Certification of Billing Software – Decree 340/2013, Portugal

In Portugal, Decree 340/2013 of November 22, 2013, aimed at strengthening measures against fraud and tax evasion, requires all Portuguese companies to use certified billing software. Companies that use proprietary billing software must obtain certification from the DGC (Direcção Geral de Contribuições e Impostos).


If your company needs to certify its billing program, ASSERTIO can help you complete the certification process quickly, providing both know-how and purpose-built software tools.
