I have sold several products on a single invoice to a supplier in the EU who is now selling part of this order to another customer outside the EU. They want a legalised commercial invoice and certificate of origin from their local chamber but claim to get this I need to supply them with a commercial invoice and suppliers dec. The problem is they want a commercial invoice that only reflects the items they are selling on and not the entire original invoice. Can Or should I supply a commercial invoice that only reflects those parts they are selling on? Or should I supply one to reflect the original sale. I’m confused.
