Invoices arrive in your mailbox
Received invoices look like emails. You can also send an ordinary PDF — we take care of the rest.
How it works
See how the whole process works.
An invoice arrives in your mailbox, you check it, and with one click you issue and send a new one — just as you know it from email.
A new e-invoice arrives in the mailbox and you open its verified detail. You issue your own invoice from a PDF: OCR reads the customer, items and amount, you check the data and send it. The walkthrough is shown in Slovak.

◆ FAQ
Frequently asked questions
An e-invoice is an invoice in structured XML format (EN16931, UBL) that your accounting software processes automatically. Unlike PDFs or scanned invoices, it contains machine-readable data — no manual data entry, reduced error risk.
From 1 January 2027, VAT payers must issue and receive e-invoices for domestic supplies specified by law. Recipients to whom those suppliers must issue an invoice must also be able to receive it.
Use the provider selection link on the Slovak Financial Administration portal, sign in with your Slovak ID card or login ID and password, enter your company details, and select Kaja Solutions s.r.o. (ePošťák). Then click the activation link sent by email and finish registration on our website.
Yes, receiving in the web interface is free within the Free program limits (500 received and 5 sent invoices per month). You pay for sending, API, automated, or bulk integration use according to the current price list.
No. If your software can create a PDF, upload it to ePošťák, review the data extracted by OCR, and send it as a Peppol e-invoice. You can also create the invoice directly in ePošťák or connect your system through the API.
Free, Standard, and Business plans have no monthly fee in the regular web interface until 31 Dec 2026. From 1 Jan 2027 they are billed according to the current price list. API, Connector, and integration use follow separate pricing.
Yes. Receiving obligations also cover taxable businesses that are not VAT payers and legal entities to whom a supplier must issue an e-invoice. Having to receive e-invoices does not automatically mean having to issue them.
Peppol is a European network for secure exchange of electronic documents between businesses (B2B) and public institutions (B2G). In Slovakia, the Peppol Authority is the Financial Directorate of the Slovak Republic, responsible for accrediting service providers (Access Points) and managing national rules.
ePošťák Bridge is a new product in preparation for connecting your system to Peppol. Planned inputs include API, SFTP, Bridge and email, with format processing and status returned to the ERP. Availability will be announced when the product is ready. The existing Connector remains unchanged.
Connector fits an ERP that hands over invoice data as JSON and leaves the whole flow to ePošťák. SAPI fits systems that already create a ready-made UBL 2.1 document. Enterprise API provides detailed control over documents, events, webhooks and multiple companies. Existing integrations do not need to migrate. ePošťák Bridge is a separate product in preparation.
SFTP, Bridge and email are planned input channels for ePošťák Bridge. We can discuss the method, format and status return during a consultation. This is not an announcement of new features for the existing Connector.
Existing APIs provide status queries, events or webhooks depending on the chosen interface. For ePošťák Bridge we are preparing status, error and delivery-evidence feedback linked to the original ERP document.
