The filing path

Three steps. You stay in control. Nothing is sent until you review it.

Look up your company

Search the Companies House register. We pull your company's details, accounting period and next deadline automatically.

We prepare it to spec

Our engine builds the accounts as iXBRL, tagged to the current FRC taxonomy, the exact format Companies House expects. You confirm the details.

Review, then file direct

See exactly what will be filed, download a copy, then submit straight to Companies House over their filing gateway. You get the receipt.

Built to the standard

Not a form that emails someone. A filing system built to Companies House's strict technical specifications.

Files direct over the Companies House filing gateway, the same channel the register itself accepts, not a re-keyed web form.

Accounts built as iXBRL, tagged to the current FRC taxonomy suite, the machine-readable format Companies House requires.

Validated before it's sent, every filing is checked against Companies House's requirements so it isn't rejected at the gateway.

You get a receipt, the Companies House submission reference, plus a human-readable PDF copy of exactly what was filed.
