Make invoices and quotes in any currency, get paid, and see where your money is. Free, with no account, and it works offline.

Other platforms

Version 1.0.0 · Free · macOS, Windows, Linux

An invoicing app that runs on your computer: invoices and quotes in your own style and in any currency, each keeping the rate of its own date, VAT done right, banks and wallets on every invoice, a dashboard of what you invoiced, collected and are still owed, thirteen reports for your accountant, and Peppol e-invoices. Keep everything in one file, or share one PostgreSQL database with your whole team. Nothing needs an account, and your records stay with you.

See where your money is

The dashboard adds up what you invoiced, what came in, what is still owed and what is late, for today, this month, this year or any period you choose, with your best clients and items beside it.

  • Invoiced, collected, outstanding and overdue
  • Every currency converted into yours
  • Top clients, top items and what is late

Invoices that look like your business

Your logo, your colours and your layout, in English, French or Arabic, with Arabic right to left. Preview the PDF as you type, then print it or save it.

  • Style profiles, layouts and four Arabic fonts
  • Discounts, surcharges, shipping and VAT per line
  • PDF, print, and Peppol e-invoices

Every line adds up

Pick an item and its price and unit fill in. Give each line its quantity, discount and tax, add your own columns, and watch the subtotal, tax, total and balance due update as you type.

  • A tax rate on each line, or one on the whole invoice
  • Custom columns for references, dates or anything else
  • Drag lines into the order you want

Change the look as you watch

Open the preview and customize it: page size, fonts, your colour and logo, the table, watermarks and every label. Like what you see? Save it as a style profile and use it again in one click.

  • A4 or Letter, nine fonts, three table styles
  • Watermark, and a paid stamp on paid invoices
  • Save any look as a style profile

Arrange every part of the page

The layout builder places the header, items, totals, payment information, notes and signature exactly where you want them, with rows, columns, regions and grids. Start from Classic, Modern or Compact.

  • Build visually, with undo and redo
  • Side-by-side regions and landscape pages
  • Export and import layouts as files

Quotes that become invoices

Send a quote, and turn it into an invoice in one click when the client says yes. The quote closes itself and keeps the link to its invoice.

  • Every quote open, accepted or closed
  • One click from quote to invoice
  • A report of how many quotes you win

Every currency, at the right rate

Choose your default currency once. Every invoice keeps the rate of its own date, so changing a rate later never rewrites an old invoice, and foreign-currency invoices show their VAT in your currency.

  • A rate for every currency, kept on each invoice
  • VAT in your currency, as EU rules ask
  • Dashboard and reports in one currency or all

The reports your accountant asks for

Thirteen reports, from sales by month, client, item and business to VAT by rate, the sales register, payments received and client statements. Every one exports to Excel.

  • VAT by rate for your return
  • Sales register, statements and aging
  • Excel export with every row

Know who owes you, and since when

Aged receivables split what each client owes by how late it is. Outstanding invoices, payments received and client statements show the rest.

  • Current, 30, 60, 90 days and more
  • Partial payments and invoices marked paid
  • A statement for any client and period

Every client’s account, line by line

Pick a client and a period: the statement starts from the opening balance, lists every invoice and payment, and ends on what they owe today. Print it or send it to Excel.

  • Opening and closing balance
  • Invoices and payments in date order
  • In one currency or all converted into yours

The invoices you send every month, in seconds

Save a preset with the business, client, currency, banks and wallets, style and notes. A new invoice from it only needs its lines and dates.

  • One preset per client or per kind of job
  • Notes and terms filled in for you
  • For invoices and quotes alike

Clients, items and businesses

Keep your clients, products and services, and invoice from several businesses, each with its own details, numbering and style.

  • Clients with their invoice and quote counts
  • Items with units, categories and prices
  • Several businesses in one app

A look at the real screens
