Legislation · e-Invoicing

From January 2027
an invoice becomes data.

Mandatory electronic invoicing is the biggest change to Slovak business documents in years. For most companies it is an obligation. For prepared companies it is the first data source that looks the same at their suppliers as it does at home.

Until now an electronic invoice usually meant a PDF in an email — to a computer, an image somebody has to retype. The new obligation introduces a structured format that software understands on both sides.

01

One format

Invoices in structured XML following the European EN 16931 standard, in its Peppol BIS form.

02

Delivery via a provider

The invoice travels through a certified delivery service that validates its structure and confirms receipt.

03

Reporting to the tax authority

Invoice data is also submitted to the central infrastructure of the Slovak Financial Administration.

How much time
is actually left.

The transition window is shorter than it looks. Anyone who wants a calm 2027 should be testing during 2026.

2026Transition period

Voluntary participation in electronic invoicing testing. The right moment to check whether your software and your trading partners can handle a structured invoice.

1 January 2027Mandatory for VAT payers

Domestic invoices between VAT payers must be issued exclusively in the electronic structured format.

PenaltiesUp to €100,000

Breaching the electronic invoicing and reporting obligations carries fines of up to €10,000 for a first offence and up to €100,000 for repeated ones.

This reflects the framework as currently drafted. The legislation is still being refined — we track it and will tell you what applies on the day we meet.

An obligation that can
actually give you something.

Most companies will treat e-invoicing as compliance: buy a service, tick the box, forget about it. Meanwhile something appears that was never there before.

The first vendor-independent source

Until now, connecting to accounting looked different in every package. A structured invoice is identical at your company and at your trading partners — one solution works everywhere.

Payables visible on the day they arrive

An incoming invoice is machine-readable immediately, not once it has been posted. Your view of what the company owes moves weeks earlier.

A basis for cash flow

Combining structured invoices with bank movements produces a cash outlook that does not depend on a hand-maintained spreadsheet.

Less retyping

The data somebody currently copies from a PDF into a system arrives in machine form. The time freed up is a measurable saving.

We are not a delivery service.
We are the layer above it.

Sending and receiving invoices is handled by a certified provider. Our work starts where theirs ends — with what your company can see in that data.

01

We assess whether your current system can handle a structured invoice, and what you need from its vendor.

02

We feed incoming and outgoing invoices into a company-wide view of payables and receivables.

03

We combine them with the bank, so you see not only what has to be paid but what it will be paid from.

04

We set up alerts for documents that need a decision — approval, dispute or payment.
