Poland KSeF SAP – the National System of e-Invoices

Solution for automatic dispatch and receipt of structured e-Invoices

As of January 1, 2022, taxpayers can voluntarily use the National e-Invoice System (KSeF – Krajowy System e-Faktur), which greatly facilitates the settlement of business-to-business trade.

On 26 April 2024 the Ministry of Finance has announced new dates for the introduction of the National e-Invoicing System. According to the latest findings, the system will enter in two stages:

  • 1 February 2026 for entrepreneurs whose sales value exceeds PLN 200 million,
  • 1 April 2026 for all other entrepreneurs.

To support organizations and automate the provision and receipt of structured invoices, Apollogic experts have prepared a solution that integrates KSeF with SAP.

Our goal was to develop an intuitive solution that fits seamlessly into the organization's processes. The obligation to handle structured invoices is an additional responsibility for the finance and accounting departments. Therefore, it's crucial to provide teams with a solution to support them and minimize the time needed to carry out time-consuming activities.

Poland KSeF SAP – how does our solution work?

Apollogic’s solution integrates the SAP system using a cloud component to communicate with the KSeF API. The solution works in both SAP ECC and S/4HANA versions. When moving to a new system version, there is no requirement to invest in expensive customization – all you need is simple migration.

Sales invoices

Our solution enables browsing invoices prepared for sending in a dedicated cockpit, editing them, and creating a package of invoices for dispatch. Afterward, the user signs the package and sends it to the KSeF gateway via the middleware, and then receives information on the status of the shipment and an Official Receipt Certificate (UPO) with the necessary dates and reference numbers.

Purchase invoices

The user can download invoices issued in KSeF for a given recipient. Purchase invoices are saved temporarily in the SAP system with the option of viewing them in a dedicated cockpit. Once in the system, the invoice can be transferred for accounting, which can be done automatically or manually – depending on the process and customer requirements.
