eInvoice for Microsoft Dynamics 365 Business Central in Slovakia
From 1 January 2027, Slovak companies will face a major change in invoicing. An electronic invoice will no longer be just a PDF document sent by email. Invoices will be issued, sent and received in a structured electronic format that information systems can process automatically.
For companies using Microsoft Dynamics 365 Business Central, this means preparing the ERP system for a new way of exchanging invoices electronically.
The good news is that Business Central already includes technologies for working with electronic documents. However, the Slovak eInvoice is not just about creating an XML file. The entire process needs to be addressed – from data in Business Central, through invoice validation and sending, to receiving, checking, approving and posting incoming invoices.
SAPI-SK: One Standard API for All Digital Access Points
Starting on 1 January 2027, electronic invoicing (eInvoice) will become mandatory for selected business transactions in Slovakia. Companies and ERP vendors will need to exchange electronic invoices through the Peppol network.
For software vendors, this raises an important question:
Should an ERP system integrate separately with every Peppol Access Point, or is there a common interface?
The answer is SAPI-SK (Standardised Access Point Interface – Slovakia), a standardized communication interface designed to simplify integration between ERP systems and certified Peppol Access Points.
