Overview
CalcoloOK and PaymentKit are two distinct tools designed for very different audiences. CalcoloOK is a free online calculator for Italian tax codes (codice fiscale), aimed at individuals who need a quick estimate. PaymentKit is a comprehensive billing platform for businesses, offering payment orchestration, subscription management, and revenue recovery.
CalcoloOK focuses on simplicity and privacy: all calculations happen in the browser, and no data is sent to servers. It's ideal for Italian residents, professionals, and students who want to understand or verify a tax code format. PaymentKit, on the other hand, is built for SaaS and e-commerce companies that need to handle complex payment flows, reduce churn, and maintain control over their revenue infrastructure.
