The short version

  • Each has a real cost: Codat the accounting platforms are metering developer access themselves, with Xero introducing tiered connection based developer pricing from 2 March 2026, so a cost you do not control has been inserted between you and the data and it scales with the number of customers you connect.; 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: Codat covers Normalised accounting API, Neonomics covers Payment initiation.
  • 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.

Codat

  • The accounting platforms are metering developer access themselves, with Xero introducing tiered connection based developer pricing from 2 March 2026, so a cost you do not control has been inserted between you and the data and it scales with the number of customers you connect.
  • Pricing is opaque and enterprise shaped for a product developers expect to evaluate technically first, so build decisions get made before anyone knows the unit economics.
  • Normalisation hides but does not remove the underlying differences between accounting systems, and edge cases in multi-currency, journals and tax handling surface as data quality problems that your team must reason about in each source system anyway.
  • Data quality depends on the small business keeping its books properly, so a lender using ledger data for underwriting inherits the bookkeeping standard of its worst borrower and needs its own validation layer regardless.
  • Connection breakage from expired tokens and platform API changes is an ongoing operational load, and a borrower whose connection lapses stops being monitored silently, which is the failure mode that matters most in a lending portfolio.

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

Codat: What is changing with Xero in 2026?

Xero is introducing a tiered, usage based developer pricing model effective 2 March 2026, with tiers based on the number of customer connections an app holds. That is a new cost in the chain for anyone reading Xero data at scale, whether directly or through Codat.

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.

Codat: Can Codat write data back?

Yes. It supports pushing bills, payments and journal entries into accounting systems, not only reading from them.

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.

Codat: Is pricing published?

No. It is quoted by connected companies, data types and products, and users consistently describe it as opaque.

Neonomics: Does Neonomics hold merchant funds?

No. It initiates payments; settlement, reconciliation and refunds remain with the merchant or its payment provider.

Codat: Does it replace bank data aggregation?

Not entirely. It covers banking alongside accounting and commerce, but lenders commonly run it beside a bank aggregator for transaction level cash flow.
