Four tools, one ledger

Each one works alone. Together they close the month for you.

  • Timer

    Start it from the menu bar. Hours land on the right client.

  • Invoices

    Numbered, dated and totalled. Send as a link or a file.

  • Reminders

    A polite nudge on day 7 and day 14, then it stops.

  • Reports

    Income by client and by month, ready for your accountant.

From the changelog

  • "I sent four invoices before my coffee went cold."

    NA Noor A., two-person print studio

  • "The reminder did the awkward part for me."

    JB Jonas B., illustrator

  • "My accountant asked what changed. Nothing, it is just tidy."

Moving in

Bring your old invoices

Upload a spreadsheet and the ledger is filled in for you, client by client. Numbers, dates and totals are kept as they were, and nothing is sent to anyone until you say so.

Most studios are moved in before the kettle has boiled.

How the import works
Is there a contract?

No. You pay by the month and stop when you like.

Can I bring old invoices?

Yes, as a spreadsheet. Numbers and dates stay as they were.

What does it cost?

A flat 9.00 a month for the whole studio.

Close the month on a Friday

Thirty free days, every feature, and an export button that always works.

Your first invoice

An invoice is a client, a list of lines and a due date. Everything else is optional, and most of it can wait until somebody has paid.

What a good invoice has

Keep each line to what the client received. Set the term in the field named due_in_days and leave the rest at its default.

  • One line per piece of work, in plain words
  • A due date that is a real date, not "on receipt"
  • Bank details where nobody has to look for them

After it is paid

Mark it as paid, send a one-line thank you, and reuse the invoice as next month's template.

See one finished

The sample invoice has four lines, a due date and one overdue reminder.
