Astraeus implements both for accountancy practices, with one rule that never bends: nothing files, sends or posts without a person approving it. Judgement on tax positions, filings and anti-money-laundering decisions stays with your people. AI drafts and classifies; it does not decide.
If your practice is between 3 and 30 fee earners, the pattern is usually the same. Staff spend January and October chasing clients for records instead of preparing accounts. The partner inbox is the practice operating system. Invoices still get rekeyed even though the practice already pays for capture tools nobody fully adopted. None of this needs a person doing it end to end, and in most practices all of it is still done by hand.
