You pay only for documents actually sent and received. €0 monthly fee, €0 setup, no commitment.
A ready-made connection for your accounting software. No development of your own.
A standardised interface for Slovak accounting software.
REST API, SDKs in 6 languages, webhooks and several companies under one key.
All three ways are billed by the same price list below.
The more documents per month, the lower the price.
How it is calculated: each price applies only to the documents within its band. If a company sends 40 invoices through the API in a month and receives no API document, it pays for 40 outbound documents: 40 × €0.10 = €4.00. This is not a prepaid bundle.

Activation is subject to verified operational and staffing readiness.
