Not software you operate.
A system that operates.
Most practice software automates one step and hands the rest back. Vacei runs the work end to end — reading the document, posting the entry, reconciling the bank, drafting the return, gathering the evidence, building the working paper — and brings your people what needs deciding. Three things make that possible across a book of any size.
Your AI is the way in
Other software gives you screens to work in. Vacei gives your AI a way in. Connect Claude or ChatGPT and ask for the work in a sentence — post this month's documents, draft the year-end working papers, what is still missing for March? — and it happens inside your books, with the documents attached. In a firm, every client file is reachable the same way, by any member of staff with the rights to it.
One ledger under everything
Post an entry once and every list that depends on it moves: debtors, creditors, the loan register, bank reconciliation, trial balance, the P&L, the auditor's request list. Nothing is re-keyed between modules and nothing lives in a spreadsheet on the side. In a firm this is the whole argument: the ledger your staff post to is the ledger the audit tests, and the engagement board reports on. One set of numbers, not three systems reconciled by hand at year end.
People decide and sign
High-confidence work posts itself. Anything uncertain — a payment with no document, a supplier nobody recognises — is brought to a person with the question attached, never guessed. Judgement and signatures stay with named people, and the system records who decided what, and when. In a firm that becomes preparer, reviewer and partner, with sign-off gates between them and a record of who cleared what — produced as the work is done, not reconstructed afterwards.
That is what AI-native means here: the routine work is already done when you arrive, and what is left on your desk is the part that needed a professional. See it run a whole practice →
We work behind your firm.
We never sign in front of it.
When a deadline needs more people than you have, A4 Services Limited — a licensed accounting and audit firm in Malta — takes agreed work inside your own portal: bookkeeping, fieldwork, working papers, draft financial statements. Your firm reviews, decides and signs.
We are not registered as statutory auditors in your member state and we do not act as one. We hold no engagement with your clients, we do not contact them, and we do not compete for their work. The registration, the opinion and the signature remain yours.
Accounting software.
Your AI does the routine work.
Your documents, bank, ledger and reports in one place. Connect Claude or ChatGPT and the routine entries post themselves, each with its source attached. Anything the system is not sure about waits for you, with the question and the document beside it.
Manage it yourself
With a connected AI, high-confidence entries can be posted automatically. You handle the entries that need attention, with the documents beside them.
It does the full accounting. Everything is connected.
Post an entry once and every list that depends on it updates. No re-typing between modules, no spreadsheets on the side.
Auditor’s request list. Upload it as it arrived. Vacei finds the figures and documents behind each item from the same connected books, drafts the answers, and leaves anything missing marked for you to check before sending. If your auditor also runs on Vacei, there is no list to upload — the request arrives in your portal and the answer goes back with the evidence attached.
Profit and loss and balance sheet update from the same entry — and the auditor’s request list is answered from it. VAT figures are available from the ledger for your own return preparation.
One sentence to your AI. The agents do the rest.

Claude or

One document, from your inbox
to figures you can file from.
After your AI reads a document there are two outcomes: posted automatically, or brought to you for review.
{{ s.body }}
You can see which stage every document is at, today. Not at year end.
Three portals. One ledger.
Your brand on all of it.
Client accounting, audit fieldwork and practice management running on the same data — not three systems your staff reconcile by hand in February. Take one on its own, or run the whole practice on it. Priced per client, per month.
Vacei Books · your clients' accounting
Every client's ledger in one place, with the document attached to the entry it supports. Agents code, reconcile and draft; your staff review a queue instead of building one. Across the book: who is unreconciled, whose VAT falls due this week, what is still missing before a file can close.
Vacei Audit · fieldwork and working papers
Planning, materiality, procedures, evidence and review, configured to your firm's own methodology on an ISA basis. Requests raised and chased in the client's own portal, answers arriving with the documents attached. Casting and vouching run against the full ledger, cross-referenced back to the assertion they support. Every run recorded — which version, when, what was cleared — for the reviewer and for your inspection file.
Vacei Practice · engagements, deadlines, capacity
The management layer over both. Every engagement with its stage, its owner and its next action. Statutory deadlines tracked against each client, with what is outstanding on each. WIP, recovery, and who has room to take on more. The board a partner opens on a Monday morning.

Vacei was built inside A4 Services Limited, a licensed accounting and audit firm in Malta, and the firm runs its entire practice on it — statutory audits, monthly books, VAT and payroll, on live client work. It was built by auditors who had to use it on Monday. A4 practises in Malta only. Outside Malta we hold no engagement with your clients and never will — any work we take is done behind your firm, inside your portal.
Priced per client, per month.
Running a firm? Priced per client, per month, across whichever portals you take — Books, Audit, Practice, or all three. White-labelling and migration of your existing ledgers are included, not extras. Bring one live client file to the demo and we price it against your actual book.
All prices exclude VAT. No setup fee on the €5 accounting software plan. Creating an account does not charge you — we agree the scope with you first, then invoice you monthly.
Thirty minutes, on your own client file.
Bring a live client — a set of books, or an audit file mid-fieldwork — and we set the agents up on it in front of you. With an accountant from A4 Services Limited, not a salesperson.
With an accountant from A4 Services Limited, not a salesperson. All times Malta time (CET/CEST). No slot that suits? Use the form and we confirm by email, usually the same working day.
