ePošťák is a certified Peppol Access Point for Slovakia. With Enterprise API you pay for documents actually sent and received. With web interface plans you get a monthly subscription with a fixed number of sends.
For integrators, ERP systems and developers. Volume-based API billing has applied since June 1, 2026 based on documents actually sent and received. Web plan rules do not apply to Enterprise API, Connector/API or white-label use.
SAPI follows the same API pricing; with Enterprise API the integrator pays one consolidated bill for connected companies, while with SAPI the end customer pays through their own account.

All prices are listed excluding VAT.
API documents are billed separately according to the current API pricing. Free receiving in the web interface in SMB programs does not apply to white-label.
Custom domain / branded URL is included for every white-label partner. A higher tier does not change the white-label benefit set.
The partner can present and provide the service to clients under its own brand. ePošťák / Kaja Solutions s.r.o. provides the certified technical backend, Peppol delivery, monitoring and operations. In some places on the Financial Administration portal or in official lists, Kaja Solutions s.r.o. / ePošťák may be listed as the certified delivery service provider.
An active company is each unique company ID / tax ID / VAT ID / Peppol Participant ID that is activated in production mode under the white-label partner in a given month and can send or receive documents through the service.
When the active-company limit is exceeded, the partner moves to the corresponding higher white-label tier from the next billing period. Existing document delivery is not disabled because of the limit overage. ePošťák reserves the right to pause activation of new companies until the partner moves to the corresponding tier.
01Example: A partner has 18 active companies and processes 2,000 documents in a month. It pays €199 excluding VAT for White-label 20 + the API price for 2,000 documents according to API pricing.
02Example: A partner grows to 42 active companies. From the next billing period it moves to White-label 50 for €349 per month excluding VAT + the API price for documents.

In your customer flow you appear under your own brand. In some places on the Financial Administration portal or in official lists, however, Kaja Solutions s.r.o. / ePošťák may be listed as the certified delivery service provider because it provides the certified technical backend.
We count the number of unique active companies in production mode under your white-label program. One company with multiple users counts as one active company. A group with multiple company IDs is counted by the number of unique company IDs / identifiers.
From the next billing period you move to the corresponding higher white-label tier. Existing delivery is not disabled, but activation of new companies may be paused until the correct tier is set.

Peppol is the international network for electronic invoicing. An Access Point (AP) is your gateway in and out of the network. From 1 January 2027, electronic invoicing is mandatory for B2B in Slovakia — without an AP you cannot reach recipients.
Web interface plans Standard and Business have no subscription fee until 31 Dec 2026 and start billing from 1 Jan 2027. Enterprise API/integrator usage is billed from June 1, 2026 based on documents actually sent and received.
The price per document drops with volume. For integrators, volume aggregates across all linked companies, so you progress to lower tiers faster. For volumes above 5,000 docs per month we'll send a custom quote.
Yes. The Free program has a monthly limit of 500 received and 5 sent documents. After the limit is exceeded, new documents are not shown in the interface and sending is suspended; Peppol receipt continues in the background and documents become available after switching to a paid program.

Free receiving in SMB programs does not apply to Enterprise API, Connector/API, white-label or other programmatic or bulk integration use. Such use is governed by Enterprise API pricing or a separate agreement.
