I want to build an all-in-one monetization platform for developers. The main idea is to let them sell SaaS subscriptions and digital products without having to worry about the complicated business stuff.

Key features should include selling access to private GitHub repositories, exclusive Discord channels, file downloads, and software license keys. It's really important that the platform acts as the "merchant of record," so it needs to handle all the billing, receipts, and customer accounts automatically. Crucially, it must also manage global sales tax and VAT, which is a major headache for individual creators.

For the tech stack, let's build a modern full-stack application. The backend can be Python with FastAPI, and for the frontend, let's use Next.js with React and style it with Tailwind CSS. Developers using the platform will need a clean dashboard to manage their products and see how much they're earning.
