The short version
- Each has a real cost: Basis Theory the Starter plan is 995 US dollars a month before any volume, which is a real floor for an early stage company and puts the product out of reach of teams tokenising a few thousand records.; Neonomics coverage outside the Nordics and the UK is comparatively shallow, so a pan European merchant will find gaps and inconsistent bank behaviour in southern and eastern markets.
- They diverge on capability: Basis Theory covers Tokenisation API, Neonomics covers Payment initiation.

What people use each for
The jobs each tool is most often brought in to do.
Basis Theory
- A payments company that wants card on file without bringing its own infrastructure into PCI scope and paying for the assessment that followsnot Neonomics
- A merchant locked into a processor by that processor vault that wants to hold its own tokens and route to more than one acquirernot Neonomics
- A fintech collecting bank account and identity data that needs it isolated from its application database before an enterprise security reviewnot Neonomics
- A team that needs to send stored card data to a third party for a one-off integration without that data traversing its own serversnot Neonomics
Neonomics
- A Norwegian or Swedish merchant collecting payments directly from bank accounts to avoid card feesnot Basis Theory
- A debt collection agency sending request to pay messages instead of chasing bank transfers manuallynot Basis Theory
- A software vendor embedding pay by bank into an accounting or invoicing product for Nordic customersnot Basis Theory
- A business needing both UK and Nordic bank payment coverage from one suppliernot Basis Theory
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Basis Theory
- The Starter plan is 995 US dollars a month before any volume, which is a real floor for an early stage company and puts the product out of reach of teams tokenising a few thousand records.
- Starter is limited to the US region, so a company with European data residency requirements is pushed into a quoted Scale or Enterprise agreement immediately.
- Log retention on Starter is 24 hours, which is well below what most security teams expect for a system holding cardholder data and forces an upgrade for reasons unrelated to volume.
- Migrating away means moving card data out of the vault, which requires processor and assessor involvement and is slow, so the portability argument that attracts buyers cuts against them at exit.
- An attestation of compliance covers the vendor environment, not your assessment; your assessor still decides what is in scope, and buyers occasionally discover their integration pattern pulled systems back into scope anyway.
Neonomics
- Coverage outside the Nordics and the UK is comparatively shallow, so a pan European merchant will find gaps and inconsistent bank behaviour in southern and eastern markets.
- It is a small company relative to Tink and TrueLayer, so supplier viability and the depth of engineering support behind bank API changes are genuine procurement questions.
- Payment initiation only means the merchant handles settlement, reconciliation and refunds, and there is no chargeback framework to fall back on.
- Integrating a recently acquired UK business means two regulatory entities and, for a period, two technology stacks, so cross market feature parity is a promise rather than an existing state.
- Conversion is governed by each bank's own authentication experience, and Nordic BankID flows behave differently from UK app redirects, so a single UX cannot be assumed across the footprint.

Answered from the vendors’ own pages
Basis Theory: Does this make us PCI compliant?
It removes cardholder data from your systems and gives you an AOC plus documented responses for most of a SAQ D. Your assessor still determines your scope, and a careless integration can pull systems back in.
Neonomics: Is Neonomics authorised in the UK?
Yes, through the acquisition of Ordo, an FCA authorised open banking payments firm, approved by the FCA and the Norwegian regulator.
Basis Theory: What does it cost to start?
995 US dollars a month on Starter, including 20,000 tokens, a production PCI Level 1 environment and US hosting. Higher tiers are quoted.
Neonomics: Does it support variable recurring payments?
Yes in the UK through the Ordo capability, subject to which banks support commercial VRP; support elsewhere is more limited.
Basis Theory: Can we switch payment processors without re-collecting cards?
Yes, that is the main non-compliance reason to buy it. You hold the tokens and detokenise into whichever processor you route to.
Neonomics: Does Neonomics hold merchant funds?
No. It initiates payments; settlement, reconciliation and refunds remain with the merchant or its payment provider.
Basis Theory: Is data stored outside the United States?
Not on Starter, which is US only. Other regions require a Scale or Enterprise agreement.
