Warning

CII-SR-288: Do not add an electronic address to the tax representative

In short

Warning: worth checking.

CII-SR-288 means the seller's tax representative has an electronic address (URIUniversalCommunication), which EN 16931 does not use. It is only a warning, so the file is still accepted; remove the address to clear it.

What it means

If the invoice names a tax representative for the seller (BG-11), the check looks for a web, email or other electronic address (ram:URIUniversalCommunication) on that party. EN 16931 only has electronic addresses for the seller (BT-34) and the buyer (BT-49).

Why it matters

This is a warning, so the invoice is still accepted. The address would say where to reach the representative, but a recipient that follows the standard does not read it, so it does nothing. It is worth fixing if someone is relying on that address, because it will not get used.

How to fix it

Remove the email, web or other address stored against the tax representative in your invoicing software. In the XML, delete ram:URIUniversalCommunication inside ram:SellerTaxRepresentativeTradeParty. The electronic addresses of the seller and the buyer stay where they are, on the seller and on the buyer.
