Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Paymentology
- Paymentology processes but does not hold issuing licences, so every market still needs your own licence or a sponsor bank, which is usually the slowest and most expensive part of a launch.
- Fees include per active card charges and monthly minimums, so a portfolio with many dormant cards pays for plastic that generates no interchange.
- Certification, settlement and scheme relationships differ by country, so a multi market rollout is a series of separate projects rather than one integration.
- As a processor it sits between your product and the networks, meaning outages and scheme mandate changes reach your cardholders through a party you do not control.
- Documentation and developer self service are weaker than the United States hosted processors, so early integration depends heavily on Paymentology implementation staff.
Thunder Client
- Paid plans are billed annually only: Starter is $3 per user per month and capped at a maximum of 10 seats, Business is $7 per user per month with 500 monthly collection runs per user, and Enterprise is $16 per user per month for unlimited runs
