Download company data for invoice

Good morning everyone, I’m working on an application for managing a restaurant room
Forward this I would like to enter any invoices that the customer may ask me for but so far I have entered them manually item by item

Can any of you tell me if there is a system or an extension to be able to enter only the VAT number and obtain all the company data

So that this service becomes fast for me fast for the customer and very practical

To be fair, I am addressing an Italian audience as I am resident in Italy

If any of you have any ideas

GRAZIEEEEE…

can you tell me what you have to store and what to get. i’ll try to make a custom one

hello certainly

I would like the customer to give me his VAT number

And with the click of a button you can download the information needed to issue an invoice

Company name,
tax code,
CUU code “That is the unique code of the companies at least for Italy”,
address,
(email phone optional)

These are the data that I am sure Italy needs to issue an invoice
