ReflectivMultilingual B2B e-commerce overhaulmigration from PrestaShop to headless
French leader in adhesive films for 40 years. Complete migration from PrestaShop to a headless e-commerce platform with a professional portal, product configurator and carrier integration.
PrestaShop migration: when a B2B e-commerce hits its limits
Reflectiv has been manufacturing French adhesive films for 40 years. A massive catalogue covering thermal, solar, decorative and safety applications, distributed in over 100 countries and sold to demanding professionals worldwide.
The old PrestaShop site could no longer keep up. Performance was degrading, the purchasing experience for professionals was not up to the brand's positioning, and managing such a large catalogue on an ageing architecture had become a daily obstacle. Jean-Charles Doll needed a platform built to last — one capable of handling the complexity of Reflectiv's business while delivering a premium experience to every visitor, in six different languages.
The challenge was twofold. Technical first: design an architecture capable of supporting an extensive catalogue, thousands of simultaneous professional visitors and complex B2B transactions with client-specific pricing. Editorial second: produce and optimise content in six languages for six different markets, with an SEO strategy tailored to each country. A project of this scale required rigorous organisation and expertise that goes well beyond simple website creation.
Building a headless B2B e-commerce site in 6 languages
The answer to Reflectiv's challenge was a headless architecture combining Next.js on the frontend and Symfony on the backend. A complete migration from PrestaShop, built page by page to guarantee the quality of every component, every interaction and every user journey.
The multilingual e-commerce site was developed in six languages: French, English, Italian, Spanish, German and Arabic. Each language version includes dedicated content writing and market-specific SEO optimisation. This is not automatic translation but genuine editorial work per language, with optimised tags, metadata and URLs market by market.
The professional portal is at the heart of the platform. Reflectiv's clients access a dedicated space with their professional pricing, order history and a checkout optimised for bulk purchasing. Sample ordering is integrated directly into the journey: before placing a final order, any client can order test products from their space.
Connections to the UPS and Geodis carrier APIs allow shipping costs to be calculated in real time and labels to be generated directly from the platform. The Reflectiv team processes orders and requests from a centralised interface without juggling multiple tools.
The film configurator lets every visitor visualise how an adhesive film will look on their surface before ordering. A reassurance tool that answers the first question every professional buyer asks before committing — and mechanically reduces returns and post-purchase enquiries.

Next.js headless architecture for high-performance e-commerce
Moving from PrestaShop to a Next.js + Symfony headless architecture is a complete paradigm shift. Where PrestaShop imposed limits on performance and customisation, headless architecture gives total freedom over the user experience while guaranteeing optimal load times across the entire catalogue. Every page was built to meet Reflectiv's specific needs, with particular attention paid to Core Web Vitals — which directly influence organic search rankings.
The separation between the Next.js frontend and the Symfony backend lets each layer evolve independently. If Reflectiv needs a new client-side feature or an update to the order processing engine on the server side, both can be developed and deployed without affecting the other. An architecture built to last and to support the growth of a player that distributes its products in over 100 countries.
B2B client portal with professional pricing and online ordering
Reflectiv's professional clients have access to a dedicated space after authentication. They find their negotiated pricing, order history, delivery tracking and the ability to order samples before confirming a final order. A journey designed for volume buyers who need certainty before committing.
Managing professional pricing is one of the most complex aspects of the project. Each professional client has specific pricing conditions defined according to their purchase volume and commercial relationship with Reflectiv. The platform handles this complexity transparently: the client sees their prices as soon as they log in, without having to contact a sales rep for a quote.
The sample ordering module is a key differentiator in the professional journey. Before ordering full rolls, an installer or distributor can order samples directly from their client space. This process, previously handled by email or phone, is now fully digitalised and managed by the Reflectiv team from the centralised management interface.
Multilingual e-commerce site in 6 languages with per-market SEO
Six languages, six markets, six content strategies. Each language version of the site received dedicated writing and SEO optimisation. Content was not simply translated but adapted to the usage patterns and specific queries of each market. The site is available in French, English, Italian, Spanish, German and Arabic, with URLs, hreflang tags and metadata optimised for each language.
The Arabic version deserves special mention. Beyond translation, it requires a full right-to-left interface adaptation. Every component of the site was designed to work in both reading directions, with no compromise on user experience or performance.
UPS and Geodis carrier integration for logistics management
Connecting to the UPS and Geodis APIs automates logistics management. Shipping costs are calculated in real time based on weight, volume and destination. Labels are generated directly from the platform. The Reflectiv team processes orders and sample requests from a centralised interface, with no breaks in the processing flow.
This integration eliminates manual data entry errors and reduces the processing time for each order. For a player distributing to over 100 countries, logistical reliability is as important as product quality. The platform ensures every order is handled with the right carriers, the right lead times and the right shipping rates for each destination.
Technical SEO optimisation and multilingual copywriting
Natural search engine optimisation for a multilingual e-commerce site is a project in its own right. For Reflectiv, the SEO work covered two complementary dimensions. Technical first: URL architecture, hreflang tags to indicate to Google the language of each page, Core Web Vitals optimisation, structured data for product pages and the multilingual sitemap. Editorial second: content writing and optimisation for each language, with keywords adapted to the specific queries of each market.

Why migrate from PrestaShop to a headless architecture?
PrestaShop is a suitable solution for starting an e-commerce, but it reaches its limits on complex catalogues with advanced B2B requirements. A Next.js + Symfony headless architecture offers total freedom over the user experience, significantly better performance and the ability to scale without the constraints of a standard CMS. It is the preferred solution for B2B e-commerce sites with large catalogues and high customisation needs.
How do you create a multilingual e-commerce site optimised for SEO?
Creating a multilingual e-commerce site optimised for organic search requires much more than simple translation. For Reflectiv, each language version received dedicated editorial work with an SEO strategy tailored to the specific queries of each market. Hreflang tags, metadata, URLs and content were optimised language by language to maximise visibility in each target market.
How does a B2B client portal work on an e-commerce site?
The Reflectiv professional portal is accessible after authentication. Each client finds their negotiated pricing, order history and the ability to order samples before confirming a final order. The B2B checkout was designed specifically for volume buyers who need reassurance before purchasing.
How do you integrate carrier APIs into an e-commerce site?
The Reflectiv site is connected to the UPS and Geodis carrier APIs. Shipping costs are calculated in real time based on weight, volume and destination. Labels are generated directly from the platform without manual intervention. This type of integration is available on Infinity plans with the Dev hub.
What is headless architecture for an e-commerce site?
Headless architecture separates the frontend — the visible part of the site — from the backend — the engine that manages data and orders. For Reflectiv, the frontend is built with Next.js and the backend with Symfony. This separation delivers significantly better performance than a traditional CMS and total freedom over the user experience. Each part can evolve independently without affecting the other.
How do you manage a site in Arabic with a right-to-left interface?
The Arabic version of the Reflectiv site requires a complete right-to-left interface adaptation. Every component of the site was designed to work in both reading directions. This is specific technical work that goes far beyond simple translation and requires frontend multilingual development expertise.
Is the e-commerce site mobile-friendly?
Yes. The Reflectiv site is fully responsive. The professional portal, product configurator and checkout all work on every device. This is a non-negotiable criterion on all Synerium projects.
Can the site evolve after delivery?
Yes. With an Infinity plan, the site continues to evolve every month. New features, new product pages, technical optimisations, checkout adjustments. A B2B e-commerce site is never set in stone.
