Where each one falls short

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

Fintecture

  • Coverage and merchant adoption are heavily French, so a European rollout means strong performance in one market and a thin experience in the rest.
  • Deferred and instalment payment relies on a financing partner that sets acceptance criteria, so your business customers can be declined for reasons you cannot see or influence.
  • As a payment initiator rather than an acquirer, Fintecture leaves refunds, disputes and settlement structure with the supplier, and there is no chargeback framework at all.
  • Business to business bank payments require the payer to authenticate with their bank, and corporate banking authentication with dual approval is materially clunkier than consumer app redirects, which hurts conversion on large invoices.
  • It is a smaller supplier than the pan European open banking firms, so bank API breakage outside France may take longer to fix and support depth is a legitimate procurement concern.

Kong

  • The Plus plan includes 1M API requests a month and charges $200 a month for each additional million
  • Plus is capped at 10M requests a month, so growth past that forces an Enterprise contract
  • Plus limits published APIs to 20 and includes one Developer Portal, with a second at $200 a month
  • SSO and audit logging are Enterprise only
  • Enterprise pricing is custom and billed annually
