Hello,I made a business purchase from a business seller using a €10 eBay discount voucher.I asked the seller for an invoice (which is valid for accounting purposes since eBay does not provide one), however the amount they received is, of course, €10 higher than the amount that was charged to me... How can this be justified for accounting purposes if eBay does not provide an invoice? Do you have a solution?

@zarayonfr well, proof of purchase and a screenshot that should do it, right !!!!!!!!!!
