Michael Siaterlis

Michael Siaterlis has worked in IT since 1990. He started as a PC technician and software trainer, worked at the Apple Central Service Centre in Greece, managed the Greek branch of Giesecke & Devrient, was a Team Leader at Apple and at AlbaSoft, and IT Manager at Classique Furnishing. MS-Logic started in parallel in 2003 and has run as an independent business since 2010.

His experience is hands-on. Long before myDATA, he connected an e-shop to his commercial program, WinWay, so that warehouse stock was updated from orders. In 2020 he connected WinWay to myDATA, the Greek tax authority's platform, and later to a fiscal device program and a portable card terminal for a client who collected payment at the door: the document was printed only after every step had succeeded. Today LogicInvoice does the same job, through a certified electronic invoicing provider.

He designs and builds the MS-Logic products, such as LogicInvoice, Ekkremés, MS-Finance, MS-Tools, MS-Consent and MS-Analytics. He runs the server that hosts more than 120 domains, and writes the articles on this site about electronic invoicing, SEO, GEO, security and e-commerce. He is also a published author of books in Greek, and one of his novels is available in English translation.
