Slovakia: Financial Administration Publishes Guidance on Choosing a Certified Delivery Service Provider for eFaktúra

On 6 November 2026, the Slovak Financial Administration published practical guidance to help businesses, sole traders, municipalities and non-profit organisations select a “digital postman” (certified delivery service provider) and conclude a service contract.

Electronic invoicing will be introduced in Slovakia from 1 January 2027. eInvoices will be sent and received through certified digital postmen, whose services can be used directly or through their intermediaries. According to the Financial Administration, almost 100 certified providers are already available in Slovakia.

The guidance, published in the eFaktúra section of the Financial Administration portal, recommends checking the following before signing a contract:

• Service provider: which company actually sends and receives the eInvoices, who the contracting party is, and who is responsible for data protection.
• Price: total costs, including additional fees, time limits on free or discounted offers, and prices after they end.
• Scope of services: receiving, issuing and sending invoices, connection to accounting software, and access for other users such as an external accountant.
• Archiving: document retention conditions, availability period and download options.
• Termination: notice period, termination fees and the procedure for switching to a new provider.

The guidance also explains the difference between a certified digital postman and its intermediary. Certified providers must meet technical, organisational and security requirements, compliance is supervised, and serious breaches may lead to withdrawal of the authorisation to provide the delivery service.

The list of certified digital postmen and their intermediaries is available in the Financial Administration’s provider selection application.
