Try Fakturuj.siWhy do you need a digital postman?
Mandatory from 1 January 2027
From 1 January 2027, e-invoicing is mandatory for all VAT payers in Slovakia. Paper and PDF invoices will no longer suffice.
Delivery via Peppol
E-invoices are delivered through the international Peppol network. To send and receive, you need a certified Access Point — a digital postman.
Your gateway to the Peppol network
A digital postman is your access point to the Peppol network. It ensures sending and receiving e-invoices in compliance with the law.
Two types of solutions
Not every digital postman is the same. There are two basic approaches.
Standalone digital postman
- You need to connect it with an invoicing program
- You pay separately for the postman and the program
- Save settings
- Support split between two providers
Invoicing software with digital postman Recommended
- All in one — invoicing and digital postman
- Functions and use
- Overall cheaper solution
- One provider, one support
Verdict: If you don't have invoicing software yet, the all-in-one solution is the best value — you'll save time and money.

Frequently asked questions
Frequently Asked Questions about Digital Post Offices and e-invoicing 2027
What is a digital postman?
Digital Postman is a certified delivery service provider (Peppol Access Point) that handles the sending and receiving of electronic invoices via the Peppol network. It verifies the invoice format in accordance with the EN 16931 standard, delivers it securely to the recipient and submits the data to the Financial Administration.
Who is required to have a digital postman?
From 1 January 2027, under Act No. 385/2025 Z.z., every VAT payer in Slovakia must use a digital mail service to send and receive e-invoices for domestic B2B transactions. Paper and PDF invoices will no longer be acceptable.
How much does a digital postman cost?
Prices vary depending on the provider. Standalone digital mail services usually cost from €8 a month, and many offer some services free of charge. Fakturuj.si offers a complete solution — both invoicing software and a digital mail service — for €2 a month with no limit on the number of invoices.
Where can I find a list of certified digital postmen?
The official list of certified delivery service providers is maintained by the Financial Administration of the Slovak Republic and is updated on an ongoing basis. On this page, you will find an independent comparison of the best-known digital postal services, including their prices and features.
Do I need a digital postman as well as invoicing software?
Yes — a digital post office will deliver the invoice, but it won’t issue it. If you use a separate post office, you’ll also need invoicing software and will need to link the two services. An all-in-one solution (such as Fakturuj.si) includes both invoicing and the mail service, so you only need to set it up and pay for it once.
Since when has e-invoicing been compulsory?
Mandatory electronic invoicing in a structured XML format (EN 16931 / Peppol BIS) will apply to domestic B2B transactions involving VAT-registered businesses in Slovakia from 1 January 2027.
