Slovakia eFaktura: First Conference Clarifies Practical Preparation for the 2027 Mandate

Slovakia’s first regional eFaktura conference was fully booked, showing strong demand for practical guidance before the 2027 E-Invoicing mandate. The Financial Administration focused on digital postmen, software connections and simple solutions for different business sizes.

Slovakia’s Financial Administration has completed the first event in its September 2026 regional eFaktura conference series, with the fully booked conference in Gbeľany near Žilina attracting accountants, sole traders, small and medium-sized businesses and larger companies. The event did not introduce a new E-Invoicing obligation or change the implementation timetable. Its purpose was practical: to show businesses how to prepare for eFaktura and how the new process can connect with existing accounting and invoicing systems before the mandatory phase begins on January 1, 2027.

This makes the September 8 update different from the earlier announcement of the conference series. The new information is that the first conference has now taken place and demand for implementation guidance is high. The Financial Administration also provided more detail on the solutions businesses can use, including certified delivery service providers, accounting or invoicing system connections and simpler web or mobile options.

The conference focused on implementation rather than repeating the general concept of electronic invoicing. Financial Administration specialists from taxation, information technology and digitalization explained the process from selecting a certified “digital postman” to connecting that service with an accounting or invoicing system.

The available options are intended to cover different types of businesses. A company processing a large number of invoices may integrate eFaktura with existing software, while smaller businesses with only a limited number of invoices may use simpler web or mobile solutions. The Financial Administration also confirmed that free solutions are available for smaller entrepreneurs.

This matters because preparation does not necessarily mean that every business must build a complex new technical solution. The appropriate setup will depend on invoice volume, existing software and the way invoices are currently created and processed.

The conference also gave participants space to ask questions about their own business processes. According to the Financial Administration, accountants formed the largest participant group, but sole traders, SMEs and larger businesses were also represented. Implementation questions are therefore relevant well beyond large companies with complex ERP environments.

For retailers, the main question remains how E-Invoicing will fit into existing sales and invoicing processes. The eFaktura regime should not be confused with ordinary retail fiscalization or the eKasa process. A retailer may continue to use eKasa for retail transactions while also needing a separate structured E-Invoicing process for transactions that fall within the mandatory invoice rules.

This distinction is relevant where a retailer issues B2B invoices from a store, e-commerce channel, ERP system or central accounting system. Businesses need to know where the legally relevant invoice is created, which system contains the customer information and how invoice data will be transferred to the selected certified delivery service.

POS, ERP and accounting software providers should therefore review the connection points between their systems. The first conference confirms that preparation is not only about choosing a digital postman, but also about how that service will connect with the existing invoicing or accounting environment.

From a retail compliance perspective, the difficult part is likely to be keeping different document and transaction processes clearly separated. An eKasa receipt or ordinary retail transaction should not automatically be treated as a structured E-Invoice simply because both originate from the same commercial environment. Retailers that issue invoices through stores should therefore map the process before implementation.

The immediate impact is mainly preparatory. Businesses that will issue or receive eInvoices need to decide which technical route is suitable and whether their existing software can support it. Larger businesses may need integration between ERP or invoicing systems and a certified delivery service, while smaller businesses may be able to rely on simpler tools.

For software providers, the conference also confirms that implementation is not limited to invoice format alone. Identification of senders and recipients, reliable delivery and the connection between invoice creation and the delivery service are part of the wider process businesses need to understand.

The Financial Administration presented eFaktura as a way to reduce manual data entry, lower the risk of errors and speed up document processing. It also linked electronic invoicing with improved payment discipline, considering that a large share of invoices in Slovakia are currently overdue. These are expected operational benefits rather than new legal requirements and should be separated from the compliance rules themselves.

In our view, the strongest message from the first conference is that businesses should now move from general awareness to process-level preparation. The legal requirement is already known; the implementation challenge is deciding how invoice creation, customer identification, accounting and electronic delivery will work together without creating confusion with existing retail fiscalization processes.

What should affected businesses prepare now?

Retailers, accounting teams and software providers should first identify which parts of their current process create or receive invoices. They should then determine whether they need an integrated accounting or ERP solution, a simpler web or mobile option, or another available service connected to a certified digital postman.

Businesses should also review whether store-level B2B invoicing, e-commerce invoicing and central billing follow the same process or different ones. Testing these flows before the mandatory phase should help identify missing customer data, integration issues or unclear responsibilities between POS, ERP and accounting systems.

The regional conference series continues in Trenčín, Prešov, Košice, Piešťany, Nitra and Banská Bystrica. Businesses can also use the Financial Administration’s eFaktura information section, consult the list of certified delivery service providers and intermediaries, and access webinar recordings through the Financial Administration Academy.
