SPED, which is an acronym used to represent the “Public Digital Bookkeeping System”, started with three major projects: • EFD – DIGITAL TAX BOOKKEEPING • ECD – DIGITAL ACCOUNTING BOOKKEEPING • NF-E – ELECTRONIC INVOICE. At companies, it simplifies and facilitates the delivery of the necessary documentation to Tax Authorities because it uses a digital medium that is currently easily accessible to everyone and, in addition, eliminates the need to maintain these documents on paper and, for the government, facilitates inspection and reduces the bureaucracy for delivery of those documents.
