Codat

One API for small business accounting, banking and commerce data

As of 31 August 2026, Codat's pricing is not published; the vendor quotes on request. Codat normalises data from QuickBooks, Xero, NetSuite and similar into one model so lenders and banks can underwrite a small business without asking for PDFs. Softwr lists it under APIs. Codat is made by Codat Limited, available on API, Web.

Overview

What Codat does

Codat is a data platform for small business financial information. It connects to accounting packages, banking, commerce and payroll systems used by small firms, retrieves invoices, bills, ledgers, chart of accounts, transactions and sales data, and presents them through one normalised API so the consuming product does not have to learn each source individually. On top of that it offers products aimed at specific jobs: lending, where the data supports underwriting and monitoring; supplier onboarding; and business account verification. What distinguishes it is the normalisation and the vertical framing. Every accounting system models a bill or a journal slightly differently, and the work of reconciling those models is the thing a lender does not want to build. Codat sells the reconciliation rather than the raw connectors, and packages it as underwriting and monitoring products rather than as a data pipe, which is why its customers are commercial banks, payment companies and business lenders rather than developers building sundry integrations. The buyer is an enterprise financial services team. There are two trade offs worth stating. First, pricing is opaque and enterprise shaped, which sits awkwardly with an API product that developers expect to trial. Second, and more consequential, the underlying platforms are asserting control over their own developer ecosystems: Xero is introducing tiered usage based developer pricing from 2 March 2026, with tiers keyed to the number of customer connections an app holds. That cost lands somewhere in the chain between the platform, Codat and you, and any multi-year model of unit economics built before it should be rebuilt.

What people use it for

A business lender that wants live ledger data for underwriting rather than a borrower emailing exported PDF accounts
A commercial bank monitoring covenant compliance across a portfolio of small business borrowers continuously rather than quarterly
A payment company verifying a merchant trading history before extending working capital
A B2B platform writing bills and payments back into a customer accounting system so reconciliation happens automatically

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about 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.

Questions people ask

Each answer names the page it came from, so you can check it rather than take our word for it.

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.

Can Codat write data back?

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

Is pricing published?

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

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.
