I store again the product’s name, description, and prices, because they are bound to change, but the invoice should remain the same always. That makes me wonder if i should do the same for seller’s and buyer’s data, but that should be a different commit. I’ve added the discount_rate domain because then i can test it independently of the invoice_product relation, moreover i am sure i will need it for simplified invoices too.
