Slovak Invoice Bridge

Mandatory e-invoicing arrives in 2027. Be ready before it does.

From 1 January 2027, Slovak VAT payers must issue, receive and report invoices as structured electronic documents. Slovak Invoice Bridge makes your existing accounting or ERP system compliant β€” without ripping it out β€” and translates every technical rejection into language you can actually act on.

What is changing

A paper or PDF invoice will no longer be enough.

The change is bigger than emailing a PDF. Invoices must be structured data in a defined format, sent over a regulated network, and reported to the Financial Administration in real time. Two problems land on finance teams at once.

01

The format and the plumbing

Your invoice has to become an EN 16931 structured document, delivered over the Peppol network through a certified provider, with its data reported to the Financial Administration as it is issued.

  • Not every ERP will support the Slovak requirements in time
  • The delivery network is not something you connect to directly
  • Reporting happens at the moment of issue, not monthly
02

The cryptic rejections

When a structured invoice fails validation, the system answers with a code like BR-CO-10 β€” not a sentence. Someone has to work out what it means before the invoice can go out.

  • Business rule codes mean nothing to most finance staff
  • A stuck invoice is a delayed payment
  • The knowledge lives with one person who understands the standard

What Slovak Invoice Bridge does

A compliance layer over the system you already run.

You don't replace your accounting or ERP software. Slovak Invoice Bridge sits alongside it and takes care of everything the new regime requires β€” conversion, validation, delivery, reporting β€” and gives you back plain language whenever something needs your attention.

β†’

It handles the compliance

  • Conversion β€” your invoices become valid EN 16931 documents
  • Validation β€” checked against the business rules before they leave
  • Delivery β€” sent and received over Peppol via a certified provider
  • Reporting β€” data reported to the Financial Administration in real time
β†’

It stays out of your way

  • Keep your ERP β€” we integrate, we don't replace
  • Plain-language errors β€” every rejection explained and fixable
  • Multi-entity β€” several Slovak companies from one dashboard
  • Supported β€” set up, monitored and maintained by us
What the system says
[BR-S-08] For each different value of VAT category rate where the VAT category code is "Standard rated", the VAT category taxable amount shall equal the sum of Invoice line net amounts.
What Slovak Invoice Bridge tells you

Your 20% VAT base doesn't match the lines taxed at 20%. One line is missing its VAT rate β€” add it and the invoice will pass.

Who it's for

Made for Slovak companies in scope of the mandate.

The obligation applies to VAT payers established in Slovakia issuing domestic B2B and B2G invoices. If you're not sure whether you're in scope, tell us your situation and we'll assess it with you.

A strong fit

  • Slovak-resident VAT payer invoicing domestic B2B or B2G
  • Accounting or ERP system you want to keep
  • A group of several Slovak entities to manage centrally
  • Finance team that shouldn't have to decode validation errors

Probably not needed

  • Foreign company with no establishment in Slovakia
  • Private individuals who are not VAT payers
  • Only invoices that are VAT-exempt or simplified
  • An ERP whose vendor already delivers full Slovak compliance

Questions

The questions finance teams ask first.

Do we have to replace our accounting or ERP system?
No. Slovak Invoice Bridge is a layer that connects to the system you already use. Your team keeps working the way they do today; we handle conversion, validation, delivery and reporting behind the scenes.
Who exactly is obliged from 2027?
In short: VAT payers established in Slovakia, for domestic B2B and B2G invoices, from 1 January 2027 under Β§ 76a of the amended VAT Act. A phase covering non-VAT payers and cross-border invoices follows in 2030. If you're unsure about your case, tell us and we'll assess it.
What is EN 16931, and why does it matter?
EN 16931 is the European standard that defines what a structured electronic invoice must contain and how it's formatted. Slovakia's mandate is built on it. Getting an invoice to pass its business rules is exactly the work Slovak Invoice Bridge does for you.
What is Peppol and the certified provider?
Peppol is the network invoices travel over β€” you don't connect to it directly. Invoices are sent and received through a certified delivery provider (an access point). We handle that connection so you don't have to select and integrate one yourself.
What does the real-time reporting involve?
Invoice data must reach the Financial Administration at the moment the invoice is issued, not in a monthly batch. Slovak Invoice Bridge reports automatically as invoices go out, so there's no separate step for your team.
How long does it take to get ready?
A typical single-entity setup runs about four weeks: readiness check, connection, testing on your real invoices, then live. Custom ERPs and groups take longer. Because the deadline is fixed, starting well before the end of 2026 leaves room to test calmly.
We're a foreign-owned company in Slovakia β€” are we in scope?
If you invoice through a Slovak entity that is a VAT payer here, yes β€” that entity is a domestic VAT payer and falls under the mandate. A foreign company with only a Slovak VAT registration but no establishment is a different case; tell us the specifics and we'll confirm.
What if our invoices are VAT-exempt or simplified?
Certain exempt supplies and simplified invoices sit outside the structured-invoice obligation. We'll look at what you actually issue and tell you which invoices are in scope and which are not.

This page summarises the Slovak e-invoicing rules for orientation and is not legal or tax advice. The obligations follow Act 385/2025 Z. z. amending the VAT Act 222/2004 Z. z. (Β§ 76a). For a binding assessment of your specific situation, consult your tax adviser β€” or ask us and we'll assess it together.
