Clehance Connect · Universal accounting API

Integrate once. Reach every ledger.

Your platform talks to one API. Your customers connect the accounting system they already use. Invoices, payments, contacts and ledger entries come back normalized, whatever sits underneath.

Born inside a production B2B fintech platform · a Clehance product

Why Connect

Four things incumbents don’t give you.

Drop-in migration

Connect is API-compatible with incumbent aggregators. If you already integrate one, switching is a base-URL change and a credential swap, not a rebuild. Your existing code keeps working.

Built for AI agents

Every endpoint is exposed twice: a REST API for your application and an MCP server for your AI agents. An agent can list overdue invoices or draft a ledger entry the same way your backend does.

Deep local coverage

We cover the systems businesses actually run, starting with the Dutch and Benelux market, including the local systems US vendors skip. Each system we add serves every customer at once.

Your infrastructure or ours

Run Connect as hosted SaaS, or deploy it inside your own perimeter when the data cannot leave. Same API either way. You pick the risk posture; the integration doesn’t change.

How it works

Three steps from zero to every customer’s books.

01 — Integrate

One API, one afternoon

Point your backend at the Connect REST API, or plug the MCP server into your agents. If you come from an incumbent aggregator, keep your existing calls.

02 — Your customers link up

A consent flow, not a project

Each of your customers authorizes their own accounting system through a hosted connection flow. No credentials pass through your hands.

03 — Read and write

Normalized, both directions

Invoices, payments, contacts, journal entries: read them and write them through one schema. Connect handles each ledger’s quirks so you never see them.

Coverage

Driven by what your customers run.

Connectors for the major Dutch and Benelux accounting systems are live in production today, and new systems are added continuously. Every connector we ship serves all customers at once, so coverage compounds.

Who it’s for

Platforms whose customers keep books.

B2B fintechs

Banking & spend platforms

Sync transactions and invoices with each customer’s ledger automatically, instead of maintaining a zoo of one-off integrations.

Lenders

Credit & factoring

Underwrite on live financials pulled straight from the borrower’s accounting system, with their consent, instead of quarter-old PDFs.

Vertical SaaS

Software with invoices inside

If your product creates or receives invoices, your customers want them in their books without retyping. One integration gives them that.
