You issue an invoice in the system
Asystio generates an invoice and automatically sends it to KSeF in the required XML format. You see a normal invoice - the system does the rest.
Mandatory from 2026
KSeF is coming. Is your company ready?
The National e-Invoice System becomes mandatory for Polish companies in stages. Asystio helps organize invoices, data, permissions, token or KSeF certificate in one workflow.
Calendar KSeF - key dates
2022
KSeF launched as a voluntary pilot scheme. Companies can test e-invoicing without obligation.

1 April 2026
The obligation expanded to other companies, except the smallest businesses covered by the deferral.

The smallest businesses join KSeF if their monthly invoice-documented sales do not exceed PLN 10,000.
What is KSeF?
The National e-Invoice System is a government platform for issuing, storing and sharing structured invoices in the XML format.

KSeF assigns a reference number
Each invoice receives a unique number KSeF. From that moment on, it is legally valid and available to both parties - the seller and the buyer.
3
Invoice available immediately
The buyer can download the invoice from KSeF at any time. No more lost emails, scans or PDFs in the 'To be processed' folder.
What does the integration of KSeF in Asystio give you?
Automatic listing
The invoice is generated after a visit, sale or at the end of the month. No manual work - click 'Submit' and you're done.
KSeF compliance support
Workflow prepared for Ministry of Finance format and validation requirements. Before submission, the system helps reduce data errors.
Instant confirmation
The reference number KSeF appears in the system in a few seconds. You know immediately that the invoice has been received.
Invoice archive
All invoices stored in the cloud and in KSeF. Available 24/7, no risk of loss. Compliant with archiving requirements.
Integration with finance
KSeF invoices connected to the financial module. Automatic settlements, VAT reports, revenue forecast - all in one.
Correction and advance invoices
Corrections, proforma, advance payments - all types of invoices handled automatically and sent to KSeF in accordance with the regulations.
KSeF token and certificate
How does a client get KSeF access?
In practice, a salon or service company does not simply buy a key. First it confirms identity and permissions in KSeF, then generates a token or requests a KSeF certificate for integration. It is an organizational, technical and security process at the same time.
Source status: 24 May 2026. Tokens can be used in 2026; according to KSeF information, from 1 January 2027 certificates remain the target method. Confirm the scope with accounting or a tax advisor before production rollout.
1. Choose the admin and NIP context
KSeF authorization works in the context of a specific Polish tax ID. The owner, board member, ZAW-FA representative or accounting office needs the right permissions.
2. Sign in to the KSeF 2.0 Taxpayer App
Authenticate as the taxpayer or authorized person, for example with a trusted profile, qualified signature or qualified electronic seal.
3. In 2026 use a token or KSeF certificate
Tokens can support commercial app automation in 2026. KSeF certificates are the target authentication method after the transition period.
4. Store the secret securely and limit permissions
Treat the token or certificate like banking credentials. Do not send it by email or chat, and grant only the permissions your workflow really needs.
5. Test invoice, UPO and correction flow
Before production use, test contractor data, issuing, submission, KSeF number, official receipt, correction and accounting access.
