The "E-Invoices (EFX)" functionality is used to view electronic invoices issued for the NFZ. After selecting this functionality there is displayed a list of contracts with the NFZ. Agreements are divided into years (agreements with consecutive years are available in separate tabs). Below the list of contracts, a list of issued invoices unrelated to any contract is displayed (each such document has a "Preview" button that allows you to preview a PDF file with the invoice printout and for users with appropriate permissions also the "Delete" button that allows you to delete a document issued by mistake or incorrectly).

At each agreement there is the "Select" button, which when pressed displays a list of template of bills loaded into the jHIS system for the particular contract and a list of documents issued without the bill template (each such document has a "Preview" button that allows you to preview the PDF file with the invoice printout and for users with appropriate permissions also the "Delete" button that allows you to delete a document issued by mistake or incorrectly).

At each template there is the "Documents" button, which when pressed displays a list of electronic invoices issued based on the template of bill. For each document for which a printout was generated in the form of a PDF file, the "Preview" button is displayed, enabling the preview of a PDF file with an invoice printout and for users with appropriate permissions also the "Delete" button that allows you to delete a document issued by mistake or incorrectly.
