Type it in Claude on your phone, or in Claude or ChatGPT on the web. Vacei keeps proper books behind it.
An illustration with fictional figures. On a phone, a business owner asks Claude to record a supplier bill they have already uploaded through their Vacei upload page. Claude proposes the entry, the owner confirms it, and it is posted with an audit trail: in the Vacei Books portal the new ledger line appears, the creditors total goes up by the same amount and the VAT owed this quarter goes down by the bill’s input VAT. The owner then asks how much VAT is owed this quarter, and who owes them money; Claude answers with the figures the portal shows.

Why now
The biggest firms in the world were built on people: 1,500,000+ people across the Big Four.
Four firms take 86% of EU public-interest audit revenue. Billed by the hour.
“Computer” used to be a job. A building full of people doing calculations became a laptop.
Accounting and audit are next. The next Big Four will be AI-native.
