SWawi easyNot a web portal.
A real Mac app.
Invoicing for tradespeople and freelancers. Starts instantly, saves locally, knows dark mode and keyboard shortcuts – and writes XRechnung, ZUGFeRD and the Swiss QR-bill.
€34.99 one-time · 10 invoices free
Built by Marcel Altherr in Eschweiler, Germany. No corporation, no investors, no sales team – write in, and the person who built the app is the one who answers.
Everything you need – and nothing that gets in your way
Enter your company details, write your first invoice, done. No seven-step setup assistant, no manual.
XRechnung & ZUGFeRD
Electronic invoices to EN 16931. XML export, ZUGFeRD PDFs and a validator for incoming invoices – all included.
One-time purchase, no subscription
Pay once, use it for good. Updates are free. The app runs locally and needs no server – a subscription would not be honest.
Audit-proof records
Once issued, invoices are stored unalterably and cannot be deleted. A daily backup runs alongside, automatically.
Documents to your taste
Three designs, a free accent colour, every installed font, your own logo and letterhead. Two letterheads as well, for a business with two arms.
Dashboard & dunning
Revenue, outstanding amounts, overdue invoices and top customers at a glance. Four dunning levels, each with its own fee, deadline and text.
Made for Austria too
ebInterface 6.1 for invoices to federal bodies, plus the Austrian rates including the 19 % for Jungholz and Mittelberg.
And for Switzerland
QR-bills to the SIX standard with payment part and receipt, billing in CHF, Swiss VAT rates and the exemption under Art. 10 MWSTG.
Small-business rule § 19 UStG
One switch, and the required note is printed automatically. For Austria under § 6 UStG accordingly.
You still write an invoice in three minutes. Every feature waits until the first time you go looking for it – and none of them costs extra.

Questions that come up before buying
Do I really need XRechnung?
Since January 2025 businesses in Germany must be able to receive electronic invoices, and from 2028 sending them becomes mandatory for everyone, without exception. SWawi easy already has XRechnung and ZUGFeRD built in, so you are prepared.
Why aren’t Word and Excel enough for invoices?
Invoices in Word or Excel can be altered at any time without leaving a trace. German GoBD rules, however, require that records cannot be changed, that every step remains traceable, and that documents are archived tamper-proof for ten years. SWawi easy meets this: once an invoice has been issued it is archived and can no longer be edited.
How safe is my data?
Your data belongs to you and stays with you. SWawi easy keeps everything locally on your Mac – no cloud upload, no server, no account. Even if our website went offline tomorrow, your app would keep working exactly as before. On top of that, SWawi creates automatic backups so nothing gets lost.
What happens after the 10 trial invoices?
All your data is kept – customers, products, everything. You simply unlock the app with a one-time purchase and carry on where you left off. Nothing is lost, nothing starts over.
Does SWawi easy make me GoBD-compliant automatically?
SWawi easy handles the technical side: once issued, invoices are stored unalterably, with automatic backups and logging. Full GoBD compliance also requires your own process documentation – a document describing your workflow. That is independent of the software and applies to every invoicing program.
Which macOS versions are supported?
SWawi easy runs on macOS 14 Sonoma, macOS 15 Sequoia and later releases.
Is SWawi easy available as a subscription?
No, and that is deliberate. The app runs locally and needs no server, so charging a recurring fee would not be honest. Buy once, use it for good.
What about partial payments?
You can record incoming payments individually and see the outstanding balance at any time. Entry is manual – there is no bank connection, but you stay in full control.
Does SWawi easy work in Austria?
Yes. Since version 1.1 SWawi easy supports Austrian ebInterface 6.1 (the mandatory format for invoices to federal bodies), the Austrian VAT rates (20 / 13 / 10 / 0 %) including the special 19 % rate for Jungholz and Mittelberg, and the small-business exemption under § 6 UStG (AT).
Can I use SWawi easy in Switzerland?
Yes. Since version 1.5 SWawi easy produces QR-bills to the SIX Group standard with payment part and receipt, bills in Swiss francs, and knows the VAT rates 8.1 / 3.8 / 2.6 / 0 % as well as the note on VAT exemption under Art. 10 para. 2 MWSTG for annual turnover below CHF 100'000.
Ten invoices to find out
Every feature unlocked, no credit card, no account. If it fits, you unlock it – if not, you have lost nothing.
