Main assumptions of the KSeF project
- The draft act is to introduce the possibility of issuing structured invoices, that is in line with the technical guidelines of the Ministry;
- The scope of data reported under the new form of invoice includes many additional elements, other than the standard invoice;
- The KSeF is to structure and provide the real-time control over the invoicing process;
- The structured invoice is to be one of the acceptable forms of documenting transaction in the optional period and from 2023 the only possible form.
