The Challenge
In recent years, more and more customers saw the benefits of home grocery delivery, offering consumers great convenience and comfort. To drive further digital growth, PLUS put the emphasis on its omnichannel offering. However, their e-commerce platform began showing its limits. As a monolithic platform, it couldn't handle rapid growth in demand, leading to serious performance issues that negatively affected e-commerce revenue.
In 2021, PLUS decided it was time for a new e-commerce platform, one that would offer stability, better performance and a faster time-to-market. The retailer asked us to help choose and develop the front-end and back-end architecture that could fulfil their ambitions.

Our Approach
1 webshop became 6 projects. OutSystems had never been used as the heart of a composable e-commerce platform for hundreds of thousands of active customers. This called for a highly innovative approach in close collaboration with PLUS.
Using Intershop resulted in thirteen different data systems that were updated once a day, causing a two-day delay. Bringing data into scope significantly expanded the project, resulting in a programme covering six separate projects: the data infrastructure, a retail management portal, the CMS, the e-commerce engine and two separate front-ends.

The Solution & Impact
The unique composable combination of OutSystems, commercetools and Contentful lets PLUS create next-level shopping experiences that are accessible, convenient and distinctive. Together, the three solutions guarantee 99.99% uptime, resolving previous stability issues. New features such as voice or barcode search were added within a single two-week sprint, something that previously would have taken at least two months.
The new webshop went live in February 2024. With annual growth in both market share and online revenue, PLUS can count on a fast ROI.


OutSystems at the heart of a composable webshop
The PLUS case shows what OutSystems can do at enterprise scale: 99.99% uptime, new features live within a single sprint, and automatic scaling during peak demand. Deployed for the first time as the heart of a fully composable e-commerce platform – and it works.
