Received invoices from KSeF

Since 1 February 2026, KSeF delivers invoices issued through KSeF to the buyer. Fiskora can get your purchase invoices from KSeF. You do not need to sign in to the official app to find them.

What you need

A connected KSeF certificate. See “Connect your KSeF certificate”.
An invoice that your supplier issued through KSeF to your NIP.

Where to find them

Sign in to Fiskora.
Open the section for received invoices or purchase invoices.
Open an invoice to see its details and to download it.

The labels in the app can be a little different from this description.

How they get there

Fiskora gets purchase invoices from KSeF through your connection. A new invoice from a supplier can take some time to show. If you expect an invoice and it is not there, wait and check again.

What you can do with them

Read the invoice details.
Download a copy.
Export the invoices, for example in the ZIP export, so that your accountant has them.
Let your accountant see them through the free read-only login.

What if a supplier sent me a PDF by email?

For suppliers who must use KSeF, the invoice in KSeF is the official invoice. The PDF is only a copy for your convenience. If you have a PDF but no invoice in KSeF, ask the supplier if they issued the invoice and when. Ask your accountant if a PDF is acceptable in place of the KSeF invoice. The answer depends on the situation of the supplier.

What Fiskora does not do

Fiskora shows and exports purchase invoices. It is not bookkeeping software. It does not record costs and it does not file VAT returns. Your accountant does these tasks.

Troubleshooting

Nothing appears. Make sure that the KSeF connection works and that the certificate is not expired.
An expected invoice is missing. The supplier can use a wrong NIP, or the supplier did not issue the invoice yet. Ask the supplier.
