Quick answer
No. AllDone does not file anything with Companies House or HMRC, and it does not produce tagged iXBRL accounts. It sits upstream of your filing software: it produces the complete file, the financial statements content and the corporation tax computation, and gives you the exports to key or import into the tool you already file from. The terms say the same thing.
What you get instead
The corporation tax filing pack, which sets out the computation and the figures the return needs.
A transcription file for CT software, so the return can be populated rather than retyped from scratch.
The final trial balance in two languages: in statement lines for your accounts-production tool, and in the client's own account codes.
The financial statements on screen and in Word, full members' set and filing copy, with the disclosure checklist beside them so you can confirm every note is present in whatever you file.
The exports guide lists every file, which system it goes into, and the order. See The exports guide: which file goes where, in what order.
What AllDone does read from Companies House
Company details, officers and filing deadlines are fetched from the Companies House public data to pre-fill and check a client record and to drive the deadline dials. That is a read. Nothing about your client is sent to Companies House.
Why this matters for your process
The director still signs the accounts, and the firm still submits. Nothing about your professional obligations or your filing route changes: AllDone removes the preparation work and hands the finished file to the software you already use.
