on / in a bill / invoice

[Verona_82]

Hello,

A friend of mine asked me whether she should say "information on the invoice' or 'information in the invoice'. On the one hand, an invoice is a kind of bill, and, if I'm not mistaken , we say 'on a bill'. One the other hand, it is a document, as we say 'in a document'. It seems to me either is fine, but I'm not sure. I'd appreciate it if someone could clarify this.

Thank you.

Either seems fine.

Going off-topic, is 'everybody' changing their avatars? First, I didn't recognise freezeframe and now Verona. Welcome in new outfits!

Thanks! The previous one was too girlish :)
