Bizum on Shopify Plus: Why PrestaShop modules fail (and how native integration saves your sales)

If you have an online store in Spain, you know this: Bizum already accounts for more than 35% of mobile payments in many sectors. Not offering it means losing sales. Having it poorly implemented is a nightmare.

The classic scenario in PrestaShop with Redsys modules is as follows:

• The customer pays with Bizum and the money leaves their account.
• The gateway (Redsys) tries to notify your store, but the module fails or the server has a micro-outage.
• Result: You have the money in the bank, but the order does not exist in the Backoffice .
• Consequence: Furious customer calling because "he has paid and has not received a confirmation email."

As Shopify Plus specialists in Madrid, we've migrated dozens of stores suffering from this "phantom order syndrome." Today, I'll explain why Shopify's payment architecture is infinitely more robust for the Spanish market.

Why does Bizum fail on Legacy platforms?

The technical problem lies in how PrestaShop or Magento handle payment notifications (IPN - Instant Payment Notification). They depend on your server being 100% available at the exact millisecond the bank sends the "OK" signal.

If your hosting has high latency or a firewall blocks the bank's IP address (a common issue with security modules), the order will never be processed. It's a fragile architecture from the 2000s.

Next Generation Payments Integration

At Shopify Plus, we don't install "patched modules." We use official integrations like MONEI or certified gateways that connect via server-to-server APIs.

Advantages of Shopify architecture for Spain:

• Extensible Checkout: Bizum appears as a native option, with its official logo, perfectly integrated into the payment flow (it does not redirect to an ugly external page that breaks trust).
• Automatic Retries: If the connection fails, Shopify has redundant webhooks that ensure that if payment has been received, the order IS CREATED. Every time.
• Automatic Reconciliation: Say goodbye to manually entering data into bank spreadsheets. Your Shopify transaction ID will always match your bank's.

More mobile conversions, fewer abandoned carts

Implementing Bizum in Shopify Plus is not just a technical matter, it is purely financial.

We have measured in our clients that when migrating from a Bizum "with redirection" (classic Redsys) to a modern integration in Shopify:

• Mobile conversion increases by 15-20% .
• Checkout time is reduced to less than 30 seconds.
• Customer service incidents related to "unconfirmed orders" have fallen to zero .

Real Case Study: Young Fashion in Madrid

We worked with a Madrid-based streetwear brand that had a turnover of €2 million, 40% of which came from Bizum payments. On Black Friday, their PrestaShop website crashed, and they lost 10% of paid orders (money received, order not created).

After migrating to Shopify Plus with the MONEI integration for Bizum, they processed 5,000 orders in a single day without a single synchronization error. The license cost was covered solely by the sales recovered that weekend.

Frequently Asked Questions about Bizum on Shopify

Is it necessary to use MONEI to have Bizum on Shopify?

Currently, MONEI is the leading partner offering the smoothest and most certified Bizum integration for Shopify in Spain. While other methods exist (manual gateways), MONEI guarantees a native user experience and transaction security.

How much does Bizum cost on Shopify?

It depends on your payment provider. With MONEI, fees are usually around 1.34% + a fixed fee for cards, but Bizum may have specific terms. The important thing is that, as a Shopify Plus member, you save on the platform's transaction fees (0.15%) if you use certified providers.

Does Bizum work for refunds?

Yes. The integration allows you to process full or partial refunds directly from the Shopify admin panel. The money is returned to the customer's account instantly, just like the original payment.
