ru-einvoiceSource-cited draft Use this skill whenever asked about Russian electronic invoicing or digital tax reporting for a self-employed person or small business: the VAT invoice (счёт-фактура), the universal transfer document (УПД), electronic document exchange (ЭДО) and when e-invoices are mandatory, the goods traceability system (национальная система прослеживаемости товаров), online cash registers (ККТ / онлайн-касса) transmitting via ОФД to ФНС, product labelling («Честный знак» / маркировка), the electronically filed VAT return, and what a самозанятый (НПД), an ИП on УСН, and an ИП/ООО on ОСНО must each do. Trigger on phrases like "счёт-фактура", "УПД", "ЭДО Russia", "online cash register Russia", "ККТ", "онлайн-касса", "ОФД", "прослеживаемость", "маркировка", "Честный знак", "e-invoicing Russia", or any question about Russian digital invoicing or fiscal reporting. Always read this skill before advising on Russian e-invoicing or fiscal reporting.
