# No Greek e-invoicing provider yet: the free timologio fallback By Rotomal team · Updated 2026-11-03 · Part of [Τιμολόγια σε Τάξη](https://rotomal.com/en/ilektroniki-timologisi/) **Short answer:** If you have not signed with a provider yet, issue your B2B invoices through AADE's free timologio, an accepted channel for the obligation that has applied since 2 November 2026. If you will issue only through timologio, no declaration is needed; if you want to keep issuing the old way alongside until 31 January 2027, you file a declaration with a 2 November 2026 start yourself (per Taxheaven, by 12 November 2026). When you find a provider, you add it and it files its own declaration. ## The plan in three steps - Issue from timologio (https://mydata.aade.gr/timologio/) without delay, because the obligation has applied since 2 November 2026. For logging in with friendly codes or a Subscription Key, see the timologio login guide. - If you issue only there, file nothing. If you will also issue the old way until 31 January 2027, file the declaration yourself in myAADE (per Taxheaven, by 12 November 2026). - When you sign with a provider, add it; the provider files its own declaration and you may keep timologio as well. ## Why timologio fills the gap - It is free and has no usage limit, whatever the volume or size of the business. - It remains one of the two accepted channels after 1 February 2027. - It may be used in parallel with one or more providers. ## What timologio doesn't do It is a web app (plus myDATAapp on a phone) where you issue each invoice yourself. If your ERP must issue automatically, after 1 February 2027 it needs a provider connection, because direct ERP transmission stops. Until then, with a timely declaration, the ERP may send in parallel. ## How your accountant can help - Confirms which period you fall in (2023 gross revenue up to or above €1 million). - With an authorisation in myDATAusers, gets their own friendly codes and can issue for you. - Checks the declaration, if you need one, and the first invoices in myDATA. ## What Greek tax practitioners say On 16 October 2026 the Attica tax practitioners' union ΕΦΕΕΑ objected to dependence on private providers and to accountants acting as an informal, unpaid help desk. It asked to suspend the timetable, for a free public solution with open standards, and for at least 12 months without fines. As of 3 November 2026 we found no response that changes the dates; the obligation started on 2 November 2026. ## If you want us to handle it Τιμολόγια σε Τάξη sets up timologio with you on one video call (Declare & start, €29) and, once you choose a provider, connects your software with you (Full setup, €59). For accounting firms serving Greek clients, the €149 plan covers up to 5 VAT numbers and we take the calls with your clients, in Greek or English, so your firm doesn't become the help desk. ## FAQ ### Can I issue Greek e-invoices without a provider? Yes. AADE's timologio and myDATAapp are accepted channels, including after 1 February 2027. ### If I start with timologio, can I move to a provider later? Yes. You add the provider when you find one and it files its own declaration; you may keep timologio alongside. ### What if my software has no provider yet? With a timely declaration it may send in parallel until 31 January 2027. From 1 February 2027 it either connects to a provider or you issue from timologio. ### Will there be another extension? ΕΦΕΕΑ asked for a suspension on 16 October 2026, but as of 3 November 2026 we found no new announcement; the obligation started on 2 November 2026 as set. ### Is this tax advice? No. We summarise the announcements and Taxheaven's analysis. Your Greek accountant confirms your own case. ## Sources - Taxheaven: e-invoicing second period, question «I can't find a provider in time» (Greek) https://www.taxheaven.gr/news/74429/hlektronikh-timologhsh-b-periodos-analytiko-xronodiagramma-paradeigmata-erwthseis-kai-prostima - Taxheaven: new e-invoicing deadlines (30 September 2026, Greek) https://www.taxheaven.gr/news/74746/nees-prooesmies-gia-thn-hlektronikh-timologhsh-twn-epixeirhsewn-ths-deyterhs-periodoy-kai-th-b-fash-twn-pshfiakwn-parastatikwn-diakinhshs - Taxheaven: ΕΦΕΕΑ statement (16 October 2026, Greek) https://www.taxheaven.gr/news/74894/efeea-anakoinwsh-gia-thn-hlektronikh-timologhsh-kai-to-pshfiako-deltio-apostolhs - Naftemporiki: myDATAapp and authorisations in myDATAusers (28 January 2025, Greek) https://www.naftemporiki.gr/finance/economy/1896032/mydataapp-ekdosi-kai-apostoli-timologion-apodeixeon-apo-to-kinito/ - AADE: timologio login page https://mydata.aade.gr/timologio/ [Τιμολόγια σε Τάξη](https://rotomal.com/en/ilektroniki-timologisi/) does this for you.
