Stripe vs Redsys for Car Rental: Which to Choose in 2026

Stripe and Redsys are the dominant payment gateways in Spain for car rentals. Real fees, pre-authorization for deposits, and when to use both gateways.
What Redsys is and why Spanish rentals use it
Redsys is the company that manages payment gateways for most Spanish banks. When you sign up for a virtual POS with BBVA, Santander, CaixaBank, Sabadell, Bankinter, Unicaja or ING, what they activate behind the scenes is Redsys. The merchant signs with the bank, which negotiates fees based on volume, card type and industry. That's why there's no public Redsys pricing: each bank applies its own.
What Stripe is and why more rentals combine both
Stripe is an international payment gateway founded in 2010, with European HQ in Dublin. Its model is 100% online: you sign up at stripe.com, validate your business with documentation (tax ID, deeds, admin's ID) and, if everything's in order, you start charging in 1-3 days. No monthly or setup fees: you only pay per transaction.

Pre-authorization and deposit: the detail that matters most in car rental
In car rental you don't just charge the rental amount: you hold a deposit (typically €200-1,500) that you release or capture based on the car's condition at return. This works as a pre-authorization: an operation that reserves funds on the customer's card without charging them. If all goes well, it expires automatically; if there's damage, you capture the amount (full or partial). Both gateways support this, with nuances.
When to choose Redsys, when Stripe — and when both
Choose Redsys if: you already have a good relationship with your bank, you negotiate fees below 0.8%, you invoice more than €10,000/month (where the fixed fee pays off), your customer base is mostly Spanish, you don't need Stripe Connect or multi-account, and you prefer a single banking contact for everything (charges + account + ICO loans).
Checklist before migrating or adding a new gateway
Before switching or adding a gateway, validate these 7 points: 1) Your management software natively supports the gateway you want (Fletaro Pro and Total integrate both, including pre-authorization for deposits). 2) You have the legal documentation ready (tax ID, deeds, admin's ID, IBAN, digital certificate for Redsys). 3) You've validated fees in writing for your real volume, not the initial commercial offer.
