Create Your First Invoice
Now that your company is set up and your bookkeeping mode is chosen, you can create your first invoice right away. Lumabill automatically generates a Swiss QR payment slip (ISO 20022) -- your clients can scan the invoice with their banking app and pay instantly.
Creating an Invoice
Step 1: Start a New Invoice
Navigate to Invoices in the dashboard and click New Invoice. Lumabill opens the invoice editor with a live preview of your document.

Step 2: Select a Client
Click Select Client to choose an existing client or create a new one. For your first client, enter at least:
- Name (company or individual)
- Address (street, postal code, city)
Tip: Client details are saved and automatically available for future invoices. You can also create clients in advance under Clients in the dashboard.
Step 3: Add Line Items
Add one or more line items to your invoice. For each item, specify:
- Description -- What was delivered or performed?
- Quantity -- Number of units
- Unit price -- Price per unit
- VAT rate -- Automatically pre-filled from your settings

Tip: You can insert items from your Catalog. Save frequently used products and services there to create invoices faster.
Step 4: Review Invoice Details
Check the following fields:
- Invoice number -- Assigned automatically in sequence
- Invoice date -- Defaults to today's date
- Due date -- Payment deadline (default: 30 days)
- Currency -- Pre-set to your base currency, but can be changed
Step 5: Preview and QR Payment Slip
The live preview on the right side shows your invoice exactly as it will appear in the PDF -- including the QR payment slip at the bottom.
The QR code contains all payment information (IBAN, amount, reference number) and allows your clients to initiate the payment with just a few taps in their banking app.

Important: For the QR payment slip to be generated correctly, your IBAN must be saved in your company profile. Check this under Settings > Company Profile.
Save and Send Your Invoice
Download as PDF
Click Download PDF to save the invoice as a print-ready PDF file. The PDF includes the QR payment slip on the last page.

- Draft -- Not yet sent
- Sent -- Delivered to the client
