Hi all, I'm writing because I'd like to implement what we call in Brazil Nota Fiscal. It's a kind of the American invoice but with a lot more information so the government can use it to control taxation and the transit of goods.
I'd like to ask you for some advices for what you believe to be the best practice to implement it. The first problem I think that I'll have to solve is that it will be necessary to add fields to Party, Person, and Product. Is there any way to do it without directly modifying respective entities? If possible I'd like to maintain it as decoupled as possible to be easily adoptable by users, without the need to patch or something alike. My first idea was to copy and change the invoice module. Do you think that's a good start? I appreciate any help and ideas you can give me. Thanks in advance, Luís Maranesi
