It depends on the case. For NF-e (electronic invoice for products), a digital certificate is usually required. It is an electronic signature that proves who you are. For NFS-e (electronic service invoice) on the national portal, however, MEI and small businesses can use just a gov.br account (silver or gold level), with no certificate. Those who use their own system (ERP) still need the certificate. TF Assessor reviews your case and, if needed, issues your certificate 100% online.
