Accept card payments only if you want to

You may have the occasional customer who insists on paying by card. So we've partnered with Stripe to give you the choice of accepting cards when needed. Like all card payment processors Stripe charges fees, but we won't add a penny extra.

And keep in mind, you can take payments without accepting cards, ever. With our inbuilt payment technology that’s available from the moment you get started, customers can pay instantly from their bank account with no transaction fees at all.

Take card payments

Make life easier for your customers

No-one enjoys bank transfer faff, rushed trips to the nearest ATM, or handing over card details. Our core payment technology makes everything simpler, faster, and more secure.

Customers click a link, pick their bank, and confirm the payment with Touch or Face ID. We think cards are old school. Once your customers pay our way, they’ll probably agree.

What is Osu?

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.

How do payments work with Osu?

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.
