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.
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.
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.
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.
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.
Documents
Invoices collected from the mailbox, delivered to the platform.
Clehance Connect can also collect invoices and receipts for a platform’s customers from the sources where they arrive: a Gmail mailbox, a Google Drive folder, an Outlook mailbox or a Dropbox folder. The customer connects a source once, from inside the platform. Connect then checks it on a schedule, keeps the documents that look like invoices, drops the duplicates, and delivers them to the customer’s workspace on the platform.
Read-only access
Connect reads mail and files; it never sends, edits or deletes anything in the customer’s account. For Gmail and Google Drive it asks only the read-only permissions.
Invoices only
Each new message or file is checked for an invoice or a receipt. Everything else is ignored and not kept. A document seen once is delivered once.
Nothing kept after delivery
A document is stored only until it reaches the platform, then deleted. The connection can be revoked at any time, from the platform or from the customer’s Google account.
How Connect handles the data it reads from Google accounts is described in the privacy policy.
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.
Banking & spend platforms
Sync transactions and invoices with each customer’s ledger automatically, instead of maintaining a zoo of one-off integrations.
Credit & factoring
Underwrite on live financials pulled straight from the borrower’s accounting system, with their consent, instead of quarter-old PDFs.
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.
