Invoicing for self-employed people in Switzerland

When you work on your own, invoicing should not take up an evening every month. Here is how to produce a compliant invoice with a QR code quickly, from your first assignment to year-end, without using full accounting software.

What a self-employed invoice should contain

A Swiss invoice fits on one page: your full details, the customer's details, a unique number, the date, a breakdown of services, the total and payment details. If you are VAT-registered, your UID with the VAT designation and the applied rate are also required.

Everything else is about convenience: a clear due date, a reference the customer can find in their accounting system, and a readable payment section that prevents data-entry errors.

Number invoices without mistakes

Numbering should be continuous and without gaps. A format such as I-2026-0001 is enough and remains readable for years. The important thing is never to reuse a number, even after cancellation. Instead, issue a new invoice that replaces the previous one.

Get paid faster

Three things make the difference: send the invoice on the day of the service, set a short and explicit due date, and offer payment without re-entering data through the QR section. The customer scans, confirms and pays.

Tracking matters just as much as sending. An invoice marked overdue from the day after its due date lets you follow up at the right time without having to remember.

The monthly routine in four steps

  • Invoice each assignment as soon as it is completed, not at the end of the month
  • Check the VAT rate applied to every invoice line
  • Review the list of overdue invoices once a week
  • Export the data for your fiduciary at year-end

Questions fréquentes

Do I have to charge VAT as a self-employed person?
Only if your annual turnover exceeds the VAT registration threshold or if you have registered voluntarily. Otherwise, invoice without VAT and do not show a rate.
How long should invoices be kept?
Ten years. Keep issued documents in a stable, exportable format together with the corresponding data.
Can I invoice in euros?
The Swiss QR payment section supports francs and euros. For a Swiss customer, the franc remains the expected reference currency.
How do I create an invoice as a self-employed person without accounting software?
A simple text document can be legally sufficient, but it does not produce the QR-code payment section that is now expected. An online tool avoids this issue and keeps numbering consistent from one invoice to the next.
Is there a free Swiss invoice template?
Yes. Our free generator works as a ready-to-use template: enter your details and see the complete document, including the payment section, before signing up.
