How to create your first invoice on Flinvo

Step-by-step guide to issuing an electronic invoice in minutes — from client records to delivery to the Italian exchange system.

This guide takes you from signing up to sending your first invoice in under five minutes. No technical knowledge required: Flinvo fills in everything needed for electronic invoicing automatically.

Before you start

  • Fill in your tax details under Profile → Tax data (VAT number, tax code, tax regime).
  • Have at least one client on file, or create one on the fly while drafting the invoice.

The steps

  1. 1Go to Invoices from the side menu and click New invoice.
  2. 2Pick a client from the list, or create a new one with business name, VAT number or tax code.
  3. 3Fill in invoice data: number (auto-generated), date, due date and payment method.
  4. 4Add one or more lines with description, quantity, unit price and VAT rate.
  5. 5Review the preview and save. On standard tax regime, Flinvo generates the FatturaPA XML file ready for the exchange system.

You can duplicate an existing invoice to save time on recurring ones: open the invoice and pick Duplicate from the actions menu.

Delivery to the exchange system

On standard tax regime, after saving Flinvo lets you download the signed XML file or, with the integration enabled, send it directly to the exchange system. Invoice status (sent, delivered, rejected) is updated automatically.

Flat-rate taxpayers (forfettari) are not required to send invoices electronically below the revenue threshold set by law. Flinvo handles both cases: if you are on the flat regime, the invoice is saved as a PDF document you can email or print.
