Billing
At checkout, after entering your shipping information and choosing your preferred payment method, you will find a box to check that says "Do you need an invoice?"
By checking it, some fields will appear that you can fill in with the company name, address, VAT number and any SDI code. Alternatively, you can write to shop@hiro.design sending all your data. Remember that, according to Italian tax legislation, it is not permitted to issue an invoice after the twelfth day from the date of purchase.
