Redsys vs. Stripe: Which Payment Gateway Should You Choose for Your Website in Spain?
Compare Redsys and Stripe to choose the best payment gateway for your business in Spain: fees, integration, trust, and when to use each one.
If you're building an online store or adding payments to your website in Spain, you'll eventually face the same question: Redsys or Stripe?
Both are solid options, but they serve very different contexts. In this article we break down the real differences so you can make the right call — without losing sales or overcomplicating your tech stack.
What is Redsys?
Redsys is the payment platform behind Spain's major banks (Santander, BBVA, CaixaBank, Sabadell…). That payment form with your bank's logo you see on Spanish websites? Almost always Redsys under the hood.
How it works: merchants sign up for a virtual POS (TPV virtual) directly with their bank, which then grants access to the Redsys gateway.
What is Stripe?
Stripe is an international payment gateway founded in Silicon Valley, available in over 40 countries. Unlike Redsys, you don't need to visit a bank: sign up online, verify your identity, and you can start accepting payments in minutes.
How it works: Stripe acts as an intermediary between your website, the buyer's bank, and yours — all managed through their platform and API.
Head-to-Head Comparison: Redsys vs. Stripe
Fees
| Concept | Redsys | Stripe |
|---|---|---|
| Setup cost | Depends on bank (€0 – €100+) | Free |
| Transaction fee | Negotiated with bank (~0.8% – 1.5%) | 1.5% + €0.25 (EU cards) |
| Monthly fee | Possible depending on bank | None |
| International cards | Extra cost | Included (slight surcharge) |
Note: Redsys fees vary significantly depending on your bank and sales volume. If you have a strong banking relationship, you can negotiate very competitive terms.
Ease of Integration
Redsys has technical documentation that, honestly, isn't great. Integration requires more work, manual test environment setup, and certificate management. Without an experienced developer, it can be frustrating.
Stripe is the opposite: excellent documentation, libraries for every language, sandbox environment ready in seconds, and an API that's a pleasure to work with. It's the go-to choice for modern development teams.
Buyer Trust in Spain
Redsys has the edge here. Many Spanish buyers — especially older demographics — recognize and trust their bank's payment form more than a generic Stripe screen. That visual recognition can reduce cart abandonment in certain sectors.
Dispute and Fraud Handling
Redsys delegates dispute management to the bank, which can be slow but sometimes favors merchants in the Spanish context.
Stripe has its own dispute management system — fast, well-documented, and with powerful built-in fraud tools (Stripe Radar).
Recurring Payments and Subscriptions
Stripe wins clearly here. Stripe Billing makes it easy to manage subscriptions, free trials, upgrades, and downgrades with minimal code. It's the standard choice for any SaaS or subscription-based business model.
Redsys supports recurring payments, but the implementation is more complex and limited.
When to Choose Redsys
- Your audience is mainly Spanish and tends to be more traditional
- Your bank already offers competitive terms and you have solid sales volume
- You sell physical products with a high average ticket (negotiated fees pay off)
- You have a developer who knows the integration
When to Choose Stripe
- You're starting out and want to set up payments quickly without bank dependencies
- Your product is digital, SaaS, or subscription-based
- You sell to international customers
- You want a modern, well-documented API to scale with
- You use tools like WooCommerce, Next.js, or any modern tech stack
Can You Use Both?
Yes — and in some cases it makes sense. Some businesses use Stripe as the primary method and offer Redsys as an alternative for customers who prefer paying through their bank. This can increase conversion rates by giving buyers more options.
Conclusion
There's no single right answer. If you're starting out or building a digital product, Stripe is almost always the better choice for its ease of use, speed, and technical power. If you run an established physical business with a strong banking relationship and sell mainly to Spanish customers, Redsys may be cheaper and generate more trust.
The key is not to choose by default. Analyze your case, your audience, and your tech stack before deciding.
