Tino Hakkarainen is a self-taught IT engineer specializing in e-invoicing. He helps businesses move from manual invoice handling to automated flows, whether invoices arrive from an ERP or as a PDF in an inbox. Those PDFs are converted into structured data and imported into software that carries each invoice through to payment with as few human touchpoints as possible. Today, he focuses on transitioning companies to AI-driven capture technology so even messy, inconsistent invoices can be read accurately and processed automatically. Based in Espoo, Finland, he works in both Finnish and English.
