In this self-invoicing guide, you will find step-by-step instructions on how to request an electronic invoice at checkout, what information is required, and how to receive it via email and through the SdI (Italian Tax Authority).
What (really) is self-invoicing on Mammarancia
At checkout, you will find the option ‘Would you like to receive an invoice?’ By selecting this option, you can enter your billing information to receive an electronic invoice in accordance with Italian law. On this page, we call it ‘self-invoicing’ as reported in the internal help section and in the site’s operating instructions.

1. Add the products to your cart and click on ‘Proceed to payment’.

2. Tick ‘Would you like to receive an invoice?’ to activate the billing fields.

3. Fill in the details carefully (see list below).

4. Confirm your order: accept the Terms and click on ‘Place order’. The invoice will be issued automatically after verification.
