The short version

  • Only Zeplo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Tribe Payments running both issuing and acquiring through one vendor concentrates operational risk, since a platform fault affects both sides of a client's card business at once rather than just one.; Zeplo zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
  • They diverge on capability: Tribe Payments covers ISAAC core platform, Zeplo covers URL prefix interface.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Tribe Payments

  • Running both issuing and acquiring through one vendor concentrates operational risk, since a platform fault affects both sides of a client's card business at once rather than just one.
  • Pricing for either the issuing or acquiring modules is not published, so budgeting requires a sales conversation.
  • With roughly 60-plus customers, it is smaller scale than Visa or Mastercard-owned processing infrastructure, which is a factor for a client prioritising vendor size and track record.
  • Its client base and support depth are concentrated in the UK and continental Europe, and the Asia-Pacific presence via Singapore is comparatively newer and less proven.
  • As with any combined issuing and acquiring platform, a client that only needs one side still evaluates and pays for a vendor built around doing both, which may not be the most specialised option available.

Zeplo

  • Zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
  • The free Developer tier includes only 500 requests a month and one team member, so it is a demonstration allowance rather than a usable free plan for anything real.
  • Overage on the Developer tier is 20 US dollars per 100,000 requests, two hundred times the marginal rate on the Company tier, so exceeding the free allowance without upgrading is expensive.
  • Team members cost 15 US dollars each beyond the plan allowance, which is an odd charge on an infrastructure product billed by request volume.
  • Log retention is 30 days on both published tiers, so anything requiring longer audit trails on job execution has to be logged separately.
