Features
Everything between the invoice and the tax return
One account on your phone, tablet and computer, kept in your business currency.
See who has paid
Record each payment as it arrives. Invoices show Unpaid, Partial or Paid, and tax your customer withheld is counted too.
Tax and VAT, already worked out
A single rate or a progressive table, cash or accrual, registered for VAT or not. The dashboard does the sums every month.
Reports for you and your accountant
Income, expenses, VAT and tax by month for any period, and seven PDF reports: revenue, payments, invoices, expenses and VAT.
Any currency, one set of books
Each payment and expense keeps its own exchange rate: fetched for its date, or the one your bank used.
Ask instead of searching
The assistant reads your invoices, customers and expenses, answers in your language, and creates records when you ask.
On every device, in your language
The same account on iPhone, iPad, Android and in the browser, in 34 languages. Or work from Telegram and AI clients.

FAQ
Questions people ask first
Is Mini Accountant free?
Yes. Every feature is free on iPhone, iPad, Android and the web. The optional Pro subscription removes the “Powered by Mini Accountant” line from your invoices and reports.
Who is it for?
Sole proprietors, freelancers and small businesses that invoice customers, track expenses and need to know what VAT and tax they owe.
Can I invoice customers in different currencies?
Yes. Each customer has their own currency, and their invoices use it. Every payment and expense keeps its exchange rate into your business currency, fetched for its date or typed from your bank, so the totals and reports add up in one currency.
How does it work out tax and VAT?
You set the tax base (income, or income minus expenses), cash or accrual basis, a single rate or a progressive table, and whether you are registered for VAT. The dashboard and reports follow these settings month by month.
Can I record partial payments?
Yes. Add each payment to the invoice as it arrives; the invoice shows Partial until it is paid in full. If your customer withheld tax, record it with the payment and the reports count it as tax already paid.
What reports can I make?
Seven PDF reports for any period: revenue with VAT and tax by month, payments received (in total and by month), invoices issued, expenses (in total and by month), and VAT on payments by month.
Can I use it on several devices?
Yes. Sign in with the same account on your phone, tablet, or at miniaccountant.app in a browser. Everything you enter on one device appears on the others.
Can I use Mini Accountant from Claude, Cursor or Telegram?
Yes. AI clients that support MCP connect through mcp.miniaccountant.app (see the setup guide), and the Telegram bot @ai_mini_accountant_bot works with the same account.
Which languages does it support?
34 languages, from English, German, French and Spanish to Ukrainian, Greek, Arabic and Hebrew. The app and its built-in guide follow your choice, and the assistant answers in your language.
Can I try it without an account?
Yes. Start without an account and register later from the menu to keep your data. Data from an account you never register is cleared after 30 days.
How do I delete my data?
In FAQ & Settings, choose to delete your personal data and confirm with your password. If you sign in with Apple, Google or GitHub, write to support@miniaccountant.app.
