06 / INVOICES AND KSEF

Invoices and KSeF. VAT and corrective invoices sent to KSeF, with UPO and offline mode.

Invoices per client and matter: an FA(3) file validated against the Ministry of Finance schema, sent to KSeF, with the KSeF number and UPO retrieved.

HOW IT WORKS

Invoice and KSeF in a single step.

Now that KSeF is mandatory, an invoice issued outside the system means an extra step, a risk of rejection and manual checks on whether the document was accepted.

CHALLENGEWORKFLOWRESULT

01 / DRAFT

Prepare the invoice

Client, matter, line items, VAT rates from 23% to “zw” and “np”. Amounts calculated exactly, to the grosz.

Each invoice validated against the schema before submission.
02 / ISSUE

03 / CONFIRMATION

Receive the KSeF number and UPO

REAL-WORLD EXAMPLE

The KSeF status of every invoice is visible on the list, and the firm learns of any rejection straight away.

A lawyer issues an invoice for a matter. The seller's and buyer's details are fixed at the moment of issue, the invoice joins the KSeF queue, and once it is accepted the KSeF number and UPO appear on the list.
