PrestaShop powers over 250,000 multi-store, multilingual, high-volume projects across the world. Yet, myths persist that keep good-fit merchants away. Some consider it a platform only for small stores; others claim it is inflexible, outdated, or completely unsuitable for B2B. A few of these myths hold a kernel of truth; we won't hide that. But most come from outdated implementations, not from the platform itself.
Understanding where these myths come from matters - dismissing PrestaShop outright could mean ruling out a platform that's actually your best fit.
Myth 1: PrestaShop is only for small stores
This is one of the most repeated myths, and it has little to do with reality. The real issue is that PrestaShop's scalability depends primarily on the quality of the implementation and technical architecture, not on the platform itself. A poorly designed store with a thousand products will perform worse than a well-optimized store with tens of thousands of SKUs. It is a matter of approach and the competence of the team building it, not a limitation of the platform.
PrestaShop supports multi-store, multilingual, multi-currency functionality and large product catalogs. Many mid-sized and large brands across Europe have been running on this platform successfully for years.
That said, at very high volumes - hundreds of thousands of products and very heavy traffic loads - PrestaShop's default architecture may require more work than solutions designed specifically for that scale. For extreme-scale operations, PrestaShop can still be part of the answer, often through a hybrid or headless approach, but that's a deliberate architecture choice, not a default recommendation.
Myth 2: PrestaShop is not flexible enough for complex projects
PrestaShop is often seen as a ready-made store engine: useful when requirements are standard, but supposedly too rigid for complex, non-standard projects. This is an oversimplification.
The important distinction is not whether PrestaShop can be customized. The real question is how deep the customization needs to go. When changes stay close to standard eCommerce processes, PrestaShop usually gives enough room to adapt.
The platform can be extended through modules, hooks, theme customization, integrations, and custom development. For many merchants, this is enough to adapt the store to their sales model without rebuilding the whole system from scratch. A well-planned PrestaShop implementation can support specific checkout rules, pricing logic, customer groups, marketing scenarios, and integrations with external systems.
Myth 3: PrestaShop is slow
Performance problems on PrestaShop do occur, but they are almost never the platform's fault. In the vast majority of cases, a slow store comes down to poor hosting, too many installed modules, lack of database optimization, incorrect cache configuration, or accumulated technical debt from previous years of development.
PrestaShop, properly configured, with good infrastructure and a sensible number of modules, performs well. The problems appear when a store has grown over the years without a considered technical strategy - more modules were added, refactoring was postponed, and performance warnings were ignored. In these conditions, performance issues are a symptom of poor project management, not a weakness of the platform. The diagnosis should start with a technical audit, not with looking for someone to blame in the engine.
It is also worth remembering that performance is not just a matter of code. Infrastructure choices have a significant impact on page load times - shared hosting that works well for a small store with a few hundred products will not be sufficient for a platform handling thousands of orders a day.
What actually moves the needle is that a virtual private server or dedicated server combined with a well-configured caching layer can dramatically change the perceived performance of a store without any changes to the code.
Myth 4: You cannot make a B2B store on PrestaShop
PrestaShop ships with a native B2B mode out of the box: customer groups, individual price lists, and product visibility controls. Many wholesale and distribution companies run on it successfully today.
This myth does have a grain of truth, but it tends to be overstated. Where the problems start is with more advanced processes - company account hierarchies, complex order approval flows, ERP integrations, and customer-specific catalogs. These features require modules or custom development.
For companies with standard B2B models, PrestaShop is often more than sufficient, and for advanced ones, it’s a proven starting point.

Myth 5: PrestaShop is outdated
PrestaShop is sometimes perceived as an older platform that no longer fits modern eCommerce projects. This opinion usually comes from the fact that many PrestaShop stores have been running for years and carry a lot of technical debt. But that says more about the history of individual implementations than about the platform itself.
PrestaShop isn't old; it's mature. And in eCommerce, that's an asset: a proven back office, a large module ecosystem, and years of improvements based on implementation around the world. For many standard B2C and simpler B2B use cases, it remains a practical and proven choice.
Myth 6: Migrating from PrestaShop always means replatforming
If your PrestaShop store is struggling with performance, flexibility, or maintenance costs, replatforming is rarely the first answer - and it's a serious decision that, in many cases, isn't necessary.
A store that runs slowly, is difficult to maintain, or has accumulating technical debt can often be significantly improved through code refactoring, architecture optimization, module consolidation, and infrastructure modernization. Changing platforms makes sense when the business requirements genuinely exceed what PrestaShop can deliver, not as a response to problems that stem from the quality of a previous implementation. Before making a replatforming decision, it is worth commissioning a thorough technical audit that shows what is actually causing the problems.
Replatforming involves not only the cost of implementing a new platform. You also need to account for data migration, rewriting integrations, team training, the transition period, and the risk of errors at launch. In many cases, a well-conducted technical audit and modernization of the existing store cost a fraction of what a platform change would, and the results are felt just as quickly.

Wrapping up
Many of the problems attributed to PrestaShop come down to the quality of the implementation, the architecture, and how the store has been maintained over time. PrestaShop is a mature and well-established platform that works well across a wide range of projects, provided it is properly designed, implemented, and consistently maintained over the years.
A good platform is one that fits the actual needs of the business and is implemented well. PrestaShop, in the hands of an experienced team, can handle complex eCommerce projects. That said, it does not mean it will be the optimal choice for every project, particularly for those with very specific requirements or a headless architecture. The same platform implemented without a considered architecture and development strategy will cause problems regardless of how good its engine is.
The right choice depends on your requirements: For most standard and mid-to-large projects, that's exactly where PrestaShop delivers.
