The introduction of e-invoicing in Slovakia marks a fundamental change in how companies issue, send, and receive invoices. Starting in 2027, it will become mandatory for all VAT payers. E-invoicing and ERP integration are therefore key topics for companies that want to prepare in time.
For many companies, however, a fundamental question arises: how to implement e-invoicing and ERP integration without disrupting existing processes and without undertaking complex IT projects.
Every company uses a different ERP system, ranging from simple accounting tools to comprehensive ERP solutions. It is precisely this diversity that causes complications with integration, data exchange, and ensuring compliance with new regulations.
Digital Mail Carrier as a Solution for E-Invoicing
The solution is a digital mail carrier, which acts as an intermediary between a company’s ERP system and the government’s e-invoicing infrastructure. This makes the integration of e-invoicing and ERP simpler, faster, and requires no changes to existing processes.
The Roles of a Digital Mail Carrier
Its role is:
ensure compliance with the law
send and receive e-invoices from business partners
report data in real time to the Financial Administration
convert data between different formats
Benefits for Businesses
The company does not need to change its existing ERP system or rewrite its established processes. The digital mail carrier will handle communication on its behalf and significantly simplify e-invoicing and ERP integration.
A versatile solution for various types of businesses
Solutions are appearing on the market that can serve only a certain type of customer or are tied to specific systems.
Solutions for Small Businesses
However, Flowis offers a universal solution that is suitable for both small and large companies. For smaller companies, it offers easy integration with little or no IT intervention, quick implementation, and minimal costs.
Solutions for Large Companies
For larger companies and the enterprise segment, it offers scalability, integration with comprehensive ERP systems, and the ability to handle a high volume of invoices.
One solution for the entire market
The result is a single solution for the entire market, regardless of company size.
E-Invoicing and ERP Integration in Practice
One of the biggest challenges in the field of e-invoicing is integrating different systems—that is, ensuring they can communicate properly with one another and exchange data.
The Digital Mailman as a Translator
In this process, the digital mail carrier acts as a translator. It receives data from an ERP system—such as SAP, Pohoda, Omega, or Helios—transforms it into the required format, and sends it to the government system and the business partner.

Practical Benefits for Businesses
For companies, this means they don’t have to make major changes to their ERP systems, they reduce development costs, and they can deploy the new solution much faster. This allows companies to continue using their existing processes without unnecessary complications.
E-invoicing Requirement Starting in 2027
Starting January 1, 2027, e-invoicing will be mandatory for all VAT payers.
Impact on Businesses
This change will bring mandatory digital communication and increased pressure on both IT and finance departments. Companies that do not have a suitable solution in place will likely have to address the situation under time pressure, which could mean higher costs and a greater risk of errors.
Competitive Advantage
Another significant advantage is a competitive edge, as companies that prepare early will find it easier to transition to the new rules and will be in a stronger market position.

Digitization as the Future of Business
E-invoicing is not just another legal requirement. It represents a step toward the digitization of business processes and the standardization of communication between companies, the government, and business partners.
The Digital Postman as Infrastructure
The digital mailroom is therefore becoming a new infrastructure for modern business, just as important as an ERP system or accounting.
