InvoiceOcean: key info


InvoiceOcean is a SaaS e-invoicing tool founded in 2013 and based in Warsaw, Poland. Our product is a simple application that allows its users to issue a variety of invoice-related documents online. We include companies like Zoho, Freshdesk, Xero and Debitoor among our competition.  


What differentiates InvoiceOcean from other e-invoicing apps is its universal and adaptable capabilities. The application lets issue bilingual invoices from a wide range of available languages and converts prices to all world currencies, including Bitcoin.


InvoiceOcean was ranked 8 on a list of 20 Invoice Solutions That Offer More Than Just Invoicing by and 13 on the list of 27 Free Invoicing Tools for Businesses on a Budget by


InvoiceOcean is a side project by the creators of Fakturownia, the Polish version of the app. It quickly attracted its own user base and motivated us to launch two new language versions of the software: for Spanish-speaking users and for the German market. The app is already used by more than 150 000 users around the world.


InvoiceOcean's team is currently made up of Marcin Stefaniak (CEO), Michał Stefaniak (CMO), Paweł Deryło (CTO), Maria Seta, Małgorzata Kozicka, Łukasz Kalinowski, Piotr Wojciechowski and Maciej Satkiewicz. Our founders were featured on the list of 50 Most Creative People in Business 2016 published by Brief Magazine.
