The solution

wwwarcelona developed an internal mobile application that revolutionizes the inventory process in TOUS stores. The system is as simple as it is effective: the employee opens the app, scans the barcode of each piece on the counter with the mobile camera, and the system automatically updates the stock in the central database. A process that previously required hours of manual work, prone to errors and on a weekly or monthly basis, is now completed in five minutes and can be done daily. The result: accurate inventories, in real time, in the brand’s more than 200 stores around the world.

Definition of the challenge

TOUS is a jewelry and accessories brand with a presence in hundreds of stores around the world. In 2020, the company faced a major operational challenge: stock control at store counters was done completely manually. Employees counted piece by piece, noted units and updated systems in a slow, costly process with a significant margin of error. Despite having a good in-house technical team, it did not have the necessary specialization to develop a mobile solution that solved the problem in an agile and scalable way.

Product strategy and functional design

The design of the app has been conceived for professional use in an in-store environment: clean, minimalist interface and optimized for speed. With few screens and direct navigation, any employee can learn how to use it in minutes. The goal was not to impress visually, but to eliminate friction – to make scanning, counting and stock validation as fast and intuitive as possible.

Technical Architecture, Integrations, and Performance

The application has been developed with React Native, allowing for rapid deployment on both iOS and Android devices without the need to maintain two separate base codes. The barcode scanning system takes advantage of the device’s native camera capabilities, integrated with specialized libraries to ensure fast and reliable reading even in variable lighting conditions typical of a store environment. The connection to the TOUS backend is made via REST API, allowing a clean and secure integration with the customer’s existing systems.

The application integrates directly with TOS’ internal product database via API, so that each barcode scan queries the catalog in real time and updates the counter inventory on the spot. The system manages thousands of product references – jewelry, accessories, seasonal collections – ensuring that stock data is always accurate and up-to-date. The architecture allows partial offline use in case of limited connection in the store, synchronizing the data in the background when the connection is restored.

Market launch and validation

As it was an internal tool, there was no external marketing campaign. The dissemination was internal: training for store teams, documentation of use and support in the progressive deployment in the more than 200 stores. Adoption was rapid thanks to the simplicity of the interface and the drastic reduction in the time spent on inventory.

We went from hours of manual work to five minutes per store. A real and immediate transformation.

The team

The project was covered by a multidisciplinary team from wwwarcelona: process analysis, interface design, development of the mobile app and integration with TOUS’ internal systems. Once the solution was delivered, we trained the client’s internal technical team so that they could maintain and evolve the project autonomously, with timely support from us when necessary.

Clients who have already walked the journey with us.

Real experiences of customers who have entrusted us with their digital products.

The wwwarcelona team accepted and overcame the difficult challenge of redoing and improving our app initially developed by another agency. A job that many other agencies did not see themselves able to do.
