From 1 January 2027 the way companies issue and receive invoices in Slovakia changes. A PDF sent by email will no longer be enough. Mandatory electronic invoicing, known as e-faktúra, is coming, and there is not much time left to prepare.
What exactly is changing
An e-invoice is not an ordinary PDF. It is a structured XML document based on the European standard EN 16931 that a computer can read and process automatically. Invoices will not travel by email but through the secure Peppol network, via certified intermediaries called digital postmen. Data from the invoices will also be reported to the tax authority.
Who is affected
The obligation covers domestic transactions between businesses (B2B) and between businesses and the public sector (B2G). Invoices to ordinary consumers (B2C) do not change for now. VAT payers who invoice domestic taxable persons will have to issue e-invoices. Other subjects, such as sole traders, professional firms or landlords, will also have to be able to receive e-invoices, even if they are not VAT payers.
Cross-border transactions within the EU are to follow later, planned from 2030.
What companies need to change
- Invoicing or accounting software. It must be able to create and read invoices in the required format, or connect to a digital postman.
- Choosing a provider. You need a certified delivery service provider from the Financial Administration list.
- Internal processes. You won't be able to simply "forward" invoices. You need to clarify who approves them, how they are archived and what happens when one is corrected.
- Archiving. Electronic invoices will have to be stored for the legal retention period.
Failing to meet the obligations can lead to fines, so it doesn't pay to leave everything to the last minute. Check the exact amounts and deadlines in the current legislation.
How automation can help
This is where well set up processes pay off. With automation you can:
- generate e-invoices directly from orders or from your ERP,
- automatically receive incoming invoices and match them to orders,
- send data to accounting without retyping,
- raise an alert when an invoice has incorrect data.
With a system like Odoo, e-invoicing can be built directly into your processes. And where you have older programs, RPA can connect the individual steps.
Preparation checklist
- Find out whether your current software is ready for e-invoices.
- Choose a digital postman.
- Test sending and receiving sample invoices.
- Update internal procedures and train your people.
- Check document archiving and backups.
