Stripe vs PayPal vs Bizum: Which is the best payment gateway to receive money today?

Post actualizado el día September 27, 2026 by DeiviSanzPlay

The era of relying exclusively on PayPal is over. Fees exceeding 3.4%, the risk of frozen funds for up to 180 days, and abandonment rates of 26% force businesses to look for smarter alternatives.

For years, PayPal was the undisputed standard for online commerce, generating immediate trust among customers. However, its current model presents significantly higher costs than modern alternatives and operational risks that can paralyze your business like Redsys.

This article is not just another list of alternatives. It is a strategic guide that analyzes everything from local gateways to those that will dominate 2026: from AI-driven “Agentic Commerce” to monthly fees, the difference exceeds €1,000 per month.

• Liquidity risk: PayPal can freeze funds for up to 180 days if it detects patterns it considers suspicious, creating sudden and serious cash flow problems.

Practical setup: In WooCommerce, use the “Unified Gateway” module from Redsys. The process usually takes 2-4 hours and includes configuration for cards and Bizum in the same flow.

2. Stripe: The global platform for international expansion

When your market transcends borders, Stripe offers the perfect balance between functionality and simplicity:

• Architecture for subscriptions: Its native subscription management system avoids complex integrations with third parties like Chargebee or Recurly.
• Multi-currency and local methods: Accepts payments in dozens of currencies and methods such as Apple Pay, Google Pay, and regional options.
• AI-powered fraud prevention: Uses machine learning to reduce false positives while protecting your business.

For digital businesses: Consider solutions like FastSpring that act as a “Merchant of Record” (MoR), automatically managing international taxes, legal compliance, and fraud prevention through partners like Sift. Mailbird achieved growth of over 100% after migrating to this model.

3. Specialized solutions by region and vertical

• Mercado Pago for LATAM: If you sell in Latin America, it is essential to accept cash payments. Mercado Pago integrates OXXO (Mexico), PagoFacil (Argentina), and other methods that cover the unbanked population.
• Gateways for influencers: Platforms like HypeAuditor and Aspire automate payments to content creators, managing invoices, multiple currencies, and automatic reminders.
• BNPL (Buy Now, Pay Later): It is not a gateway per se, but integrating installment payment options can increase the average order value especially for high-value products.

2026 Trends: How to prepare your business for the future

Agentic Commerce: When AI shops for your customers

“Agentic Commerce” will be a reality in 2026, with AI assistants making autonomous transactions on behalf of users. Google already launched “Buy for me” in 2025, and Amazon observed that users of its Rufus assistant are 60% more likely to complete a purchase.

Implementation strategy:

• Ensure your gateway supports emerging protocols such as OpenAI’s Agentic Commerce Protocol (ACP) or Google’s Universal Commerce Protocol (UCP).
• Prepare structured product descriptions that AI agents can easily interpret.
• Implement payment tokenization for secure AI-initiated transactions, leveraging services like Visa Intelligence Commerce (VIC) or Mastercard Agent Pay (MAP).

Mass tokenization and invisible payments

By 2030, Mastercard will require full tokenization for ecommerce payments in Europe. This technology, which replaces sensitive data with unique tokens, increases authorization rates by up to 5%.

Practical benefits:

• Fraud reduction: Tokenized transactions show 11.7% higher acceptance than non-tokenized ones.
• Frictionless experiences: Combined with biometric authentication, it enables “invisible payments” where the customer does not manually enter data.
• Simplified compliance: Tokenization helps meet PCI DSS standards more efficiently.

Digital wallets and verified identity

More than 60% of the global population will use digital wallets in 2026. At the same time, we will see the expansion of digital identity wallets that facilitate access to services by verifying age, identity, and transactional reputation.

Immediate actions:

• Implement Click to Pay for one-click payments from any device.
• Offer multiple wallet options (Apple Pay, Google Pay, Samsung Pay) adapted to each market.
• Prepare for verified alias systems that will replace complex cryptographic addresses, reducing fraud.

Implementation strategy: From theory to practice

Gradual migration without losing sales

1. Coexistence phase (2-4 weeks): Keep PayPal active while you implement the new gateway. Use A/B tests to compare conversion rates.
2. Incentivize the new method (1-2 months): Offer a small discount (1-2%) or free shipping for those who use the new payment method.
3. Checkout redesign (month 3): Based on data, optimize the presentation of payment options, highlighting the most effective one.
4. Evaluation and adjustment (continuous): Monitor key metrics: conversion rate by method, cost per transaction, and customer satisfaction.

Simplified international legal compliance

For global sales, Merchant of Record (MoR) solutions like FastSpring automatically manage:

• Taxes in more than 55 countries, 13 provinces, and 45 U.S. states.
• GDPR and CCPA compliance for data protection.
• Annual renewal of PCI DSS Level 1 certification (the highest).
• Automatic regional restrictions, such as recurring payment limits in India (₹15,000 ≈ $170).

Conclusion: Your roadmap by business type

• Spanish ecommerce (domestic sales): Redsys + Bizum is your optimal combination. You reduce costs from 3.4% to 0.4% and offer the preferred method of 27 million users.
• SaaS/Digital products (global market): Consider a Merchant of Record like FastSpring that manages global taxes, compliance, and fraud, or Stripe if you prefer greater control with somewhat more administrative complexity.
• Sales in Latin America: Mercado Pago is essential for accepting cash payments like OXXO and PagoFacil.
• Enterprise company (high volumes): Adyen offers scalability and advanced reporting, though with greater integration complexity.

The final decision must balance: (1) cost per transaction, (2) conversion rate, (3) geographic coverage, and (4) available technical resources. Start with a 30-60 day trial rigorously measuring the impact before fully committing.

Have you already identified what the bottleneck is in your current checkout? The first step to optimizing your payment gateway is understanding exactly where your customers abandon and which methods they prefer in your specific market.
