How do I connect SAP to the Peppol network?

Through the national SAPI-SK REST interface: the OpenAPI specification, the documentation and a public sandbox are available in our documentation. If you have no development capacity of your own, we deliver a managed custom connection priced by scope.

Do you support S/4HANA as well as Business One?

Yes. The connection through the REST API is independent of the SAP version; typically it is done by exporting invoices to UBL (EN 16931) and calling SAPI-SK. Mapping from IDoc or custom formats is part of the managed connection.

We have several companies (company IDs) in the group, can you handle that?

Yes. One API access can serve several companies, and for groups, SaaS platforms and partners we have a separate cooperation model; see the page Solution for partners.

How much does a managed custom connection cost?

A one-off fee, priced by scope (formats, number of companies, way of connecting). Write to peppol@verteco.digital or call +421 944 488 269 (Mgr. Miriama Mrkávková) and we will propose the exact procedure and price.

How much does it cost?

The service costs from €2/month excl. VAT per company ID (IČO) that sends or has the Data archive switched on (the default for new companies): receiving, sending and the archive of originals in the EU. A company with the archive off that only receives pays nothing (up to 1,000 invoices a month). During the voluntary period before the mandate of 1 January 2027 everything is free of charge.
