The short version

  • Only Zeplo has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; 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: Paymentology covers Global issuer processing, 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.

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.

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.

Answered from the vendors’ own pages

Paymentology: Does Paymentology provide the BIN and licence?

No. You need your own issuing licence or a sponsor bank in each market; Paymentology processes the transactions.

Zeplo: How does Zeplo work?

You prefix your endpoint URL with zeplo.to and add query parameters for retries, delay, cron or concurrency. No SDK or broker is needed.

Paymentology: What is the actual pricing model?

Per transaction and per active card, with a monthly minimum. Dormant cards still cost, so model your activation rate.

Zeplo: What does it cost?

Free for 500 requests a month; 39 US dollars a month for a million requests, then 10 dollars per additional million.

Paymentology: Why choose it over a United States issuer processor?

Network certification and live programmes in markets where those processors do not operate, which decides feasibility rather than preference.

Zeplo: Is it suitable for critical jobs?

It is a small vendor in your execution path with no published SLA below Enterprise, so weigh that against the convenience.

Zeplo: Does it work with serverless platforms?

Yes, that is its main use, covering Vercel, Cloudflare Workers, Netlify and similar environments that lack long-running workers.
