Faktury online is Slovakia’s first online invoicing service of its kind and scale. The project was founded back in 2009 not as a marketing concept or a quick business idea, but out of the founder’s real-world need.
At a time when accounting documents were typically created using local software installed on specific computers, there was a need for a simple solution for creating documents — especially invoices — that would be accessible, always up to date, and usable from anywhere without unnecessary complications.
In 2009, Slovakia introduced the euro to replace the Slovak koruna, which meant that existing installed systems required updates that had to be manually downloaded and installed — if they were available at all. This situation was the main impulse behind the creation of Faktury online.
From the very beginning, the project developed naturally in cooperation with its users. The first users — who at the time were not customers in the commercial sense — actively used the system and provided feedback and suggestions for improvements. Thanks to this, Faktury online gradually expanded, became simpler to use, and gained increasing popularity among sole traders and small and medium-sized businesses. The project’s growth was built on real usage and practical experience.
That is also why the term “Faktury online” became an established phrase for online invoicing as such. Many competing solutions now target this name through ads, landing pages, and paid campaigns. However, there is only one original project, and its reputation was built gradually through the experience and recommendations of its users.
The philosophy of Faktury online is simple and consistent. We do not use grand claims and we do not force anyone to use the system. Each user should discover for themselves that it is a functional, reliable, and practical solution that saves time and reduces administrative workload. That is why the entire system is designed to be intuitive, fast, and easy to use without lengthy training.
Since the project was not created primarily as a commercial product, but as a tool for real use, the same philosophy is reflected in the pricing. Faktury online has long offered one of the best value-for-money ratios on the market. For a fair price, users get extensive functionality without unnecessary limitations, plus a free period of up to one year during which they can fully test the system in real conditions.
