Warning

CII-SR-291: Do not add a logo to the tax representative

In short

Warning: worth checking.

CII-SR-291 means the seller's tax representative has a logo file (LogoAssociatedSpecifiedBinaryFile), which EN 16931 does not use. It is only a warning, so the file is still accepted; remove the logo to clear it.

What it means

If the invoice names a tax representative for the seller (BG-11), the check looks for a logo image (ram:LogoAssociatedSpecifiedBinaryFile) attached to that party. EN 16931 has no place for a logo on any party.

Why it matters

This is a warning, so the invoice is still accepted. Software that reads the structured data does not use the logo. If the element holds the image itself, it also makes the file larger for no gain. It is worth fixing if your files are large or you want no warnings.

How to fix it

Turn off the logo for the tax representative in your invoicing software, or in its e-invoice export settings. In the XML, delete ram:LogoAssociatedSpecifiedBinaryFile inside ram:SellerTaxRepresentativeTradeParty. A logo belongs on the visible PDF copy of the invoice, not in the structured data.
