Your company and your customers and suppliers all at once, on one screen. From 1 January 2027, VAT payers must send invoices to Slovak companies as e-invoices through the Peppol network, and every company must be able to receive them. Free of charge, we do not store the IČO you enter.
For each company we verify five things at once:
| Customers and suppliers | Company ID | Peppol network | VAT | What follows from it |
|---|
From 2027, e-invoices are delivered through the European Peppol network. A Slovak company has an address in it in the form 0245:DIČ. We query the network directory in the same way as a delivery service does when sending an invoice. If we find the company, we also show which service receives its invoices.
Whether a company must issue e-invoices depends on whether it is a VAT payer. We check this in the list of the Financial Administration of the Slovak Republic by IČO and in the European VIES register. For a member of a VAT group, we also find the group's IČ DPH.
We take the name and registered office from the Register of Legal Entities, and the DIČ from the lists of the Financial Administration or from the Register of Financial Statements. If the company has ceased to exist, we will alert you. Do not send e-invoices to such a customer any more.
The obligation to issue e-invoices is narrower than is often written. The obligation to receive them is, on the contrary, broader. The first phase applies from 1 January 2027 to 30 June 2030.
| Situation | What happens |
|---|---|
| A Slovak VAT payer invoices a Slovak company, sole trader, municipality or association | Must issue an e-invoice |
| A non-VAT payer, municipality or association buys from a VAT payer | Must be able to receive an e-invoice |
| A non-VAT payer issues an invoice to a company | Does not have to issue an e-invoice |
| Sale to a private individual, receipt from a cash register up to €400, document up to €100 | Doesn't apply |
| Supply exempt from tax | Doesn't apply |
| Foreign company with a Slovak IČ DPH (registration under § 5) | It does not apply to her until the end of June 2030 |
| Invoice to another EU country | Only the listed cases, and only from July 2030 |
An e-invoice goes through a delivery service registered with the Financial Administration. The same service also sends the invoice data to the tax office. For failing to issue a mandatory e-invoice, the fine is from 100 to 10 000 €. For failing to report data, the fine is up to 10 000 €, and up to 100 000 € for repeat offences. You will find details in the article E-invoicing from 2027: a PDF by e-mail will no longer be enough.
We register matu.sk clients on the Peppol network and set up receiving of e-invoices for them. You issue e-invoices in the client zone or in our phone app. Received invoices arrive in the zone and we book them straight away. You do not need to look for another program or a delivery service.
A Peppol ID is a company's address on the Peppol network, much like an e-mail address for mail. A Slovak company has it in the form 0245:DIČ, for example 0245:2120466810. The number 0245 denotes a Slovak DIČ. The address is registered for you by the delivery service you choose.
You do not have to issue e-invoices from 1 January 2027. However, you must be able to receive an e-invoice from a supplier who is a VAT payer, so you do need to be on the Peppol network. You do not report data from received invoices to the tax authority.
By 1 January 2027, choose a delivery service and ask it to register you on the Peppol network. If you already have a service, check that it registered you under the correct DIČ. If a customer is missing from the network, warn them in good time. From January you will have no way to deliver an e-invoice to them.
One of the public registers or the Peppol network directory did not respond just now. In that case we would rather write nothing than claim that the company is not on the network. Try again in a few minutes. If the company has no DIČ in any public list, there is nothing to query the Peppol network with.
No. A list of customers could reveal who you do business with, so the IČO is not stored anywhere or written to server logs. We only count how many companies were checked from one connection so that the page cannot be flooded.
It is free and requires no registration. From one connection you can check 150 companies per hour and 400 per day. For an ordinary company that is enough to check all its customers. The limit protects the public registers and the network directory so that they do not block us because of overload.
A Peppol network registration is visible as soon as the delivery service makes it. The Financial Administration updates the list of VAT payers once a day. That is why we also check a fresh registration in the European VIES register.
No, not between Slovak VAT payers. The invoice must be a data file according to the EN 16931 standard and must go through a delivery service. You can send a PDF in addition as an attachment, but on its own it does not meet the obligation. If you only need an ordinary invoice, for example for a private individual, you can use our online invoice.
The check is indicative. It is based on public registers and the Peppol network directory at the time of the check and does not replace an assessment of your specific situation by an accountant or tax adviser. Company data comes from the Statistical Office of the Slovak Republic (Register of Legal Entities), the Financial Administration of the Slovak Republic (open data), the Register of Financial Statements, the European Commission (VIES) and the Peppol network directory.
We process the conversation and the data you enter in line with our privacy policy. We send the chat transcript to the accountant and, once you confirm your address, to you as well.
