Invoice statuses and UPO

An invoice is issued in the “Invoices → New invoice” view: after filling in the details (the counterparty’s details are pulled in automatically by NIP), the document is sent to KSeF. Once accepted, it’s assigned a KSeF number and a UPO is generated.

Draft → sent → accepted (KSeF number assigned), or rejected with a stated reason. The rejection reason is visible after opening the invoice.

The Official Confirmation of Receipt — confirmation that KSeF accepted the invoice. Atestio retrieves it automatically and makes it available with the invoice document.
