The short version

  • Only Thunder Client has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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; Zimpler pricing is not published and is set by industry and risk profile, so smaller merchants cannot benchmark a quote and often discover they are paying well above a general-purpose provider.
  • They diverge on capability: Thunder Client covers REST Client, Zimpler covers Bank payments.
  • Prices and features above were last checked on 1 September 2026.

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

Zimpler

  • Pricing is not published and is set by industry and risk profile, so smaller merchants cannot benchmark a quote and often discover they are paying well above a general-purpose provider.
  • As a payment facilitator carrying merchant risk, it declines or offboards merchants on risk grounds, which makes it a dependency you cannot assume will persist.
  • Its strength is concentrated in the Nordics, and coverage in southern and eastern Europe is thinner than pan-European account-to-account specialists.
  • Revenue concentration in iGaming ties the provider to a sector under constant regulatory change, so licence changes in one market affect the supplier as well as the merchant.
  • Bank transfers have no chargeback protection, so disputes are handled commercially and consumers used to card protections may resist the payment method.
