How do I set up a shipping address for my invoices? How do I send my invoice by email? How do I send an invoice or credit note to my customer? Can I follow the processing steps of an invoice once it is uploaded on the portal? What ways are there to submit invoices? Am I informed when my invoice is covered by the portal? I uploaded to the portal or sent by email an invoice. What if it does not appear on the portal? If I do not have a billing tool, can I use the portal to enter an invoice? Can I upload several files? Can I see all the processing events for my invoices? How am I notified that my invoice is rejected? When uploading invoices, how is the "reference" field used? Is an invoice sent by email visible immediately in the invoice tracking? When uploading an invoice, should the value of the "reference" field be unique? Is an invoice uploaded to the portal visible immediately in the invoice tracking? Can I send several invoices by email at the same time? My client allows me to send invoices by email or to enter or upload them on the portal. Do I have to choose? Why do I have to identify the issuing company when I’m filing or entering an invoice? Why have I received an email with the Subject “Issuing establishment cannot be identified"? How are the order and contract numbers checked? How many tax rates can I enter?
