We moved PCDIGA, Portugal's largest online electronics retailer, from Magento to Saleor without a big bang: a phased migration to a headless, composable architecture, integrated with SAP S/4HANA, with requests up to 99% faster and zero unplanned downtime.
Since 2004, PCDIGA has been the go‑to destination for tech in Portugal. Hardware, gaming, consumer electronics: a catalogue of more than 70,000 products and a demanding audience that expects a fast, modern shopping experience that's always available.
Skrey has worked with PCDIGA for years. For a long time, we pushed Magento to its limits to deliver a market‑leading experience. But there came a point where the problem was no longer what we were building: it was the platform.
The challenge
Magento had served PCDIGA well, but it had become a brake on growth: Very high infrastructure costs that grew with traffic. A monolithic, plugin‑based architecture, where every upgrade meant reviewing, rewriting and retesting modules. A major upgrade could tie up two developers for a whole month. Instability when it mattered most. Stuck indexes, cache corruption and timeouts added up to around an hour of unplanned downtime a month, and every Black Friday was a tense affair. A catalogue that was heavy to manage. With more than 70,000 products, changing a single attribute could trigger hours of full catalogue reindexing. Ambitions the platform wouldn't allow, such as a fully custom PC configurator.
The solution
We proposed a change of philosophy to PCDIGA: move away from a platform that tries to do everything, and use the best tool for each job. We chose Saleor, a headless, composable platform, and designed a migration that wouldn't put the business at risk.
A phased migration, no big bang. Instead of switching everything at once, we followed a phased approach known as the strangler pattern. We replaced Magento's modules with independent services, one by one, and each feature only moved to Saleor after thorough testing. PCDIGA changed platforms with minimal, always‑planned downtime, without interrupting sales.
A best‑of‑breed architecture
Each area of the business now has the right tool: Saleor for commerce, Strapi for content, Typesense for search, Temporal for process orchestration, plus integrations with Klarna, Sequra, Trustpilot and Citrus Ad. The marketing team gained the freedom to build landing pages without wrestling with code, and each team works with the tools it prefers.
SAP S/4HANA integration. We integrated the new platform with SAP S/4HANA, which remains at the heart of product and order management. The PCDIGA team needed no new training and didn't have to change how it works: operations kept running in SAP, without disruption.
11 custom apps, no plugins
Saleor's extensibility model makes it possible to build apps that are fully isolated from the core, communicating only through GraphQL and webhooks. We built 11 custom apps for PCDIGA, with up to six in development at the same time, with no conflicts between them or with the platform's core. This foundation is what made innovations like the PC configurator possible.
Cloud, with scale and predictability. We initially planned to self‑host, but after testing Saleor Cloud we recommended it to PCDIGA for its security, scalability and predictable cost.
How we worked. As PCDIGA's long‑standing partner, we knew the platform, the business and its limitations inside out. We assessed alternatives, chose an architecture we could trust for the long term and planned the migration in phases, so every step was safe. In parallel, we kept delivering new features.
Results
PCDIGA now has a platform that keeps pace with its ambition. Faster, more stable and with predictable costs, ready to scale traffic without infrastructure costs spiralling. The team stopped spending time maintaining the platform and started using it to create new customer experiences.
Portugal's largest online electronics retailer is no longer held back by technology; it now uses it as an advantage.
