I do a small amount of digital goods sales in France. The sales are all online transactions with Paypal, Google Checkout or credit card and it seems that often I am asked for an invoice.
The want for a company generated invoice seems to happen almost exclusively from France... Should the order payment success notification from the particular money processor work as an invoice or proof of purchase?
Heck, we do not generate invoices for these small sales. Perhaps someone knows about such online sales in FR?
