It enables you to fill in many types of declarations (including AZ-O, CIT, IFT, NIP, OPL, ORD, PCC, PIT, POG, SD, UPL, US, VAT, VZM, WZP, WZS, ZAS and ZAW), send declarations electronically to the e-Declarations system and receive receipts, print on blank sheets of paper and ready forms, supervise bank transfer orders, create copies of the existing declarations, group and manage declarations according to various criteria, as well as store a list of entities. In addition, eDek allows you to use the Microsoft SQL Server 2005/2008 database, work in a network with multiple workstations, export and import forms in XML format (compliant with the e-Declarations system specification) and make copies of data security.
