Where each one falls short

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

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

Trustly

  • It is majority-owned by Nordic Capital, a private equity firm, so its long-term roadmap is ultimately oriented toward an eventual sale or IPO rather than indefinite independent operation.
  • Consumer familiarity with paying by bank transfer still lags card payments in most markets, so merchants typically see it used as a secondary option rather than a full card replacement.
  • The 1.15 to 3.15% merchant fee range is not a single published rate, so a merchant cannot know its actual cost without a sales negotiation.
  • As with all open banking-dependent payment methods, reliability depends on the consistency of the underlying banks' own APIs, which Trustly does not control.
  • Its verified payout functionality is heavily used in gaming and gambling, a sector with additional regulatory scrutiny, which is worth factoring in when evaluating vendor risk exposure by association.
