Quick signals
What this product actually is
Adyen is a global payments platform offering all major payment methods through one integration with Interchange++ pricing transparency. Known for enterprise-grade infrastructure and multi-currency flexibility with no setup or monthly fees.
Pricing behavior (not a price list)
These points describe when users typically pay more, what actions trigger upgrades, and the mechanics of how costs escalate.
Actions that trigger upgrades
- Large payment volumes qualify for volume-based discounts
- Global expansion triggers aggregated single-rate pricing discussions
- Multi-product usage may unlock bundle discounts
- Platform or marketplace model directs to custom package design
- High volume or unique business model triggers sales team contact
When costs usually spike
- Interchange++ means you bear card scheme cost variability
- Custom enterprise pricing NOT available for small businesses
- Currency conversion costs not included in published base rates
- Cross-border fees calculated separately based on destination country
- Additional Adyen products beyond payments priced separately
- Geographic payment method restrictions may limit some markets
Plans and variants (structural only)
Grouped by type to show structure, not to rank or recommend specific SKUs.
Plans

Costs & limitations
Common limits
- American Express transactions are expensive (~3.95% payment method fee)
- Interchange++ variability means costs fluctuate by card type and issuer
- Currency conversion costs vary by merchant country (not transparent)
- Cross-border transactions add fees on top of base rates
- Custom enterprise pricing requires sales engagement (not self-serve)
- Some payment methods have geographic restrictions
What breaks first
- American Express acceptance becomes expensive at scale (~3.95%)
- Interchange++ cost variability complicates financial forecasting
- Currency conversion opacity creates budget surprises for global merchants
- Sales engagement requirement slows onboarding for self-serve teams
- Geographic restrictions block certain payment method strategies
Fit assessment
Good fit if…
- Enterprise businesses needing cost transparency and Interchange++ visibility
- Global merchants handling multi-currency transactions regularly
- Companies wanting unified payment method integration
- Businesses with complex payment flows needing custom solutions
- Organizations valuing upfront cost calculation before authorization
- High-volume merchants who can negotiate custom enterprise packages
Poor fit if…
- Heavy American Express volume (~3.95% is expensive)
- Need predictable flat-rate pricing instead of Interchange++ variability
- Require self-service onboarding without sales engagement
- Small business seeking simple, standardized pricing
- Want bundled value-added services (fraud, analytics) included
- In prohibited or restricted business category
Trade-offs
Every design choice has a cost. Here are the explicit trade-offs:
- Interchange++ transparency → Cost variability and forecasting complexity
- No monthly fees → Higher per-transaction costs vs subscription models
- Global payment method coverage → AmEx at expensive 3.95%
- Enterprise customization → Requires sales engagement, not self-serve
- Pre-payment cost calculation → Interchange variability still exists
