The KSeF Simplified and the National System of e-Inovices
Key dates:
Why is it important to prepare for change now?
-
Time to comply with the new regulations
-
The introduction of the obligation to issue structured invoices to KSeF brings with it many changes relating to processes, organization and systems. To prepare your organization to implement the right solutions and to identify in advance potential impediments that will affect the length of your project, it’s a good idea to start now.
-
Need to make changes to SAP
-
The introduction of new regulations forces businesses to validate existing processes in SAP, and in many cases to make changes in selected modules.
-
Ability to test tools and processes
-
Before sending e-invoices becomes mandatory, businesses should take the opportunity to test the KSeF system and its integration with internal applications. This will allow you to develop optimal solutions that are also responsive to the new regulations.
-
Faster VAT and other benefits
-
The implementation of e-invoicing is associated with potential benefits for taxpayers, including: VAT refund shortened from 60 to 40 days, improved cash flow and faster circulation of documents, easier and continuous access to e-invoices 24/7, and no need for archiving or error correction thanks to a single fixed invoice template.

Modern interface and flexibility
The KSeF Simplified solution has an easy-to-use interface that does not require advanced training, only basic knowledge of the SAP system. Users can also customize the tool to meet individual needs and processes established within the organization.
