As answered by people managing CommitCat and 1FAKTURA.sk.
1FAKTURA.sk's answer:
1FAKTURA is built specifically for Slovakia's mandatory e-invoicing rollout under Act 385/2025 (from 2027). It generates compliant e-invoices in UBL 2.1 and PEPPOL BIS 3.0, creates QR PAY (Pay by Square) payments, integrates with 8 Slovak banks, and exports directly to Pohoda, Money S3 and KROS. The interface is fully available in Slovak, Czech, English and Ukrainian — including native Ukrainian support, which no other Slovak invoicing tool offers.
1FAKTURA.sk's answer:
Most Slovak invoicing tools charge extra for e-invoicing and Peppol, or aren't ready for the 2027 mandate at all. 1FAKTURA includes UBL 2.1 / PEPPOL BIS 3.0, QR PAY and an audit log in the price, has a genuinely free-forever plan (Štart, no credit card), and is the only one with a full Ukrainian interface and support — important for the large community of Ukrainian entrepreneurs in Slovakia.
1FAKTURA.sk's answer:
1FAKTURA was founded by Andrii Karutsenko, a Ukrainian entrepreneur in Slovakia who saw first-hand how confusing Slovak invoicing and VAT rules are for newcomers and small businesses. With the EU-wide shift to mandatory e-invoicing (ViDA) and Slovakia's Act 385/2025 arriving in 2027, the goal was to build a simple, affordable, multilingual tool that makes any business compliant in minutes.
1FAKTURA.sk's answer:
Slovak freelancers (živnostníci) and small businesses that need to issue compliant invoices fast and get ready for mandatory e-invoicing. Also accountants and bookkeepers who process invoices for multiple clients, and Ukrainian entrepreneurs running businesses in Slovakia.
1FAKTURA.sk's answer:
Next.js (App Router), React and Tailwind CSS, deployed on Vercel and monitored with Sentry. E-invoicing is based on the UBL 2.1 and PEPPOL BIS 3.0 standards; payments use the Slovak QR PAY (Pay by Square) standard.
