Hello, could you advise me, who is the owner of Fiscal Localization for Slovakia available in Odoo settings ? Is it Odoo ? is there any possibilty to update it based on some observations. I see there a huge gap as Slovak legislature requires two additional fields to be printed on invoice. It is missing in Odoo. If you want to issue an invoice in odoo according to slovak legislature, you cannot operate on Odoo online as you require a 3rd party module from some local partner to be installed. Alternativly  you can add some fields with studio, but this is sometimes tricky for beginners.
