From 1 January 2027, invoices between Slovak companies are exchanged as e-invoices through the Peppol network. ViaSpaces is your digital postman: it delivers your e-invoices, receives the ones sent to you, and reports them to the Financial Administration.<\/p>\n\n\n\n

Peppol connects companies across Europe. ViaSpaces currently supports the Slovak Peppol network. Support for other European countries is in preparation.<\/p>\n\n\n\n

What Changes from 1 January 2027<\/h2>\n\n\n\n

An e-invoice is an invoice in a structured electronic format. Accounting software reads it automatically. A PDF sent by email is not an e-invoice.<\/p>\n\n\n\n

Who<\/th>Obligation<\/th><\/tr><\/thead>
Every company and sole trader with a DI\u010c<\/td>Receive e-invoices through a digital postman<\/td><\/tr>

Your digital postman (ViaSpaces)<\/td>Deliver and receive e-invoices and report their data to the Financial Administration<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Each company has one digital postman for receiving. Your company’s address in the Peppol network is built from your DI\u010c (for example 0245:2020123456<\/code>). Your suppliers find you by your DI\u010c; they need no other details.<\/p>\n\n\n\n

In ViaSpaces, e-invoices are separate documents, marked Electronic invoice<\/strong> and created from templates with the Peppol icon. You choose which documents you create and send as e-invoices. For each e-invoice you send, ViaSpaces checks it, delivers it through Peppol, and reports it.<\/p>\n\n\n\n

Activating Peppol<\/h2>\n\n\n\n

Activation connects your company to the Peppol network with ViaSpaces as your digital postman. You need a DI\u010c filled in your company details.<\/p>\n\n\n\n

You can activate Peppol in two places:<\/p>\n\n\n\n

Where<\/th>When<\/th><\/tr><\/thead>
Registration of a new company, step Business numbers<\/strong><\/td>During sign-up. Switch on Activate Peppol Delivery<\/strong>.<\/td><\/tr>
Settings \u2192 Business Account \u2192 Peppol<\/code><\/td>At any time later. Click Activate Peppol Delivery<\/strong>.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

[Screenshot: Registration of a new company, step Business numbers \u2014 fields Business reg. no., TAX registration number, VAT registration number; the card Activate Peppol Delivery switched on and expanded with the options Register through ViaSpaces and I have a registration code; Continue button; progress steps on the right with Business numbers highlighted.]<\/p>\n\n\n\n

For a Slovak company, choose one of two options:<\/p>\n\n\n\n

Option<\/th>Use it when<\/th><\/tr><\/thead>
Register through ViaSpaces<\/strong><\/td>You have not chosen a digital postman yet. ViaSpaces submits the request to the Financial Administration for you. Complete the preliminary steps on financnasprava.sk first.<\/td><\/tr>

    \n
  1. Open Settings \u2192 Business Account \u2192 Peppol<\/code>.<\/li>\n\n\n\n
  2. Click Activate Peppol Delivery<\/strong>.<\/li>\n\n\n\n
  3. Choose Register through ViaSpaces<\/strong> or I have a registration code<\/strong>.<\/li>\n\n\n\n
  4. For a registration code, enter it in Registration code<\/strong>.<\/li>\n\n\n\n
  5. Confirm. The Peppol tab shows your company as connected, with your Peppol ID.<\/li>\n<\/ol>\n\n\n\n

    [Screenshot: Settings \u2192 Business Account \u2192 Peppol before activation \u2014 title Activate Peppol Delivery, short explanation, the two options Register through ViaSpaces (with the link to financnasprava.sk) and I have a registration code (with the Registration code field), Activate button.]<\/p>\n\n\n\n

    Activation for companies registered in other European countries is in preparation. It will use the company identifier of the country’s Peppol registry instead of the Slovak DI\u010c.<\/p>\n\n\n\n

    \n

    \u2139\ufe0f Only an Administrator of the company account activates or changes Peppol. An accountant with a power of attorney chooses ViaSpaces on the Financial Administration portal on the company’s behalf; to complete activation in ViaSpaces, the accountant needs the Administrator role.<\/p>\n<\/blockquote>\n\n\n\n

    \n

    \u2139\ufe0f Without a DI\u010c, ViaSpaces displays a notice and activation stays unavailable until the DI\u010c is filled in.<\/p>\n<\/blockquote>\n\n\n\n

    [Screenshot: Peppol tab with the notice that Peppol registration is available after the DI\u010c is filled in.]<\/p>\n\n\n\n

    Sending an Invoice via Peppol<\/h2>\n\n\n\n

    You send an e-invoice from Document Editor. You decide which documents to send via Peppol: only documents created from a Peppol template carry the Electronic invoice<\/strong> badge and the Send via Peppol<\/strong> button.<\/p>\n\n\n\n

    \"Document<\/figure>\n\n\n\n
      \n
    1. Click Create New Document<\/strong> and choose a template marked with the Peppol icon.<\/li>\n<\/ol>\n\n\n\n

            Receiving Invoices<\/h2>\n\n\n\n

            ViaSpaces receives every e-invoice sent to your company. No action is required to receive it.<\/p>\n\n\n\n

              \n
            1. A supplier sends an e-invoice to your company.<\/li>\n\n\n\n
            2. ViaSpaces checks it, stores it, and reports it to the Financial Administration for you.<\/li>\n\n\n\n
            3. You receive a notification about the new document.<\/li>\n\n\n\n
            4. The invoice appears on the Dashboard as a readable document.<\/li>\n<\/ol>\n\n\n\n

              [Screenshot: Dashboard with a received e-invoice in the list \u2014 supplier name, Peppol icon, amount, date; notification about the new document in the top bar.]<\/p>\n\n\n\n

              You open, approve, and export a received e-invoice like any other document. The Dashboard export provides it as PDF.<\/p>\n\n\n\n

              When the supplier is new to you, ViaSpaces adds it to Business Partners automatically, marked with the Peppol icon.<\/p>\n\n\n\n

              Every e-invoice delivered through Peppol is received; the network has no option to refuse it. An incorrect or unexpected invoice is settled directly with the supplier, usually by a credit note from the supplier.<\/p>\n\n\n\n

              Correcting an Invoice<\/h2>\n\n\n\n

              A sent e-invoice stays with the customer permanently. You correct it by sending another document.<\/p>\n\n\n\n

              What is wrong<\/th>How to correct it<\/th><\/tr><\/thead>
              Amount or VAT<\/td>Send a Credit Note<\/strong> for the original invoice, then a new correct Invoice<\/strong>.<\/td><\/tr>

              The Credit Note template contains a field for the original invoice number, which links both documents.<\/p>\n\n\n\n

              Reporting to the Financial Administration<\/h2>\n\n\n\n

              ViaSpaces reports the data of every e-invoice sent or received via Peppol to the Financial Administration. You submit nothing yourself for these documents.<\/p>\n\n\n\n

              ViaSpaces stores every sent and received e-invoice with its delivery records. The document history shows when the invoice was sent, delivered, and reported. These records serve as proof for the Financial Administration.<\/p>\n\n\n\n

                From 1 January 2027, invoices between Slovak companies are exchanged as e-invoices through the Peppol network. ViaSpaces is your digital postman: it delivers your e-invoices, receives the ones sent to you, and reports them to the Financial Administration. Peppol connects companies across Europe. ViaSpaces currently supports the Slovak Peppol network.
