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.; Griffin platform banking carries a one-off onboarding fee from 15,000 pounds and a 3,500 pound monthly minimum, which prices out early-stage companies entirely.
  • They diverge on capability: Codat covers Normalised accounting API, Griffin covers Bank accounts by API.
  • 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.

Griffin

  • Platform banking carries a one-off onboarding fee from 15,000 pounds and a 3,500 pound monthly minimum, which prices out early-stage companies entirely.
  • It is UK-only, so a business with European or US operations needs a second banking provider and a second integration for those entities.
  • It is a young bank with a small balance sheet relative to incumbents, and enterprise counterparties still ask hard questions about concentration risk.
  • Holding a banking licence means Griffin applies bank-grade due diligence to its own clients, so onboarding is slower and more selective than an EMI-based provider.
  • Feature breadth is narrower than long-established providers, particularly in card programme management and in payment types beyond core UK rails.

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.

Griffin: Is Griffin actually a bank?

Yes. It received a UK banking licence with restrictions in March 2023 and a full licence in March 2024 after exiting mobilisation.

Codat: Can Codat write data back?

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

Griffin: What does it cost?

Business banking from 100 pounds a month; platform banking from a 15,000 pound onboarding fee plus a 3,500 pound monthly minimum drawn down by usage.

Codat: Is pricing published?

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

Griffin: Does it cover Europe?

No. Griffin is a UK bank serving UK accounts and UK payment rails.

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.
