Osu is a cutting-edge business management and payment app for sole traders, the self-employed, and micro businesses, allowing them to easily manage their clients, take control of their schedule, issue invoices, take client payments and more.
Within the Osu app users have access to a suite of business management tools - a laser-focused CRM for client contact details, notes, and payments history, a booking and calendar tool, automatic reminders for late paying customers, modern professional invoicing, and more.
For payments, Osu’s core payments technology allows users to create and send secure payment requests to their clients. Clients can then pay in 3-clicks and the money is transferred instantly and directly to the Osu user's bank account with zero transaction fees.
Osu leverages Open Banking APIs to connect businesses and their customers for secure and instant account-to-account payments.
It means customers can authenticate and confirm payments directly with their own bank, without exposing any sensitive information to any third party – Osu included. What’s more, by automatically connecting the payment information to the bank itself, there’s no risk of typing in incorrect account numbers or amounts – just 100% accuracy.
For businesses it means zero transaction fees, truly instant settlement, and the near total elimination of fraud and chargebacks.
