Togai, Recurly, and Stripe Billing are three popular billing platforms for SaaS businesses. Togai stands out for its ability to model monetizable events and provide real-time analytics, making it ideal for B2B companies. It also offers tax automation through integrations. Stripe Billing has a simple, user-centric design with flexible usage-based pricing but may incur higher fees for large transactions and lack robust customer support. Recurly is easy to set up and navigate, with a variety of payment options, but has limitations in feature set and support for complex pricing models. Businesses should weigh the pros and cons of each platform based on their billing complexity, volume, and need for customization.
