Capium allows you to import an iXBRL report of Abbreviated accounts from other providers and then to submit to Companies House. To do this, head to the Submit page using the navigation above



You need to fill in the details as per the requirement and upload the iXBRL file of abbreviated accounts from your system. Make sure that the ‘Accounting Period’ is the same as mentioned in the imported iXBRL report. Also, the ‘Directors Signing date in the pop-up and the iXBRL report should be the same.




Note: Capium will not perform any kind of validation check on the iXBRL set of accounts generated using other providers. Capium simply submits such iXBRL set of accounts to Companies House and allows the user to get the response, and will not rectify any generated errors in the submitted accounts. You can contact your iXBRL provider to resolve any errors received as a response by the Companies House.

But they should use Company Authentication Code of the specific company they are filing annual returns for.
