What to Consider When Choosing a Credit Card Processor in the EU
1. Licensing and Compliance
Ensure your processor holds an EU e-money or acquiring license and complies with PCI-DSS, PSD2, and local financial regulations.
2. Settlement Times
Look for providers offering timely, multi-currency settlements, especially if you deal in non-EUR transactions.
3. Support for High-Risk Business Models
If you operate in verticals like gaming, crypto, or adult services, not every processor will work with you. Prioritize those with high-risk experience.
4. Fraud Protection and Chargeback Management
Chargebacks can hurt your margins and reputation. Strong anti-fraud tools and active chargeback monitoring are critical.
5. Fee Structure
Evaluate setup fees, interchange costs, chargeback fees, and monthly maintenance. Opt for transparent, flat-rate pricing where possible.
