If you're here, it's because you're facing the classic European ecommerce decision: Do I keep struggling with PrestaShop or switch to Shopify?

On paper, the decision seems simple: "PrestaShop is free and Shopify has a monthly fee." But in the real world, "free" doesn't exist.

In this comprehensive analysis, we'll compare both platforms not based on what their websites claim, but on what we observe daily while auditing migrations. We'll discuss Total Cost of Ownership (TCO) , technical debt, Black Friday security, and real-world scalability.

1. The Myth of "Free Software": Analysis of Real Costs

PrestaShop is open source (free to download), but expensive to maintain. Shopify is SaaS (pay-as-you-go). Let's look at the real numbers for a store that generates €500,000 in revenue per year.

Financial conclusion: PrestaShop has a very high hidden cost for infrastructure and technical labor. Shopify turns variable and unpredictable costs into a fixed monthly cost.

2. Security: Who's watching your store at 3 am?

In ecommerce, security is synonymous with money.

PrestaShop: "You are the head of security"

If you use PrestaShop, security is 100% your responsibility. You must:

• Update the server's PHP version.
• Patching security holes in third-party modules.
• Configure the Firewall to prevent DDoS attacks.
• Renew SSL certificates.

If you get hacked (and PrestaShop is a frequent target), you're on your own.

Shopify: "Fort Knox included"

Shopify is a closed, bank-grade platform (PCI DSS Level 1). They have a team of hundreds of engineers monitoring the network 24/7. You can't "break" Shopify even if you wanted to. Backups are automatic and redundant.

3. Performance (WPO) and Technical SEO

Google loves speed. And here's a key architectural difference.

The cache trap in PrestaShop

PrestaShop can be fast, yes. But it requires expert server setup (Varnish, Memcached, CDN). As you add modules and products, the MySQL database becomes fragmented and queries slow down. It's common to see PrestaShop stores take 4-5 seconds to load.

Shopify's Global CDN

Shopify hosts your store on Cloudflare's global CDN (Content Delivery Network). This means your store loads just as quickly in Madrid, Mexico City, or Tokyo, because the content is served from a server close to the user. It also automatically optimizes images to WebP format.

4. Flexibility: Code vs No-Code

PrestaShop (Total Flexibility): With access to the source code, you can modify anything you want. It's ideal if you have highly specific needs (e.g., a complex industrial product configurator that connects to a legacy ERP).

Shopify (Agile Flexibility): With Shopify 2.0 and Metafields, you can customize almost everything without touching any code. For extra features, the App Store is vastly superior to the PrestaShop Addons Marketplace. Shopify apps install with one click and, most importantly, uninstall cleanly without leaving any database clutter.

Frequently Asked Questions about Migration

Will I lose my SEO if I migrate from PrestaShop to Shopify?

It's the biggest fear, but there's a solution. If a professional migration is carried out with a comprehensive 301 Redirect plan, traffic is maintained. At Migraciones.io, we specialize in "SEO Zero Loss" migrations.

Can I migrate my clients and passwords?

We migrate customers, addresses, and historical orders. Passwords cannot be migrated for security reasons (they are encrypted). The standard solution is to send an "Account Activation" campaign when launching the new store.

Does Shopify charge a commission on sales?

If you use Shopify Payments (their native gateway), the extra transaction fee is 0%. You only pay the card fee (which is very competitive). If you use external gateways in PrestaShop (Redsys, PayPal), you're already paying those fees.
