That invoice was made in about a minute.

Minu aeg tracks the hours as the work happens and turns them into a finished invoice — the one you are holding came out of it.

Make your own invoice free The hours nobody wrote down are the ones nobody gets paid for.

Most invoices are rebuilt from memory.

Hours get reconstructed from a calendar at the end of the month, rounded down, and typed into a spreadsheet nobody enjoys. Minu aeg captures the work while it happens, so the invoice is already written by the time you need it.

From worked hours to a sent invoice

Track as you work

One click starts a timer that keeps running even if you close the browser.

Pull the hours in

Pick a client and a date range; the tracked time becomes invoice lines with rates and VAT.

Send it

Download the PDF, or export Merit XML straight into Estonian accounting.

What you get on the invoice side

Hours become lines

Tracked time imports into an invoice as descriptions, quantities and amounts.

Estonian invoicing

Registry codes, VAT numbers, IBAN and a numbering format your accountant recognises.

Merit XML export

The e-invoice file Merit Aktiva imports, reconciling to the cent with the PDF.

Never billed twice

Tracked time can be invoiced once — the same hour cannot land on two invoices.

Free to start, including invoicing.

The free plan issues real invoices, with a small monthly allowance. Paid plans lift the allowance and drop the Minu aeg line from the footer.

Questions from people who just got an invoice

Is this a bill I owe to Minu aeg?

No. Minu aeg is the tool the sender used to produce the invoice. Anything owed is owed to them, and any question about the amounts belongs with them.

Can I make invoices like this for free?

Yes. The free plan tracks time and issues real invoices under a small monthly allowance, with no card required.

Why does the invoice mention minuaeg.ee?

Invoices issued on the free plan carry that line. A paid plan removes it.

Does it handle Estonian VAT and e-invoices?

Yes — registry codes, VAT numbers, IBAN and a Merit Aktiva e-invoice XML export that reconciles to the cent with the PDF.

Your hours are worth writing down.

Start tracking in under a minute, and let the next invoice write itself.
