No KSeF notification does not mean no invoice

KSeF does not send automatic system notifications about new invoices. No email or alert is therefore not proof that a new invoice is unavailable.

How software learns about invoices

The taxpayer's software obtains information about available invoices by querying KSeF. This differs from a notification sent by KSeF itself. Source: Ministry handbook §6.4.

An alert may come from software

An accounting software provider may implement its own notifications. The handbook allows this at individual software level; it does not mean every program has it or operates it automatically without configuration. It is not a guarantee of a specific Ogar feature.

Ask the provider or accounting office whether the software checks new documents, where it displays them, whether alerts exist and who receives them. This is a practical question list, not a prescribed checking frequency. If no alert arrives, check the invoice list rather than drawing conclusions from your email inbox alone.

FAQ

Does KSeF email you about a new invoice?

It sends no automatic system notifications. Such a notification may be a separate feature of particular software.

Can software send its own alert?

Yes, a provider may offer a local notification feature. Check its availability and settings in that program.

Does no alert prove there is no invoice?

No. Checking available invoices and receiving an alert are separate things.
