How to Change Your Logo on Swiss QR Invoices

Every invoice you send is a touchpoint with your clients. A consistent logo helps them recognise the sender; a particular effect on payment speed has not been established.

The QR-bill replaced the former payment slips on 1 October 2022. That does not make a QR payment section compulsory on every invoice. Your logo belongs in the invoice header, not inside the Swiss QR Code or its surrounding clear space.

This tutorial shows you exactly how to customize your Swiss invoices with your logo and check the result in the invoice PDF.

Understanding Swiss QR Invoice Requirements

What is a Swiss QR Invoice?

The Swiss QR-bill replaced red and orange payment slips on 1 October 2022. A QR payment section contains a standardised Swiss QR Code; an invoice without a QR payment section remains possible.

The QR code measures exactly 46 x 46 mm when printed and features a Swiss cross in the center. This standardization streamlines payment processing across Swiss banking systems.

Check the Payment Fields

Check the relevant QR-bill fields:

• QR code (46 x 46 mm with Swiss cross)
• Payment section with structured data
• Creditor information (your business details)
• Amount (if specified)
• Currency (CHF or EUR)
• Reference number (if applicable)
• Additional information field

Whether fields are required or optional depends on the use case and SIX requirements. Check the applicable combination before sending.

Where Your Logo Fits

Your logo belongs in the header, separate from payment information. Keep the payment section, Swiss QR Code and surrounding clear space unobstructed, and check the finished PDF. Placement alone does not ensure invoice compliance.

The key rule: never cover or obscure the QR code. Place your logo in the top section, away from the payment slip at the bottom.

Magic Heidi adds the logo to the invoice document. Check the actual output; a logo does not certify legal compliance.

Upload Your Logo

App source reviewed on 1 November 2026; no logged-in interface test. The reviewed implementation has an invoice customisation area with an invoice logo section and an upload action. Open settings and invoice customisation; the precise menu arrangement can vary.

1. Prepare a preferably square PNG or JPEG logo, as recommended by the app’s guidance.
2. Select the logo upload action and choose the image through your device’s file picker.
3. Wait for saving to finish. The implementation reduces the image to a maximum height of 256 pixels and stores it as PNG.
4. Check the saved logo. You can also remove it in the same area.
5. If an invoice already exists, the reviewed implementation offers a PDF preview through the eye icon. Check the finished document before sending.

The previously stated 512 KB limit, minimum width of 400 pixels and 300 DPI requirement are not verified upload prerequisites. Readability also depends on the image content, resizing and PDF rendering.

Existing Invoices and Other Devices

The logo is stored for the account. Do not assume regenerating an old invoice will always use its original logo. Archive the PDF actually sent. Changing the logo does not alter a file already downloaded or sent to a client.

On another device, check that you are signed into the same account and that the new logo appears after loading. No fixed synchronisation time is promised.

Check Before You Send

After uploading your logo, create a test invoice:

Step 1: Go to Create Invoice or New Invoice.

Step 2: Fill in sample client information and line items.

Step 3: Click Preview to see the full invoice with your logo.

Step 4: Check these elements:

• Logo appears clear and properly sized
• Logo doesn't overlap with client information
• Logo aligns correctly in the header
• QR code remains unobstructed at the bottom
• Overall layout looks professional

Step 5: If everything looks good, save the invoice as a PDF to see the print version.

Troubleshooting Common Issues

Logo Appears Blurry or Pixelated

Cause: Low resolution or small file dimensions.

Solution: Use a higher-resolution version and check it after automatic resizing. A DPI value alone does not guarantee sharp PDF output.

If you only have a small logo file, ask your designer for a larger version, or use an image upscaling tool (though this has limits).

"File Too Large" Error

Check: Record the actual error message. A fixed 512 KB limit has not been established.

Solution: Compress your image using:

• TinyPNG (online tool for PNG files)
• JPEG Optimizer (for JPG files)
• Image editing software like Photoshop or GIMP

For unusually large files, reduce the image dimensions and check readability afterwards.

Wrong File Format Error

Cause: You're trying to upload a PDF, GIF, or other unsupported format.

Solution: Convert your logo to PNG or JPG:

• Use an online converter (PDF to PNG, etc.)
• Open in Photoshop, GIMP, or Preview (Mac) and export as PNG/JPG
• Ask your designer for a PNG or JPG version

Logo Doesn't Display After Upload

Possible causes: An incomplete upload, connection problem or stale display. Check the actual behaviour before assuming a cause.

Solution:

1. Refresh the page or close and reopen the app
2. Check upload completion and your connection before continuing on another device
3. Clear browser cache if using the web platform
4. Check another device using the same account. A display difference does not establish its cause; note the platform and app version if you contact support.

If the issue persists, contact Magic Heidi support through the app or website.

Logo Overlaps with Invoice Content

Cause: Logo file includes excessive transparent space or unusual aspect ratio.

Solution: Edit your logo file in an image editor:

• Crop transparent space around the logo
• Center the logo in a standard aspect ratio (square or 2:1 rectangle)
• Re-upload the adjusted file

Magic Heidi positions logos based on the image file dimensions, so clean files produce better results.

What a Logo Does Not Change

Uploading a logo does not establish that font selection, hex colours, free logo positioning or multiple client-specific templates are available. These options are not promised here. For the full workflow, see create your first invoice.

The payment section must meet the SIX QR-bill requirements independently of branding. Do not cover the QR code or its surrounding clear space with your own image.
