Hey! 👋 I built Corebill because every invoicing tool I tried was either too complex, too ugly, or not built with developers in mind. The core idea is simple: what if your billing platform had an AI agent that just did things for you? Instead of navigating menus to create an invoice, you just say "Create an invoice for Acme Corp for 3 months of the Business Plan" — and it's done. The agent looks up the client, finds the right service in your catalog, and generates the invoice. Under the hood, Corebill is also a proper developer platform — REST API with full documentation, API keys with role-based permissions, webhooks, and a clean design inspired by tools like Supabase that developers actually enjoy using. Would love your feedback on the AI agent experience and what tools or integrations you'd want to see next. Happy to answer anything!
