Thank you very much for answer.

I think yes will be better if  I clarify.

As from my understanding:* can't post l i n k- karma required o_0

Odoo under the hood provides solution for Invoice automation processing for countries from list of countries under section Applicability - Electronic invoicing (EDI)

If so that's really great.

But my country is not in the top list  and not in Fiscal localization packages

I was only able to find not-official Fiscal localization packages, but they  are available in App store.

Any thoughts and ideas in this situation?

still you haven't specified which country you are looking for !!

if this is not available by default, you have to build your own solution depending on guidelines provided by the govt. authority also if it is available in the store, you can consider buying that too

have a good day !!

Country - Moldova

Yes, as I see I need to build the solution.

How it can be done?

Any example of  Python code in Odoo?  

Our government provides just information on the paper like how it works and some piece of C# code.

as you are looking for reference, you can check the source code of existing integrations done in odoo which is listed here: https://www.odoo.com/documentation/16.0/applications/finance/accounting/customer_invoices/electronic_invoicing.html

you have to see how implementation done in one country and try mapping it with the paper's you received from govt side in your country

Yes, I had same thoughts.

But for me here is no available option:

Accounting ‣ Configuration ‣ Journals ‣ Customer Invoices ‣ Advanced Settings ‣ Electronic Invoicing

I tried to change country, but no chance - if I will change country it will impact on Journal, Invoices and on Accounting. I can't do that because company sells their products all day, I can't ruin Accounting
