Stripe is a popular fintech platform that offers various tools to manage online transactions, including Stripe Billing for managing subscriptions and calculating pricing. While it's well-suited for B2C businesses, its suitability for B2B companies may be limited due to certain drawbacks such as increasing percentage fees, vendor lock-in with Stripe's ecosystem, event-based architecture issues, and inflexibility in billing periods. Togai is an alternative platform that offers more flexibility and comprehensive support for complex pricing models, making it a potential solution for B2B companies seeking advanced billing solutions.
