DHApp is a free Android application developed by Zucchetti that allows you to issue invoices and credit notes and send them to the Italian Revenue Agency's Interchange System (SdI) through Digital Hub Zucchetti. With this app, you can manage your clients, articles, and payments all in one place. You can also work offline or without an internet connection and connect only for sending and receiving documents.

If you have purchased electronic invoice packages or use a Zucchetti accountant, you can use Digital Hub Zucchetti credentials to create and send your documents in the format requested by the Italian Revenue Agency (XML file), monitor the sending and receiving phase of the responses sent by SdI, and view and download the electronic documents sent to you by your suppliers through the Interchange System and even convert them into PDF format.

DHApp is a free app that allows you to manage and simplify the invoicing process and work on-the-go with considerable time savings.
