Why one set of figures helps.

One set of books

Your accounts for Companies House and the accounts sent with your tax return come from the same figures.

Nothing to reconcile

Nothing is typed twice, so both filings are built from the same underlying figures.

Check once

Review the figures once, then file each one from A4O Accounts — no exporting and re-entering.

Confirmations saved

The receipt from Companies House and HMRC is kept against the client for as long as you need it.
