Kador is a brand for good, dependable software — tools that do exactly what they promise and work the same way every time, wherever you are. Your privacy comes first, your data stays yours, and pricing stays honest. The kind of software you can trust and simply get on with your day.
A professional invoice in a minute — no sign-up.
A web app that turns a simple form into a polished invoice, with a live preview as you type. Eight templates, your own logo, stamp and signature, discounts, taxes and bank details, and one-click export to PDF or XLSX with no watermark. Nothing to install and no account to start — everything you type stays in your browser. An optional PRO plan saves your company profile, clients and invoice history.
Clean and repair messy CSV files, right in your browser.
A web-based tool that detects and corrects formatting errors, broken delimiters, encoding issues and malformed rows in your own CSV files, then exports a valid, ready-to-use CSV. Sold as a SaaS subscription.
Kador is the brand under which I now build independent software products for the global market. It carries the engineering approach I refined over 15+ years of shipping software — focused tools that each solve one problem well.
I founded my software company in 2015 and ran it for over a decade, building monitoring systems and EdTech platforms on PHP/Yii2 and MySQL. One of them won a national industry award.
I also wrote and published a book on digital transformation in education, and took part in international EdTech pilots in Austria and Finland.
Between 2023 and 2025 I sold the company's products to strategic partners and wound it down as I moved to building for an international audience.
Kador is the next phase — focused products for a global audience. The first step is taken; more will follow.
