E-invoicing in Slovakia: simple and in plain language

From 1 January 2027, every VAT payer must issue domestic invoices electronically via the Peppol network, and every taxable person and every Slovak legal entity, including non-VAT payers, must be able to receive them (§ 71(5) and § 85o of the VAT Act). We are a certified provider (digital postman, digitálny poštár). Here you will find guides for businesses (what it is, how to register and how to invoice) and, further down, the technical documentation (API) for developers.
