Most content comparing Shopify and PrestaShop is written for merchants who’ve already decided to migrate and just need a checklist. This isn’t that. If you’re still at the decision stage, genuinely weighing up whether to stay on PrestaShop, upgrade your PrestaShop setup, or move to Shopify, the comparison looks different, because the real trade-off isn’t features on a spec sheet. It’s SaaS versus self-hosted, and everything that decision drags with it.
The Fundamental Difference: Hosted SaaS vs Self-Hosted Open Source
This is the decision underneath every other comparison point.
PrestaShop is open-source, self-hosted ecommerce software. You (or your developer/agency) are responsible for hosting, server maintenance, security patching, PCI compliance infrastructure, and keeping the core platform and any modules updated. In exchange, you get full source-code-level control and no platform transaction fees baked into the core software itself.
Shopify is a fully hosted SaaS platform. Shopify handles hosting, security patching, PCI compliance, uptime and infrastructure scaling as part of your subscription. You trade some low-level control for the fact that none of that infrastructure work is your problem.
Neither is objectively “better”, it depends entirely on whether your business wants to own that infrastructure responsibility or pay to outsource it.
Cost Comparison: Where the Real Costs Actually Sit
This is where a lot of PrestaShop vs Shopify comparisons get misleading, because they compare Shopify’s subscription fee against PrestaShop’s “free” core software, which isn’t a fair comparison of total cost of ownership.
PrestaShop’s real costs typically include: hosting (which needs to scale with traffic and be properly secured), a developer or agency for setup, ongoing maintenance and security patching, and often several paid modules for functionality that comes standard in Shopify (advanced shipping rules, abandoned cart recovery, certain payment options). The core software licence being free doesn’t mean the total cost is low, it shifts cost from subscription fees to hosting and developer time.
Shopify’s costs are more predictable and bundled: a monthly subscription (which scales with plan tier and, for larger merchants, Shopify Plus), plus transaction fees if you don’t use Shopify Payments, plus paid apps for anything beyond native functionality. The trade-off is a more predictable, if less flexible, cost structure.
Rather than quoting specific current prices for either platform here, both change their pricing structures periodically, the practical exercise is to build out your actual total cost of ownership for each: hosting + maintenance + modules + developer time for PrestaShop, versus subscription + apps + transaction fees for Shopify, based on your specific catalogue size and feature needs.
Feature and Flexibility Comparison
Customisation depth. PrestaShop, as self-hosted open source, technically allows deeper core-level customisation since you have direct access to the codebase. Shopify’s customisation happens through its Liquid templating language, theme architecture, and app/API ecosystem, extensive, but working within Shopify’s platform constraints rather than modifying core commerce logic directly. For most merchants, Shopify’s app and API ecosystem covers the functionality gap; for a small number of highly specific technical requirements, PrestaShop’s core-level access matters more.
App and module ecosystem. Shopify’s App Store is significantly larger and more actively maintained than PrestaShop’s module marketplace, which matters practically, better app support generally means faster problem-solving and fewer compatibility issues when you need new functionality.
Checkout. Shopify’s checkout is a major differentiator, it’s built, hosted and continuously optimised by Shopify itself, with strong native conversion features. PrestaShop’s checkout is more customisable at a code level but the optimisation work (speed, conversion, mobile UX) is entirely on you or your developer to build and maintain.
Multi-store and B2B. Both platforms support these, but the setup and maintenance burden differs, Shopify’s Markets and B2B features are increasingly native, where PrestaShop typically requires more manual configuration or modules to achieve similar outcomes.
Support and Maintenance Reality
This is genuinely one of the biggest practical differences, and it’s often underweighted in comparisons. With PrestaShop, when something breaks, a module conflict, a server issue, a security vulnerability in an outdated plugin, resolving it is your responsibility or your developer’s, on your timeline. With Shopify, core platform issues (uptime, security, PCI compliance) are Shopify’s responsibility, and support is available directly from Shopify alongside your agency relationship for anything store-specific.
If your business doesn’t have in-house technical capacity, or doesn’t want an ongoing dependency on a specific developer’s availability, this alone is often the deciding factor toward Shopify.
Security and Compliance: An Often-Overlooked Difference
This deserves its own callout because it’s frequently underweighted in platform comparisons, yet it’s one of the more consequential practical differences.
On a self-hosted PrestaShop store, PCI DSS compliance, server-level security patching, and protecting against common web vulnerabilities are all responsibilities that sit with you or your hosting/development provider. This isn’t a one-off task, it’s ongoing, and a missed patch or an outdated module with a known vulnerability is a genuine risk vector, not a hypothetical one.
On Shopify, PCI compliance and core platform security are handled as part of the hosted service, Shopify’s infrastructure team manages this at a scale and consistency that’s very difficult for an individual merchant’s hosting setup to match. This doesn’t mean a Shopify store can’t have security issues (poorly vetted apps, weak admin passwords, and misconfigured integrations are all still real risks) but the baseline platform-level burden is substantially lower.
For merchants without dedicated in-house security or DevOps capability, this alone is often a meaningful factor in the total risk profile of each platform, separate from the cost comparison discussed above.
When PrestaShop Genuinely Makes More Sense
In fairness, PrestaShop isn’t strictly worse, it can be the right call when:
- You have specific, deep customisation requirements that fall outside Shopify’s app/API model
- You have (or plan to build) in-house technical resourcing to manage hosting and maintenance properly
- Your business operates in a region or with a payment/tax requirement PrestaShop’s ecosystem is genuinely stronger for
- You’ve already invested heavily in custom PrestaShop modules that would be expensive to rebuild
Performance and Scalability Under Real Traffic
This is worth calling out separately because it’s a genuinely different experience between the two platforms under load.
Shopify’s infrastructure is built to absorb significant traffic spikes, a sale event, a viral moment, a major marketing push, without the merchant needing to plan server capacity in advance. This is part of what you’re paying the subscription for. A self-hosted PrestaShop store’s ability to handle the same spike depends entirely on how well the hosting environment has been provisioned and configured, and under-provisioned hosting is a common, painful failure point during exactly the moments, big sales, peak season, when a store can least afford downtime.
This doesn’t mean PrestaShop can’t scale, with the right hosting setup and technical management, it can handle serious traffic. But that scalability has to be actively engineered and maintained by you or your provider, rather than being a built-in property of the platform the way it is with Shopify.
When It’s Worth Migrating to Shopify
The pattern we see most often among merchants who move from PrestaShop to Shopify: they’re spending more time and money on hosting, maintenance and module conflicts than the business can justify, checkout conversion is underperforming compared to what a modern hosted checkout delivers, or they simply don’t have, and don’t want to build, the in-house technical capacity self-hosting demands long-term.
A Practical Decision Framework
- [ ] Calculate genuine total cost of ownership on both platforms for your actual catalogue and traffic
- [ ] List the specific customisations you rely on today, and confirm whether they’re achievable via Shopify’s app/API ecosystem
- [ ] Assess your in-house technical capacity honestly, who currently handles hosting, security and module updates?
- [ ] Compare checkout conversion potential, since this is one of Shopify’s clearest structural advantages
- [ ] Factor in migration cost and downtime risk against the ongoing cost difference, not just sticker price

FAQ
Is Shopify more expensive than PrestaShop?
Not necessarily, once you account for PrestaShop’s hosting, maintenance, developer and module costs. PrestaShop’s core software is free, but total cost of ownership is often comparable to or higher than Shopify’s subscription model once those costs are included.
Can I customise a Shopify store as much as a PrestaShop store?
For most standard and even fairly advanced ecommerce requirements, yes, through Shopify’s theme architecture, Liquid, apps and API. For deep core-level commerce logic changes, PrestaShop’s open-source access does offer more direct control.
Does Shopify or PrestaShop have better checkout conversion?
Shopify’s checkout is generally considered stronger out of the box, since it’s continuously optimised and hosted by Shopify itself. PrestaShop’s checkout can be customised extensively, but achieving the same level of optimisation requires deliberate ongoing development work.
Is migrating from PrestaShop to Shopify difficult?
It’s a genuine project, product, customer and order data migration, theme rebuild, and redirect mapping all need proper planning, but it’s a well-understood migration path with established processes, not an unusual or high-risk move.
Who should stay on PrestaShop instead of migrating?
Merchants with deep, specific core-level customisation needs, established in-house technical resourcing, and no material pain around hosting, maintenance or checkout performance generally have less reason to migrate.
