KSeF Statuses

Overview

Every invoice sent to KSeF passes through a sequence of statuses as it is processed. Biurko displays the current status in real time, so you always know exactly where an invoice stands.

Transmission Lifecycle

• Pending — the invoice has been queued for sending.
• Sending — transmission to KSeF is in progress.
• Accepted — KSeF has accepted the invoice and assigned it a unique KSeF number.
• Rejected — the invoice failed validation and requires correction before it can be resent.

KSeF Number and UPO

Once an invoice is accepted, it receives a unique KSeF number, and the system issues a UPO (Urzędowe Poświadczenie Odbioru — Official Receipt Confirmation). The UPO is the official proof that the invoice was submitted; Biurko stores it together with the invoice for your records.
