Timologio helps Greek Shopify merchants collect invoicing details from customers during checkout. When a customer enters their 9-digit AFM (tax ID, ΑΦΜ), the app connects to the official AADE/GSIS government database in real time, validates the number, and auto-fills the company name, tax office, and address. All data is saved directly to the Shopify order as clean Greek labels. A professional invoice document with fully exportable CSV and XML files is provided for every order with invoice.
