The service
Simple for you, rigorous for the IRS.
You follow your business at a glance, on your computer, your phone or through your AI. We do the bookkeeping behind it, every month.
01
Real-time balances and transactions
Mercury, Relay, Wise, Airwallex, Stripe, Whop: every account flows into your workspace on its own. You always know how much you have, what came in and what went out, without exporting a single statement.
02
Invoices paid faster
Your invoice goes out in your brand with a card payment link: send it at the end of a meeting and your client pays within the minute. In English, French, Portuguese or Spanish, and as a Factur-X or UBL e-invoice for your European clients.
03
Late payments chased for you
An invoice passes its due date: your client gets a reminder, you get an alert, and you see at a glance who owes you what.
04
Your AI connected to your numbers
Your workspace connects through MCP to Claude, ChatGPT and other compatible assistants. Ask for this month's revenue or the list of unpaid invoices, have an invoice drafted, automate a reminder or offer a call to a client who is struggling to pay.
05
A workspace in your name, easy to use
Your workspace lives at your own address, yourcompany.books.altixia.com, in a database reserved for your company. It is available in English, French, Portuguese or Spanish, on desktop and phone, and opens with Altixia ID.
06
Bookkeeping and the IRS: that's us
Every transaction is categorized and backed by a document, every month is checked and closed by our team. Your owner contributions and distributions are tracked separately: those are the amounts on Form 5472, which we prepare.
07
Several companies, several currencies
A US LLC, a Hong Kong Limited, an Irish company: each has its own currency and numbers, and you also see the whole picture. Exchange rates are updated daily.
Your numbers, whenever you want them
No need to wait for an accountant: everything is up to date in your workspace, or one question away for your AI.

Questions
What people ask us before they start
Do I need to know accounting?
No. You see your balances, sales, expenses and invoices in plain words. The accounting vocabulary and the filings stay on our side.
My meeting with a client is ending: can I send the invoice right away?
Yes. Create the invoice from your phone or ask your AI assistant: it goes out with its card payment link, and your client can pay before the call is even over.
A client is late paying: what happens?
On the due date, your client gets a reminder and you get an alert. With your AI, you can also automate the next reminders or offer a call to a client who is struggling to pay.
How does my AI assistant reach my numbers?
Through MCP, the protocol that connects an assistant like Claude or ChatGPT to your tools. Once connected to your workspace, it answers questions about your numbers, drafts your invoices and follows your unpaid invoices, with your permissions and nothing more.
Who keeps my books: you or software?
Our team. Your transactions come in automatically, but every month is checked by a person before it is closed.
Can you send payments from my accounts?
No. The access you give us (read-only token at Mercury and Wise, restricted Stripe key, Relay accountant access) lets us read your transactions, not create them.
Is Form 5472 really included?
Yes, in all three plans: Form 5472 and the pro forma 1120 for the year, prepared from your books and sent to the IRS by fax or mail. The FBAR is included from the Growth plan.
I'm starting mid-year. What about the beginning of the fiscal year?
We bring in up to one year of history, statements and invoices, and that is included in your plan. Beyond that, catch-up is quoted separately.
How long does it take to get started?
Your workspace opens within 48 hours after the call. The first month is closed as soon as the history is brought in.
My company is not a US LLC. Can you still help?
Yes. Books also keeps the accounts of Hong Kong Limited companies and Irish companies, each in its own currency. For another country, let's discuss it on a call.
In which language?
Your choice: English, French, Portuguese or Spanish. Your workspace, your invoices and our team speak all four.
