Main features

• Payments: single purchases, subscriptions, metered usage and time-based billing, using checkout widgets that drop into an app.
• Merchant of Record: tiun processes payments, handles tax compliance and chargebacks, and pays out monthly.
• Customer database: each user's subscription status kept with their profile, plus event tracking, transactional emails and invoices.
