BillingSDK is an open-source collection of production-ready React components designed to help developers implement billing and monetization features quickly.

It provides prebuilt UI blocks for pricing tables, subscription management, usage tracking, invoices, cancellation flows, and customer billing dashboards.

The platform is built on top of modern frontend tools like React, TypeScript, Tailwind CSS, and shadcn/ui, and is tightly integrated with payment providers such as Dodo Payments (and supports Stripe in certain setups). It also includes a CLI that scaffolds full billing systems, generates API routes, and installs components directly into Next.js or other supported frameworks.

BillingSDK focuses on reducing the complexity of building SaaS billing systems by providing composable UI components and backend-ready templates, enabling developers to ship subscription-based products faster without rebuilding billing infrastructure from scratch.

Key features include:

• Prebuilt React components for pricing, subscriptions, and billing dashboards
• CLI tool for project initialization and component installation
• Full-stack templates with API routes and webhook handling
• Integration with payment providers (Dodo Payments, Stripe support)
• Usage meters, invoices, cancellation flows, and plan management UI
• Type-safe, customizable components built with shadcn/ui

Common use cases include:

• Building SaaS billing systems
• Adding subscription plans to web apps
• Managing user payments and invoices
• Ttracking usage-based pricing
• Rapidly scaffolding monetization flows in React/Next.js applications
