Frequently asked questions about e-invoicing via Peppol

There is no catch, and yes, we are aware the price sounds unbelievable. We pushed it to the minimum deliberately, because that is our goal: to be the cheapest provider while keeping maximum quality.

It works because we automate everything that can be automated. When you select us on the Financial Administration portal, company verification, account setup, registration in the central Slovak registry and in the Peppol network, notification setup and reporting to the Financial Administration all happen without human intervention. Invoices are delivered, validated and confirmed with delivery receipts on their own. One customer therefore costs us practically nothing extra, and that is exactly how much cheaper we can afford to be.

On top of that, we do not carry the things that push the price up elsewhere: no corporate offices, no call centre, no commissions for sales reps. We operate our own Peppol Access Point, so we do not pay a margin to anyone above us. We host data in the cloud in the European Union and keep operations as lean as possible.

So this is not just a claim: our price list is entirely public (most of the market does not publish prices), and we give a price guarantee: if you find a cheaper comparable offer, we will match it, for as long as you use the service. With us, you simply never overpay.

No, cheap and low-quality are not the same thing. We are a certified provider (ID EFSK000031) with our own Peppol Access Point (Seat ID PSK001128) with a direct connection to the network. We have passed all 19 OpenPeppol conformance tests, and our operations run on a production certificate on the live network. Every invoice goes through EN 16931 and Peppol BIS Billing 3.0 validation, and you get a delivery receipt for every invoice sent.

You do not have to take our word for it: download our provider certificate (PDF) or check our uptime on the public service status page, where we publish measured availability for the last 90 days.

Yes – ISO/IEC 27001:2022 certification is under way. The certification body is SKQS, s. r. o., Žilina, accredited by the Slovak National Accreditation Service (SNAS); we selected it in September 2026 and will obtain the certificate in line with the Peppol timeline that mandates it for every provider in the network from 1 July 2027. It is a shared obligation for the whole market, not something we are missing compared to it.

Independently of that, we are already a certified provider, EFSK000031, with our own Peppol Access Point, and we run operations under the same rules: data in the EU, an audit trail for every operation, uptime monitoring and validation of every document.

The Verteco brand has been on the market since 2018; the digital postman service is operated by Verteco digital services, s. r. o. (company ID 53412834, Žilina), which holds the EFSK000031 certification and its own production Peppol certificate. The company has been entered in the Commercial Register of the Žilina District Court since 5 November 2020 (trading as Zechmeister, s. r. o. until 11 May 2022); it has held the Slovak Financial Administration accreditation since 26 May 2026 and has operated on the production Peppol network since 8 July 2026. We build on long-term relationships, which is why we offer the price guarantee and why we keep prices low permanently, not as a temporary promotion.

And most importantly: you are not tied to us in any way. Peppol is an open standard, you can switch providers at any time, and when you leave we hand over every document as both original XML and a CSV export, and delete our copies on request. No lock-in, no exit fees, no data hostage-taking.

The prices in our price list apply from 1 January 2027, and it is the price the whole model is built on, not a bait-and-switch promotion that doubles after a year. Most of the market today offers “free until the end of 2026”; we publish straight away the price that will apply afterwards.

The backstop is our price guarantee: if anyone offers you a cheaper comparable offer, we will match it, at any point during your use of the service, not just at sign-up. A comparable offer is the permanent public price of a certified provider for a standalone digital-postman service of the same scope; time-limited promotions and prices conditional on buying another product (for example an accounting-software licence) do not count as comparable.

We host data in the cloud in the European Union (Frankfurt); invoices never leave the EU. Storage is governed by the Data archive setting on the company detail page: for new companies it is on by default (included in the €2/mo per company service), we keep the originals (XML) of received and issued invoices for as long as you are with us (1 GB included), and when the relationship ends the choice is yours: we hand over the documents, delete our copies, or both. A company that switches the archive off receives for free; its document content is then deleted 14 days after arrival and you keep the originals yourself.

Only your account and any accounts you invite have access to the documents. We can only make specific changes (access, transferring a company) from a verified account that selected us on the Financial Administration portal, which is why all support runs through the logged-in account. Details in our privacy policy.

Yes, and you decide, via the Data archive setting on the company detail page. For new companies the archive is on by default: we keep the original received and issued invoices safely in the EU for as long as you are with us (1 GB included) as part of the €2/mo per company service, set separately for received and for sent documents, and available in the portal at any time. If you only want to receive invoices for free, switch the archive off: document content is then automatically deleted 14 days after arrival. With the archive off, the statutory 10-year archiving duty (§ 76 of the Slovak VAT Act) rests with you: originals arrive by e-mail or webhook and can be downloaded for 14 days. Details: data archive.

Peppol is an international network for the secure, standardised exchange of electronic documents (mainly invoices) between businesses. From 1 January 2027, e-invoicing via Peppol will be mandatory for B2B transactions in Slovakia. Our portal lets you receive and send e-invoices without building your own technical integration.

Mandatory electronic invoicing for domestic B2B transactions between taxable persons based in Slovakia starts on 1 January 2027. The exact scope and deadline for a specific entity may differ; we recommend checking with your accountant. Get ready ahead of time: until that date, the portal is free for everyone.

The law distinguishes two obligations. From 1 January 2027, VAT payers must issue e-invoices via Peppol for domestic B2B transactions. Every taxable person based in Slovakia, LLCs and sole traders alike, including businesses not registered for VAT, must be able to receive e-invoices, regardless of company size. Check the exact scope for your entity with your accountant.

Breaching e-invoicing obligations can bring a fine of up to €10,000 from 2027, and up to €100,000 for a repeat breach (Act No. 385/2025 Coll.). 2026 is a preparation period with no sanctions, and an obvious mistake you correct promptly is not fined. The safest route is to get set up and test the whole process already in 2026, for free. Details in the article Fines and penalties for e-invoicing (Slovak).

Yes. One account handles multiple companies (LLCs, sole traders) and clients, which accountants especially appreciate. The €2/mo fee is charged for every company ID that sent an invoice in the month or had the Data archive on (the default for new companies); a company ID with the archive off that only receives is free.

Peppol is not a portal. It is an international network (infrastructure) that businesses use to exchange structured documents through certified Access Points. Our portal is the interface to our certified Access Point (PSK001128): through it, you connect to the Peppol network without building your own integration.

A PDF is essentially an image meant for a human; the recipient has to retype it or run OCR on it. A Peppol e-invoice is a structured data document (EN 16931) that the recipient system processes automatically, and it satisfies the legal e-invoicing obligation for domestic B2B transactions from 1 January 2027. A regular PDF invoice does not satisfy this obligation.

No. A recipient who has not chosen a provider has no address in the Peppol network, so nobody can deliver to them; the send stops at the participant-register (SML) check. Per the Slovak Financial Administration (FAQ 9/DPH/2025/IM, example 9) the sender's duty is met by handing the invoice to the delivery service and the report to the Financial Administration goes out regardless of delivery; under § 85o(11) of the VAT Act (from 1 Jan 2027) the reporting duty is deemed met at hand-over, and the duty to be able to receive e-invoices lies with the recipient (§ 71(5)). We keep such an invoice among your sent invoices as "not delivered: recipient not in the Peppol network", the FS report goes out and no rejection e-mail is sent. Send it to the recipient by e-mail or post for now (per FS this only re-provides the same invoice and does not affect VAT deduction) and resend it via Peppol once they register. Check a recipient beforehand on company check. In 2026 sending via Peppol is voluntary, so neither you nor the recipient is in breach.

No. The portal is a pure delivery service into the Peppol network; invoices for recipients outside the network cannot be sent or printed through it. That is why we work with resellers whose invoicing tools run on our infrastructure: you create, print or e-mail the invoice there, and recipients on the Peppol network receive it electronically. The list is on our resellers (in Slovak).

It is not. The European e-invoice format (EN 16931 / Peppol BIS 3.0) has no separate field for the Slovak tax number (DIČ), so the seller identifier travels in the tax identifier field as SK + DIČ. For a non-VAT payer that is not a claim to hold a VAT ID; VAT status is expressed by the VAT category on the lines (exempt, 0 %). To avoid confusion in the visualisation as well, untick “We are VAT registered” in the company detail: the portal then shows “DIČ” instead of “VAT ID” when sending, in the detail and on the PDF. PDFs and previews are only a visualisation; the e-invoice is the XML itself.

Register with your e-mail, add your company (company ID and tax ID) and have the statutory representative confirm Verteco as provider on the Financial Administration portal (eID or PFS login). That registers the company for receiving in the central SMP (unless another provider already holds it) and gives us the verification token we need before sending. Getting started takes a few minutes. See how it works. Want to leave it to us? Managed onboarding.

Yes. Under the Financial Administration guidance (e-invoicing FAQ 9/DPH/2025/IM, examples 36 and 73) a company has exactly one receiving provider in the central SMP but may send through several providers at once; which one sends is a matter of your accounting system. To send through Verteco we require the verification token (an FS recommendation for providers), which you obtain by selecting Verteco on the FS portal; that does not overwrite your current provider's SMP record, and in the portal you can mark that receiving stays there on purpose. To move receiving to us, your current provider issues a migration code and the switch has no downtime (Migration from another provider). Switching providers means: terminate the contract, deregistration by the old provider within 3 working days, migration code; the Financial Administration notifies nobody in between.

Yes. The provider selection in VPDS can also be performed by an authorised representative (typically an accountant). The app uses the Financial Administration portal authorisation model: the representative signs in with their own OIZ account (via slovensko.sk / eID or a plain identifier and password) and sees every subject they act for. Authorisation is granted either online by the client's statutory body (no paperwork), or by filing an authorisation request with a power of attorney under § 9 of the Tax Code; no notarised signature is required and the tax office typically processes it within 1 to 3 working days.

The service costs €2 excl. VAT per company ID per month (billed monthly in arrears for the previous month) and includes everything: receiving and sending e-invoices, the Data archive (originals in the EU, 1 GB included), REST API, webhooks, connectors to accounting/ERP/e-shop systems, multiple company IDs, B2G and reporting to the Financial Administration, up to 1,000 invoices/mo per direction. It is charged for every company ID that sent an invoice in the month or had the Data archive on (the default for new companies). If you only want to receive invoices for free, switch the archive off on the company detail page; document content is then deleted 14 days after arrival and you keep the originals yourself. Every additional invoice (received or sent) is €0,01. An optional managed integration of your system starts at €990 one-off. Prices apply from 1 January 2027; everything is free during the voluntary period. Details in our price list (prices excl. VAT, per company ID).

Because your company has the Data archive on. For new companies the archive is on by default: we keep the original received and issued invoices in the EU for as long as you are with us (1 GB included). €2 excl. VAT per month is charged for every company ID that sent at least one invoice in the month or had the archive on at the end of the month, and only from 1 January 2027.

Only want to receive invoices for free? On the company detail page, Data archive tab, switch the archive off for received and sent documents. Document content is then deleted 14 days after arrival; in the meantime the originals reach you by e-mail or webhook and you keep them yourself. Companies that switched the archive on before 10 September 2026 keep archiving for free until they change the setting. Details: Data archive.

Receiving without the archive is free: a company ID whose owner switches the Data archive off on the company detail page and sends nothing pays nothing, up to 1,000 received invoices/mo (fair use, delivery is never blocked), including the Peppol Box (invoice inbox), EN 16931 validation and automatic receiving-side reporting to the Financial Administration (C5/TDD). This satisfies the legal obligation to receive e-invoices. Document content is then deleted 14 days after arrival and you keep the originals yourself. For new companies the archive is on by default (originals kept in the EU, 1 GB included); with the archive on or with sending, the service is €2/mo per company ID.

The basic services have a fair-use limit: receiving without the archive is free up to 1,000 invoices a month and the complete service costs €2/mo per company ID (receiving, sending and the Data archive, including the API and connectors, up to 1,000 invoices/mo per direction; every additional one is €0,01). We want mandatory e-invoicing not to be yet another unnecessary cost for small companies, so we have pushed prices to the minimum: we operate our own Access Point with no middlemen, which is what lets us afford it. We earn on volume (€0,01 per invoice over the limit), on the archive and on optional managed system integration (from €990). If you would like to connect an accounting, ERP or e-shop system, get in touch.

Yes. A new company starts with the Data archive on (€2/mo per company ID from 1 January 2027; everything is free until the end of 2026). If you only want free receiving, switch the archive off on the company detail page; you can switch the archive or sending on at any time later, with no lock-in. Signing up during the voluntary period means you are ready well ahead of the mandate.

C5 reporting (TDD, Tax Data Document) is a tax report that is sent to the Slovak Financial Administration as part of e-invoicing. The portal generates and sends it automatically; it is included in the price of both sending and custom integrations, so there is nothing extra for you to do.

Nothing gets blocked: invoice delivery keeps working; the 1,000/mo limit is fair use, not a hard cap. Every invoice over 1,000/mo (received or sent) is just €0,01. Transparent, no surprise bill (usually lower than the per-document rates commonly published on the market, €0,05–0,50). For large volumes or connecting your own system, get in touch. We will set up a managed integration, but the price per invoice stays the same.

No. The portal is a web application: just register and work through your browser. No installation, and you are not tied to us in any way. For automation there is a REST API + webhooks, included in the €2/mo package (not an add-on).

Yes. The REST API, webhooks and connectors to common accounting/ERP/e-shop systems are included in the package from €2/mo (including SAP integration via API), so invoices flow straight from your system. Without an integration you can also invoice through the web dashboard. Want to leave the integration to us? We will set up a managed integration from €990 one-off (including setup and testing); then you run on €2/mo + €0,01. Write to us.

Yes. We are a certified provider listed in the official register of the Slovak Financial Administration (PA SK ID EFSK000031, verifiable at vpds.financnasprava.sk) and we operate our own certified Peppol Access Point (Seat ID PSK001128, category 2b). We have successfully passed all 19 of 19 OpenPeppol conformance tests and we are in production. Every document is server-side validated against EN 16931 and Peppol BIS Billing 3.0.

We operate our own certified Slovak Peppol Access Point (Seat ID PSK001128, certified provider PA SK EFSK000031): your invoices enter the network directly, with no intermediaries. That means a lower price, support in Slovak, data in the EU, and a single contract directly with the network operator. And if you want to offer e-invoicing to your clients under your own brand, the same Access Point can run behind your service (white-label).

You are not locked in with us in any way. Peppol is an open standard: your company ID is registered in the network as a portable participant (Peppol Participant ID). You can move to another certified Access Point at any time; when you switch, we deregister you from the national SMP and export your data. No exit penalties, no locked formats.

Yes. All data is hosted in the EU (Frankfurt data centre) and processed under GDPR. Transfer is encrypted (TLS), we have Art. 28 GDPR agreements with our processors, and we never sell your data. Details in our privacy policy.
