Prothesmia

**Prothesmia** — a SaaS deadline tracker for Greek businesses and the accountants/freelancers who serve them. The problem: Greek tax and business obligations are scattered across ΑΑΔΕ, ΕΦΚΑ, ΓΕΜΗ and myDATA, each with its own calendar and its own penalties for missing a date. Nobody keeps one reliable list. The product: a single dashboard where a business enters its profile (legal form, VAT regime, employees, ΓΕΜΗ obligations) and gets a personalized calendar of every upcoming filing and payment — VAT returns, ΕΦΚΑ contributions, ΓΕΜΗ annual filings, myDATA submissions, payroll deadlines. Reminders go out by email/push at configurable intervals ahead of each date, with the relevant form and portal link attached. Multi-client view for accountants managing many entities. Model: subscription, tiered by number of entities tracked. Solo build, Greek market first.
