Greek e-invoicing is becoming mandatory in 2020. The initial deadline to introduce this new obligation was January 2020, but the implementation date is expected to be postponed. This delay has not been confirmed yet. If approved, on July 1 will start a voluntary period that ends on October 1, 2020, when all businesses must issue e-invoices and report them to the tax authorities in real-time. By October 31, all historic invoices should have been issued and reported electronically.
Effective date: November 1, 2020
