Mandatory e-invoicing from 1 January 2027

Meet the legal obligation with us. No new software, no IT project.

The amendment to the VAT Act changes the way companies in Slovakia send each other invoices. A PDF by e-mail between VAT payers is no longer enough - the invoice has to go as a structured document through the Peppol network, and its data goes to the Financial Administration. The Bilvao app is ready for it today.

What the law says

  • VAT payers must both issue and receive invoices electronically for domestic B2B supplies.
  • Every entrepreneur and company based in Slovakia that a VAT payer supplies goods or services to must be able to receive an e-invoice - including sole traders and landlords.
  • The format is XML under the EN 16931 standard (UBL), delivered through the Peppol network by an accredited digital postman (access point provider).
  • An e-invoice must be issued and sent within 15 days of the supply. The data is reported to the Financial Administration, within 5 days for a received invoice.
  • Failure to meet the reporting obligation carries a fine of up to €10,000, and up to €100,000 if repeated.

How we handle it for you

  • Free, unlimited receipt of e-invoices from Peppol - you pay nothing to meet the obligation to receive them.
  • Sending to Peppol straight from the invoice - 10 a month on the FREE plan, 100 or 250 on the higher plans.
  • The right format, automatically - you fill in the invoice as before, and the app creates the XML under EN 16931 itself.
  • Bilvao accounting clients upload nothing - e-invoices received and issued through ePoštár (our digital postman) are in your books automatically.
  • Tax advisors and accountants behind you - if you are not sure whether the obligation applies to you, we will advise you.

    Transition period - the ideal time to activate Peppol and try it out for real.

  2. 1 January 2027

    Mandatory issuing and receiving of e-invoices within Slovakia (B2B and B2G).

  3. 1 July 2030

    Planned abolition of the VAT control statement - the Financial Administration will already have the data from e-invoices.

  4. 2030

    Gradual extension to cross-border invoices in the EU (the ViDA initiative).

This information is based on the amendment to the VAT Act passed in December 2025. It is not individual tax advice - we will gladly assess your specific situation.

Everything a business owner needs to see and do. One login.

Invoicing and e-invoices

The app works out VAT, totals and numbering.

Recurring invoices

Flat fees, rents and subscriptions are issued and sent automatically on the day you set.

You no longer have to think about monthly invoicing.

Foreign currencies

No typos in VAT IDs.

Documents, bank and accountant

Other documents in a second

E-invoices via ePoštár go into the books on their own. Drag receipts, contracts or paper invoices into the app, photograph them with your phone or forward them by e-mail - the app recognises the type and passes them to your accountant.

No more envelopes and boxes of receipts.

Bank connection via API

You connect your bank account to the app through API banking. Transactions load automatically and payments are matched to invoices on their own - no downloading statements.

You always know what has been paid and what hasn't.

Automatic payment reminders

When an invoice passes its due date and the payment hasn't arrived, the app sends the customer a payment reminder on its own. You don't have to chase anyone or write yourself reminders.

Money in your account sooner, without awkward phone calls.

Export for your accountant

Invoices in PDF, ISDOC, UBL and CSV - if you have your own accountant, they get everything in the format they need.

Suits external accountants too.

Documents

Questions and answers

What business owners ask us most often

Does mandatory e-invoicing from 1 January 2027 apply to me?

If you are a VAT payer, you must both issue and receive e-invoices for domestic B2B supplies. A business owner who is not a VAT payer must also be able to receive an e-invoice if a VAT payer supplies them with something. If you are not sure, get in touch - we will assess it for you.

What is Peppol, and what is a digital postman?

Peppol is a European network for the secure exchange of electronic invoices. Invoices in it are delivered by accredited providers - digital postmen. The Bilvao app is connected to the Peppol network, so you don't have to worry about delivery or the format.

How much will it cost me?

Invoicing and receiving e-invoices are free. On the FREE plan you send 10 e-invoices to Peppol a month. If you need more, the Invoicing plan costs €5.68 excl. VAT a month (100 e-invoices) and Invoicing PRO €14.63 excl. VAT (250 e-invoices). If you pay yearly, you get 2 months free.

Is the FREE plan really free for good?

Yes. It has no time limit, you don't need a credit card and you don't sign any contract that locks you in.

Do I have to keep my books with you?

No. You can use invoicing and e-invoices on their own and export invoices for your own accountant (PDF, ISDOC, UBL, CSV). On the PRO plan you can also give them guest access. The dashboard, cash flow and financial indicators are available to clients whose books we keep, because they are calculated directly from those books.

I'm a Bilvao client. Do I pay anything extra for the app?

No. The app and invoicing are part of your service, and issued and received e-invoices are automatically in your books. You log in with the same details as before.

As a Bilvao client, do I still have to upload anything?

Not invoices. If you receive and send e-invoices through our ePoštár, they are automatically in your books - you don't forward, download or scan anything. The only things you upload to the app are documents that didn't arrive electronically, such as receipts or contracts.

How does the bank connection work?

You connect your bank account to the app through API banking. Account transactions load automatically and the app matches them to issued and received invoices on its own. You don't have to download or upload statements.

Does the app send payment reminders on its own?

Yes. When an invoice passes its due date and the payment doesn't show up in your account, the app automatically sends the customer a payment reminder.

What if my customer isn't on Peppol yet?

You send them the invoice by e-mail as a PDF with a PAY by square QR code. If the customer cannot receive an e-invoice, the law considers your obligation fulfilled.

Do I have to report e-invoice data to the Financial Administration myself?

Data is reported to the Financial Administration through the digital postman. For a received e-invoice, the deadline is 5 days. For clients whose books we keep, we watch over the whole process.

How quickly do I have to issue an e-invoice?

Within 15 calendar days of the supply of the goods or service. This also applies to corrective invoices and credit notes.

Can I invoice in a foreign currency too?

Yes. The app fills in the ECB rate and converts the amounts automatically.

Can the app be connected to my online shop?

Yes, through the API and webhooks on the Invoicing PRO plan. A test API key for trying out the integration is available to you even on the FREE plan.

I have several companies. How does that work?

You add them all under one login and switch between them in the top bar. Each company has its own plan and invoice, and there is a 20% discount on the second and every further company.

Can I change or cancel my plan at any time?

Yes. You can switch to a higher plan immediately, with no waiting. There is no lock-in.

Is my data safe?

You control access by role, login is protected by two-factor authentication, data is encrypted and every change is recorded in an audit log.

Does the app work on mobile too?

Yes, the app runs in the browser on a computer, tablet or phone. So you can photograph a document and upload it straight from your phone.

E-invoicing becomes mandatory in a few months. With us, it's taken care of today.

Start for free - or entrust us with all your accounting and get the app along with it.
