I’m a microentrepreneur (BNC Prof Lib) above the TVA threshold with business clients in the EU. I’ve recently learned I should be declaring my sales on a monthly basis to the Douanes. I can’t figure out where to do this, however, as the website covers many different topics.
1. Do you have a link to share and maybe some advice on how to do this?
2. What about past invoices that I should have declared?
