data to surface offers relevant to each traveler, instead of the same static catalog for every customer.
Stock data was structured to support analytical forecasting of demand during peak travel hours, and to calculate how quickly inventory could move from the nearest allocated warehouse to the shop floor that needed it. This gave the operations team a way to plan for demand spikes instead of discovering a stockout after it had already cost a sale.
A dedicated preorder website, paired with a React Native mobile experience, let customers with a valid travel ticket and a completed web check-in browse and purchase duty-free products in advance. Orders were then ready for expedited delivery at the time of transit, or at the departure or arrival airport, removing the point-of-sale bottleneck entirely for travelers who preordered, and easing pressure on shop floor billing counters during peak hours.
Sundew built a connected admin section giving the client's teams a single place to manage operations, orders, returns, the e-commerce mobile app, promotional campaigns, and customer surveys, all synced with the client's ERP and other enterprise systems. Management dashboards gave leadership a real-time view for review, while automated alerts flagged stock and inventory issues and triggered promotion go-lives without a manual, location-by-location rollout.
Because duty-free transactions carry highly sensitive personal and payment data across multiple countries and regulatory regimes, information security was engineered into the platform's foundation, with extreme care taken to protect personally identifiable information at every point the platform touched it.
This combination meant the client wasn't just digitizing an existing counter-based sales model; it was creating an entirely new channel for how customers could shop duty-free, ahead of the queue rather than caught inside it, with the security and operational visibility to run that channel at scale.
The unified platform gave the client a single, centralized view of sales, revenue, and customer behavior across a previously fragmented, multi-vendor network spanning airports and ports in four regions, turning scattered operational data into a foundation the business could actually plan around. Structured visibility into customer buying preferences by gender, locality, and age group gave the business a starting point for more targeted offers and locality-specific promotions, replacing guesswork with data.
Most significantly, the preorder experience gave the operator a new way to capture sales that the traditional counter model was losing: customers no longer had to choose between making a purchase and making their flight. Combined with centralized, multi-currency pricing and coupon management across more than 20,000 SKUs, this gave the client a more consistent, differentiated shopping experience across its duty-free channels.
The business saw a sharp overall revenue increase of 11% once the platform was operational, one of the most significant returns on a single technology investment in the brand's history, achieved while maintaining the information security standard the sensitivity of the data demanded.
If your business runs on a multi-vendor or multi-location model, the real cost is rarely visible in any single vendor's numbers; it's hidden in the gap between them. A duty-free counter can look profitable in isolation, while the business as a whole loses sales to queues, misses the customer data needed to personalize offers, cannot forecast stock movement from its own warehouses, and can't see performance across vendors, currencies, or countries in one place.
A unified platform doesn't just centralize reporting. It creates a new channel, like a preorder experience, that a fragmented, counter-only model could never support, and it does so without compromising on the information security a sensitive, multi-country customer base requires. The risk isn't investing in that platform. The risk is continuing to measure a fragmented business one vendor, one currency, and one shop floor at a time.

Frequently Asked Questions
How does a unified platform help a multi-vendor duty free business?
Instead of each vendor tracking sales, revenue, and inventory separately, the platform, built on Microsoft Azure with a Linux, Apache, MySQL, and PHP foundation, syncs this data into a single application. This gives leadership one consolidated view of performance across every vendor and location, replacing fragmented, vendor-by-vendor reporting with a centralized picture of the business.
How does the preorder experience work for travelers?
Customers browse and purchase duty free products in advance through a dedicated preorder website or the React Native mobile experience, then collect their order at the airport, either at arrival or departure, without waiting in the traditional billing queue. This gives time-constrained travelers a way to complete a purchase they might otherwise abandon.
What kind of customer data does the platform capture, and why does it matter?
The platform structures customer buying preference data by gender, locality, and age group, with Power BI turning that structured data into dashboards leadership can act on. This gives the business a factual basis for personalizing offers, planning inventory by location, and designing discounts that reflect actual demand patterns rather than assumptions.
How does centralized pricing and discount management improve the customer experience?
Rather than pricing and coupon management varying by vendor or locality in an ad hoc way, the platform manages these centrally, giving customers a more consistent experience regardless of which outlet or vendor they engage with.
What role did Sundew play in this multi-vendor engagement?
Sundew acted as the digital technology partner within the client's multi-vendor delivery ecosystem, building the unified platform on Azure, React Native, Power BI, and a Linux, Apache, MySQL, and PHP foundation, connecting sales, inventory, pricing, and customer data across vendors, and designing the preorder experience as a new customer-facing channel.
Can this model extend to other retail categories beyond duty free?
The underlying approach, unifying multi-vendor sales data, centralizing pricing, and adding a preorder channel, applies to any high-volume, multi-vendor retail environment where point-of-sale bottlenecks and fragmented data are limiting growth, not only travel retail.
