Stop doing the books.
Stay in control.

Lanthea reads receipts, invoices and bank statements, proposes the entries and reconciles against the bank. You approve with one click, or let the agent do it within limits you set. VAT and the employer return go straight to Skatteverket.

A month in Lanthea.

What comes in gets booked as it comes. What has to go out goes out on its day. Today shows you what waits for you, and nothing else.

Every day
It comes in

Receipts, invoices and bank statements land in the Tray: photographed in the app, forwarded emails, PDFs, the bank. The agent reads, proposes the account and the VAT, and says how sure it is. You approve, or let it approve by itself within limits you set.
The 1st
The month's report is ready

The voucher list, the VAT, the salaries and an SIE file, as one bundle from the 1st. Your accountant reviews it in four steps and closes the month.
The 12th
Skatteverket gets its due

The VAT return and the employer return are made from the books and filed. The receipt stays with you, and what is to be paid stands on Today.
The 25th
The salaries go out

Tax by Skatteverket's table, contributions by year of birth, holiday by the Annual Leave Act, a payslip for each person.

Joined to what is already there.

The sign-in, the tax agency, the bank and the mail are joined to the books, so nothing is copied or uploaded by hand.

BankID

Filed directly

Skatteverket

VAT and the employer return are filed from the books, with a receipt.

The bank

Enable Banking

The account is read every day and reconciled against the vouchers. The link can only read.

The mail

Gmail and others

Receipts and invoices that arrive by email are found by themselves and put in the Tray.

SEB, Swedbank, Handelsbanken, Nordea, Danske Bank, Länsförsäkringar and over 100 more banks, through Enable Banking.

Open to your own agent.

Everything you can do in Lanthea, a program can do. An open API and an MCP server give your own agent, your business system or your accountant's tools the same books you see, with the same roles and the same log.

API

Receipts, invoices, vouchers, reports and salaries, to read and write as a person with the same role would.

MCP

Connect Claude, ChatGPT or an agent of your own to the company's books, and let it ask and book within the limits you set.

The same log

What a program does stands in the history like everything else: who, when and what.

Choose where the model runs.

Lanthea reads and books with language models. Which ones, and where they run, is your choice.

If nothing may leave the EU, choose an all-European chain: models from Mistral or Berget AI, or Claude running in the EU. The books stay in Stockholm either way.

No provider trains on your data. What each provider sees is stated on the page about subprocessors.

Anthropic	Claude	USA or the EU (AWS)
OpenAI	GPT	USA
Google	Gemini	USA
Mistral	Mistral	France
Berget AI	Open models	Sweden

Bring everything. Leave the program.

From Fortnox the SIE files for every year and the whole document archive come along, so the receipts land on their vouchers. From Bokio everything is fetched with an API token. From Visma, and from anything else with an SIE export, the books come year by year. A step-by-step guide for each program, and the move takes an evening.

What comes along

The vouchers, year by year
Customers, suppliers and products
The receipts, on their vouchers
Opening balances and the chart of accounts
The VAT periods already reported

Your books are yours.

Where they are: On servers in Stockholm. Which providers process what is stated openly on the page about subprocessors.
The bank: The link can only read. It goes through Enable Banking, a registered account information service provider, and Lanthea never touches your money.
Who decides: The agent books nothing without someone approving, or the company allowing it within limits: amounts, accounts, never debts to a person.
The history: A voucher is locked once booked and corrected only with a new one. Every change is logged, as the Bookkeeping Act requires.
Out again: The whole books as an SIE 4 file and every document as a zip, whenever you want.
Delete: The company and everything in it is deleted when you say so. The seven-year duty to keep records is yours, and you take the files with you.

Try it on a real company.

The sandbox is Fjällbris AB, a made-up limited company with a year of books, one employee, a bank that is linked and receipts waiting in the Tray. No sign-up. It disappears by itself after a day.
