Basics: working in the portal

Everything a business owner or accountant needs without programming. From the first sign-in to exports for the books.

Getting started (for businesses)

You do not need to be a technician. If you are a sole trader, a limited company (s. r. o.) or an accountant, our portal in your browser is all you need: you receive and issue invoices by clicking, no programming required. This is how it works in three steps:

  1. 1

    Sign up (free of charge)

    Create an account with your e-mail on the registration page. Receiving invoices without the Data archive (Archív dát) is free (up to 1,000 invoices per month); new companies have the archive switched on by default, which costs €2 excl. VAT per company ID per month from 1 January 2027 (switch it off on the company detail).

  2. 2

    Select us on the Financial Administration portal

    To be able to receive e-invoices, choose us as your certified provider (digital postman, digitálny poštár) on the FS portal (VPDS) of the Financial Administration of the Slovak Republic (Finančná správa, FS); the selection is confirmed by logging in with eID or with the FS portal credentials. We then register you in the Peppol network automatically and send you a login e-mail.

  3. 3

    Receive and issue invoices

    Received invoices arrive in the portal and by e-mail. You issue an invoice in the simple editor (like in Word), from Excel (download the pre-filled .xlsx template, add the customer and the lines, upload one or several files at once), or duplicate an existing invoice in a few clicks; the PDF preview button shows the invoice before sending exactly as the buyer will see it. We send the tax report to the Financial Administration (TDD) on your behalf automatically.

One provider for receiving, several for sending: under the Financial Administration guidance (e-invoicing FAQ 9/DPH/2025/IM, examples 36 and 73) a company has one receiving provider in the central SMP but may send through several at once. If you want to keep receiving with your current provider and send through Verteco only, selecting Verteco on the FS portal is enough (it gives us the verification token we require before sending); we do not overwrite your provider's record, and in the company detail you choose "Receiving stays with the current provider (on purpose)" to stop the switch reminders. A provider change follows the FS rules: terminate the contract, deregistration by the old provider within 3 working days, migration code (no downtime); the Financial Administration notifies nobody in between. Switching from another postman: if your company already had another provider, after selecting Verteco on the Financial Administration portal the network keeps delivering to its access point until the record in the national SMP is taken over. Ask the previous provider for a migration code and enter it in the portal on the page Migrate from another provider (linked from My companies, from the company detail and from Add company). The owner or an admin of the company can perform the takeover; the company must be active and verified by the selection on the FS portal. The takeover is immediate and has no downtime, delivery is not interrupted. If you send us the code to peppol​@​verteco.digital, our team performs the takeover from the portal administration. On the Peppol network tab of the company detail you can also switch receiving through Verteco off: we remove the company's record from the central SMP (any provider may register it) and sending through Verteco keeps working; until you switch receiving back on or select another provider on the FS portal, the duty to have a delivery-service provider is not fulfilled. Three changes per hour: on, off and on again go through, so a click made by mistake can be reverted at once; the fourth change waits until an hour has passed since the first.
The Peppol Directory listing (the network's public address book: company name, country, Peppol identifier) is managed in the company detail → Peppol network → Peppol Directory listing. For legal entities we publish the business card at registration, for sole traders only on their choice (VOP 11c.1); an owner or admin can switch it on or off at any time, the change is written straight to the central SMP.
Scheduled export for the accountant: in the company details → Notifications the owner or an administrator sets up to five automatic exports (POHODA, MK-soft, MRP, Money S3/S4, OMEGA, ALFA plus, PROLUC, original XML, ISDOC or CSV; received, issued or both; daily, weekly or monthly on a chosen day and hour; 1 to 5 e-mail addresses). The portal e-mails the export as a ZIP; the first batch holds the documents since the export was created and every further batch continues exactly where the previous one ended, so the accountant never receives a document twice and never misses one. "Send now" mails a batch immediately. The same tab also sets the hour of the daily or weekly digest of received invoices (07:00 by default).

For developers

Technical documentation (API)

The following section is for developers who want to connect their own system (ERP, accounting software, an invoicing app) via the REST API. If you are a business owner and the portal is all you need, you can skip this section.

Day-to-day work in the portal

Where to find what after signing in. Every item links straight to the place in the portal.

Received invoices

Every e-invoice delivered through Peppol is listed under Received invoices: download the PDF, the original XML and the delivery receipt. The e-mail about received invoices follows the company setting: for every invoice (with the PDF and XML attached), as a daily digest at 7:00 (the default for new companies) or weekly; set the address and frequency on the company detail, Notifications tab.

Sending an invoice from the form

Send e-invoice → Form. Before the form opens, the portal checks that the customer is reachable in the Peppol network. Numbering and default values (due days, IBAN, note) come from the invoice settings. Delivery status and the receipt are under Sent invoices.

Send e-invoice →

Bulk sending from CSV

The Bulk sending (CSV) tab: download the template, one row is one line item, invoices are grouped by number. You see a check of every invoice before sending and send only after confirming.

Bulk sending →

Send from a file (Excel, XML, JSON)

The Send from a file tab: every format comes with a sample pre-filled with your company. Excel (.xlsx) looks like an ordinary invoice and can be printed: fill in the yellow cells, save, and upload one or more files at once. A ready-made UBL XML (Peppol BIS 3.0) from your system is sent unchanged; JSON has the same fields as the form and we build the e-invoice from it.

Send from a file →

Exports for your accountant

On the Exports page, download CSV, XLSX, JSON, a ZIP with the original XML documents and accounting-software formats for a chosen company, direction and period.

Open Exports →

The address book fills itself after every sent invoice; in the form you pick a customer with one click and can edit the entries.
