E-invoice from 2027? We'll prepare you in time - and without stress.

From January 1, 2027, the way businesses send invoices is changing. At Numiron, we'll take care of it for you – you'll continue invoicing as you're used to.

What is actually changing

Until now, a PDF or paper invoice has been sufficient. From January 1, 2027, VAT payers will send invoices to Slovak companies electronically—in a unified format that systems will deliver to each other and then automatically read. Paper and PDF in emails are ending. At least for VAT payers.

Does this concern me too?

As a VAT payer → From January 1, 2027, you will have to issue and receive e-invoices.

I am not a VAT payer → From January 1, 2027, you must be able to receive e-invoices. You will issue them from July 1, 2030.

Not sure? We'll guide you step by step.

How Numiron can help you

You invoice as before. Numiron invoices on your behalf in the background, sending them to the Peppol system like a digital postman. It also retrieves and delivers your received invoices from the system and uploads them to Numiron. You will no longer have to manually upload received invoices from non-VAT payers.

We take care of security, technical implementation, and legislation for you. Numiron is the only billing system and accounting software in Slovakia that is a member of the Slovak Chamber of Tax Advisors.

Digital Mail Carrier

To ensure that an e-invoice reaches the other party and the data is reported to the Financial Administration, a certified service – the „digital postman“ – is used. Numiron will be your digital postman: it will securely send and receive e-invoices on your behalf. You do not need any additional service.

You won't have to deal with anything at the last minute. We will let you know in time and guide you through the change.
