Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Adyen

There is a minimum monthly invoice, set by industry and business model and only disclosed through the sales team, so small volumes are not economic
Published fees are indicative rather than a rate card, with real pricing negotiated
Interchange++ means the card cost varies per transaction rather than being a single predictable percentage
Alternative payment methods carry their own rates on top, such as 3.3 percent plus $0.10 for American Express in North America

Seismic

Weak digital sales room and micro-site functionality with low customer engagement
Search feature lacks keyword depth, making content discovery difficult
Limited learning and LMS capabilities with underwhelming analytics and reporting
Complex implementations requiring dedicated internal resources and strong change management
High price point with multi-year contracts and no free trial option
