Huismus is a free app for your invoices, quotes and receipts, with the amounts for your VAT return. No subscription and no account: your records simply live on your Mac or PC.
macOS 14 or newer with an Apple chip · Windows 10 or newer · How to open it the first time
No subscription and no trial period. The source code is public, so anyone can see how Huismus works.
There is no Huismus server and no account. Your data only goes somewhere if you turn that on: your backup to your own cloud, an invoice through your own email, your receipts to an AI service you choose, your feedback when you press Send. Beyond that, Huismus only checks for a new version, and you can turn that off too.
With the KOR, Huismus puts your KOR text on every invoice and shows how close you are to your limit. Without the KOR, you charge VAT on your invoices, reverse-charged too, and record the VAT on every receipt. Each quarter you see the amounts per box, ready to copy into your return.
A walk through the app. The customers and amounts are made up.
Choose a customer, type what you did and Huismus works out the total. Issue gives the invoice a fixed number, with no gaps in the series. Paid? You record it with one click.
How to make an invoice →
For every invoice you see whether it's paid, still open or late. Search by number or customer, and filter by year.
Send a quote, record whether the customer says yes, and turn it into an invoice with one click. The customer and the lines come along.

Put a photo of a receipt in a folder that syncs, from your phone too. Huismus picks it up and can have it read by an AI service you choose.
In Process you see the receipt large next to the fields, and you check it. Without the KOR you also fill in the VAT and the rate.
More about receipts →
Revenue, costs and profit, per quarter too. If you charge VAT, VAT return shows the amounts per box for each quarter. For your accountant you download everything as CSV, with the PDFs and receipts.

Connect Huismus to the Claude app with one button. Ask what's outstanding, or have Claude make a draft. Issuing and mailing only happen when you press the button.
Other assistants, such as ChatGPT, work too. For now that takes some technical know-how.

Coming from Moneybird? Huismus takes over your customers, invoices, quotes and expenses one to one, with the PDFs and receipts. First it does a trial run and compares every total to the cent. Only when you're happy does it save anything.
How to switch →
Choose a folder, for example in iCloud Drive or OneDrive, or connect Dropbox or WebDAV, such as Nextcloud. Huismus puts a backup there every day, as long as it is open.

At the first start, choose Try with sample data. Huismus then fills itself with nine years of made-up records, and one button empties it again. Ready to begin? Then you fill in your business details in four steps.
Getting started →
Got a Raspberry Pi, a NAS or a server of your own? Run Huismus in Docker. You open it in the browser, on your phone too, within your own network.
Huismus is open source, made with Django, SQLite and HTMX. Help is welcome: code, translations, testing on Windows, or just a good idea.
Free, no account. Your records stay on your own computer.
